I know the screen is turned up, but thats no excuse, my tf101 manages at least 6 hours at the same brightness.
What the hell is going on - where is that improved battery life I purchased?
Something else is the issue. That is very uncommon. No reason it should've drained that much. Even if it is a new device needing battery to go thru more cycles. I'd say try a reset. Maybe your battery meter reporting false info. No way balanced with super ips mode would drain that much just browsing the web. Unless you have some app or widget that draining like crazy. How long have you had this device? What was the last apps or Widgets you downloaded?
Surfing the web does drain the battery the fastest next to display. Plus watching flash videos is a major battery drainer. I'd say check for rogue apps. You can also download better battery stats to see what has really nbeen draining battery the most. I easily get 9-11 hrs of battery on balanced mode doing more than you did.
First of all, the TF101 does NOT have the same screen brightness as the TF201.

http://www.notebookcheck.net/Review-Asus-Eee-Pad-Transformer-Prime-TF201-Tablet-MID.69849.0.html
Average screen brightness of the TF101 is 331.6 cd/m^2 and the TF201 is 484cd/m^2. It's almost FIFTY percent brighter at maximum brightness than the TF101.
The TF201 at 50% brightness has a cd/m^2 average of 305. When Super IPS+ mode is used a maximum average of 514 cd/m^2 is possible.
I'm not interested in a reset at this point, but I am going to download a battery analysis tool because this is crazy.
The last apps I downloaded were an irc client and a like 2 games.
The battery life has never been fantastic - but this is just bad. I've had it about 10 days now... gamestop unit so no returns.
There was no flash, no sound, just web and nothing more.

Your telling me.. I have them right next to each other and there's no noticeable difference between the two...
On .15, I've been running about 15%/hour on heavy browsing, video, gaming (although heavy gaming can push 30%/hour), and about 7.5% on things like ebook reading, light browsing, etc. Standby has been about .375%/hour, which is excellent.
So, the OP's results are an anomaly, clearly. I'd say, do a complete shut down and then restart, and see what happens. Has to be some kind of rogue app or system component causing this.
GAmestop has a 30 day warranty exchange program. If you want you can easily exchange it for another if the battery life doesn't get better. What you reported is something unheard of before. Never heard a battery draining that fast. Better battery stats is the best for battery analysis.

An exchange may help - would be a pity though because I have working wifi and gps w/ 0 lightbleeds. I was considering virtuous, but i haven't unlocked the bootloader yet.
I honestly don't feel a factory reset would change much... maybe its just. 15.

Waiting for a complete discharge first - then I'll charge it up and see if this continues.
here's what bbs says so far if anyone is interested. I haven't updated Boat browser lately so I don't know why it wouldn't have done this before if that was the problem.
Battery still new if only 10 days old. Do the complete discharge like you said then charge up again. I don't think it really needs to be exchanged unless the poor battery life continues. Boat browser is your culprit. You could try switching to another browser. Boat browser might drain more power than others. Try ICS+ browser or opera mobile. I use those n get great battery life. Always make sure your apps are up to date. Updated ones more optimized.
I hope it's not boat D;

I really think you might have something else or a few things running in background you not seeing. Another way tl see is load up the Asus task manager widget. See if any odd apps or anything is running. If so, kill it. Also, make sure you put display to sleep at least 1 minute or less. I have mines set on 30 seconds or sometimes 15seconds. Which means if no activity detected in that time frame, screen will cut off. This can dramatically improve battery life. Also make sure to cut down the frequency of notifications. I have my mail set to 1hr. Which is the Max or longest interval. Or you could cut it off and have it update manually when you open mail up. Also check to make sure you don't have apps that syncing too often. Like Facebook, etc... this can be found in settings. I city my Facebook notifications off. It goes off too much. So instead it'll update whenever I open up the app. Lots of things you can do and check to optimize battery performance. Also live wallpapers can drain. I don't use them. Then its best to leave auto brightness off. Better battery life can be had using manual. Plus even if ips+ is off but still on Max brightness, it'll drain battery fast. I never have my display more then 25% with ips+ off. One thing you can try is to put brightness all the way down. Then cut on ips+. The display is bright n will drain less than cutting brightness all the way up. Someone posted good battery life with that setup. I'm still testing it out.

Will 1 hr notifications affect google voice notifications as well?
Not sure. Don't think so. I think you can set Google voice notifications frequency within the app itself.
Still getting the exact same results 1 hour and 40 mins into a fresh recharge.
I uninstalled boat browser and reverted to stock - stock is draining at the same rate.
I want to try a factory reset - but I really don't want to have to install everything and get it configured right again :/
considering unlocking the bootloader so I can make a nandroid backup - but its risky if its a battery problem instead of a software one.
I ended up getting 5 hours and 6 mins total yesterday after switching power saving halfway throufh and cutting the brightness 30%.
Don't risk warranty unlocking. I honestly don't know why you getting subpar battery performance. Most seem to gget great battery performance. Try a factory reset through settings or stock recovery mode. So it can clear all old data or any bugs might be prevalent.

I'll give it a shot tomorrow night when I get home from college. I installed juice defender ultimate so I'll give that a go in the meantime.
if I factory reset I'm probably going to revert to honeycomb with stock firmware because I have a gut feeling its .15 and ics is only hindering some of my apps from working at the cost of a nicer ui.
As I said I have working gps/wifi so the firmware updates aren't doing me any favors.

I have mines set to always n still get really good battery life.
Op, I heard apps like juice defender n such don't really do much for tablets n may actually cause more battery drain. Reason because depending on your settings in that app, it'll constantly be trying to kill or shut down processes that'll pop right back up. Plus killing of certain processes might cause issue or more CPU strain. It'll be better to just freeze them. Just something I read here on xda. I think of was in the tips & hints section of better battery stats. They said not to use apps like juice defender n such.

What is the deal with this phone? The battery life is not very good at all. I came from a phone that had a 1150 battery and this one has 1600! I am getting almost identical battery life as my old phone. I am running a fully debloated rom at stock clocks with the display turned all the way down and can HARDLY make it through an 8 hour work day. I've narrowed it down to the screen.
I remember reading about amoled when it was first announced and they said it would consume significantly less power than any other display technology. I'm starting to second guess this.
Its either the screen or the dual core processor that's draining this decent sized battery so fast.

Amoled does. From what ive beem read ing super amoled plus.is alot better. The darker the better. Slcd is.a.good option for battery mizers though.
I voided my warranty and your mum.
Yes ive also read that the way super amoled plus works, is there is no backlight and individual pixels light up, so its better to have simple wallpapers with mostly black, would probably give you better battery life, as most of the screen will no be using any energy.
All android devices murder their batteries. It's nothing new get over it lol.
This device gets decent battery life considering it's the most powerful option out currently though.
The general masses do not understand how to set these phones up for optimal battery life. There are threads all over XDA on how to do this.
This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off.

I don't think is the screen alone itself but the dual-core running at 1.2Ghz might eat more battery than your old phone with an smaller battery

You might want to install CPUSpy and BetterBatteryStats (BBS) so you can better diagnose where your battery issues are coming from. 8 hours seems very poor for this device. Use CPUSpy to see how much your device is running in deep sleep - with light usage I usually see around 80% deep sleep. You can use BBS to look for apps causing excessive wakelocks (BBS is available here on xda) to see if a particular app is causing the problem.
Unless you have a hardware problem, I don't think the display is your problem - the display on this device has a smaller percentage hit on battery use than my 3.2" LCD Aria.

Yet you've completely ignored people who have told you to get CPUSpy and BetterBatteryStats to figure out what's keeping your phone awake.
Most likely your phone is not defective, but you've installed an app that's hogging the battery or set up a configuration option that kills it, such as:
Hotmail calendar sync is known to cause massive battery drain due to a Hotmail server side bug
Some Exchange servers are misconfigured and cause major battery drain
Skype is a battery-hogging nightmare. If you absolutely have to use Skype, make sure to take it out with a task killer when you're done with it.
I haven't really pushed my device with screen-on time, however what are your idle battery drain statistics? If you have drain more than 2-3% per hour when the phone is idle (such as overnight), something is very wrong. You should be getting drain on the order of 1% an hour if you leave the phone overnight in moderate signal.

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

Make sure to do the following to get the most accurate data:

Remove from charger

You can still exchange with a new one under 14 days or 30 days. 6 hours with screen on is not absurd on this phone in 12 hours. I have been with screen on with 2:45 hrs and voice with 45 min in 1 day and 8hrs with still 15+ % battery juice left.

IIRC, one of the review or comparison against iPhone4S benchmarked GS2 as 5 to 6 hours of internet browsing which means both screen on and using data. Wi-fi gives it a slightly longer battery life than cell data. Unfortunately, it didn't benchmark video playback time. iPhone4S spec says 8 hours of video. I hope GS2 is close to that. This is play video from local storage, not streaming. So, the data connection battery draw is out of picture. I managed to get 4+ hours of video playback with flight mode on with my old Captivate. Hopefully, GS2 will last longer, e.g. survive a coast to coast flight while still have some juice left for navigation.

He's not lying. I have seen 5 hours of screen on time and still had a little juice left at the end of 16 hour days. And it wasn't a one time deal. Seen it several times, though I usually don't use my phone that heavily. Yesterday I barely used my phone at all and was only down to like 85% after 16 hours.
Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...
What can I do to fix this?
Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...
No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.
Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.
I get over a full day on heavy usage...
No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

I have unrooted phone and get around 17-20 hours heavy usage.
I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so
http://forum.xda-developers.com/showthread.php?t=1075278
you dont need to be rooted to flash new roms via odin
Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.
Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time
Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...
Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....
I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Ok, so I am attaching my screen shots for you to look at..There are 2 of them, as I can't figure out how to take a scrolling screen shot, which I don't think there is a way...but I'm still in the learning process...lol
The time is now, 10:15 am EST. I have turned off GPS. Force Stopped Solitare (Wife likes to play that)and it says: 4h 52m 35s on battery..not sure how to read this? Is this how long it's been on? or that I have battery left?

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.
Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......
You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.
yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:
1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks
7. 10-15 mins of gaming
8. Downloads for 30 mins
8. Auto-sync & background data enabled for 9-10 hrs

Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.
This one is from 49 min unplugged...
As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.
make sure u have latest update thats basically all i did.
good luck.
I would like to get some more information on the WiFi battery drain problem after the .21 update. Some users report decreased bat life due to WiFi, some see no differences. Would be interesting to see what the magnitude of that problem is.
My WiFi performance is increased by at least one bar, but battery life is decreased to 6h screentime...
My battery drain is massive after the .21 update, and 100% down to the Wifi (in battery stats)
They have obviously turned up the power but i cant say as ive noticed a massive difference with performance.
Yesterday i lost nearly 20% battery in the space of 30 - 45 mins.
I mentioned it in another thread. Support told me that there is an update on its way. Whether it will solve this issue or not, he couldn't say.
Yes, Gary updated one of his other threads, we have an update literally just around the corner. Also we may actually gain use of nvflash!
Anyway, back on topic, yes I've seen some increase in battery consumption, but I don't think it's as bad as some of y'all. I can leave my WiFi on 24/7 and still use my tablet for at least 3 days.

What makes you say we may gain NVFlash access ?
Had my prime hooked to my TV going through tobuscus's videos on youtube while I was gaming yesterday. Went from 100% to about 30% after ~5 hours. Not bad especially streaming 720 videos
Sent from my ADR6300 using xda premium
There definitely is increase in battery drain since .21
To say it's the wifi, i dunno...
Yes. the wifi, according to the stats, is the biggest battery drain, but seeing as we haven't had these battery stats previously, we can't really make a comparison on that.
For me i don't see much difference between wifi on or off.

4/27/2012 Update -
We are still validating a new firmware release. We are also tracking user reported issues with Tegra 3 games, WiFi Direct and some continued random reboot/lock problems with a few units. Based on current regression testing at HQ, NVIDIA and Google it appears we will need to sway out a few units to pinpoint exact user problems. For the unlocked audience, we have requested a version of NVFlash that works properly for users who unlocked their units.

From Gary himself.
Wifi was definitely affecting me. Bat life was dropping really fast. I now have wifi off when on sleep and the battery literally lasts forever. Been playing road warrior for a couple of hours each night some web browsing and you tube playback oh and messing with the ui. I still have 71% battery after 3 nights. Dock not even plugged in. Drops maybe 1% over an 8 hour night if that now. Was about 10% with wifi on.
Oh and when using its in performance mode, switch to power save before sleep.

First thing I noticed after the .21 update was the battery drain not an improved wifi signal. Factory reset mine. Same deal, now I just keep it in the dock while I'm out on the road.
I actually see fastest battery drain using the dock. NvFlash would definitely influence me to unlock my tab but def not before I know it works for most bricks.
I'm on a .21 ROM and my battery life is awful. I lose about 30% overnight while it's sleeping.

that's crazy..lol i may lose 2% overnight and i leave wifi on 24/7. im also on latest .21 firmware.
you have something else going on in the background to drain that much. i never heard of such battery loss while a device is only sleeping overnight. You better get the app here in xda called "better battery stats" to see what's really draining your battery. seriously doubt its wifi alone doing that.

I have "better battery stats" and it clearly shows that most of the drain is due to WiFi. There is a handful wifi processes which draw power.
I also recognised something else. Over the weekand I stayed with a friend. The battery drain on Wifi was back to normal over the weekend. Back at home WiFi sucks battery again.
I assume the Prime-Router type must have something to do with it.
I have a WRT350N at home.

Batterydrain and charging issue!!
I'm also one of those whose had a flawless Prime until the .21 update.
After the update I almost immediately experienced one "Sleep of Death"
that a soft reset fixed and that has actually not occured again.
Two other things are killing me though, after the update and the "SoD"-
incident I have terrible battery time and the tablet will only charge via
the keyboard-dock. If I insert the charging-cable to the prime itselves
it recognizes the cable and the charge indicator lights up red but I don't
get the lightning symbol on the battery status and in settings it says it
is not charging. If I put it to sleep for a while and wake it up again I get
the lightning in the battery icon and it says charging in settings, but it
charges so slowly I recon it would take 3 days to charge to 100%
I have RMA'd it one time but the useless guys who had it for 14 days just
changed the USB-cable and said it was A-OK, still nothing had changed.
Don't want to send it back in, tips and tricks would be much appreciated.
Thanks

that doesnt show anything. Wifi and display will always be the biggest battery drainers. plus the battery reporting inside prime is flawed. you need an app like better battery stats to show you whats really going on. my prime shows the same thing, as wifi being biggest drainer but i still get great battery life. from what you reported earlier, something else is going on in your prime you not aware of to lose 30% overnight with prime just sleeping.
I think I was one of the first to notice & question the battery drain after .21 update. Mine isn't as excessive as some are reporting, but it is definitely noticeable.
For example, before the .21 update... during sleep/overnight.. with WIFI never turned off, I will see perhaps 2% decrease in battery at most.
However, with .21 update... during sleep/overnight, Prime will lose about 8 to 10% in battery %. So, it is about 6 to 8% hike in battery drain during "sleep" stage.
I haven't tested or examined the battery life difference when it is being used.. as that's a bit more difficult to gather data based on my use...

i think you was. Its so hard to gauge and compare everyone's battery usage. Everyone has different settings used and different usage. I heard one rumor of Asus possibly increasing the wifi power for better connection/range. It was never confirmed nor denied. I never mentioned this issue before. I can try to dig up info on it from Gary and see what i find out. We have an update due to come out any moment now so we all need to see how battery performance is after that. I'll see what i can find out. Asus has been having trouble recreating the issues alot have reported. which makes it hard for them to fix if all their units they test never show the symptoms. For other software related issues, more logcats may need to be done and sent to asus. for ex. they haven't really been able to recreate the games crashing/freezing issue. Same with wfi direct. all their test units seem to work fine...lmfao new update is supposed to address some of these issues and more.

Eh, really? Wifi direct is completely worthless/useless to me atm (as in, doesn't work).... and to those who actually got it to work (based on their comment), it seems half-assed integration. Wish I have one of their Test Unit... seems/sounds perfectly functional (void of any of the issues/problems....).
Btw, don't take offense to this... but I have to ask...
1. Are you the unofficial spokesperson for Asus now? It still amazes me how they continue to respond to you & yet, I keep reading those with "issues" are yet to be contacted.
2. Did you have the authority to release/leak GPS dongle information? Such as leaking the photo a day before to Land of Droid for your 15 min. of fame.
Before i start explaining the situation, I have (you can guess by title) Samsung Galaxy S4 GT i9505 model... If i tell you ROM/Kernel/Baseband, Ill lie to you because i changed A LOT of ROMs/Kernels since i got this phone.
The problems is there, no matter which ROM/Kernel/Baseband i try, i get battery drain like 3% in 2mins... and guess what, I tried everything...
First of all im not so heavy user and I have only few apps installed, like Viber/Chrome/Es file explorer pro/Guitar tuna/Adobe Acrobat and thats all....
There were times when I had more than 25-30 apps, and i tho thats the problem but NAAAAAH its not!
I turned off every battery eating thing in settings (wifi scan, 3g/4g/ location, brightness, anoying sounds, and so on)
I changed my battery aswell, still the same, new one working just like the old one...
Included greenify/amplify/GSAM Battery Monitor/Build.prop scripts but no...
Stweaks, undervolt, still the same, bad performance still bad battery life...
I can't pass 2h 15mins SOT and there is no way to get more...
When I see people getting more than 3h 30mins i cry lol
Did anybody from XDA community ever have the same problem like me, and what to do? (except buy a new phone, forget about that I can't afford it)
IMEI of s4 is 05 which is not bad quality...
Appreciate every reply or PM, thanks!
EDIT: I forgot to mention that when i boot in recovery, wipe everything and so on, it takes like 2up to 3mins, the percentage is cool, i tried to be in recovery like more than 7mins and only 1% lost even with high brightness
Bump!

A galaxy s4 is around 4 years old... Batteries degrade over time. Luckily you have a Galaxy s4 where the battery can be replaced. My s6 can hardly last 2 hours as well, but that battery is not replaceable, so I bought a charging case.

Any other solution, help? Please?

Instead of trying to fix it blind, figure out what is eating up your power, install better battery stats (u can find it on xda) and wakelock detector, let them run a day and then check the stats, find the problem first, then you can deal with fixing it. I still have a note 2 (best phone ever made imo, which I but around December 2012) along with my other devices and i get 0.8% per hour, it has constant wifi on even though I don't use it much, and I usually get a few call on it a day.

I am sure i don't have any battery eating app from playstore, and like i said, i don't have many apps installed... As far as i can see, the main problem is when screen is on, while phone is idle, its not bad at all and used guard to disable keep awake, run in backround, start at boot for almost all apps..
BBs and Wakelock Detector said that the main drain are kernel wakelocks are ... ill post you screenshoots..

Are you using TW based rom or aosp rom? Do you have ambient display on or something like that? Or touch to wake? Or any apps or option resembling samsung AOD? Because the power manager wakelocks and services are most likely due to your screen being on, which of course will drain battery. And the wifi related wakelocks can be reduced with an app called leandroid which you can find on the playstore, to get the best out of it you have to unlock the app through in app purchase, but it works wonders. Another great app in nap time, with will force your phone into doze mode in around 5 seconds after screen off. Also there is hebf, a great app to optimize your device and manage power. But in the end if you have your screen on most of the time then no matter what you do it will consume a significant amount of power, only thing that can help in that case is lowering your brightness but I don't think there are any other solutions to screen on battery drain.

I have aosp rom, i disabled everything related to display, and even brightness is at lowest possible point, when i use the phone, and thats mostly at home, on weekends, I like before sleep to read news and so on, thats like 15mins and i lose like 25% and im sure thats not normal...
No i don't have any AOD display, when i turn off the screen, its cool, like 1-2% per hour, but the main problem is when the screen is on... and how the hell one day i have SOT 2h and 15mins, the other day i can't even pass 1h 45mins... with same setup, nothing changed, nothing specially turned on.... same usage, and no big difference in calltime, messages, etc.... wifi is turned off when screen is off aswell...
Stats are like for example 2h SOT , idle 8h.... and im sure there is a way i can get more SOT since the drainage when the screen is on, is crazy....

Quite puzzling, ok my last advice to you is to try HEBF, it has some battery profiles and performance profiles, also you can control cpu clock speed, kernel io and profiles, check to see if altering them helps you out, but other than that I am out of ideas. But when the screen is on kernel settings such as cpu speed, profiles and all that have major impacts on a device, so these are your best bet.

I set hebf on battery profile yet it heats my phone and burns battery even faster.... i tried stweaks, lowered voltage for 3 steps, phone is stable, but it doesnt change a lot... still huge battery drainage when screen is on... Im even using amoled photo.... But, when i boot in safe mode screen on time is great.... lel... im on lineage nougat ...
I have an LG G6 and a V30 on the Verizon network. On both, phone idle is using most of the battery. I've read several posts and searched the net without finding a solution.
I use a Samsung Gear S3 watch. Not sure if that could be the culprit.
When I Googled it, seemed like many others were also experiencing this problem. No one on this board is having this issue? Or has everyone figured out a solution? Thanks..
Why do you feel it is a problem? It doesn't matter unless your total battery life is not good to excellent.
Sounds like you just leave your phone Idle more than anything. I don't see a problem.
Sent from my LG-H932 using XDA Labs
check the battery usage ... find the offending app.
I am seeing the same: I don't use my phone very much, and not for gaming or video or anything very power consuming. So idle is by far the biggest battery drain on my V30 as well. The battery is still great on this phone, and it is quite frugal during use (as opposed to my beloved old Nexus 5, which was frugal when idle, but every touch of the screen would deplete the battery): I only charge the V30 every other night, and usually get 4-5 hours SOT on a full charge.
Battery stats attached. I have disabled most Google features (location reporting, always listen etc) but as you can see, Android Kernel and Android System remain by far the biggest app suckers. Lots of LG services buried in those. Some day I'll try and figure out which ones are the main culprits.

Either this is a bug from software or this is the way the phone display itself..
As long as it doesn't effect the battery usage, it's not a problem imo
The high idle drain is real, at least on my phone. It is NOT merely an error in how usage is displayed. If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.
This is fact, not opinion. Of course it could be unique to my phone and the OP's, although a few other threads mention high idle drain as well.
As I wrote in my last post, the phone has a good battery AND a frugal display, which means it's not a problem for most. Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.
@mankind_18: I am glad to hear that this is not a problem for you.

I'm actually seeing the opposite on my phone. Idle battery drain is minimal, but I feel like it drains a bit faster than others while in use. I did disable a lot of carrier/LG bloat I'm sure it's helped with idle battery usage to a degree.

Thank you for sharing this. Good to hear that your idle drain is low after disabling LG/carrier bloat. Makes me hope that if I take the time to go through it on mine, I may see improvement. So far I uninstalled a couple of LG apps through the Settings/Apps menu, that's all. I've meant to do more with ADB, just haven't had the time yet. Your post is encouraging in this regard.
But puzzling that you find active drain so high. My old Nexus 5 was like you describe: Very low idle drain (lean custom ROM and not many Google apps installed), but drained fast whenever I used it. As described, the V30 surprised me by doing the opposite. Hmmm....

Well it's not excessive relative to other phones I've used, just seems higher than other people based on their battery usage screens posted.

I think it's kind a normal to find idle taking up most battery if you're not using the device (i mean less), because when i compare it to a9 pro, it's the same actually.. when i use it often, screen will take the most battery percentage.. but if i use it less, device idle will be the most at the top..

If the phone is flat in 3 days, then your idle drain rate is 1.25%/h. That's elevated.
It should be possible to improve depending on what the causes are. Could be apps, could be apps you need and then there is the network.
As a simple test, charge up your phone before you go to bed. Then leave it there, untouched with AOD off.
In the morning, settings - battery - battery usage - estimated time remaining <-- how much is that ?
Your battery will have to drop to at least 98% before that info is available which in your case could be sooner than morning maybe in a couple of hours

True. After two days you've lost half the battery. Ideally it should be less than that.

Do you have access to a PC with adb installed ?

Thank you for the response. That was posted over a month ago, and I finally did get around to disabling (or rather, uninstalling with ADB) a bunch of LG apps and services. Also some T-Mobile apps after switching to AT&T MVNO. That helped a lot, and I am now down to approx 0.5%/hour idle drain. That's overnight, mind you, and I still find it somewhat high considering AOD, Location, Bluetooth, NFC are all off, and the phone is completely still for 8-9 hours.
But I can now generally recharge only every three days, and still get 6-7 hours SOT. I guess that is great for any phone. Sometimes and I have to use Battery Saver to make it that far. It helps a lot to reduce battery drain, both during idle and use, and has no noticeable effect on usability.
Also on the positive side, I haven't had any of the lag issues mentioned by others in various threads after disabling apps. In fact, it is even smoother than before disabling them. I did go a bit too far, as I lost the ability to Google Cast the screen -- strangely, as I didn't touch Google apps or services. Also, I lost LG SmartSettings, which I didn't actually use, but didn't mean to lose either. I kept the SmartSetting app, but apparently one of the LG task related apps I disabled caused it to disappear from Settings. No other issues or functionality losses -- except the ones I wanted to lose.
So I am OK now -- though I still think idle drain is higher on this phone than it should be, even after disabling LG's duplicate and redundant services and turning off known battery draining features (AOD, Location etc).
Edit: Thanks again for your response and offer to help. Re-reading my post, I don't think I fully acknowledged that.

By adb i was referring to granting a one time permission to the better battery stats app. Will be a good next step if you've not used it yet since you've done a cleanup already.
The dump file will reveal what your phone is up to when you set it down and whether further improvements can be had if feasible.

How did you measure that rate ? wonder if its possible to reduce it further. Up to you

6-7h/SOT is normal for the v30, on wifi or bands 12 & 20 with heavy use.

If you're interested in exploring further with BBS, let me know. It has a strict procedure to follow which i can walk you through

I did grant usage stats permission to GSAM. Otherwise it wouldn't have shown the details in those screenshots.

GSAM can show stats for various time periods, including custom ones. I generally check it in the morning after it's been lying on my desk or nightstand overnight for 8-9 hours. That's the ultimate Deep Sleep condition.
MY cell radio uses a bit more after switching to AT&T and returning the signal booster that T-Mobile provided me. The booster didn't improve T-Mo weak's reception in my apartment, but it DID provide a stronger signal to the phone, so it doesn't have to work so hard to maintain it.

I'll take you up on that. I haven't used BBS in years (different phone) so not up-to-date on it at all. I'll follow your procedure, just tell me what to do.
Thanks again. Much appreciate your help!
Edit: I downloaded and installed BBS 2.2.2.0. Holy crab, I can't believe that thread is now 3300+ pages!

Good, this will allow you to compare both tools and see which one is more useful.
Now you need to give BBS the permission in ADB as shown here
adb shell
pm grant com.asksven.betterbatterystats_xdaedition android.permission.BATTERY_STATS/
That's it. Switch off Developer options.
Then go into BBS-Settings-Advanced- (scroll to the bottom and click System App) and verify it says BATTERY_STATS granted. Cannot proceed further otherwise.
If ok, back out of advanced and tap 'Watchdog' then enable
Next, try a dry run. AOD off. Let the cell be on since that's how you use it and wifi.
What battery level is when you start the idle test matters. Can be anywhere between 50 to 95 but not over or under. More consistent data between those two points.
Let it rest for an hour. Do not touch it during this time. if the phone rings and you answer it then your log is going to get polluted with irrelevant info. It's useless, have to redo the idle test. The not touching it matters a lot.
When time is up, in the app under summary there are a couple of dropdown menus. Select 'Screen Off' instead of 'Boot' for the left and the menu next to it, select 'Screen On' instead of Current. Telling it to print data only during the time screen last switched off and turned back on. Very handy. As you can use your phone before the test and when ready to do the test it doesn't matter where you start within the limits mentioned. Screen off to screen on, That's what watchdog does.
After that, Look for the share button at top and select Dumpfile then Save. The txt file will be saved in emulated/0 so in LG's file manager, Internal storage, scroll down, it should be there by default. file name betterbatterystats- date-time.txt
Post that txt file as an attachment in your next post. Hopefully, on the V30, BBS will record under the sections, partial wakelocks, alarms, network which are required to understand where wakes are coming from. If this part is successful then you can go on to do a real idle test.
There are three key points here,
- idle test done when battery between 50 - 95
- your screen on during the idle test cannot exceed 1 minute. No touching
- getting the correct start and end points meaning you selected screen off to screen on to record in the dump.
Get this down right and you will be ready to do a real idle, test. There is one extra condition now. Test cannot be less than six hours. Can certainly be longer but not less than 6h. This is where the no touch rule starts to grate but that is the minimum time required for any wake locks to make themselves known. Getting the procedure right means you don't waste runs. And you will be doing several as you hone things
A bit rigourous but this is what the creator of BBS and the guys in that 3k+ thread insist you do to get the most out of BBS. They won't look at your dump file otherwise. Redo it they will say

Thank you. I'd already granted it permissions (BATTERY_STATS and DUMP). But I cannot install it as System app, since I am not rooted -- which it promptly tells me if I try. I was looking for somewhere to confirm the permission, but didn't find it.
Anyways, I started the Watchdog. I'll be charging it overnight, then do the dry run tomorrow after the battery has dropped below 95%.
Thanks again. This will be interesting!

Ah, i wasn't clear, install as a system app isn't required, that screen is just to check if the permissions took.
A popup appears saying root is required and disappears after a second or two, if you see the word 'granted' then you're good to go. Fingers crossed the right sections get data
