Anybody else notice that standby battery life seems to have gotten worse in 8.8.3.33? Mine was dropping less than .5% per hour before, now it seems to be considerably more (just noticed so no chance yet to quantify)...
Edit: Actually, I'm leaning toward battery life in general being worse...

Hard to say but I'm leaning towards maybe lol
I agree it could be a maybe.
Mine was fully charged when I disconnected it before work. It's been sitting at home on standby for 15.5 hours and it's at 94%.
During that time it's been connected to my WIFI, it updated google translate, and it synced with 3 e-mail accounts every 4 hours and my main email account every hour.
Seems the same to me.
mines seem to get even better battery life after update. check your background processes to make sure they aren't any unwanted background apps running. those will drain battery. overall battery life is great and the standby life is unreal how good it is. do you think your battery fully broken in yet? how long you had it?
Mine seems worse as well. No testing to prove it but it's been in the back of my mind since shortly after the update.

Nothing new since the update as far as background processes. I've had it since Friday, and it's had two full charge/discharge cycles. But again this is compared to before the update...
I'll let it sit overnight and see if this is just my imagination.

Mine goes down 15% per hour - mainly browsing www. isnt it to much? Before and after uptdate
i had 99% a hour ago and now its 90% i have only watched 10minutes of iplayer and read one email the rest of the time the tablet has been on stand by. i have a task killer running and it was up dated yesterday.
also i cant seem to see Time remaining of the battery rather than just %
its as bad as my HTC HD before it was rooted
As an update, I let it sit overnight for 8 hours and it went from 15% to 12%, or about .375%/hour. So, that's pretty good standby performance and my impression was mistaken.
After using it, though, I'm thinking my impression was coming more from battery life in use, which does seem less than before. I think they've done something with the power settings that I'd expect them to undo in the next update (or just in the ICS upgrade).
The power mode you using, type of activities you doing on prime, and brightness will directly affect battery drain while device being used. I always have my prime in balanced mode for the best of both worlds, Performance and battery life. as i never had any lag or any anything in this mode. I've noticed, even with heavy usage in balanced mode, battery drains about 10% or a lil less per hour. if light usage then it even drains less. Check out my "Different Performance Modes of Prime/Tegra3" thread. I started it to address issues like this and people compare performance and battery life in different modes. as everyone will have a different setup or use different. There is also a bstterylife thread started by TylerZ that needs resurrecting also. now that all the preorder threads n such got merged we can have some more relevant threads stay current.
honestly though, the battery life is amazing on this tab. to the other guy saying he has a task killer rubbing in the background..lmao that's his problem right there. Honeycomb or ICS doesn't need task killers as memory managemanent is already taken care of by the OS itself. and does a pretty damn good job at it also. if you wanna kill one or 2 apps that's OK. but to have a task killer running in background of honey comb OS does more harm than good.

i've noticed a slight downgrade in battery life while using the tablet, but not in standby mode.
also noticed that changing the performance mode no longer seems to make as big of an adjustment to the screen as it used to. perhaps the update increased processor performance, which explains why it feels snappier in general, and also seems to use up slightly more power.

Well, this question is for my lucky friends who have their new toys
Battery life is so good?
Post your test here!
Don't have screens for ya but battery life is more than adequate. My gf and I used it for about 5 hrs last night and it dropped to about 45%
(Games, xda, Netflix, and just tinkering around)
I'm curious what kind of battery life you folks are seeing, now that you all have had time to get some real world experience with the NT.
Thanks!
10 hours of continuous usage with 25% brightness.

Yea, the battery life and responsiveness of the device is definitely top notch.
I'm pissed as hell the bootloader is locked, but this device is an absolute steal for $250 bucks. Especially if you can manage to discount that price down.
Extremely responsive and awesome battery life considering I'm running max brightness and wifi 24/7.
I'm always surprised when I'm done using the Nook that it was still running. Granted, I ran it until it had only had around 20% left. But hey, if your sitting in one spot using your nook for more than ten hours, then you need to find something else to do. ^_^

Good book, nice day, under a tree? Done that many times just reading off my PDA.
Thanks for the feedback!
The battery life is definitely adequate.
I can usually go 2 day without charging thus far. I keep brightness at ~20% or so (I can't stand brighter, it actually bothers my eyes).
I also use multi-picture-live-wallpaper and it doesn't seem to drain my battery at all.
I do some pretty heavy use of it as I am reading on it and studying for med school for probably ~6 hours at a time
Battery life is great. BN's numbers seem dead on.
Lasted the flight from San Francisco to Sydney
I'm getting around 10 or so hours of use at 2/3 brightness. Battery life is amazing on this. I charged it last night. Took it off the charger at 10am didn't touch it till 10pm tonight. It was at 99 percent then. I think it turns off wifi when it's sleeping.

Yeah, it definitely turns wifi off on its own when sleeping
Yeah Ill echo the comments here, battery life is absolutely superb and the responsiveness of the unit for the price is fantastic. Sadly its a case of if only B&N....to fully realize what the tablet would be capable of.
I have to agree that battery life is amazing on this thing.
I've got wifi turned off full time (to avoid updates from B&N) and the battery just seems to last forever. Granted you always use less battery when you're not going online, but still, it seems to really really last.
Frankly it's making my phone quite jealous.
Umm, my nt's battery isn't as impressive as i hoped. I use 25% brightness, wifi on, no fancy live wallpaper. I noticed for every few minutes of sjurfing, battery would drop a percentage or so. For usage of about 3hr withoit wifi, i would use up about 40 %.
Anything i could do to tune it up a bit? I do noticed amazon appstore is always running, so is clock, contact, tb, and my yahoo mail app. Any help is appreciated.

That sounds about what I'm getting and I'm wondering whether it's defective or not (still within return window).
edit: Probably normal - ran into some threads on B&N's boards where other people are averaging 5-7 hours. If I idle / read, I get about 1% every 8-10minutes or so so B&N's time estimates were definitely not "video," "browsing" or "games." Wifi on, installing or rebooting a few times, it drops to 5-6 hours tops between 100% and close to 0%.
My phone gets -way- more time, even reading.
the battery on this is great one of the biggest things going for it. better than my phone for sure.
For you guys with bad battery life, you might want to try better battery stats. Then check for partial wakelocks. That's usually the culprit on my phone. It seems weird some of you are getting half the battery life of the rest of us. Personally I haven't even turned wifi off at all, and also haven't turned my brightness below half.
It's in the google market, it won't show up on the nook. I downloaded it on my phone then used the app share my applications then back up to sd. Upload to dropbox. Then download it with dropbox on your nook.

I looked at this (and other battery programs), but wasn't sure what they did. Now I sort of do. I'll check it out! Wifi on definitely uses up at least 20-25%ish extra battery, and I *have* been moving a ton of stuff to/from sd cards and uninstalling and rebooting a lot, but the above did seem very short. Too bad there isn't a battery hardware test
Failing those applications it may be worth doing a full reset; Especially since most other owners are reporting MUCH better results.
Before I start nuking things around, I used BetterBatteryStats, check for partial wakelocks, and the highest % is from ActivityManager-Launch, which occupies 0.3% or 5minutes or so since I fully charged it.
Also, i noticed "Wifi Locked" is extremely high, like 89%, whereas wifi On is only 26%. What does that mean?
I'm not fully versed in how Android handles power management. So what should i be looking out for? Thanks!
Hey guys i tried looking through for a bit and didnt find much on this...how is your TFP`s battery life? I`M not too happy to be honest, for instance today my battery is at 20% been on for 6 1/2 hours and havnt really done anything too intensive, mostly just web browsing and downloading apps, played a game for about 5 minutes. My touchpad seemed to get similar if not better battery life... anyone notice this too?

It really depends on your setting, or how you use it... but saying that..
it isn't as "good" as Asus advertised, nor some other media/blogs have reported from their "hurried" interviews.
ICS update probably has something to do as well... I really don't think Asus and Nvidia has fully worked out Tegra 3 with ICS yet.
I think in normal use the processor is kept at too high a frequency. I rebooted about an hour ago, and since then mine has spent well over half the time at 1200MHz. Given what I've been doing, that seems like overkill. I think ASUS is still tweaking the power profiles, which might account for the apparent variation between revisions.

I've been satisfied with battery life, not that I've timed it.
Sent from my Transformer Prime TF201 using Tapatalk
I've timed it several times. Its your settings. I get longer than what you posted on my 1.6Ghz vipercontrol overclock. Stock settings easily get 9 or more hours. I always have my brightness low as its bright enough. Having it at 50% or more is a waste unless you outside LR have bad vision. At night I know you can't be having brightness up like that or you'll hurt your eyes looking St that bright screen. DISPLAY BRIGHTNESS is the biggest drainer of battery. Along with web surfing, watching flash videos, or streaming movies. If you doing all that, maybe use power savings mode instead. You can still surf web n all that with no problems plus battery will last even longer.
For me, my prime easily gets Asus advertised battery life n more sometimes. If I can run a 1.6Ghz overclock n get better than what y'all posted then you need to adjust your settings.
As with all battery life situations on Android, make sure you pay attention to the following:
Screen timeout, make sure the screen does not stay on for long when you are not using the device.
Look at your applications that schedule background tasks and auto synchronizations as well as the sync settings in your Accounts & Sync. Don't sync data that does not need to be sync'ed.
Use the balanced performance mode most of the time.
Turn off features that you do not need, such as GPS or bluetooth, if you are not using them.
Under developer options turn off 'animation scale' settings. This will make moving around menus more snappy since there's no transition time and it also saves a little bit processing power if you move around in Android menus a lot.
If you do not use WiFi, keep it off or at least turn off available network notifications so it would not constantly search for them.

On ICS it should be done by GPU, so I think it will affect battery life very, very little.
My concern is more about the keyboard/dock battery life.
It seems to drain a lot faster than the tablet and it never stays long at 100% ; always fall to 99 or 98% although the tablet is not under 90% yet.
I wonder if this is because I first charged the dock alone instead of charging it with the tablet on it.
Anybody sharing these feelings with me ?
I would say the reason is that dock always charges the tablet. I've also notified that dock's battery is empty in the morning if I left tablet and dock together during a night.

Please use search, the 98%-99% thing has been discussed and asked over and over again for ages. Your battery never stays at 100%, neither the tablet or the dock.
Once battery reaches 100%, it stops being charged, otherwise it can damage the battery.
Dock battery discharges quicker because the dock battery is smaller than the tablet battery. The dock does not 'double' the battery life.
As of TF201 (differently from original TF101), dock starts charging the tablet once tablet falls near 70%. This makes sure that battery on the tablet (and dock) are used more efficiently and lasts longer (it goes through less cycles in the end). While this means that dock does not keep tablet at 100% all the time (so you can remove the tablet at 100% always), it does mean that battery life will not diminish as quick as before and you're prone to less hardware problems in battery in the long run.

The 50% brightness is most likely why you are seeing lower than expected battery life. Also, you should be in power saving mode if you are wanting to extend the battery as long as possible.
ASUS claims the Prime's battery lasts 12 hours using the following criteria: "Battery life tested under power saving mode, playing 720p video playback, Brightness:60nits, default volume with headphones."
http://usa.asus.com/Eee/Eee_Pad/Eee_Pad_Transformer_Prime_TF201/#specifications
Not sure what 60nits corresponds to on the brightness selector but I am assuming it is low.

Yeah , 60 nits is very low, especially since prime Max brightness is significantly way higher than that. Like 380 nits(unit of measurement for brightness) or more. BRIGHTEST tablet/display on the market today.
After posting last night I messed with YouTube and browsed for about an hour and only lost about 5% or so. Seems good to me.

I've noticed on both the Prime and my original Transformer that the dock battery does seem to discharge more quickly than expected when charging the Prime. It's not directly proportionate, I don't think, i.e., 22Wh is about 10% less than 25Wh, but I don't think the dock only discharges 10% faster when charging the Prime.
I think there's something about the charging process that makes it less efficient than simply powering the unit. Perhaps some power experts can chime in here and explain it... Certainly, I've noticed that charging the Prime from 70% to 100% can just about completely discharge the dock.
I've noticed the dock discharging faster if it's plugged into my usb port in my PC. I think the media mount takes more power than I thought it would.
When not connected to my PC through usb, the battery life is pretty long when doing regular web browsing and video watching.
Playing games obviously causes the battery to drain faster. Also the brightness also has a large affect on my overall battery life.
As others have said, turning off wifi when you're not using it will massively extend the battery life.
So I started a new thread cos its kind of different to my other one. The last little niggle with my Prime seems to be the battery. I read the instructions for once and it said to charge it all up. So i charged it till it was green and then powered it up for the first time. So as the instructions say i need to break the battery in. At the moment i am getting about 5-6 hours. The pad is on balanced with auto brightness. Does this seem normal for new battery. I would hope to end up with 9-10 or are my expeditions too high?
From what I remember the instructions stated that for the first time you should leave the prime charging for 6 to 8 hours. I personally didn't follow this and I'm still getting pretty good battery life. My advice is to let the battery drain out and charge it to full again and leave it connected for at least a couple of hours. The battery should calibrate itself through a couple of charge/discharge cycles and get better over time. Forgot to add, I have my wifi set to turn off when screen goes off.
If you're on firmware .21 it may be due to wifi. Check your battery stats. I have great battery life but as soon as i turn wifi on and use it battery goes down waaay fast.
I hope the new firmware thats coming adresses that, because before .21 that wasnt the case.

People that didn't fully charge it up the first time for 6-8 hours, exactly what kind of life are you getting and could you please explain what things you are doing on it. I didn't charge it fully and it accidentally got turned on during its first charge.
Thanks,
If you are on .21 don't expect the battery to be near 8hrs while on wi-fi surfing/video/screen on/etc. I had it on .15 for 2-3 days while deciding if I wanted to root or not and it was near 8hrs wi-fi on. I'm also hoping for the next update to fix whatever they implemented in .21 that's causing a significant amount of drain.
I am on 4.0.3, is that the right one
Sorry, wi-fi is .22
Thr charging over night for 10 hours or whatever is nowadays just a Myth that came from the old NiCd batteries (It was true back in the day), new LiPo / NiMh batteries have no Memory Effect and the first charge is nowhere near as important as with old ones.
In fact is actually better not to stress the battery doing full discharges / charges cycles.
These batteries get to their full capacity after about 10 charging cycles.
So if you didnt not charge X hours for the first time, dont worry, yout battery ill work fine.
The only thing that should be pointed out is that if you use very often your battery, every 2 - 3 months is recommended to let the battery discharge to 0% and charge while off to 100%. If you dont use the battery often (always connected) then is better once every month. Thats to keep the internal chip from the battery calibrated.
Well atm i am draining it down to <10% then charging. Is it ok for these modern batteries to be left on charging past 100%?
Battery life still seems pretty poor after 3 0-100 ish charges. 1-2% seems to last less than 5 minutes when on the net on balanced mode and screen brightness mostly down.

Yes, once the batteries are at 100% they stop charging. You can have them 100000 hours connected.. and they wont go past 100%.
im on .21 and i get great battery life. i never cut my wifi off. its on 24/7. battery drainage will more so be dependent on display brightness and what you are doing. wifi is already a known, wifi on any device drains battery at a faster rate than wifi off. it takes power to make wifi work ya know..lol i can easily get 9-10hrs. + with my brightness set to less than 25% & wifi on all the time.
also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

here are some battery saving tips!

That's what I'm saying. Everyone web browsing and gaming is different. Some web pages people visit might be loaded with flash content vs. Someone who visits a site with less flash content. The one with the loaded flash content will drain or use more battery than the other one. Same with gaming. I might like to play Dead Space or Shadowgun and you like to play hang man or some other simple game. The battery will drain faster with me playing the 3d graphic intensive games vs. The person who is playing simple or less graphical intense games.
Wifi is a must have and no way around that if you want to web surf. The amount of screen brightness, 3D gaming, and web surfing will influence how fast your battery drains. Wifi drains battery but not at a faster rate than those other things listed.
I think some people here expect to have brightness up to the Max with super ips+ on, gaming and web surfing all day and expect to get 10+ hours out of it. Lol. Its not happening. There are easily things you can check for and change to make you have better battery life. -
-First one being not to use auto brightness and don't have brightness higher than 25%. That's if you so concerned about making the battery last long.
-Second thing you can do is go into settings and change screen off display settings. I have mines set to 30 or even 15 secs. That means once 15 secs. Or 30 secs. Pass and I haven't touched the screen, the screen will cut off. That's a huge battery saver right there. Because my screen isn't on as long when its not in use.
-Third would be to go into settings and lower the frequency of sync settings. I don't need my email syncing every 5mins. Or my Facebook syncing every 5 mins or etc.. cut them down to maybe every hrs, or every 12 hours, or once a day. The best would be to sync when you open up the app instead of it doing it automatically in the background. Completely cut off sync to apps you never use. Constantly having things sync in the background is a major battery drainer when the screen is on or even while device is sleeping. If you put device to sleep and its always waking up to sync data, don't be surprised if battery drains at a faster rate during sleep or when device is awake.
-Fourth, cut of unneccessary sounds. Do you really need the keyboard or screen presses to make a sound when you press it? If so, don't be surprised your battery draining faster.
-Fifth, cut off that stupid vibration motor. Do you really need your tablet to vibrate when ever you press something on the screen or keyboard? Do you really need it to vibrate when your gaming? If so, don't be surprised your battery is draining faster then. Because everytime that vibrate motor goes off, it drains battery.
SIXTH, you can go into settings and have wifi cut off when device is asleep. Or you can go into Asus customized settings and have it cut off network activities when the screen is off or device is asleep.
All very easy steps people can take. Same thing as in saving gas in a car. There's things you can do or not do to make it last longer.

It does seem to be getting better though. I have had it on for over a day now and it is at 50%. Probably had a good 3ish hours of actual use. During the breaking in of the battery stage is it better to let it drain then fully charge or charge whenever I can?

also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

Well hopefully after a few charges I will make my way unto that region, I think it has climbed though to a closer to 6-6.5.

I'm still on HC 3.2.1r2 but my Tablet's battery life is quite good and excellent on standby, but I've never tried to go past about 4 days. Do you use any "battery-saving" apps or things like WiFi lock apps that might cause wakelocks?
i have a 3g version and the battery lasts longer if i switch the device to airplane-mode...every 3-4h 1% battery

Agree, Since my ICS upgrade the battery has flattened out after just a day or two. This never happened before the upgrade. I've had it since it was released..
Haven't had any time to investigate whats causing it yet, will try to find out on this cycle.
Even with ICS my tablet holds 4 days with moderate use. I mostly use it for the IR function, RDP to PC or just for browsing, so nothin that would really drain the battery.
I should mention that I removed all bloatware and I hit the "Kill All button" (widget from ZDBox) a few times a day.
This is just a personal choice, but I've never found battery saving apps very effective. Most will give you either equivalent or shorter battery life so they're rarely worth it.
Ironically, some of them will shorten the battery life since to do all their conserving activities, they have to get wakelocks and some of them don't release them or they get queued and it ruins your battery.
Yep, my battery life is also rubbish now I'm on ICS, it'll need charging after a day!
I have noticed that Android OS uses up about 20% of the battery, while on my One S it's only about 3%....
wow i am surprised by 4 days. even on honeycomb i didnt get more than 2 days. on ics it's even worse. i am not using any apps in the background besides google sync. i do have 3g version, without simcard. and my wifi discnnect policy is "use mobile data" (i thought since there is no sim, this will disconnect the wifi)
Wow, just got my G2 on Friday night, and yesterday I was sitting around the house on WiFi all day, playing with it, I got maybe 12 hours out of it, before it was down in the teens.
Last night I charged it fully, woke up, unplugged the phone 100% battery, now 2 hours later it's down to 89%, and all I did was surf XDA and some websites for maybe 20 minutes all on WiFi.
I need to root this thing, and install CleanROM, and debloat this beast, because with a 3,000mAh battery and Snapdragon 800, I expect way way better battery life.. I am looking for Note 2 battery life, that thing could go 36 hours without sneezing.
Is it the ton of bloatware on the phone from ATT + LG killing the battery ? I am shocked at how much bloat this phone has, it's over the top with bull**** apps I never want on here, pretty ridiculous.
If you had taken the 2 minutes it took for you to write up this rant and look for the battery thread you would have seen the G2 has amazing battery life. You are obviously doing something wrong.
Give it some time to settle before deciding anything. Mine actually took three-four days and some reboots before it calmed down, and now I have about twice the battery stamina compared to HTC One (which I threw in the dumpster btw) .
Could be hardware issues. I had my G2 for a week now, and I tell you what the battery is amazing. I can easily get 4-5 hours of screen on time with 24+ hours battery life, and that's with stock. all sync (fb, whatsapp, twitter) with a few tweaks. I am coming from Nexus 4 and very impressed because with G2 I literally have a double battery life.
And also G2 is very fast charging. Only take 2 hours to charge from 10 - 100%. That's amazing!
My battery is getting better every day. Yesterday I got 14 hours of use, 5 1/2 hours screen on time, and an estimated 2 1/2 hours to go at 15%. Definitely the best so far. With more tweaks, I'm wondering how much I can get today.

I had some bad battery life initially. I found the biggest culprit of battery drain in my case was CarrierIQ. After rooting the phone and disabling the CIQ, my battery life has been great. It goes 24+ hours easily and it seems it can run 40+ hours though I haven't tried it.

same thing happened to me. First few days it was great then battery sucked. Disabled the CIQ with system tuner and I get 2 days and 5 hours screen time and still usually have 30% left
The battery life is love and hate on this phone for me. The love part is the battery life on this phone is great. The hate part is you have to turn off a lot of things to get that great battery life.
I've never had to turn this many things off to get good battery life on any other phones that I've had. I have to completely turn off anything location related which is a big bummer for me. I always like to have a clock/weather widget on my home screen but it never updates with all of the stuff that I have to turn off.
It's one of the few reasons why I'm moving to a Note 3. But when you heavily tweak the system, you can get fantastic battery life out of this phone. Good luck!

if you only turn off the google apps location settings and keep the app location settings on you should still see good battery. I use the stock weather clock widget and it updates just fine with those settings

[OFF TOPIC]
yet another topic's title that would detract would be buyers.
This phone has the best battery life of any phone I have ever had, stock. Even better than the Note series. Clearly user error
Battery life issues are so variable between two use scenarios it's like comparing apples and oranges. As others have said, battery life is pretty damn amazing for this phone.
Post some results from GSam battery monitor or wake lock detector to help you sort it all out.
I am still running stock, not rooted or ROM'd yet. Right now I am at 8h 29m total usage off a 100% charge this morning. Current battery life is already down to 35%, and only 2h 49m On Screen Time, and I have been on WiFi all day. I have GPS off, sync off, no e-mail or Facebook stuff installed yet.
Might as well give you a fast screen shot of mine
People with great battery life vs those with poor. Do you think its mainly settings and a good ROM or root with bloat deleted ?
Or is it hardware related ? Bad phones from factory shipping with damaged batteries or hardware ?

Battery so poor, I might return my G2 for a Galaxy S4 instead, for the removable battery.
Just shocked I'm barely getting any better battery life than my Nexus 4, which got 4h On Screen time, and over all only 12 hours usage
Do I have a bad phone ? Or just stock is screwed up and I should factory reset, or better yet, root and install CleanROM ?
