Batterylife comparison: Stock VS CM9 VS CM10 - Galaxy S III Q&A, Help & Troubleshooting

Hi all
This is my first post, so let's hope I've gotten it right and am abiding by all the rules and the n00b video. And yes I did search for a good 10 minutes about batterylife and battery before posting and didn't find anything relevant.
I've recently swapped over from Apple iPhone and I'm now very much enjoying being on Android. However batterylife is a big concern for me, as on iPhone I could go 2-3 days without charging and now I can barely make it home from work and I definately have to plug it in before dinner. And yes this is with me closing down applications, wifi when not used, bluetooth when not used, running latest kies released PHONE:LFB firmware and so on.
So my question is... how is your batterylife after having rooted and installed a custom rom? The one I'm thinking mostly about using is definately the new Preview 3 (or perhaps wait for 4 or 5) of CM10, that XpLoDWilD is working on. Does anyone have any experience with the batterylife before and after?
Thanks a lot for any help you can provide! :highfive:

That's very weird. Are you international or a US S3? I easily get 3 days battery, very easily. Perhaps try turning off useless stuff like bluetooth, gps, wifi, etc when you're not using them. Turn off push email and other useless crap. See how it goes then?
I still have the stock ROM, usually 3.5 days battery before it gets to 10% and i charge. I'm going to go to OMEGA rom soon though.

I have tried almost all custom roms out there. And I can easily say the battery life is not any better if not worse on custom roms.
Stick with the stock rom. I would however recommend flashing a custom kernel like speedmod or phenomenal. They definitely give you that extra juice you need at the end of the day. The idle time and screen time has increased for me 10 to 20 % compared to stock.

I'm using the international version. I did turn off bluetooth and wifi, but not gps. Will try that aswell. I have manuel mail check every 1 hour, but will try to set it to 4 hours.
However from what I read in the reviews on GSMarena and other sites, it's quite normal to only get 1 day worth of battery.
Description of a pretty basic day with the Galaxy S3:
I usually unplug mine at 6 am, with wifi and bluetooth off and screen always on auto brigthness. Then at 7 am i turn on bluetooth for my earphones and bike to the train station and browse the web and such for about 45 minutes in the train. When I arrive at work it's usually around 80% battery and I turn off bluetooth. Then I'm at work from 8 am to 4 pm and check mails, texts, calendar and possibly make 1 or 2 short phone calls. At 4 pm I think the battery is often around 40-50%. Then again on the ride home I use the same, so it's usually around 20-30% when I come home. I then usually turn on wifi and play a couple of games, or watch some Netflix on it while I'm doing some other stuff or attach it to my stereo and play so music from Spotify on it. At 6-7 pm it's usually beeping at the 5, 10 or 15% marker for more power and wants me to plug it in to a power source. If I try to wait till I go to bed, I usually end up having it automatically shut down from lack of power.
I'm wondering if this seems normal or if perhaps my battery is faulty. From the review at GSMarena it seems quite normal and that's just the way Android is. They even gave it a good battery rating inspite of saying that it would only last them a day.

Okay, thank you for your reply

it all depends on the usage i have an iphone 4 as well and i have to charge it by the end of the day (at 10pm). So it dpends on what you do with your phone if you use 3g all the time thats not gonna last long if you have syncing on all the time and gps that wont help...if you just let it idle then you can get 3 days uptime with maybe 1 hour screen time.

My basic day is charge the phone at around 8pm, unplug at 10pm. I never charge overnight it's pointless (not that i think it'll hurt it). Wake up battery is usually around 95% after my alarm goes off. Brightness is about 60%. I don't browse the web very much, and I don't play many games, let's say 1 hour of web and 1 hour of games/videos/music per day. Maybe 1 hour of maps too. Mostly though, I text message and phone call.
I don't think yours is faulty, i think it's quite normal, it seems like you're a heavy user, I'm a light user. If I used my phone as heavily as you did i'd be happy with 1 day of battery.

One day of charge (the battery being at 20-40% at the end of the day depending on the usage) is quite normal.
I've found CM9 with Siyah to give the best standby battery (1-2% drain per hour with 3G and Sync enabled) since it's very lightweight and has no battery-draining bloatware other than what you install.
CM10 is still too new and unfinished to be battery-friendly, it's not that bad though.
However sometimes it will chew the battery for no freaking reason (at least I cannot found any) and the CM9/CM10 stock kernel is not that battery-friendly on active usage. No Siyah yet =(

No way is that good man, that means that if you leave it on standby alone you lose 25% per day. 0.5% per hour would be good/normal IMO.

[dev support please] CMOD 5.0.5.3+ display batrery killer.

I figured I'd make this its own thread after speaking with several people with the same problems using a CMOD 5.0.5.3+ rom. This wasn't a problem in lower editions from what I can remember in testing.
Idk but I believe it is something in the kernel affecting this problem with the display hogging my battery. Even after flashing an undervolted kernel I still can only last 24 hours with an extended life battery, vs a weeks time before. And the display problem has been like this in all CMODS test .6 Roms as well so idk if it is in the process of getting fixed or simply overlooked. And other Rome work well but are slower it seams.
The display settings doesn't matter auto or manual its about the same. So devs what can we do to find the change or what can I do to help?

I'm running test 3 of 5.0.6. Today i read a book with fbreader for around 2hrs on it whilst on the train, had 2 30 minute phone conversations, around 20 texts, a dozen gtalk messages, and played blackjack for about 20 mins. i'm also using pershoots OCUV kernal, and after 11hrs without being plugged in I am at 75% battery. I'm happy with that.
I think it is a work in progress, as each new build comes out it's better. His testing builds are just that - testing. None of his release builds I have ever had an issue with either, although maybe my phone ue is a lot less than others I dunno. All i can say is i've never been tempted with another rom since early days on my magic phone Cyanogen rocks!

Nope, I have it on auto-detect, so quite bright when on the train and outdoors. I have setCPU (market, paid) running and set battery profiles - although I haven't hit them yet. I have it set to max 1.1ghz 100% to 50%, 998mhz from 50% to 40%, 776mhz from 40% to 30%, and under 30% to 500 and something.
I do use an app called autostarts (market, paid) and have set everything but system services/apps to not run on any kind of state change or startup. I use Advanced Task Killer to kill apps as soon as I finish with them.
But i've had all these for ages, I just think a big improvement on the last release test 3
Nandroid your existing and try out test3.
I've been experiencing the same symptoms with my battery usage generally dominated by the display. I'm using a UV kernel currently (intersectravens) so we will see if the same happens.
KingKlicks's DESIRE rom doesnt have the same problem it seems and the battery usage is much better.
Wondering if there is a underlying issue.
after .6 test 3 the battery has improved decently, still the display is hogging battery life more so than in the sense rom
Same thing here... Display totally kills the battery with CM5.0.5.3 and OC/UV kernel. Phone rarely lasts over a day with moderate to low usage...
Without usage I can barely get a days use :s
I get the impression that its not the display. I can have 50% display usage, sleep my phone while playing a MP3 and then have more than 50% usage... suggesting that its either he display+something in one category , or there is a bug.
The stock ROM always showed display at the highest usage also. I'm not saying that there isn't an issue, but remember that those numbers are all relative.
I'll say this: I charge nightly to prevent my battery "deep cycling"....That being said I un-plug at 8am and plug-in at about 11p-12a, I use my phone a TON.....usually when I plug in I have about 45-55%.....Not bad at all.....
I originally thought display being the main battery hog was a bad thing.....Then I thought about it a bit......
Would you rather the "system" use more batt? Cell Stand by?
Display (by all rights) should use most battery. More usage=Less time with a fully charged battery.....
Im using CM 5.0.5.3 and I switched Roms after using the stock for 3 months. As soon as I moved to CM I immediatly noticed the battery life was lower than before. I hope you find an issue to this problem ASAP.......I love your ROMs CM, but I love my battery life even more
Good luck with this !!
"display" = gpu acceleration and actual amoled power
Something else i just noticed, very odd. I had 41% display and 23% spotify.... i had been playing for music for a while (offline only). When i quit the spotify app... the entry from the battery usage vanished and display took a spike to 65% ish... really odd. Almost display is showing usage for a group of things.
What? How ? I get 6 hours maybe 7 if I'm lucky out of my battery.... even b4 my nexus was rooted ... how r u guys gettin 24

Ignore any figures people quote - battery life is always relative. One persons 'usual' usage is different than yours. A friend of mine brings his N1 to works and it sits on his desk syncing email - he gets 1 full day.
I bring mine, sync 2 accounts, play a lot of podcasts, have a RSS syncer going and use twitter and FB loads, i get a LOT less.
Dont worry to much, your usage figures are pretty normal depending on your usage patterns.
They say your mileage may vary for a reason
Battery Life
My Battery life has always sucked. Maybe I should buy a new Battery?
If I take my phone off the charger at 7:30, and don't plug it in all day, then I will be at about 30% or less by the time I get home at around 5:30. Unless I don't use it. But I use my phone to play stream music pretty much all day. Or at least 4 hours. One day I forgot my USB cable and I was below 20% by 3:00.
It is still better than iSuck, I mean iPhone, and worse than a BlackBerry. I have electricity everywhere though, a car charger, and an extra battery is like 25$?
So what is the big deal? You have the equivalent of a desktop computer from like 2002 in your pocked running off of a batter the size of a credit card, how long do you really want the thing to last anyway?

Am I the only one impressed by the SGS2's battery life?

After reading through so many threads about owners having issues with the battery life, I thought I'd start a happy thread!
I've had my SGS2 for almost two weeks now and I've always been happy with the battery life because it seemed to last a while.
I'm not up to the stage where i can just leave the phone alone (because I always want to play with it!), but I did an experiment 3 nights in a row to see how much power the phone drains in standby mode.
Each night, I'd charge my phone up to 100% and take it off the charger and then wake up to see how much power is remaining.
I left all the settings as-is and DID NOT turn anything off (eg 3G, etc).
The first night, I didnt touch my phone from 11pm and woke up at 7am to see that there was 97% battery left.
The second night, I left the phone alone at 11:30pm and woke up at 8am with 96%.
The third night, I slept at midnight and woke up at 8am to have 97% left.
If I average it out, it means that the phone on standby drains a lot less than 1% per hour. At that rate, the bettary seems like it can go with minimal use for at least two or three days. But it's something that I haven't been able to test just yet because I'm constantly surfing the net, testing out apps, etc during the day.
Admittedly, I don't have all that much installed on the phone that could possibly drain battery:
Friend Caster
Kakao
Whatsapp
Crazy Colours Live Wallpaper
Seekdroid
Official EBay
Battery Solo Widget
"Standard" clock
"Applications Running" widget
(I've got more applications, but the ones listed above are the ones that might have some sort of network connection and/or widgets that may need to update during the night).
I'm also using stock Vodafone Australia firmware in Melbourne city (in Australia):
Baseband: I900TDUKF4
Kernel Version: 2.6.35.7-I9100TDUKF4-CL331615
Build Number: GINGERBREAD.DUKF4
Does anyone else get battery life like this?
I'm not sure how big a role the network plays in these stats because I'm based in the centre of a major city.
As much as I hate the Vodafone bloatware, I've been reluctant to flash other firmwares like I did on my previous HTC Aria/HTCHD2/HTCDiamond because this one works so well with the battery.
3% battery over night ?. I get under 10%, with all off what can be off, with no funky widgets, no data, no wifi, no nothing. Still phone wakes up in the night for unkown reason and 80% of battery is taken by mysterious Android OS process.
I had Optus bloatware and I kept it for a week or two. I wasn't unhappy with the battery life but wanted to customise it and get root.
After flashing Lite'ning it was obvious how much less battery drain there was. I have since moved to Cognition and I am very happy with how it's going. I charge nightly, but I've never had the battery drop below 50%, and I do use the phone quite a lot. I wouldn't say I'm a heavy user (it's all so subjective) but I would have to be at least medium if not more.
I also love the Black Theme by Nitrozk and Pele, which is why I moved from Lite'ning to Cognition to begin with.

That is a problem with the 2.3.3 firmware mate. Best switch to 2.3.4 ASAP!
To answer your question, yes, I'm hugely impressed by the battery life.
Here's my latest and I'm still at 15%. I'm bone stock on KF3 with all the syncs set to every three hours and using Exchange push.
People blame everything (Wi-Fi Sharing, AOS) for their issues except what they do to their individual phone. Network signal strength plays a big role so does the individual router used for Wi-Fi access. But outside of that there's no other explanation other than individual configuration when identical phone's from the factory get such different results.
I don't participate in battery threads because they're pointless. Dozens of different people using the phone differently with different apps and settings on different carriers all talk in circles when there's no common basis for a legitimate discussion.
I'd call 3% overnight something impressive.
I'll try it out tonight.
I'm running 2.3.3 (No updates avaliable here in Brazil) and i'm not about to root it now. I'm getting a generic 7" tablet to mess around and learn how to do it properly.
So i'll be running minimalistic UI, Snowstorm, Battery Monitor Widget Pro on the desktop, with 2 screens.
HSPA+, bluetooth and wifi disabled.
Let's see how it turns out tomorow morning.
One thing i wanted was to flash in Samsung's oficial fw for Brazil, mine's a carrier customized one, and that's sort of pissing me off since i wanted to uninstall 75% of the garbage Claro has installed here.

I agree with you BarryH... having put the great battery stats in the first post, I wouldn't expect anywhere near that sort of level had I been playing with the phone or I had a thousand apps that run constantly in the background.
Having said that, it seems that there are the people who do have legitimate problems and then there are the people who simply have unrealistic expections of the battery in such a powerful phone. Kinda like buying a big truck expecting it to run on the same amount of fuel as a little car.

Let me know how you go Unreal... I saw on a thread a couple of weeks ago (not sure exactly which one now because there's so many of these "bad battery" threads) that someone had said that their phone lasted more than three days with minimal use.. and noone believed him! lol
How strange, I was about to make a similar thread. I had just gotten 3 and a half days out of my battery earlier tonight, no connection to charger since friday night. Minimal use of course, few phone calls and general tinkering, but still impressed with the standby. It was at 1% battery left so time to charge her up again. I charged my phone till the 100% alert came up, then charged it for another 45 minutes as I heard it stops it dropping immediately to 95% as some others have experienced. I've experienced similar too.
So after unplugging it, I pressed the power button to turn the screen off and haven't touched the phone till just now, about 6 and a half hours later. I pressed the power button and battery widget shows me 98% on the battery. If i was to leave the phone completely in standby and not use it, at about 1% drain per 3 and a quarter hours, that's about 13 and a half days standby!
I'm on 2.3.3 btw.
2-3% overnight drain is along the lines of what I get with KE2 and KF3. Data off, 2G. I get about 20-30% of drain a day, 30 mins usage, 30 mins talk.
I get great battery life on mine, although I have not made a valid experiment using quatitative data
Hopefully, this will be the NEW TREND for all the Android Gingerbread dual core phones.

We have one guy who went five days supposedly. The majority of posts in that thread are just like ours, a combination of moaning and pleased. It all comes down to how the phone is used and what's loaded on it.

Im very happy with battery life. Froze a couple of apps and I was good to go.
First phone I've had that didn't need to.be flashed on a daily basis.
I think anyone that's needs more than a day from a single charge needs a blackberry or a home to charge daily.

I have owned a lot of androids and my sgs2 has the best battery life.
I guess you think it's ok, probably because coming from another android phone, it is.
For me is a pain, every half day have to think about charging, my whole usage of this phone although brilliant, has been taken over by thoughts of how I'm going to next get it charged aposed to what I want to do with my phone.
Something I didn't expect was just how much this phone discharges whilst playing music with the screen off.

Im not impressed, it just met my expectation coming from an SGS1, but the first one impressed me so ergo Im also impressed on the SGS2
I have had this phone since pretty much near release date. I have been and still am very impressed,by the battery life.
I'm currently on KG1 2.3.4, but since before this past Saturday I was always on 2.3.3 (KE2). Even on 2.3.3 with the AOS bug I was still very happy with battery life.
Now with KG2 out, I'm sure ill be even way more impressed.
I love this phone, and I have been a religous iphone user previously too!

On my phone with 3500mAh battery. With yellow arrows, the behaivour during night.
KG1: during 4 days ( no drain at all)
KG2: during one night
I must agree, this is my 3rd Android phone (out of a total of 37 phones since 1990) and it's by far the best battery of any smart phone.
My best battery usage is 3 days 13 hours with 25% battery left. That was with wifi on all the time, over an hour of screen time (I was working at home, so no need to play with the phone) and over an hour of phone calls. I'm sure it would have reached 5 days. BTW, I'm running 5 pages of widgets, firefiles wallpaper and GMail is updating all the time.
During the 3 days time I switched off 3G as this is the biggest battery drainer I have seen. I live in a 40 floor tower which is made of thick concrete and the 3G signal in my home office is terrible, the phone is constantly hunting for 3G. When I'm at home, I don't need 3G as I'm using Wifi.

The Battery on this thing is a monster

I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

Yes, but what's your battery status at the end of this average day? 20%? 30%? 10%?
+1 for an awesome battery!

For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar

Battery gets literally 4 hours before it's dead

I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

This happened to me since i first got the phone it has slowed down and now the phone can last through the day ever since at&t throttled me for this month goes without saying ill take it easy next month. so most likely if your in an lte area thats the problem

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

i can get about 3 or so
5 hours of screen time AND 19hours standby sounds incredible
would sure like to see screen shot as well
and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

Crazy Battery Life on 920

The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
