Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.

I know this has probably been asked hundreds of times and I have searched up and down the forums but have found no fix for my battery problem.
I always have my battery at the dimmest level. Mostly only text, the occasional 5 min phone call and web browse here and there. Yet when i look into the battery use the display is always at atleast 96% ive never seen it less than that. But i kno that it has to be something other than just the display though.
I stoped using beautiful widgets, and froze media hub (i read that it eats battery in the bg) recently ive been monotoring my system through system panel.
As of now system panel tells me that System Processes is at 5.7% and system at 2.6% The next highest thing is Swype at 0.4% and android.process.acore at 0.2% the rest of the things are at 0.0%
I was thinking that it might be the battery or just the phone itself...

Having your screen use that much (as a percent) isn't necessarily a bad thing. It means that everything else is using minimal power. You also shouldn't be checking your stats for useful info within moments of turning it on. Give it a whole day of use and check again. Your screen will have used less % after a day but it is totally normal for it to be the largest user of power.
So then what could be causing the battery drain?

How much drain?
You should expect to get 4-5 hours of use from your Vibrant. Total time could range from four hours to several days, which is what you hear people saying in most battery threads. What they often don't state is how much time the phone is actually in use and whether you get 5 hours or 24 hours before you hit 0% battery you probably are using the phone (screen on for anything, or screen off while listening to music or talking.) for 4-5 hours.
So is your phone getting less use then that? If so then you may have some other issue.
http://forum.xda-developers.com/showthread.php?t=848207
The links are very informative
Of actual use, not just standy by I get just about 4 hours. Usually under 4.
And that link looks pretty interesting

Fast Battery Drain
Bad News Everyone!
I have spent the last 3 days searching here and other forums trying to find out why my battery has been horrible. My battery goes to around 30% after only 3 or 4 hours of very slight use (2 or 3 texts and checking email once).
I have done two complete battery drain to full charge with the phone off the past two days to try and get a better reading.
The history of the drain, at the end of November I rooted and installed RyanZA OCLF, rooted, and lag fixed, no issues. Installed the basics of rooted (busybox, superuser) and SetCPU.
SetCPU presented problems with not coming out of sleep and freezing after reboots. The battery would give about 6 hours of moderate use. I played around with settings, but ultimately removed it and when I did my battery was lasting 3 hours longer with moderate use, facebook, twitter, browser, 20-30 mins of gaming. From 12:00 pm (leaving work) to 9:00 at night (leaving school) with 35-40% left before I got home.
About 4 days ago, my battery was draining very quickly. Wake up, unplug phone at fully charged, get ready for work, grab phone to leave for work and I am down to 90% after only 20 minutes of standby. When it use to have it around 96% by the time I got to work, about an hour with light use. Seeing this problem I went back and looked at updates and apps that I had. The only thing I could think was Launcher Pro, but no one else has reported battery drain issues and it wasnt showing in Battery Info.
In my attempts, I have done the following.
Went from 7 to 3 screens (one widget per screen)
Removed apps and bloatware with Titanium Backup
Doubled checked my account syncs, Facebook once a day, no twitter sync,
Screen brightness at ZERO
2 Battery Resets (fully drained to recharge phone off)
Installed Watchdog to find any heavy mem/cpu users, (none found)
And a crap-load of googling, forum searching (here and cyanogen forums), and I am still getting horrible battery life.
Today for example: Phone completey charged 10:30 am with only 3 texts sent and I am currently at 28% at 3:15. 5 hours of stand-by should not have drained that much battery. No GPS on.
If you have any ideas of what it could be, at this point I have alread bought a new battery, I would love to hear back.
edit: I am running stock rom 2.1-update1
I used to have poor battery life as well on stock 2.1 rom until i flashed the leaked jk6 update. Im now averaging about 25 hrs per charge with my phone pretty much always in use whether its calls, texting, music, gaming, web, movies ect...
Not to mention i also get 3g in places i havent before and faster DLs, less lag... This rom is awesome, i suggest giving it a try..
Sent from my SGH-T959 using XDA App
dubbz106, thanks for the advice. I have not had a huge desire to flash a new rom because my phone had performed pretty good. But with my G1 I was keeping it alive through cyanogenmods.
I have been moving closer to flashing and this new battery issue my push me to do it.
Can you link the thread for the rom?
The S2 is essentially unusable right now, with the battery drain problem. I have tried everything described on these forums. reflashed the phone a dozen times, reset and tried every thing in the book. Only thing left is reflashing backwards to KE2.
Does that offer a less of a battery drain, than say the KE7? Mine is at such a bad spot right now, its not funny. Running stock KE7 with 3 apps installed, it's lost 30 percent in 3 hours. or there abouts?
Did u try to turn the wifi off ? I recommend you to try out the Juice Defender app which help improve the battery by controlling wiring and other connectivity. It will auto turn off wifi when screen off.

i Have KE7 installed. Its rooted and i am using Antek App Manager (free) to freeze some of the samsung crap plus using Android Assistant to clear cache and close programs etc. My battery is pretty good. last night, on a full charge, found out in the morning it used only around 7% of battery. During the day the battery usage had been good too. Wirless is on and background sync enabled, battery on 66%
I had KE7 installed from the off. Battery life has been improving for me (Only had the phone about 10 days)
I keep things down to a minimum (no Wifi, bluetooth, background sync).
I managed to get nearly 3 and a half days out of my last charge. This is with occasional texts, emails checks, phone calls and Google reader updates. I use launcher pro and have set the weather widget to update every 3 hours.
The battery on my Orance San Francisco hardly used to last 2 days with similar usage.
With the screen size & processor power, I for one am very happy with the battery life of my SG2.

None. I was snoozing. The handset had been taken off the charger, email account configured and i had taken a call. Fell asleep after that. Screen on time was 78 percent. (Only apps open were a gmail one, 3 browser windows and titanium)
Great life here
Just to add a counterpoint, I'm running stock unrooted KE2 and am having incredibly great battery life. No frozen apps or battery management apps, other than the stock settings that kick in after 50%.
I recently forgot to charge overnight, and still had >40% battery left after around 36 hours of moderate use.
This is with auto screen brightness, WiFi always on, no syncing except for gmail/contacts/calendar (With a fairly high degree of gmail traffic).
During that time I played Angry Birds, used GPS navigation, send numerous texts, emails, and phone calls. Recorded about 10 minutes of 720p video, took a bunch of photos, and browsed the web periodically.
I'd love the OP to send it back, and see if his new one had the same issue. Maybe it's his 3G, or maybe a just a bad unit? You paid alot of money, something this serious send it back.

There is a huge gap in the middle where you didn't turn on the screen, for like 16 or 18 hours (except once).... Be honest, while sleeping, do you hibernate? hehehe.

Planning to do that today. Got just a couple of days left on return policy. If not.. well i am stuck. I love the phone. I want it to work... but 5-7 hours is just nonsense. I hope 2.34 ships soon and sorts out the mysterious drain.
Yep KE2 has much better battery life than KE7. For me anyway. I can get a full day's use out of one charge with moderate use and screen brightness set to 50%.
I have also frozen all the bloat. In idle with email set to push the phone uses about 2% an hour. Which is not bad in my books.

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 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.

exactly how much screen on time do you have by the time its at 85% ? because i mean, it can go on standy for days with nothing on

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.

Hi everyone, I'm relatively new to using android devices, i've played with some of the devices my friends own as well as a tablet my brother owns but this is my first personal device.
Anyways, I've had the phone for around 3 days now? It's going great but I feel like the battery is draining a bit fast and I'm not sure if I'm "normal" by standards or if my phone is slightly problematic.
I've attached the two screen shots below
Man things I do on my phone are Gmail, Push email for work, browsing, WhatsApp, Gchat and occasionally music and maybe 20-30 minutes of video.
As you can see from the graph there were two very short moments where I was charging the battery as well due to transferring some files. Finally, I've had a chance to completely drain the battery once but haven't had a chance to do one of those long charges people talk about but have through multiple charging occasions gotten it to 100, although right when I unplug it it goes to 99%.
Thanks!
EDIT: My phone wakes up quite a lot I think because I quite a few work emails a day, around 80-100 in addition to another 20 or so gmail emails a day. Thanks.
I have my own problems about the battery life too. Specially on standby mode all turned off (wifi,sync,gps,data,etc) 93% when I sleep then when I woke up battery goes down to 80%
are you too experiencing this as well?
haven't tried that yet, I attributed my battery drain to email, could be another problem then.
Start with Better Battery Stats from the market and look for wakelocks .

There are a few posts on battery issues.
I too had battery issues and in my case it was a couple of things.
I put the screen onto auto brightness and put wifi onto off when phone asleep.
These 2 things fixed my totally. I know lots of other people are having issues and its neither of these things but these are what helped me.
I also got an app to stop apps starting up. There are a suprising amount of apps that start when your phone starts up that you dont need to be running.
I think having wifi on constantly and getting 19 hours out of a charge is darn good for android.

I have experienced this after about a week of use. I left the phone when it was 95% and after an hour in stand by, it drops to the 80 something mark, b/w 84-86% any more people who experienced this?

Same here. Drain is about 2.5% per hour on stand-by overnight.

Yup, I had WiFi on pretty much on at home and at work and it certain does chew through your battery! Started at 7am at 100%, back home by 8.30pm and at 20-30%. By 10-11pm, it's on charge again.
Usage is fairly average, x2 30 mins of music to and from work, emails on push, send and receive texts, a couple of calls here and there.
I didn't save snapshots of some tests I carried out, but I'll try to recreate the situations again and upload them.
It seems if you have your WiFi settings, Keep on during sleep to Always, it's constantly draining your battery, even if your handset is on standby. I've left mine to Never, but have found only a small improvement to battery life.
Attached is my current usage WITHOUT WiFi as much as possible, there are a few power spikes where I've had to use WiFi and to connect to PC to transfer some documents, download some Apps. Also I'm NOT at work for the last two days, so usage has drastically dropped. Loooking good at 2D 1H 50M, battery at 45%
You can see for most of the first day where I haven't used WiFi there is a slow, but steady drop, the first major drop was when I was playing a game on the way home, then it's steady again. The biggest drop was when I used WiFi to download the odd app or two, then I turned it off again.
Hope this helps the OP in answering some questions about finding out what is draining the battery.
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 ?

don't judge a phone's battery life until a week later.

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.
