I unplugged my phone at about 10:30am and at 11:28am it when from 100% to 90%!!!!!!!!!!!! I thought that the battery was suppose to last a good 24hours like Engadget said.
Any suggestions?
its better than most other android phone i had.
10% every hour of heavy use I am not complaining
if u REALLY want to save batter turn off auto sync, gps, bluetooth and other crap

The battery counter of Atirx is by 10%. So, even it shows 90%, that may means 90% to 99%

Mine has been less than impressive today as well. Not good.
Mine seems to be pretty good so far. I think it'll take a few charges to get the most out of it though. I've used it a ton since about 10am and it's showing 80%. That could be anywhere from 80-89%.
Mines been sitting at 90% for about 3 hours now. It shows 90% when it drops down even a little bit because its only done in 10% increments. Pretty stupid if you have a phone to boast about battery... Motorola dropped the ball on that. You basically have a lowered battery meter all day lol
Thanks guys for all of the help!
My battery life has been decent, I unplugged it at 5pm yesterday, drove home with Trapster running (so screen on continuous for 30 minutes), used it heavily playing with it for a few hours in the evening, left it on to wake me up in the morning..
and drove back to work for 30 minutes with trapster when the 5% battery life warning went off right when I got to work.
No complaints here.
Unplugged the phone at 5am and it's 15mins to 12pm here - still full though I did laptop dock it for 5 mins several times to show people at work.

After 4 hours, I am at 75%. Email, tweaking, texting, 2 hr conference call on BT (Finiti w/Motospeak). If you check settings, Battery Manager, touch the Battery... you will see a usage breakdown. This phone is amazing. I expect after a few full charging cycles, the battery should get to full strength.
Is there a way to disable the 3G radio to save battery life (like in the iPhone)?

+1. Do a few charge cycles and then see how you feel.
I got my phone at 30 percent and it lasted four hours of straight playing around with until it hit 10 percent and I put it on a charger. My nexus one would have died with a full charge by then(original battery).
I'll see how it goes in a week, battery life takes a bit to figure out.
Remember that break-in period for batteries when you buy a new phone. Maybe after about a week it will get better? Also maybe try that battery calibrating trick...

Well considering there's no way to know it's at 75% lol it could be at 70% or 79%...either way it would show 70%. The battery only displays at 10% updates.
You can also set up custom battery saver modes in the settings>battery save(think that's it)
My battery life kicks arse. It may be helped with my ultimate juice and tasker, but I streamed rhapsody all day at work on rhapsody, and my battery is outperforming my iphone 4. I'm very thrilled.

Mine has also done extremely well, especially considering it's day one. I've toyed with it all day playing games, music and YouTube along with browsing and playing flash video. It's been outstanding so far.
Battery gauge lies. But it's normal (kind of). See here:
http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
I decided to do a "best case scenario" test, and see if some of my battery issues were from apps gone awry, or some other drain. I pulled my phone off the charger right after it went green, and let it sit on the table. Wifi is off, BT is on, and I'm using my airave, so the signal is a full 6 bars all the time. I have 3 email accounts configured. Two of them are direct push, and one is an IMAP poll once every 15 minutes. Few, if any, emails were received during this test. The breakdown is like this:
4hrs, 32mins on battery. Battery currently at 92%
Cell Standby: 33%
Phone Idle: 32%
Display: 23% (the display was only on for about 30 seconds of the entire test)
Bluetooth: 4%
Maps: 4%
Android OS: 4%
So at least i know there isn't a process running that is making my battery next to useless. My battery seems to be getting slightly better with each day of use, but I still can't wait for the extended battery/cover to be released. I really got used to that on my Evo.
Dave
that sounds a lot better than my setup.
I went from a full charge to 50% with very light usage in 8hrs . I've been asleep for over 7 hours.
Display: 29%
Cell Standby: 27%
Phone Idle: 26%
Android OS: 7%
Voice calls: 5%
Maps: 5%
However, I have horrible reception in my house, even next to the windows. All's fine as soon as i step out the door.
I've found that a weak signal has a dramatic affect on battery life with these phones. They do so much syncing in the background, and it takes so much longer with a weak signal (not to mention it has to transmit at a higher power). The signal makes all the difference.
Call sprint and get yourself an airave! They gave me mine for free.
Dave
do you guys have the display setting on auto or low brightness. My display usage is always through the roog. I am getting decent battery life. I turn 4g off usually and just use 3g unless I am gonna watch youtube videos or sometihng.
I unplugged the phone at 7:15 this morning and I have email, facebook all syncing. wifi off and I am at 92%. So far this phone is being very good at battery life, specially after the first few cycles.

7.5hrs & 70% battery left!!
Is it better to have the brightness automatic or a number like 30 percent?
Sent from my PG86100 using XDA App
I just use auto brightness, I had about 11 hours use and 80% remaining taking a bunch of pictures, a little navigation and texting. This is with wifi on about half the time.
My battery was crap for the first three days with the phone, after calibrating the battery and giving it a few cycles its been really good for me. I do top off the battery usually before I pull it off the charger for the day.
I have mine set to auto and I see it changes even as I'm typing this message. Truth be told, the battery does drain when we don't have good signal...

Auto brightness us worse for your battery. This is because it has to use sensors every set time interval to check the lighting. It's not a TERRIBLE drain, but over the course of 4-5 hours it would probably save you 5-6% if you set it something lower .
And to the other person who asked, your battery life is SIGNIFICANTLY lowered when you have poor signal. What happens is your phone's radio draws extra power when it has poor reception in order to boost its range/signal. For those of you who work in places with poor signal, I bet you can attest to this
Also, I have a few battery tips in my signature if you're interested in more. It's slightly outdated (as in there are more methods now), but everything in the article is still true

Fully charge your phone, then use it until the battery complete drops...Then charge it again
How many cycles have people run on their batteries? IE full to dead?
I have auto brightness, GPS on Bluetooth on, email sync every 3 hours, weather sync evey 3 live wallpapers, and I forget the rest. Battery lasts me 12-24 hours, which is about what I got with my Hero modded out with setcpu and etc. I like the battery life of this phone.

My phone died in about 6-7 hours of steady drain, then I calibrated by doing the same thing they told us to do with the OG evo.
Charge over 8 hours, turn off the phone charge another hour, turn the phone on charge another hour.
I top off by using the phone for a couple minutes, then putting it back on the charger until full. The phone clearly goes down to 95% from full while charging and back up, I like how on this phone you can see that it does it on the battery graph so you know.
I've had my phone off the charger for like 34 hours and I'm at around 48 percent battery remaining. Not heavy usage but not super light either.

69% as of now. I had to reboot today so I can't say this is average. I know there are issues that can't be fixed until root, but as a stock ROM, it seems the power management isn't half bad.

Sense has always been pretty good about power management (especially when you consider the puny batteries they put in their phones), and an asymmetric dual core processor definitely doesn't hurt haha
Just curious what people are getting on their phones. I'm getting about 16-18 hours with Juice Defender with about 10-15% battery left and moderate use (texting, 30 mins games...30 minute call...)
Wondering if any of the Custom Roms out there will extend battery life significantly...Thanks!

I'm easily getting a full day out of it. 8hr shift at work, then getting home and the battery is around 30% on average. Totally fine for me. Also have a 2nd battery just in case it's a busy day.

Yeah I guess I just had higher expectations for the phone..coming from a blackberry that I would charge 2-3/week. I should have expected a significant decrease in battery life due to display, etc.

No high end smart phone these days is going to get multiple days on a charge really. This phone has very good out of the box battery life. Most need a number of early updates to improve the life.
The way phones are now you will never see battery life like you expected. The new standard for me on smart phones is if it makes it through a full work shift then that's good battery life. Some of my past phones I would need to get either an extended battery or have a wall charger in my office. The mofo I can take to work and not plug in until I get into my car and leave.....that's pretty good if you ask me!
Right now 6 hours off the charger with the screen on for just over an hour I am at 78% battery. No calls but texting and some internet. That astounds me for a new phone.
Yeah I guess thats not bad...i was using battery circle but switched to the uot mod....im sitting at 80 after a couple hours....i wanted less widgets on my phone to drain less battery..not sure if it's worked yet

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of 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.

in wp8 is 2 weeks 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.

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.
