Yes, another battery life thread but this one is a recent development for me.
I bought the phone on release day so I have some track record with it. I have not had any trouble with my battery life and have always been able to make the day on a charge. However, recently the Cell Standby and Phone Idle has been sucking my battery dry MUCH faster than in the past.
I unplugged my phone this morning and headed out to work as I do every day. I grabbed my phone at around 10am and saw that the battery was down to 58%. I checked that stats and this is what I saw:
Battery Level 58%
3h 46m 59s since unplugged
Cell Standby - 27%
Phone Idle - 20%
Display - 20%
Bluetooth - 11%
Android System 9%
Other stuff that was nominal >5%
Is this normal? Why would Cell Standby and Phone Idle suddenly be draining the battery when it didn't do it before?

More info on your rom? do you have Wifi calling APP? If you have a custom rom, did you do the battery recycle?
Thanks for the reply...
I am on the stock ROM (rooted). I am not ooposed to flashing a new ROM but I definitely don't want to DECREASE my battery life which is what I have seen occurs with some. Are any of the custom ROM's proven to increase battery life?
I don't have Wifi calling and I haven't done the battery recycle. I fell out of 'tweaker' mode a while back and have just been using the phone. I don't think I have even installed any apps since (or before) my battery life seemed to change. About the only thing different is the Market but I don't think that's a problem.
I just looked and it's down to 38% in 6h 24m and I haven't even touched it. It's rediculous. Something is like a parasite in my phone and I don't know what it is. The only thing running in the "Active Applications" is Launcher Pro but that was one of the first things I installed when I got the phone.

Nero V3 is great for battery life. Also check if you added some apps in the past few weeks. Might be some background sync process taking too much of battery life while in standby.
i've had this issue before and i've found that it was always a rogue app. your best bet is to start uninstalling or freeze them in titanium to find the one that is screwing you up.
one app that was my latest standby hog was beautiful widgets.
Thanks for the tips! I will start removing some apps and see if that helps.

I am not up to speed on the various ROMs. I will go start reading up but is Nero V3 fully functional (camera, GPS, etc.)? I was keeping track of the progress on all of the ROMs but there are now so many and they are updated so frequently it's tough to keep up (at least for me).
Thanks again!
Oops. Double post.
i'm sure it's an app that's causing that. I think a stock rom won't drain that too much.

Does the next update (2.1) somehow include a way to improve battery? I'm guessing no, wouldn't you need to replace the battery itself?
There may be battery performance improvements in the next update. My battery life is actually stellar. I set Timescape to update every 3 hrs and have brightness at about 75%. Off the charger at about 7am and at midnight that night I'm usually at around 40%. That's plenty good enough for me.

I dunno about the update and battery life but, Its 100% to 20% in 25-27 hours for me which i think is awesome as my usage is high.
Try setting the updates of your apps lower, check the Batt usage history from the settings menu to see what sucks the juice more.
If you want more battery life then you'll have to sacrifice some updates, which according to me ruins the entire purpose of having such a high-end smart Android device. Just use the phone the way you like it, have the charger with you always
Whatever phone you choose i think you are going to have this issue since batt usage depends solely upon the way you use your phone. In 2.1 live wallpapers suck more juice so you'll be advised to turn it off its either functionality or performance, the decision is yours
According to me any phone u buy will have same battery life or there is 70% Probability to have worst battery life. X10 has one the best battery life amongst all smartphones

Hmm... could it be just me? My battery went from 100% to 53% from just staying locked over night (around 9 hours). I checked what's been eating it and it said "Cell Standby" and "Display". My brightness is on the lowest possible and Wi-Fi and Bluetooth is constantly off. I'll check that Timescape stuff and try to get the App Killer from the Market... (if my device even had a market!).
nah this device is ****ed up ...
sony homepage says that standby time is around 450 hours .... (more then 17 days!)
i dont have timescape on autoupdate - the only thing i do is gmail push and i get 1 and maybe 1/2 day(s) of standy time (depends if i make 1 call or not )
the update should increase it a lot i think
btw if some1 has a 2nd phone please try this:
charge it fully and then turn it off completely ... after 17 days turn it on ... my bet is it wont turn on coz the akku is totally empty...
I have no Wi-Fi at my hotel and I don't have a data plan. How on earth does it drain this much battery. I'm gonna go turn off every app and try another night just on standby.

Good question for you actually, how long have you had the phone? my first 4-5 charges were appauling but it quickly got better and now i could not be happier. more often than not getting 7am - 11pm the next day (whats that, 40 hours or so?) out of one charge, with plenty of go left.
Mine is running RB##26 firmware, rooted and a chunk of apps deleted though.
When i first got mine it was a bit poo, remember for the first 5 or so charges to let the battery go down pretty low and it will improve battery life.
Get runcpu and you're golden.

Sounds like you're running 014 firmware - I had the exact same problem until I updated to 020. The whole battery usage profile changed and one hour of standby only uses up 1-2%.
yeah, the 020 u/g makes a difference. I've rooted and overclocked mine, heavy usage on 3g can drain the battery in c12 hours but more than adequate for general usage
I'm a big user. Even with my G1, I was happy with a day's use. Anyone who thinks they're gonna get days of use without a charge is kidding themselves. A smart phone with a big screen us gonna suck juice regardless of what you do. As many an XDA user will tell you, keep your charger or at least the cable with you wherever you are. With FW026 it did help a little, but if you need life from your battery you really do need to sacrifice some of your widgets or updates.
MrZ
Today my battery have gone to 10% in about 10/11 hours, i'm using sip and wireless are active all day, even when it are on standby, installed some apps and played some games, some calls, its good enough, sometimes i get 2 days, depends on what you do, you can do some tricks...
So here's the situation...basically am getting about 12-14hrs of battery life. I have been switching roms, sticking mostly with bionix. However it doesn't matter what rom I still average about the same.
I'm not sure what I actually should be getting so I thought I would ask. I user my phone for basic use; texting, checking email, 30 min podcast, and an app or something. I don't game or watch videos.
Can we here what people are getting and if there is something that can be done to get more life on my battery?
Sent from my SGH-T959 using XDA App
The other dozen threads on the same topic didn't provide enough information?
Use 2G/3G Network Switcher and stay in 2G mode unless you really need speeds faster than EDGE (downloading a podcast). For texting and email, 2G is fine and will help battery life. Also using Juice Defender can help as well.
Go download Auto Killer, and set it to whatever level you want.
Also, go wipe you battery stats.
See if that helps...
Yup I've done all the above. Just curious if I'm still getting what is standard. I've searched the forums but if you know the best place to look then point me in the right direction. Keep the advice coming

12-14 hours is pretty good. Best I got was with Franken-Twiz 3. I think the J16 modem in Franken-Twiz 4 is killing my battery faster so you can flash Modem J12 or try Bionix 1.8 which has Modem J12 in it.

Welp with 3g and wifi off I'm easily getting 16hours and on average I'll have 50-70% left of my battery.
I just normally use it as a phone thou. You know some emails, text messages, some surfing.
Just in case you think I'm nuts heres a screen shot as of now. 98% with 3hours on the battery and 48% with 16hours on the battery.
Last night I went to bed at 10pm and my phone was off the charger since 6am and I had 72% on the battery.
I've learned the more you fiddle with your phone the more battery it uses obviously. I've had several phones so I don't have to constantly play with it. Play videos or stream and well it will eat batteries. Use GPS and wifi it will destroy your battery life. Of course I'm not a power miser, but honestly I use it when I need it and when I don't it just sits there until I do.
Got it thanks

I'm getting similar performance with the JI6 OTA, and I generally leave both GPS and 3G on all the time. I just checked my battery stats and my phone's been off the charger for almost 4 hours and my battery percentage is still at 99%. Granted, I've only made two short calls and checked e-mail a few times but I'd call this very good performance. I also woke at 7:30am and surfed around on my phone reading forums and web sites (my display was on for the ENTIRE hour+) for over an hour this morning and when I plugged back in at 8:45 am, I'd used less than 10% battery. I'm also noticing that my phone is charging WAY faster than stock or JI2.
Personally, I have posted about this topic many times but I'm ignored. My battery was terrible before I rooted and did OCLF. After root+lag fix my battery literally tripled in life. I could go 2 days with the same amount of use. Watch videos, surf internet, make calls, do whatever and it would barely use my battery. After this JI6 update I am back to square one. I 'reconditioned' my battery by running it down to zero then charging it back up completely. It definitely helped but I'm still losing a percent by the minute just having the screen on.
Dont waste your time telling me to use juicedefender, turning off wifi, switching to 2g only, task killers, blah blah blah, or any of that crap. I've done it all. I"m still looking into the JI6 radio draining my battery though. Theres a lot of talk about that being an issue.
The JI6 Modem does drain your battery. No doubt about it. I've switched to JI2 and yes my GPS appeared to have suffered a bit and sometimes my Edge connection isn't as good as JI6, but way better battery life.
Or you can do what I do and leave your headphones plugged in and leave the music playing overnight. Seems to make my battery last about 2-4 hours more than it regularly would. Hope that helps

I have uninstalled any battery app because I noticed they drained my battery faster. What I have noticed about the phone, when I charge it with lets say 25 percent still remaining it charges faster,, naturally,, but the battery drains much much much faster. To remedy this,,i use the phone until the battery icon is blank and blinking before I start charging the phone. Naturally, this causes the phone to need a substantial amount of time to charge however the battery doesn't drain nearly as fast. I am a heavy user btw...give it a shot and confirm what I say.

I flashed bionix 1.8 two days ago, charged it up, wiped the battery stats, and let it dry clean.
The phone was in Auto mode for EDGE/WCDMA, reinstalled/downloaded my apps and some more, tested GPS on a few occasions, watched some HQ content on Youtube, and tested VideoPlayer, a few calls, some SMS and MMS, I listened to my music for the most part on it. 30+ hours later the phone finally drained.
With any stock FW's I could not get through more than 24 hours of a regular use with 2G mode only.
Currently I am at 79% at 11hr mark since unplugged.

True. You have to sacrifice something.
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.

Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I have been experiencing some serious battery drain issues. Looking at my battery stats, "Android System" is responsible for over half of the drainage. These are the only apps that run constantly besides those which the phone requires to operate:
- SetCPU
- HDWidges
- The Weather Channel
- LBE Privacy Guard
- avast! Mobile Security
other phone info is in sig. Any insight/advice??

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

So this worked for you? I am having excessive battery drain with my Telus S3?

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
I'm not very happy with the battery life so far. Some website had tips on getting more battery life and one of them was to turn the screen brightness all the way down. That's way too dark. I keep it a little less than half.
I always have it 100% charge before I go to work. I normally work 8:30-5:00, but today we had some snow and went in at 11AM. So, today we skipped taking our morning tea/coffee break, which I'd normally be using my phone on. The only thing different about my morning is that I used the alarm clock 2 more times than normal.
All I did so far was listen to 3, maybe 4 videos on YouTube on my drive to work through bluetooth, check a few notifications, and my lunch break I updated every app that said it had an update.
I'm down to 45% already!
If I go into battery to see what is using my battery, everything in there only adds up to 20%.. so 45% I have left + 20% I just mentioned = 65%.. where did the other 35% go?
Screen 7%, Mediaserver 3%, YouTube 2%, Android OS 1%, Android System 1%, Phone Idle 1%, Google Play Store 1%, Google Services 1%, Cell Standby 1%, Wi-Fi 1%, Chrome 1%.
I've got hardly anything installed since I just got the phone. Haven't even rooted it yet. Only have about 4 apps installed, which I mostly don't use yet.
Nope best battery life for me. Up to 6hrs sot
Yes - the battery life is atrocious - despite doze. Greenify with aggressive doze does better. Some times nothing kicks in and the phone shows a straight line of battery death. I am no talking rooting and beyond - I am talking straight as it is.

I'm rooted and running several apps that take advantage of root.
Nova Launcher Pro
Kernel Auditor
Root Explorer
My battery life is amazing. Can go all day from 7am-5pm and have about 65% left.
There's already a big battery life thread that is still active and is full of good information
