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.

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?
Install this app:

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 ?

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.
Hi guys, I don't know what's going on, but my phone's battery has just turned to crap recently. Today, I left for work at 7 with a fully charged battery, and hardly used it aside from a few texts. By noon it was dead in my pocket out of nowhere (my battery saver mode never came on any of the times I did check a text). After that, I threw in my second battery at 12:30. After browsing on my phone to 87% on my lunch break, I started checking on my battery from there:
Within a half hour, my battery life went down 7% to 80%.
Another half hour passed, and it was down to 77%
After another half hour, 74%
By 4:12 PM, my phone was at 68%
54% at 4:45 after reading and replying to one email
Looking in GSAM, I see that 57% of my battery is used by apps, with Android System taking up 18%. OS Services is also my highest data use today, at 16.9 MB. Screen wake is only 1%, so it isn't a wakelock issue. I have sync, bluetooth, wifi, and NFC turned completely off, and am on LTE throughout my work day, with a good connection.
Strangely, even though my phone is in my pocket for most of the day and GSAM says Android System is #1, the built-in battery usage setting shows Screen as #1, followed by Android System, then Android OS.
I'm honestly at a loss right now. I can't think of anything new that I've downloaded. My phone usually makes it through an 8 hour shift fine and then some; the thing has pretty darn good screen off life normally. Please help me figure this out!
I think, because it happens to me at work, that is something related to marshmallow amd wifi, Try to go in the advanced wifi settings and select only when connected under the second option in the menu, Then See if it is better.
Another person that works with me has the problem with his s7 edge so i thougth that it could be related to the wifi bug of marshmallow

Hey folks, see if this is the right forum to post this.
Like some other people on here and on reddit the latest Android 11 update C.57 caused a lot more battery drain on my device.
Before on A.46 my over night drain was about 2% which is good I think with Wifi on.
With Coloros 11 it can be over 10% drain over the course of 6-8 hours which is far more.
I have tried gather info from my phone which app is draining but it looks rather normal.
Even tried the adb command to force the phone get the phone to do the battery optimazation manually without luck, seems I have dont have the permission to make suchs commands through ADB with USB-debugging mode enabled..
However this morning I found in Settings>Battery>More Battery Settings>Optimize Battery Use
The whole list on every app there was set to "Always ask" and not "Optimize Automatically"
Now I changed every app to Optimize Automatically and will see how this affects the current drain.
I read somewhere that to the phone to get to this "state of battery optimazation" you need to have the phone in the right state to execute that which was Battery Full on Charger in idle mode not moving for a few hours.
So I thought if the battery optimazation settings where set to "always ask" (which it never did) this state maybe never happens?
Anyways feel free to share your battery settings and what Battery standby drains you guys got because I have been going a little nuts over this issue haha.
I wouldn't bother changing the battery optimisation settings, they seem to reset themselves.
I wasn't getting great battery life so finally did a factory reset. After a week the battery settled down and is now ok, probably around 5.5 hours screen time a day at qhd 120hz with always on display in from 8am to 11pm. I don't really check battery drain overnight, I will check it and report back.

Yes I checked them again now after you mentioned it and they do seem to reset. However now my phone seems to work how it should, currently 3 hour screen on and 64% battery left. Wifi at home all day. Also the standy drain is night and day better now. Maybe this was a bug in Android 11 that kept it from optimize the apps?
I have adaptive on both refresh and resolution and same Always on time settings as you.

Glad it's working better now. I do find the battery a bit inconsistent, some days it's great and others it goes down quickly. I've turned location off now as dont need it that much, I lost 3% overnight which seems good to me.
I really don't understand how you guys get such a low battery drain overnight.
On ColorOS 7 I had 10-12% drain overnight.
On ColorOS 11 it stayed the same. I have reset my phone, now it's about 7-8%.
This is with night optimization on in the settings. 5G disabled.
I always was able to get that 3% on my older OP 7 Pro. Even on my Realme X2 Pro, which had the same OS!
Also, my SOT is not that good. On mixed data/wifi I only usually get 3.5hrs SOT. After the reset its 4hrs now.
With 5G on it's unusable, even with good coverage here. (AccuBattery: 6hrs SOT, 57hrs standby, just very bad)
It's nice to have Dual SIM now with Singapore EX, but I cant use it, my battery just can't handle that.
I kept this phone just because the rest is awesome, but the battery is such a letdown.
I thought it was a SD865 problem, but I also had the Mi 10 and Poco F2 Pro as a secondary device without any drain problems.

3% seems good.
However I had a big drain again over night so gonna try to set apps to optimize again.
It is indeed very inconsistent

I really don't understand how you guys get such a low battery drain overnight.
On ColorOS 7 I had 10-12% drain overnight.
On ColorOS 11 it stayed the same. I have reset my phone, now it's about 7-8%.
This is with night optimization on in the settings. 5G disabled.
I always was able to get that 3% on my older OP 7 Pro. Even on my Realme X2 Pro, which had the same OS!
Also, my SOT is not that good. On mixed data/wifi I only usually get 3.5hrs SOT. After the reset its 4hrs now.
With 5G on it's unusable, even with good coverage here. (AccuBattery: 6hrs SOT, 57hrs standby, just very bad)
It's nice to have Dual SIM now with Singapore EX, but I cant use it, my battery just can't handle that.
I kept this phone just because the rest is awesome, but the battery is such a letdown.
I thought it was a SD865 problem, but I also had the Mi 10 and Poco F2 Pro as a secondary device without any drain problems.

Yes I agree the battery drain is very weird with this OS.
Have you tried changing the settings in the battery optimize section? I turned on optimize automatically and then charged my phone full and let it sit for a while with charger plugged.
Try this and see if it gets better.
Its weird that the settings change after a while tho.
Just recently managed to use the phone and have to confirm ColorOS 11 is killing battery overnight, I have this for few weeks now so should be all optimised, yet still overnight is around 25-30% battery gone, my previous mate 20 pro was taking maybe 2-3% overnight so is massive hit. No notification is allowed, do not disturb on with wifi and mobile off, really weird is behave like something in the background was still on.
mine only about few percent but my battery life sucks at 4-5 hour ish
