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.

Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

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!
Hello.I use this masterpiece about a year now with really heavy usage.I almost charge it every day,or about 5 times a week the less..In the first 10 months with KITKAT i had always about 10-11 SOT hours.After 10th month also with kitkat,SOT reduced to 9-10 hours.At this point i updated to lollipop cause a certain mod that wasnt supported from kitkat.The SOT about 1 month remained same as kitkat.And finally the last month i notice that SOT has reduced to 7-8 hours.Also to mention that after 8th month the battery has veeery sudden drop from 16 to 8%.It drains about 1%/minute!From 8% and bellow it drains much more smoothly compared to 16%—8%,but not as smooth as 100%—16%.Is there any way to calibrate battery or to find out if is battery issue?
Thanks for possible help.

For starters, if there was a 8 hour reduction in SOT in the course of a month, something must have happened. Either the way the device is being used, or the apps you are running. No two ways around it. Also, if it drops 1% every minute your battery has either become defect (dropped the device lately?) or again, something is draining it.
There are apps you can download to check what drains the battery and hog memory etc. Don't know their names, so Google it. Otherwise, I would do a back up and then do a factory wipe. Test the factory wipe for a day or two without restoring and check if the battery drain remains the same. If not, there is indeed something you are running that is causing it.
Lastly, our Li-Ion batteries lose their capacity over time. SOT will significantly reduce over 15 months or so, depending on usage maybe earlier. If I leave my screen off the entire day I lose around 15- 20%, if I use it I get maybe 4 to 5 hours playing games with my Bluetooth headset connected and WiFi/LTE. If I watch movies it's a bit less. Just how it is.
thanks dude.i loose 1% only between 16%-8% very weird..no i never dropped it and i notice that battery drops the same way either when is just formatted or not..if i leave it allday with screen off i loose just about 2%...
I don't know why but the android system is always high instead of the screen. And I see people getting 12hrs of Screen on time where I am only getting hardly 7hours. :/ I tried many roms, but all seems to have the same problem :3
The battery life is usage dependent, as well as statistics. You need to figure out what is causing the battery drain in your case. Check what functions of Android System are using the battery and check what apps are using those functions.
7hrs sot is normal.

From what battery level to what battery level you analysed to have 7hrs sot..?
I am on stock miui 9 and i get 6hrs sot at 50% battery left. And 9:30hrs sot at 20% battery left.
I don't go beyond this battery level, prefer to charge back to 100%. I had similar result on stock Miui 8.5.
try flash AOSP-CAF bro with its default kernel,, i got >24hrs of total battery use and >9hrs SOT,, plus this ROM is smoother than Miui9.. Thanks me later
if you use your phone for 2 or 3 days, 7 hours is normal buddy... becasuse the standby consumes battery too...
if you use it non-stop, you will get 12hours of SoT...
So i regularly use AccuBattery app in my android device. It's a very useful one.
So i installed this on my new Poco X2. Those who've used it know that it can estimate your current battery capacity based on charge sessions and some other stuff.
And upon using it showed my Poco X2's estimated battery at around only 3800mah.
And a lot of users also are complaining about battery backup on flipkart.
Please check and post your device's estimated battery capacity via AccuBattery app.
Unfortunately, what Flipkart reviews say is actually right, this phone has serious SOT problems with 120 hz i only get 6.5 hours sot and 8 hours with 60hz and I don't even use it heavily just YouTube and small games with social media. This phone has very poor optimization. I know i shouldn't compare but if you look at realme 6 pro almost same specs but with smaller battery (4300) gives 1 hour more SOT even with heavy usage(both set to 60hz). This is absolutely disappointing, eagerly waiting for custom roms and custom kernels to make it as my daily driver. Will update you on the accubattery results

Thankyou, waiting for it.
Bafore this I was using standard China Rom with mine and battery was a mess. But I unlocked & flash MIUI.eu. I add-on "naptime" to help with Doze & using Universal GMS Doze magisk module. Managed to get almost 8hrs SOT with ads removed, bloatware removed & MSA removed. Maybe you should give it a try and see ?
Same
Battery is fine for me
Don't know how people here getting more than 3.8k mah estimated. Mine doesn't go above that. I'm pretty sure some units have battery problem as reported by few buyers on Flipkart. Some said battery is excellent while some said poor battery. I think poco x2 indian units are suffering more. Since after watching some tests on the redmi k30 Chinese variant by YouTubers they got significanly more SOT. I tweeted to them, no reply from their side yet ?
I got my K30 directly from China. No battery issues whatsoever.
I've been getting consistent SOT of 9.5 hrs on average with heavy use. SOT range for me has been 7 hrs (120Hz) - 11 hrs (60 Hz) on 4G LTE (you can check my post on SOT thread).
Being a heavy user, this battery life has literally blown me away and I absolutely love this phone simply for that. I can easily get thru a very heavy day with 30-40% battery left. I've been charging the phone twice every three days on average.
I'm on stock CN ROM (MIUI 11.0.13 Stable)
I easily get 8 hours + SOT with gaming. I play cod and pubg extensively.
Battery life update after using a month .
Mild gaming and social media usage.
Average sot is around 10hrs , battery lasts 30-50hrs depending on camera usage.
Unable to upload screen shot showing bad request.
Is AccuBattery reliably on first cycles? If many users have 3800 mah insted of 4500mah then something stinks here
My poco X2 shows 4398mah
I am on stock Indian rom miui 11.0.10
I did some quick research across the web and it looks like there are three types of d
1. Battery Drain issue devices, they have bad battery issues, battery capacity way below 4500 and widely varying with users. Screen off discharge is way off charts, like >5%/hr. SoTs varying around 5hrs or <5hrs
2. Inefficient battery devices. (Majority) They have battery capacity much below the specification, however less varying, always around 3800mAh. Battery doesn't drain that badly
I have this device, heavy usage like pubg clocks around 15-20%/hr, normal usage around 10%hr and screen off discharge rate at 0.5-0.9%/hr. Hardly discharges 2-3 percent through the night
3. Ok devices. These are the best sets. Battery capacity constantly goes above 4000mAh (still doesn't hit the required 4500 mark tho). No serious battery drain issues. (I don't know much about these devices because they don't look into the web coz they have no issues.

Usually i get around 9hrs 30 min sot on 60hz and around 8hrs on 120hz...( Without gaming ) after the update of miui 11.0.11 my phones battery backup gradually increased 1 hr on 120hz...+ I did some tweaks blocking system apps from running in the background
After using the phone for 8 months, I noticed that charging speeds have significantly reduced. At the beginning, the battery went from 0-100% in ~70-75 mins if I remember correctly (cross checked this with another review website).
But when I properly checked today (after a long time), it took 118 mins (2 hrs!) for the battery to go from 2-100%. I also plan to check this with the screen/phone off again.
The battery life is still great though, maybe slightly reduced compared to the beginning.

Original charger used and the cable is in perfect condition.
Re-tested today with the phone switched off and it went from 4-100% in 70 mins! So all is good. Planning to test tomorrow again with the phone switched on.
Battery life is still stellar. 8.5 hrs of SOT for 26 hrs of usage on 120Hz; 70% WiFi and 30% LTE.
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.

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
