I know there are a lot of threads already but bare with me....
A lot of users have been having issues with battery (me inlcuded). These are the following things I have personally tried:
Screen Filter
Freezing Apps in Titanium
Green Power (though I had issues with it not enabling data when screen on)
I have tried VillianRom the CF-Kernel and currently I am on stock K7 and the stock Kernel (rooted using insecure kernel then flashed stock again)(figured that might help since Samsung wouldn't actually sell a phone without testing the battery).
I am not a gamer nor have I been abusing my phone. Today scenario:
(3G/HSPDA always switched on or wifi when available)
Removed phone from charge at 1400 Hours.
Wifi was on till I left home at around 1530 hours during the process I must have barely checked a few messages on Whatsapp and made one phone call. Since then I have been out met a few friends showed off the phone. When I say showed off the phone all I did was this:
Showed the S2 playing a video
Played a song from google music (streaming over 3G)
Used whatsapp for about 10 minutes
Spoke on the phone for a total of 30 minutes
Got back home around 2200 hours and the phone was screaming for attention which I believe on stock is around 15%.
As you can see from above I have hardly used the phone. Now my query is for those users who are not having battery issues. We have had a lot of threads complaining about issues can we just have a brief post from you guys who are having fantastic battery?
Something like:
Firmware
Rom
Kernel
Root Status
Applications Installed/Frozen
Other Steps?
How much juice have you gotten out of it
I think all of this would greatly help. Coz clearly some of us are having problems and some aren't so could we just share the knowledge?
Sorry for my rambling but I wanted to explain all of it as clearly as I could. Instead of starting another thread as to WHAT CAN I DO!?
Cheers.

[UPDATE]
I read this in one of the countless threads regarding battery life and android OS eating away battery. Still in the testing phase but it seems this might be a genuine solution as well :
Format your SDCARD. I know sounds stupid but like I mentioned earlier I am still testing this out. Most of us if not all have shifted from our old android to the Galaxy S II. The probability that this might have been without a format to save pictures or some sort of data is most likely. Once again this *might* help. The title hence states update and not *FIX*.

Firmware & Rom: I don't know the difference between firmware and rom, so I'll put this: Baseband - I9100BUKE1
Kernel: OEM 2.6.35.7-I9100BUKE1-CL182896
Root Status: No
Applications Installed/Frozen: None
Other Steps? : Wifi on most of the day, 3G off unless necessary. GPS off Screen brightness: auto
How much juice have you gotten out of it: 4 hours of screen on time, or 24 hours of light use. Usually 16 hours of 3.5-4 hours of screen time.
I hope this helps. Ah not to mention, I have had this phone for 5 days now, and I haven't had ANY Samsung apps show up.
Here is an image of my list of services, but I must say, I unplugged it last night at 10 PM, and left it mostly alone until this morning. That's why my screen usage is so low. In other threads i've posted a lot higher screen on time . But it's just to show you that on KE1 there is no Samsung services going rogue.
One step forward two steps back while charging!
I had the bizarre issue last night where my S2 was losing power while it was charging. Only app running was Words with Friends (checked cpu usage and seemed ok) and I had Screen Filter running at 60%
Phone was near dead by 9pm even though I had topped it up during 2x 30min drives. Was playing Words against 4 family members (all on their iPhones) and I had to give up trying to play while huddled on the floor by the socket as it slowly dropped percent by percent lower.
Not Happy!
KE7 btw
I had a ****ty battery life too but then after reading some tips how to improve it, I froze wifi sharing in Titanium Backup and disabled Google Latitude (not sure which one did the trick but if I had to choose, I guess Latitude was the issue since Maps was always showing up in Battery usage) and now my battery life is perfect. Before my phone would die after like 8 hours and now 24 hours is no problem . I hope the new firmware will fix Latitude but until then, battery life > Latitude. I'm on VillainRom 1.1 and CF-Root 3.7 btw.
ActiveSync
I had an activesync account which really chewed on my battery, had only about 12 hours battery life. After removing the activesync account it lasts at least 40 hours!
i have mobile internet on 24/7, everything syncs every hour, if i dont touch my phone all day, it drops from 100% to 90% from 8am to 4pm....I use my phone for music most of the day for music, txting ect, easily has over 50% by end of the day...cant understand why so many people have problems!

Battery is always the problem and it will hinder the development of smartphone or other PDAs. Maybe we should get nuclear battery
Always turn 'mobile data' off when you are not using your phone. I travel a lot with work and can tell a huge difference in battery life depending on where I am. If you leave 'mobile data' on where 3G service is bad, your battery will drain fast.
Firmware - Default KE2
Baseband - I9100XXKDJ
Kernel - 2.6.35.7-I9100XWKE2-CL187606, [email protected] #2
Other - 3G connection, no 3G packet data, no WiFi, no GPS, looking at the time from time to time, screen brightness either small or auto
I have none of the problems mentioned by others (like display banding, tint, unstable WiFi, the pink camera spot is small), if this makes a difference.
(By the way, the number within the battery compartment says i9100H)
I get about 11% battery discharge per 24 hours

Whichever way you swing it, Android battery life ain't that great... i'm coming from a Nokia phone which had 7-10 days per charge.
S2 is my first Android phone it's stock unrooted, Optus Australia version. With 100% wifi on, I get 9 1/2hrs out of box, 19-20hrs with Juice Defender free and 52hrs with XP8000

Haven't flashed it yet as phone is only 10 days old, so giving it sometime and probably wait for 2.3.4 to come out. I know KE7 is meant to give me better battery life, so may do the update or wait for 2.3.4.
My advice just get an external battery pack. My Energizer XP8000 will give me 2-5hrs extra S2 battery run time per 1hr on the charge (basically every 1hr 25-30% charged). So if you're away from home or at work, plug in XP8000 for 1hr and give the S2 a 2-5hr top up charge. But probably quicker to charge on S2 AC adaptor as USB = ~450mah and AC = ~650mah. So on AC every 1hr on charge = 40% top up on S2 battery life.
The added bonus of XP8000 is it has tips for 1000s of devices, so i can use it for my Acer 3810T notebook too which gets 10hrs itself and XP8000 can give it an extra 4 1/2hrs on top.
One thing I notice is I'm getting better battery life after each successive charge, with Juice Defender free started out around 17-19hrs, then 19-20hrs and now 23-26hrs. Been charging off XP800 @450mah for past 4 charges maybe it conditions battery batter than AC @650mah ?

A phone and a PDA (so called smartphone) are two different animals.
I forgot to say that my 3 years old HTC Polaris (with Windows Mobile 6 and a 2.8 inch LCD display) had about 12-14% battery discharge in the same conditions (but the battery was smaller, like 1300 mAh). Just for comparison for those who believe that Android is at fault.
Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .

Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.
Thanks.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.
Sent from the little guy
Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.

I am running Android 6.0 Marshmallow on my Nexus 9 build number MRA58N. Device is not rooted but the bootloader has been unlocked and I am running everything on stock. Clean fresh install about 5 days ago. I did face some trouble trying to root my tablet at first (boot loop) but instead I formatted and just reflashed the firmware clean using (flash-all).
First few days, performance was below average, lag here and there but it was acceptable and it did go away after a day or so. Could be the tablet adjusting and syncing with the recently installed apps.
What I did find unusual though was the battery stats. It showed numbers (99013, 99023, 99033) processes which I am unfamiliar of. I tried googling it and searching on the xda forums about this but have not found any post on this. Is anyone else experiencing this? Is something wrong with my device? It could be the culprit to the overheating and battery drain.
(still trying to find out how to upload the screenshot, if anyone could help out with this, it would be much appreciated. PS: xda says that I have to make at least 10 posts before I can share external links, so I don't know how to make imageshack work here. Or I'll just make the 10 posts somehow.)

I am running Android 6.0 Marshmallow on my Nexus 9 build number MRA58N. Device is not rooted but the bootloader has been unlocked and I am running everything on stock. Clean fresh install about 5 days ago. I did face some trouble trying to root my tablet at first (boot loop) but instead I formatted and just reflashed the firmware clean using (flash-all).
First few days, performance was below average, lag here and there but it was acceptable and it did go away after a day or so. Could be the tablet adjusting and syncing with the recently installed apps.
What I did find unusual though was the battery stats. It showed numbers (99013, 99023, 99033) processes which I am unfamiliar of. I tried googling it and searching on the xda forums about this but have not found any post on this. Is anyone else experiencing this? Is something wrong with my device? It could be the culprit to the overheating and battery drain.

I've seen those numbers before, however not sure what they are either.
What type of battery are you seeing.
When I was on stock mra58n I was seeing around 4-5 hours screen on time and about 4-5 days overall time on. I thought that was pretty good. I only lose about 1-3% overnight so I could let it sit for quite awhile untouched and still have a charge.
I am now on PureNexus Android 6.0 ROM and seeing about the same but slightly better battery. I'm seeing 5.5-6 hours screen on time and 6-7 days overall time on.
This is with ElementalX kernel which I highly suggest.
How long have you had the tablet? I just got it on the HTC 40% of sale.
I recently have been having the same problem, as seen here: imgur DOTCOM /a/IMqFW, you can see the "99006" active, right now another has appeared with "99040". I saw these number a week or two ago. I've had my tablet since may or so. I posted on the reddit r/Nexus9 for help, someone suggested that it might be some sort of old application which left a few things behind when it was removed from the device. I don't really know what to think of this.
Hi,
I also observed a drastic battery drain and going to the "battery" section in settings, i found a weird "99040" thing with a black android robot icon, draining 16% of my battery.
I don't know how to remove this and I suspect this is malware or something related.
Does anyone know how I can remove that sh**** ???
Best regards.
I greet you all in the name of peace my fellow comrades.
4 days ago i joined you in the xiaomi smartphone race by buying xiaomi redmi note 3 pro. Everything was fine and nice till I found out the very first day that my phone suffers from huge battery drain overnight. I did my research about this matter already but was unable to find any clear and soul-soothing answer unfortunately, so I'd like to ask you if you could help me by sharing your experience and opinions with me.
I'm not going to pretend I'm not a hardcore noob in miui as it is my first xiaomi phone and generally flashing/rooting too since the last time i was flashing anything was like 4 years ago on my galaxy s1 i9000
So to make this post as short as possible:
I'm on stock OS - exactly as it came from the store - android v.: 5.1.1 LMY47V , security patch level 1.8.2016, miui v.:MIUI Global 8.0 | Stable 8.0.2.0(LHOMIDG) , CPU: hexa-core max 1,8GHz , no mi account yet, no unlocked bootloader, no root.
observation:
I downloaded cpu spy from google store. thanks to this app i came to know:
1- the phone never goes to deep sleep but stays on 691MHz or higher all the time.
2- after turning it off and on again, it can enter deep sleep for several hours. then I browse a little on wifi, check gmail and so on or whatever.. after some time, the phone usually doesn't get to deep sleep anymore.
- in battery use, android system and android are shown as the two major culprits (high percentage). When i click on the "android" process, high "keep awake" time is only present here. not in "android system"
cause?
D) Google Services? http://en.miui.com/thread-356299-5-1.html according to another guy, "they are working on a fix" -?
E) fingerprint wakelock? http://forum.xda-developers.com/redmi-note-3/development/kernel-t3414884 fix by flashing older modem - doesn't seem like my problem,. but what do i know right?
F) something else?
fix?
A) should i try to upgrade to 8.0.6.0.LHOMIDG | stable ? not sure, because miui forums are filled by users complaining about bad battery drain in this version.
B) Do i need to unlock it and get another ROM to solve this problem? According to this guy, changing ROM didn't help him https://www.reddit.com/r/Xiaomi/comments/5af17d/battery_drain_on_xrn3_pro/ i try to avoid flashing as long as possible
C) is there even a fix?
I already went through this guide, but it didn't solve the problem http://en.miui.com/thread-339815-1-1.html
I bought a new phone and expected it to be working right out of the box, instead I've been just googling and googling for the past 4 days to no avail. I'm really confused and desperate in this matter and don't think I'd be able to continue looking and find a fix to this problem just by myself.
What should i do? I have time till next week's Wednesday to return it back to the store for full refund... or should I return it right away without any hesitation?
Thank you in advance for your reaction.
I've had this phone for some months now, and with normal daily usage and a custom rom, I can make it 4-5 days with 1 charge which is nearly impossible with MIUI ROMs; from personal experience at least. If you do not want to upgrade/change your rom, I would suggest you unlock your bootloader and root your phone. After that you could try installing "Greenify" from Play Store which really helps hibernate apps. I've been using it for over a year and it makes my battery life last at least 2-3 days more with normal everyday use. If that doesn't help either, you could try installing a custom rom which generally is "lighter" compared to MIUI roms. Hope I helped, good luck.

MIUI doesn't need Greenify because it kills apps automatically by default. I use it on all my devices except my RN3P.
My suggestion would be to go into the permission manager first and disable everything but the non-essential functions. Next go to background permissions in Additional Settings and do the same. It took me a few weeks to get things working properly and now I average about 6-7 hours of sot.
I still have some apps that keep occasionally have long keep awakes but force stopping them brings them back to normal. For example a 30 minute keep awake from bbm will show as only 5% on the stats but will account for a full 10% per hour on it's own. I've now removed it from the whitelist and allowed miui to control it. Hope this helps.
