Greetings from (cloudy) Germany. Many battery problem threats exist in this forum and the world wide web. Unfortunately most of them reach hundreds of pages and after the 3rd or 4th page it slides away from any technical discussion and becomes very emotional. This is the reason why i´m going to open another one, which hopefully helps me. So here is my ....
... frame what happened:
I own a SGS2 GT-I9100, branding free. It´s almost half a year old. When i bourght it, it came with GB 2.3.4 which worked fine for me. At the beginning of this month i recived ICS via Kies. As a result of this update my phone became super slow. Almost all applications hung and chrashed. So i decited to manually go back to an older FW. I´ve choosen GB 2.3.5, as the look and feel was better for me, then 2.3.4.
... Problem:
Since i did the update to 4.0.3 my battery performance is 10 times worse in ->standby<- as it was with 2.3.4.
... what i did so for, to isolate the problem:
Many threads talk about an Android OS bug. After a long search it is still not clear to me, what this bug excatly means!?!? Apps, which drain the battery are not installed (there are no special Apps installed, except the ones which come with the FW). I have no widgets running and the phone is in Airplane mode. If is switch off the phones display i loose about 30% battery during one night (8 - 9 hours). With 2.3.4 it was about 3% per night. If i use my phone during the day (SMS, Calls, Wireless, 3G and music) it does not increase the battery usage very much. maybe 40% per 8 - 9 hours. I did a factory reset to my phone, installed cpu spy and switched the display off. Analysis show 99% Deep Sleep. nevertheless it uses 30% battery during this time.
In summary:
- German GB 2.3.4 got an update from K.I.E.S. to ICS 4.0.3 -> bad phone performance and battery drained
- Downgrade from German ICS 4.0.3 to German GB 2.3.5 following a procedure and firmware from android-galaxy dot info
- With GB 2.3.5 the performance returned back to normal but battery was still bad.
- Installed German GB following a procedure and firmware from android-galaxy dot info
- Performance was still good, but battery drained.
- Installed netherlands GB 2.3.5 and battery was still draining.
- Received ICS 4.0.3 via software update. Fortunately the phones performance is still very good but the battery drains anyway.
All test where performed without any app installed and in flight mode.
Questions:
1. what ist the so called Android OS bug in connection with battery problems?
2. does anybody have the same problem and solved it?
3. is there any way to recive the stock rom, which came with my phone?
-> a friend of mine have the same SGS2 with GB 2.3.4 and without any battery problem.
Thanks for constructive, helpfull and unemotional technical feedback. If you have further question, send me a PN. I´ll summarize them, and add them to this post. It will keep it clearly and in coherence.
Why not rename General forum Q&A then users wont break the rules .
1. what ist the so called Android OS bug in connection with battery problems?
No search ???? read the Android OS Bug Post .
2. does anybody have the same problem and solved it?
Long time ago Android 2.3.6 .
3. is there any way to recive the stock rom, which came with my phone?
YES if you know what it was and can search for it .

Stock Roms .and csc
http://forum.xda-developers.com/showthread.php?t=1075278
Thanks for your quick reply. I found many things for "Android OS Bug", also solutions. For example: "Disable widgets" or "stop wireless sharing". Unfortunately nothing helped me.
If you kow about the same problem with the battery and how to solve it, please tell me. I searched for it and was not successful.
I know the page for Stock Roms and how to apply them. As you can read in my initial post i did some up- and downgrades. I went back to official 2.3.4 with existing battery problem.
Maybe this was a missunderstanding. I need to know if ther is any "smart" way, without rooting etc., to get a rom out of an existing phone, without the battery drain.

Thx for your information.
My phone charges up to 100% (as far as it does not lie to me). ;-)
I do not complain about the power consumption. I complain about the difference between stock 2.3.4 and any ohter stock ROM / update i installed.

Have you tried any custom roms?
Or contacted the retailer about this?
Maybe it is a hw problem.
It would suggest a battery fault tbh.
Flashing repeatedly can put strain on the battery (from my own experience), also as far as I am aware, the official update via KIES did cause battery related issues; I never experienced, but my friends did, and Samsung UK where troubleshooting by, removing the battery for 10 minutes, letting it drain out when put back in the phone, then performing a full charge when switched off. If not resolved > factory reset - which did help one of my friends surprise, surprise lol.
If you are still in first 6 months I would advise contacting Samsung Germany for a replacement battery to see if any improvement. Otherwise you can buy cheap online.
Hey superthug & T__. Thx for your good comments. I´ll give it a try. One of my friends have a SGS2 without any problem. I´m going to x-change it with him.
Cheers.
Hey Guys. I made some further testing, but it´s getting more ande more worse.
1. I x-changed the battery with another SGS2. My battery is draining and the other SGS2 is good. -> No battery fault.
2. I did many factory resets, installed betterybatterystats, but it shows no wake locks. all values are below 4%
3. I installed cpu spy, and it shows 98% Deep sleep, when not using it <---- as expected!
4. I changed my FW to:
I9100XWLP7_I9100XXLPS_I9100XEULP5
ICS 4.0.3
Base: I9100XXLPS
Kernel: 3.0.15-i9100XWLP7-CL340913
[email protected]#3
Build: IML74K.XWLP7
All was downloaded from this Forum. I9100XWLP7_I9100XXLPS_I9100XEULP5 is the default, which came with KIES. I verified this with another SGS2, running this FW trouble free!
5. When i charging my SGS2 now, it heats up extremly. The CPU is running at 1Ghz while external power is connected (not only during charging)
Any ideas?
Hi,
I am seeing the same issue. I noticed after upgrading to ICS that the phone was working well for a few days and battery life was good, then after I plugged it in to charge overnight (as I always do) I found that the battery had decreased and the phone was hot to touch near where the camera is located on the back the following morning.
I reset the phone to defaults and I was able to charge a couple of times but this didn't fix the problem and it started happening again.
I have tried charging from my laptop, and 2 separate USB chargers with different cables and the same fault has occured.
A reset of the phone seems to temporarily fix the issue and I can charge the phone again but when I plug in again to charge I see the battery decreasing.
It seems as if something is screwing up and causing the CPU to run at 100% when the charger is attached which would explain why the phone is warm/hot to touch.
I'm just testing at the moment to see if I can get the phone to a state where the charger is connected and the battery is decreasing to try to identify the cause. I suspect that it may have something to do with when the phone goes to sleep and the screen turns off so I will try to set the timeout to 10 mintues to see if this helps and the battery starts to charge again.
Suspend Mode bug + linux power management regressions: flight/airplane drains battery
Hi, I experienced a similar issue with GS2 i9100G. I also haven't found a clear and definite answer in the various forums I have been digging into.
To sum it up here's what I found:
Android 2.3.4 worked perfectly fine with GS2, but upgrade to 2.3.6 introduced a suspend mode bug. Basically Suspend mode would cause the system to enter a loop, thus the battery drain while in flight mode.
The best solution would be to downgrade/stay with Android 2.3.4 (when it ain't broke don't fix it).
Possible workarounds if you'd rather not fiddle with your OS version:
Wifi settings > advanced settings > Policy: Wifi always on (so as not to trigger suspend mode with wifi), then (optional) use a Battery Manager App to fine-tune the wifi activation. Wifi always on drains your battery, but less than the system loop if you're not constantly on the move.
Don't use flight mode, shut you phone at night and use a good old clock) (and redirect calls to your landline if you must)
Try and find the apps that require regular sync thru wifi and might be the sole culprit causing the system to enter the loop
Note that Android 2.3.4 is based on Linux kernel 2.6.32 and that Android 2.3.6 is based on kernel 2.6.35 which introduced a major power management regression.
The fix for this regression has not been fixed before current kernel 3.3 (although some developer may have backported the fix into 3.2), so I would advise to stay away from current Android 4.0.3 ICS which is based on kernel 3.0 (later versions will be based on kernel 3.2 though)
I am not sure if this is the root for the suspend mode bug or if both issues are independent, but in the meantime 2.3.4 works perfectly fine.
EDIT: upgrade to 2.3.6 then 4.0.3 really stand as blunders from Samsung on such high-end Smarphones. Regardless of the device, waiting for the upcoming Android version 4.0.5 seems the better choice if you want to enjoy ICS and not regret iOS...
Android 4.0.3, a version with well-documented problems, including the battery problem, rather than 4.0.5, which solves many of those problems?
Probably not. Probably, the slow nature of Android updates is to blame. It took six months for version 4.0.3 to wend its way through the system, meaning it could yet be months more before the updated update, version 4.0.5, reaches users.
Right now, it seems their only option is to go back to 2.3.6, just like they’re asking.

Suspend Mode bug causing flight/airplane mode to drain battery
After trying different things I came to the conclusion that it all comes down to apps who force themselves to run in the background when you install them and request frequent syncs (free apps will do whatever it takes to boost their ad revenue).
To me it's still a bug in the suspend mode (Apps shouldn't be allowed to request a connection while in Airplane mode, doing it triggers a loop of failed attempts) and Samsung overlooked it.
In the meantime the previous solutions I mentioned do work:
n°1 (lazy fast) - Wifi settings > advanced settings > Policy: Wifi always on (so as not to trigger suspend mode with wifi), then (optional) use a Battery Manager App to fine-tune the wifi activation. Wifi always on drains your battery, but less than the system loop if you're not constantly on the move.
n°2 (depends on the number of apps) - Try and find the apps that require regular sync thru wifi and might be the sole culprit causing the system to enter the loop
n°3 (last resort) - Don't use flight mode, try to turn off data instead or shut you phone at night and use a good old clock) (and redirect calls to your landline if you must)

A battery calibration shouldn't be of much help.
Eventually I read someone, with Android ICS 4.0.3 installed, who mentioned DTIM and explained that changing the default 5ms to 1ms solved his battery life problem (note that you usually set this parameter to the highest possible latency to save your battery on mobile devices)
this is by far the most interesting battery problem thread i have found in the past 2 weeks. this exactly describes the problem I've been having.
initially nothing was wrong for me either. straight out of the box went ok for months. i'm not sure, but i think it was 2.3.4. shortly after the stock official update (unbranded) update to android 4.0.3 i noticed the battery died in about a day, instead of 2 days.
things i tried thus far:
- flash 2.3.6 back. same problem.
- flash 2.3.4 back, same problem.
- since it sucks either way, i flashed the stock 4.0.3 again.
- disabled a whole ****load of apps i normally use. same problem.
- decided to root and flash dragonICS 4.0.4 with default siyah kernel
- swapped battery with a colleague who does not have this problem. same problem.
- reset battery thingy in extweaks, battery % reporting sucks big time since then, but essentially: same problem
- tried a lot of suggested tweaks in extweaks which are supposedly better. same problem.
- set syncing at a longer interval (even though it worked fine out of the box). same problem.
- disabling all the sensors i could (including rotation for the apps), wifi, data traffic in general. same problem.
- cut the light sensor polling interval in half (from 1sec to 2sec). same problem
- removed the SD-card, because god knows what conflict it could cause. same problem.
- removed sim card, since problems were reported between this phone, android4 and my provider. same problem.
- full battery drain and charge cycle. same problem
problem verification:
- battery monitor widget, which logs an obvious higher battery usage than my colleagues phone.
- badass battery monitor which clearly shows "kernel" and "android system" way up there, where it should never be.
- "system tuner" in the "task manager" section which shows "android system" and "/system/bin/surfaceflinger" using the most cpu time by far
- "cpu spy" shows the cpu most of the time in deep sleep, which looks pretty good to me.
i can see the android system is using a lot of time reading 2 sensors, which seem required by basic functioning of the device. screen rotating and brightness.
i am unable to find out what the kernel is doing with all it's time. but whatever the rom, it's doing something.
ps: not all tests were in this order or seperated as they are described.
better battery stats shows a few processes on top:
kworker/0:3
kworker/0:1
kworker/0:0
kworker/0:2
in this order
It was a hardware fault! Samsung replaced the planar, ... now it´s fine. Thanks to all replys and your help.
while i'm happy there is a solution i am wondering about the following:
how can software introduce a hardware fault?
Hello, I have new LG P760. First thing, what I've done was update to Jelly Bean. But I experiences battery drain. Everytime, when I look at battery stats, there is Cell Standby on a first place and second or third is System Iddle. I've done hard reset and phone recovery in LG support tool. The problem is still here. Can it be hardware problem? Is there someone with experience like that? Sorry for my english
Exactly same for me. It happened after JB update. I found that device stays active even screen is locked when mobile data are on (battery stats app).
Conditions: factory reset after update, no additional apps installed
I hope just a bug and will be fixed soon.
Hello guys,
According to my experience, I think this is happening with you coz both of you flashed JB rom which is not for your country, there is no any solution to this problem until you got jb update for your own country.
I also faced same problem and got solved after update for my country (india).

Yeah I've noticed a increase in battery drain on my P769 running V20D.
On ICS my battery would last 2 to 4 days on average, but on JB I can barely get 2 days
Same here
I updated my phone via wi-fi with the official rom. And had the same problem. Battery drain. So i downgraded back to ics. I prefer battery life instead of project butter and google now.:good:
Now I'm just guessing, but it could be the google now app. Try shutting it off or don't allow the google location stuff.
Many were talking about the Google Now service which was a battery drainer. You should try and see the results. I also tried it,and the top 2 consumers were still Cell Standby and Phone Idle.
This thread might help with the battery drain. I think csrow found the problem

This is the same experience I'm having after the recent JB update on my P769. Battery life is now about half of what it was on ICS. Cell Standby at 35%, Phone idle 22%, Screen 20%, Wifi 11%..
Used to have plenty of juice mod/heavy use, was quite impressive. Now I have to carry a charger.
I too experienced crazy battery drains after upgrading to JellyBean (OTA update, P769 T-Mobile prepaid, pure stock, not rooted). I tried turning off Google Now after reading this thread, but it didn't seem like it helped much.
Last night we decided that my wife is going to use the phone instead, so I factory reset the phone before I gave it to her so she can start over fresh with her google accounts, etc. She left home this morning with the phone fully charged, and when I came home from work in the evening I checked and she had more than 85% left! Granted she didn't use it much throughout the day as she still carries her old phone, but she did use the phone to make some phone calls/chat and take some pictures. Just as a comparison, the last time I had the phone with me before the factory reset, the phone was draining battery maybe about 15%/hour just sitting on my desk.
So, for those of you experiencing battery drains, maybe you can try doing a factory reset if you haven't. I realize this is not something most people want to do unless it's guaranteed it will fix the problem, but if it's as annoying as my experience, maybe it's worth to try.

update: the wifi radio is always on change the setting as of csrows thread it is always on even if you dont have it clicked it has improved my battery some but much more is needed on alot of things im working on things ill update you all when i figure some things out
Just for those who don't know where this setting is:

Change "Keep Wi-Fi on during sleep" option to "only when plugged in" (or "never" if you want).
Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

Wow
Im glad the XEF update helped
Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
After months of waiting, finally update is rolled out in Nordic countries. IN this case, Sweden specifically.
I was so glad and excited, but few days after, only disappointment has left....
I have two Galaxy S6 Edge phones. One is mine and one from my fiancée. Both old 4 months, in perfect condition without signs of use. Both worked FLAWLESSLY on Android 5.1.1, and Android 6.0.1 ruined everything.
Two identical phones, only appearance differs, two different issues.
On my phone battery life is decreased by 80%, I cannot get a six hours with moderate usage, while I was getting 12 and more hours on Android 5.1.1. with same usage pattern. Last days, often I find it completely dead (within 6 hours since last charge), without enough juice to even flash!
What have I tried:
- Wipe cache
- Removed majority of apps
Nothing worked.
My fiancées phone have no issues with massive battery drain, but something even more annoying: If screen is left off for longer than 10 seconds, wakeup of phone is extremely slow:
- On first button press only touch keys flash for a moment. On second it MIGHT turn on with delay of aprox. 10 seconds while brightness is SLOWLY increasing. After wakeup, device is slow, until unlocked. After unlock, it work almost flawlessly except phone calls - Dialer is extremely slow, stops responding during the call, impossible to hangup the call. Before she is able to accept the call (nothing appears) there is delay of aprox. 5-15 seconds. Sometimes she even can't accept call at all!
What have I tried:
- Wipe cache
- Soft reset x3
- Hard reset x3
- Disable all animations in Developer menu.
- Thousands of reboots
Nothing worked.
From two perfect phones, we now have two average barely usable phones.
Any help? :crying:
Is it possible to downgrade(with Odin??) to Android 5.1.1 latest, without tripping Knox? Where I could find latest Android 5.1.1 Nordic?
Or even better - is it possible to fix any of those issues? Android 6.0.1 is great in almost all other ways.
Regards
You need to mess with the doze function. There are apps running when screen off and other things running in the background. You can limit these in the settings. I had this issue until i messed with that

You may also be experiencing incompatable data issues. If you try to factory reset backup all of your files in the internal storage and factory reset. When done that should fix some of the problems

I'm going to try. This is for my phone only, I guess? Not a fix for second phone.
Still do not restore with smart switch because it will hold the incompatable datat

At the end, nothing helped so I ended up by downgrading both phones to latest Android 5.1.1, and I can say that it's the best DOWNGRADE ever. "Upgrade" to Android 6.0.1 felt like downgrade....
There is nothing from 6.0.1 that I miss. On Android 5.1.1 battery lasts long again, and there is no performance issues. We're very happy again.
I'll post thread with detailed info how to downgrade because it took me long enough to figure that out with lack of tutorials.
after upgrading to marshmallow, my battery usage says 70-80% battery used over wifi. it seems kinda odd. cause screen should be the first on the list. can't post an image as um a new member here.
anyone else facing this after marshmallow update. seems like wifi is draining my battery. any way to fix this? plese someone help me out
Well, probably WiFi seems to drain your battery most because it is the most used feature in your phone. It shows the same on my phone in standby Stamina disabled, and it's likely draining 80% of 1% of battery per hour. Tested E2303 while I was sleeping.
Hi im from south america and when i flashed MM i took the customized usa one, yesterday i downloaded the generic LAM firmware and flashed ONLY modem, now seems to be working, or at least, i dont have the wifi taking the battery like before
go to setting > locaition > scanning > off wifi scan + blutooth scan ...
then go to setting > wifi > sett (WIFI ، keep WIFI on during sleep) on never ... restart your phone ... and enjoy MM ^_^
Wait for few days it stabilizes mine was 80% first day than 40% next and for few days it held but now it's 1%
So i thought it was fixed by reflashing modem, but the bug is still there.
I left the phone overnight with wifi off but lte data on, also wifi scanning in location off and it reports that wifi used most energy.Its not like a "drain" but it seems to be a bug in the report when you arent connected to a wifi network.
This bug and the battery icon that looks weird, annoys me a bit...
Had the same problem! I reflashed the phone with the nordic version instead of the greek that I had in the first place! This fixed it for me!
I flashed a dodgey MM firmware and had really crappy WiFi signal along with insane WiFi battery drain. I've given up flashing 6.0 for the time being (I'll see if an OTA arrives, still got my DRM keys) I just flashed LP so it's fine for me. Not really sure what you can do, if I flash Marshmallow and find a fix I'll be sure to tell you.

How do you flash the Modem on its own? Is it the same as creating a full FTF file but just selecting the Modem file?
You select the desired ftf in flashtool and before flasg you gotta exclude everything but modem in this case
Mee too at the first 2-3 boots wifi drained about 70% of the batterie but now it's about 5-10% so just wait
U said things r off in my phone also it's draining
