[Q] SGS2 ICS 4.0.3 battery issue - Galaxy S II Q&A, Help & Troubleshooting

So last week I upgraded my Samsung Galaxy S2 from GB 2.3.3 to ICS 4.0.3 via kies. My battery life was pretty terrible after that so I did a factory reset by going into settings and doing it from there. The battery life improved a bit. Its good when I'm not using it, but as soon as I start using it the battery goes down about 1-2% per minute, which drains the battery really fast. I've already re-calibrated the battery but I dont know if I did it right. It was at about 40%, I turned it off, plugged it in until 100%, then unplugged it and took the battery out for 3 mins and put it back in, which I dont think really did anything. Was I supposed to let the battery drain completely? I've seen some people say thats bad and some people say it's okay so I'm kind of confused. I've also been trying to wipe the cache but I havent figured out how to do it. I've done the whole vol up + home + power but it takes me into a downloading screen that stays there until I have to take the battery out to reset it. I have all the stock equipment on my phone (I've seen people mention rooting/roms/kernels but I have no clue what those are). My screen is at the lowest brightness setting but still seems to eat about 45% of my battery with a black background, with android OS around 30-40%., everything is set to unsync, all emails are set to get mail manually, and data and wifi are off unless being used.
Is there anything else I can do to improve the battery?

Look, we already have a million battery topics so dont really need any more. Use search and go read some of them for advice and solutions, you're not special and your issue is not unique.

[Q] Telus fascinate serious battery drain HELP!!!!!

Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

3h 25m left
Screen 55%
Cell Standby 9%
SystemUI 7%

Android System 7%
Its defiantly got something wrong as even though it says 56% if I unplug it, it will die in about 10 min. Even with a fully charged battery it does the same. Yes i also waited until 100% and wiped batt stats and at 3% left wiped stats. Screen is in standby

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

Need Help With GSB v2.4

Hello everyone! I would have posted this in the actual GSB thread but I don't seem to have the correct privileges yet so I am posting here instead.
First off, I just want to thank workshed for his awesome work. I really do love the ROM and everything about it. However, I have a few small issues with it that I can't seem to figure out.
First off, my battery life is terrible. Take yesterday for example. I used my phone probably twice to send some texts in the morning and to check the time. Charged it throughout the night and pulled it off the charger when I woke up and began my day. Within two hours, my phones battery was down to 75%. Five hours later, it was completely dead and I hadn't even used it.
My second issue is with settings. For some reason, when I reboot, some of my setting don't get saved. The one thing that really bothers me is the keyboard. I have Swype installed and every time the phone shuts off, I have to go into settings and re-enable Swype as my keyboard. It is just a hassle and is kind of frustrating, especially when I forget to do and then go to send a message.
Other than those two issues, I absolutely love the ROM and wouldn't change it for anything else. Anyone have any suggestions for what I can do about my few issues?

Recharge it until you get a green light. Restart the phone in Recovery, go to the Wipe menu, and wipe the battery stats (I'd keep the phone on power for this.) Restart the phone, pull the power and use as you normally would. Ignore anybody who tells you that you must run the battery down until the phone shuts itself off - this is really not great for the battery (though once a month or so isn't bad), and really isn't necessary for the battery calculations to reset themselves with new usage stats. The longer you can go the better, but it's not necessary to change your phone usage habits so that you have a completely discharged phone.

Thank you for that information, I shall try it out and see if it helps!
I also forget to mention one more error. Whenever I boot up the phone, my Facebook account sets itself to not sync and I lose all my contact pictures. I then have to open the Facebook application and set it to sync again.
EDIT:
Sorry, didn't realize it was a double post!
My battery life is similar to the OP's. I can make it through the day, but since I am ususally down to about 60% by one or two pm (from 6 or 7 am) I prefer a mid-day charge just to make sure I can last through the evening.
I just flashed [ROM][3/22/2011] GSB v2.2 | GingerBread 2.3.3 [CM7.0.0 RC2 NIGHTLY] a few days ago and it has been running great, but I noticed that my green light (battery fully charged) now comes on @ 90%.
Before it would not turn from amber to green till 100%. Should I wipe battery stats?
Under battery use (sry no screenies) there is nothing unusual:
Display @57%, everything else under 10%.
But when I checked Spare Parts I noticed that my little Eris won't sleep!
It looks like Android system is the culprit, keeping a partial wake lock.
Battery History in Spare Parts:
Other Usage - Since last unplugged
Running 100%
Screen on 13.2%
Wifi on 100%
Wifi running 91.6%
Partial wake usage - Since last unplugged
Android System almost a full blue bar, all other apps minimal bars
The phone has more or less been sitting at my desk at work in wifi with light usage.
Anyone have any idea why Android System is trying to eat my battery?
i had battery problems on gsb its a great rom. i switch to ginger tazz. with tazz's rom i get more then 20hrs b4 it says to connect charger thats with the display on about 4 hours and wifi on and running facebook tapatalk calls texts and whatever i think of doing.
I'm running GSB 2.5 CM RC 4 and I now have been able to get 25 hours with 70% of battery left. I used to be able to get maybe 24 hours before it died. Now your mileage may vary but this is what I do. I removed Task Killer which was eating a bunch or the battery and after a visit to Amazon's app market their little app was running all the time along with Weather Bug so both of them are now gone. and finally I turned off auto sync ( I can check my email when ever I want and it takes a lot less battery). By turning off auto sync that was what really made the difference for me. Of course there are many things you can do but running WiFi will kill your battery faster than 3g (or at least it does on mine) and I have the screen brightness set at 18. Just a note I leave BT and GPS on all the time when they are not being used an are in standby their usage is quit small.
What works for you would depend on if you want your email pushed to you all the time and if you have to have your WiFi on instead of 3g.
Again it's just my observations for my phone.
Really you should just do the first suggestion and recalibrate your battery.
Also if you read closely in workshed's log, he specifically said to a full wipe not only formatting external memory but also doing a dalvik/cache wipe. You may as well also wipe the battery stats while you're at it.
Personally I'm running GSB 2.5 and it's simply amazing. 60% of the battery gets me from wake-up alarm to nighttime charge.
Hope you figure it out!
After I installed GSB 2.5, my battery also seems to be rapidly discharging. Takes less than an hour of no use, wifi-on to drop from 100% to ~80%. I did a full discharge calibration on my battery as soon as I flashed to this GSB 2.5
I will attempt the simple batt stat wipe at 100% and see if that helps at all. I'll let you guys know.

[Q] Any one else have this weird battery drain?

I got my galaxy s2 (international version) about 4 months ago. Recently I've noticed some weird battery drain mostly when I restart my phone, but it happens other times just out of the blue.
It might be a software bug not showing the proper battery level, but I've attached pictures that show normal battery drain even after that jump down. Obviously, if it was a a software fault the battery percentage should remain level or go up slightly. (Yes the battery level does go up a bit, but I lose significantly more battery than I gain.)
This has happened in many instances and I've only got a screenshot of two. Sometimes I get big discharge and at other times its small. It's pretty annoying when you think you've got enough battery and go out, only to find the phones dropped 20-30% out of nowhere.
My phone is unlocked and not branded (bought from carphone warehouse UK- CPW). It's running stock XXKI4 firmware (2.3.4) and I'm not rooted.
So my question is, has anyone else seen this happen or have I got a faulty battery? Is there a fix?
Hi there,
Battery drain is one one the main argouments you can find in this forums. ATM I'm in your same condition: after latets ROM ugrade (I've got latest CheckROM release), my phone "sucks" al lot more battery than before.
A lot of things could affect this: themes, skin, kernel, application bug, bad battery checking and so on. There isn't a valid answer... I think you must indagate on yourself, comparing what you find with forum's infos!!
Good luck!!

There are several threads about battery drain.
For example here => http://forum.xda-developers.com/showthread.php?p=16973603
Maybe you find a useful tip.
You have always test it on your phone under your conditions.
You can try to flash special (Custom) ROMs and kernels, which are optimized for better battery life, but as there are so many different influences on battery life, it is nearly impossible to find a general "fix" for all users and phones.
Good luck!
well at least yours lasts 15 hours, mine lasts at most 10 hours on heavy usage.
P.S. I am using 2.3.5
As to Anwser to those "drops" or "gaps" in the graph, just recently i noticed that my phone was working normally, i was monitoring its battery drain (i have a thread going on about it), and after some time of no using, after class, i noticed that my phone asks for my SIM PIN again, and is in Safe Mode (i dont really know what that it). When i checked the battery monitoring graph (battery info) i notice the absolutr same fall (from 70% to 40%), but i remember that i saw and used my phone at 60-50% too ! So i can only assume that the phone crashes, eighter reboots for some reason, and the data isnt saved (for example it saves the data every 2 hours or so), so there appears the "gap".
Thats simply my opinion, but i do remember using the phone at the % between the two extremes (IN the gap), so i guess the data wasnt saved.
EDIT: Ha! I'll add some pis now to show you guys this: so in my current history i have two gaps, one big, and one smaller before. So, the first time, i turned off the phone and PULLED OUT THE BATTERY aswell cause i wanted to check my batteries mAh (its 1650 but thats offtopic). Thats how the small gap appeared ! As for the big one, my phone seemed to crash and reboot while i didnt notice, because in an hour or so of no using i woke it up and it asked for the SIM PIN.
So there, i think the phone eighter crashes or doesnt manages to save the battery data, and those gaps ("falls") appear.

[Q] Battery Drain Problem

Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.
Sent from my GT-I9000 using xda premium
Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

try to reduce screen brightness it might help, and when on wifi turn off data plan might help too

Since you didn't seem to realize, I thought I'd tell you. This thread was 5 months old before you posted in it...

[Q] Stairstep battery drain

My wife and I both have the Galaxy S4, verizon flavor.
My phone's battery usage is very nice. Most of the time I go to bed with 30-70% left on the battery. Hers does the same. The only difference is I use my phone a lot and she barely uses it during the day. A couple of texts, maybe a phone call and on occasion an internet search. Before this happened, and I don't know what was the tipping point, she use to charge her phone every third day, now she charges it every night.
Her phone is also 6 months newer than mine. Both are running stock, both are Android 4.3. I have both phones setup as close as possible so I can make comparisons between the two. Obviously she has different needs and will have different apps running/installed.
I have taken all of her apps off the phone and it hasn't changed the battery problem. I have reset the phone and still the battery drain persists.
I have put Battery Monitor Widget and GSam on her phone and I really haven't been able to locate the offending app/program/function. The only possibility is the 1013 system and "AudioOut_2". But that seems unlikely as this drain is about every 20 minutes and goes on all day.
Usually she runs with her phone in minimal activity. Data off, Sync off, GPS off, Power Saving on.
Here is a chart from a while back, everyday looks similar with the drains. My phone has long periods of straight white lines when inactive, hers just keep going down.
can't post the image of the battery chart. Gonna make it more difficult to solve.
Just wondering where to look and if this is something that can be solved or is possibly a phone problem/defect. As I mentioned, mine works nice and I have it setup as close to my phone as possible to get results that can be compared.
first of all im no expert, but i think it could go either way. before assuming its hardware it wouldnt hurt to back everything up, try a factory reset and a wipe mk2 odin flash. then seeing if the issue persists. just throwing my thoughts out there. hope it gets resolved regardless. :good:

Have you tried Better Battery Stats + a Wakelock Detector? Between those two it should be really easy to see if this is a software problem or perhaps a bad battery.
I'll link you to the wakelock detector I use. In my opinion it's the easiest to use.

You can see wakelocks in BBS as well.... But I just like the options this one gives

I haven't tried BBS+, but Wakelock Detector has been running since the problem was detected. That is how I found the 1013 and Audio2_Out running. At the beginning it seemed to correlate with the problem but as time moved on it seemed less and less the culprit.
I haven't really found anything using wakelock detector. I could give you some stats off of it tonight when I have access to my wife's phone again.
Any stats that you'd like me to post I can do that. Eventually I'll be able to post that Battery Monitor Widget graph so you can see what is happening.
Pretty sure we can rule out a bad battery. About 99.9% sure.
First things first I would swap batteries between the two phones. Lets rule out a faulty battery first, because trying to figure out battery drain with a faulty battery can be maddening!

OK, all day with swapped batteries. Same thing. My phone is fine, her's is still doing the same stair step battery drain.
