[Q] Battery drain on Galaxy S with Teamhacksung Build 13

Hey guys,
I'm having trouble with the battery for my Galaxy S depleting really quickly (about 10% per hour).
I'm running ICS with teamhacksung's latest build (13) and platypus 3.08 NEO 3.0 kernel.
I thought initially that it was a kernel problem (I was running FUGU, which isn't on the preferred list of hacksung), so yesterday I wiped the whole thing, upgraded from build 12 to 13, flashed the kernel, wiped all of the caches and restarted.
The battery seemed fine and it decreased about 10% in 8 hours on standby, which is more than acceptable.
Then I was wokenup at 5 am by the phone telling me it needed charging (it had dropped 70%+ charge in 5 hours). By looking at the battery stats (attached below) it says that 70% of the battery is drawn by the OS, upon closer inspection it seems as though the system is draining when it becomes actives, and it looks as though it's becoming active on a regular interval. I thought this might be due to Appkiller, but I've since disabled it and it still seems to be draining pretty quickly.
The only other thing I can think of is that when I receive an email or sms, the settings and back buttons light up and stay on. Could that be the drain?
Anyone have an idea?
Thanks a mil
Cheers
Paul

Update: Swype to blame
Hi guys, I think I've solved it. If I don't post here again then I am right.
The problem is Swype. I installed it on ICS and it works great, but when I try to download additional languages, it seems to get stuck in a loop of attempting to download and failing. This results in the phone constantly being on and never going to sleep more which depletes the battery in a matter of hours, and of more than 170mb of mobile data raked up in a couple of days.
I haven't reinstalled Swype yet, I want to see if the battery lasts today before I do, but I will try to reinstall it without the additional languages and see if it works like that.
Cheers
Paul

Yes, confirmed, it was the installation of additional Languages in Swype.
Cheers

Thanks a lot for your question + solution. Using devil 1.1 kernel and Teamhacksung build v16 I had exactly the same problems. Now I removed Swype, which didn't want to download the Dutch language pack anyway.

One X Gets Hot without use and battery life tanks

I've been noticing less than stellar battery life ever since I got my One X.
Lately I have noticed that sometimes my One X will get slightly hot under use(around the camera area), and then after I'm done using it, it still hot and my battery drains like crazy.
I turn the screen off, kill all apps, wait 5, 10, 30 minutes, even one hour I have waited, and the phone is still warm!
I don't use any apps that run in the background or have services that use a lot of battery. I've checked logcat, betterbatterystats, Cpu Spy and can't find anything wrong. I've tried different roms and the same thing happens.
The fix is simple. I just power it off and on and the problem goes away for a few hours, but then comes back! When I power it off, the area gets ice cold in less than 3 minutes , which tells me something is going on.
I can't figure out a pattern to trigger it but it seems to happen most when my phone switches to WiFi from LTE or vice versa.
Has anyone noticed this? It's been incredibly frustrating.
-----------------------------------------------------
After months and months the problem has been found and resolved. It was due to an LTE bug that would happen in certain areas(such as subway stations) if you lost all signal and then regained. The phone would get warm and battery would drop significantly, as much as 2% per minute. The drain would not stop until a full restart.
After trying many many roms, and after about a month testing it, this one has the problem fixed. I haven't tested other ROMS and quite frankly it works so well that I didn't bother testing for other ROMs.

I have this problem too. I put mine to sleep, after waking up from an hour nap the darn thing is hot! And of course the battery drained like crazy. Although it's too early to come to a conclusion, but so far it hasn't happened ever since I turned off autosync and wifi every time I take a nap..

Run betterbatterystats and carat, they can all identify various issues.

My phone does not deep sleep at all. Wtf?

I'm having the same problem, carat and bbs aren't helping

See if there are rouge apps running in the background that are keeping the phone from deep sleeping.

Go to Settings -> Wifi -> Advanced -> Best Wi-Fi Performance and make sure it's unchecked. It's been known to prevent deep sleep. I'm not sure it would cause such a huge drop in life or the heat, but every little bit helps.

Glad to know I'm not the only one experiencing this. I'm an advanced user, I've tried everything, carat, BetterBatteryStats, aLogcat, System Panel, Cpu spy, you name it. The phone is actually deep sleeping.
Also, I've noticed that the radio area gets hot more than the cpu area, so it might be a radio issue? I'm running baseband 0.17.32.09.12_10.86.32.08U .

I'm on 0.17.32.09.12_10.86.32.08L (same as you, except for the L). I noticed that you mentioned that it may be when you're switching between WiFi and LTE, maybe it's continuing to hold on to that LTE connection? Also, where is the radio area in relation to the CPU? I know the CPU is right underneath the camera.

What is the difference between the L and the U? I've never flashed any radios so I guess I'm using the stock one from the 1.85 update.
I actually just assumed it's the radio because I was testing a cpu stress app to see if it would get "locked" in a high frequency thus causing the drain, but the area that got hot was to left of the camera area, and usually when the problem happens I can sense the warmth more to the right, around the LED flash.
I just charged my phone to 100% and it got warm, I unplugged it and waited a few minutes and the phone was still hot. I turned the phone off and in a matter of minutes (Like 4) , the phone was ice cold again. The plot thickens...

I don't know what the difference is. I'm running CleanROM DE so it could be that the L is just the radio from 1.88. I never had this heat issue on 1.73, 82, or 85 though. Just the normal amount that threatens to burn your hand off while playing Angry Birds. Maybe try disabling LTE? (Don't ask me how to do that)

Disabling LTE (By changing the APN settings) , makes my 4G(Non-LTE) connection unstable, for some reason. I experience a ton of data drops , so even if fixes the heat problem, it would create a new one. My data connection is rock solid when using the LTE APN .

I'm running stock 1.85 and the battery is great

I had a similar problem before until I installed CleanROM LE 2.0 (and above) I noticed the problem when I connected to wifi after I had lost signal from my commute every day. BBS didn't really help, and it seemed the problem would compound over time, eventually getting to a point where I was losing 3% battery ever couple of minutes.
After I installed the Lite Edition, the problem hasn't appeared since. Battery life seems to be draining normally and the phone doesn't get hot when not in use. It could be something that was removed from Sense that helped the issue, but I'm honestly not sure.
I do remember that before I switched to the Lite edition I tinkered with some settings, and I noticed that Latitude was set to update my location. I turned it off (it's off by default on the Lite Edition ROM), but I'm not sure if that helped my problem. Maybe try disabling that and see what happens.

Wow,I have a very similar usage pattern. I will try that and report back

Can anyone chime in on the difference between the L and the U in the radios?
Sent from my HTC One X using XDA

There's a thread with flashable versions of all the known radios floating about...There's nothing with a U in it except the Asian radio, but the rest of the baseband version number doesn't match.

He fixed that now so even the Asian version apparently ends with an L. Does that mean I have an unkown baseband? doubtful. I have installed sick sense hox and so far so good. We'll see.

deep sleep and warm back.
I've noticed this, too.
I've woken up in the middle of the night to encounter my screen on and no gain in battery charge with a super warm back.
Last night I plugged it up at 73% and I woke up this morning with 71% and a fry-an-egg-hot back.
Restarting resolves the issue, and this is only the second timein about 1.5 months, but a concerning issue nonetheless.

Blame calendar sync
I had the exact same problem, and I narrowed it down to auto-sync.
In particular, my phone was constantly sync'ing my work calendar (my work place uses Google calendar/mail). I have a lot of recurring (weekly) events on that calendar, and one of those events was modified shortly before the sync started acting crazy.
How I fixed it:
1. Go into Settings > Apps > All
For "Calendar" and "Calendar Storage" apps, press the "Clear Data" button.
2. Removed my work Google account and re-added it.
Obviously, if it's not the sync that's causing the battery drain or you don't have any calendars synced, then this is not going to fix anything. Just thought I'd share my particular case with everyone.

[Q] Cell Standby / Phone Idle Drain - Embryo 3.2 / UCLE2 / Cymbaline 1.5

Hey Guys,
Let me start by saying that I've spent the better part of 3 days searching XDA, google, reading various other forums for answers to my problem before I decided to post this. Even if the answer was close, or for a different phone I tried all the recommendations to no avail.
I recently just got into the whole rooting and flashing thing. I first tried cyanogenmod9 nightly, and then Embryo 3.2 which I immediately fell in love with. When I flashed, I followed the instructions step by step - wiped all the data, cache, dalvik, formatted then did it all again. Everything is working without a problem. My issue is that cell standby and phone idle is absolutely crushing my battery. I went from getting 17+ hours of normal use with room to spare before charging for the night to barely getting through a day of work.
I installed better batter stats, badass battery monitor, and as a last ditch effort juice defender - hoping that if I let it control the radios and have them off it would curb the problem. Juice defender checks my emails n' all once an hour and it's no help at all. I've burned up almost 20% in 4 hours and i haven't even touched my phone except to see if JD was actually working. Badass battery monitor shows the radio as the biggest drain, and better battery stats... well, frankly, the info it reports is WAY over my head..
My phone is a fresh install of Embryo 3.2, UCLE2 radio, and cymbaline 1.5 kernal. I'm running go launcher, beautiful widgets for time/weather, and go contacts widget. That's it. I read about the phone idle, charged it to 100%, cleared the battery stats in CWM trying to calibrate it and it seems to have done nothing.
Also, I understand the radio works different for everyone. I think my issue is that if UCLE2 is from 2.3.6 OTA, which is what I was using post root/rom, and what i'm currently using now.. why is it a problem now vrs before?
Should I just download all the available radios for the skyrocket, and try a new one every few days to see which works better?
I'm really just seeking a comprehensive answer to my problem which I can't seem to find anywhere. I wouldn't have posted this if I didn't believe I exhausted all my available options. sorry for the wall of text and thanks for taking the time to help!

It's very obvious that many, many people have this problem, but everyone tries to tell you to battery saving tips that just help to cope with the problem but don't fix it at all.
UCLE2 is not from 2.3.6, it's from the second most recent 4.0.4 leak, by the way. I don't really think this is a radio issue, though I did notice I have a problem in UCLF3 and UCLD2 Odin, but not in UCLE2 or Gingerbread. I'm convinced it's something to do with how these ROMs are flashed. I'm going to try CWM to UCLF3 from UCLE2 and see how that goes.

Yea, please let me know what you find. I'll try a new radio when I get home. I'm not going to bother trying to flash a new rom, or this one over again as i've already done it multiple times - the issue has not changes...
cell standby, phone idle..

Get rid of jd first. It makes ics worse. In fact better battery stats is the only "battery assistance" you should keep. Then reflash everything. If you restore with titanium backup, don't restore system data. You'll have to re enter your email accounts and stuff but your contacts should sync once you do. And every time you flash a new ROM it needs a few days to settle. It will burn extra battery in those few days. And I don't know how go contacts widget works, but it may have some interaction with the phone apk that mohan hasn't engineered for, keeping it awake. I'd go without it for awhile too and see if that helps.
Also get CPU spy. To see if your phone's getting any sleep. You could be having some kind of wake lock. Reboot when you pull it off the charger.

I think it is in part a wake lock problem, however rebooting after taking it off the charger doesn't help.

New radio won't change that. Unless you're not using the one mohan provides in the embryo thread. Something is bugging out the phone apk. You may want to try embryo 3.2 without the cymbaline kernel also, and see if that's any better.
Also I should say again, whatever is causing your drain problem, jd is making it worse.
Anything that might be keeping the phone awake. Maybe a Bluetooth or like I mentioned, possibly the go contacts widget.

Alright, thanks.
I've done as you suggested and will report back.
I've installed BBS and CPUSpy. (I don't know how to read bbs, so perhaps point out some things i should keep an eye on would help.. )
I've removed juice defender, go contact widget, and badass battery monitor. I'm pretty much stock except for go launcher ex and beautiful widgets for time/weather.
I'll also remove and reset the battery cache in CWM
When i get home tonight i'll re-wipe/format etc etc and start from scratch again... *pout* lol

Yep, thanks for the info. I won't change the radio, and i'll keep using whats in mohans embryo thread. I'll re-flash and leave off the kernal (which, i like because when i talk on phone it doesn't get hot like it used too).
I removed JD, contacts widget, and everything else except data is off.
What specifically should I be looking for under CPUSpy and BBS
THe phone has currently been on for an hour and 50 minutes
spu spy states deep sleep of 80% for 1:26:28
and bbs under "other" reports 69.4% for both no or unknown signal and no data connection for 1hr and 16 min both

No, don't do any of that and don't reset the battery cache in cwm. This might be your problem actually. When you reset battery in cwm you essentially make a new 100% mark. Like, if you do that when you're at fifty percent battery, you just cut your Max battery life in half. So do THIS when you get home. Turn the brightness all he way up. Download angry birds or something and play it until your phone is dead dead DEAD. Then plug your phone to the OEM charger. The one that has a USB plug on the wall end. Let it charge all the way when it's turned off. Then when you turn it back on, hold power and volumes and go straight to recovery. That's the correct time to reset your battery cache in cwm.

Keep everything the way you have it now and do he charger thing. If you're at&t. If you're rogers change to ruxlf3 radio. Actually trying a different radio may not be a bad idea but give each one a day to see how it does. See if that "no or unknown signal" in bbs changes. You aren't having wake locks. Deep sleep is what you're looking for in cpuspy. I think jd turning on and off the data and searching for a new signal caused a lot of the burn so far. Are you in an LTE area? The other thing to do is make sure your apn (settings > more > mobile networks > access point names) matches what is listed in the embryo thread. Keep your kernel and don't reflash anything except a radio. Try ruxlf3 or u...f5 tomorrow.

I'm in AT&T and I work smack dab in the middle of an LTE area with good signal.
I live 60 mi from work, in a non LTE area but still have good signal.
My apn settings were actually set by the phone when i received a call straight after flashing. Att PTA - internet + mms, i'll check mohans thread and see what's up there.
THanks a lot for your help, I really appreciate it.

Ok, I've had some luck getting normal-ish battery life (~15 hours). Still seems a little below what it should be and performance is also slightly sluggish compared to stock, but it's clearly miles better than the dead in 7 hours life I was getting.
Now, I don't know if I just got lucky finally or if any of this actually helped, but here's what I did:
* Flashed UCLE2 with Odin.
* Ran battery all the way down
* Charged battery all the way up with phone off. Unplugged it, left it off, and recharged it a few times.
* Wiped battery stats
* Odin flash CWM (NON-TOUCH version this time)
* Darxide Superwipe (x2)
* Flash CM9, Gapps
* Boot
* Darxide Superwipe again
* Flash CM9, gapps again
* Boot, drain battery all the way down
* Charge battery all the way up while phone is off.
Again, not saying this is a fix just saying what I did in as much detail as possible in case it helps anyone.

just go download embryo 4.0 fast and stable.

Rogers SII battery issues - radio the cause?

I have an issue I’m trying to resolve on my Roger’s SII.
I’m running aokp milestone 6 with instigatorx’s kernel v4.0b and everything was running nice and smooth without issues. But I wasn’t getting the best signal so I updated my radio.
I updated my radio to the Roger’s stock ICS radio from the Embryo 4.1 post (http://forum.xda-developers.com/showthread.php?t=1754473) and have noticed a huge decrease in battery life (basically watch the battery percentage tick down). I also noticed my phone is now getting really warm to the touch.
I flashed the Roger’s stock ICS radio from Seanzscreams and same issue.
I flashed back to the GB radio in the Embryo post and same issue.
So I’m not sure what I screwed up but it’s annoying when you’re phone won’t last a day or even ½ day.
Anyone have any suggestions?
I’ll keep searching in the meantime for a solution….
Thanks.
**EDIT**
Turning on Airplane Mode stops the phone from discharging rapidly and my battery stats indicate that Phone is consuming the most power. Not sure if that helps.

Can MB1/MF1 Firmware Kill Battery Life?

I've been running Synergy/Ziggy combo for a while now and recently noticed I'd drop network connection while still being able to do regular phone stuff (text/call). I discovered I was running KT1 or some other older baseband and figured I'd throw on MF1 with an AIO zip install. After figuring out a workaround to getting the camera to work I was psyched as 4g lte was coming in strong and speeds seemed to have resumed their regular pace.
Problem is that I've noticed my battery life has pretty much crapped the bed now. I used to ride to work with Pandora playing with wired headphones and noticed I'd get to work with about 95%+ battery life. By the time I was at work, it showed high 80s. With very minimal use by lunch time I was showing down to the high/mid 60% mark where I'm still usually at around 70-80% with random facebooking, texting and instagram stuff. None of which I really did as I wanted to see whether the battery death was in my imagination.
Anyone else notice issues with battery life after flashing new firmware? Is it possible my phone's still working out which towers to lock onto with the new antenna?

Look at your battery stats, if android system is at the top, then you need to do more investigating. I would fix permissions and or flash the kernel again to start.
