New ICS UK official release battery drain

Manually upgraded over stock non rootable CarPhone Warehouse GB rom using PC Odin.
Im getting very bad batrery drain. On the stock GB rom my phone would easily last two days with moderate use. Now with the ICS rom its draining pretty fast. I took it off the charger approximately 1.5 hours ago and with little to no use Im already at 90%. Same stock settings and same apps. Only difference is I am now using Apex Launcher.
I noticed wifi constantly on even during deep sleep but i have now configured it to only be on while plugged in.
Ive pulled he battery out for a few minutes and that hasnt helped. One last thing im going to try is revert back to GB and then wipe, clear cache and upgrade again...
Any advice/help would be appreciated..

I´ve had the same wifi problem, german stock ICS though, weird enought it seems to happen just with my home´s router. I´ve checked in other places and all was fine. A couple of users here changed their routers seemed to solve the issue. See if this is of any help....

My note seems fine, have you tried the fix below.

Also try to find ways to analyse your battery usage, enough posts on that here
Cpuspy for deepsleep
Betterbatterystats for whats keeping phone awake
Android sucks in providing the info you really need up front.

Yeah, i updated to the lpy ROM when it was released and found the lack of deep sleep issue causing a problem. The above fix sorted it and I've had no problems since, performance has been noticeably better and battery life has been just as good, if not slightly better, than under ginger bread

Takes longer to analyse bro.
In those 24 min abnormal battery drain?
Best to check battery percentages.
Next to these two apps you can check badassmonitor or equavalent, they have also good measuring for actual battery usage per app.
Analysing sucks thought, totally not user friendly.

I could be wrong but it seems as if my wifi is still constantly active...battery drain is pretty bad...i think im going to revert back to GB, perform a full wipe and cache cleane and re install...

I did an "factory data reset" before and straight after i upgraded to the official UK ICS.
I did read if you use the alarm clock, it keeps your phone awake, even after you disable it, other apps most likely do the same.
Below is a picture over night, I always manually enable/disable wifi/bluetooth/gps as have yet to find an app that works correctly.
John.

Yeah tipically you would be looking for the following:
If your device goes into deepsleep at all. (on battery that is)
You can check this with cpu spy.
If it doesnt check the kernel wakeloks (high level) and the partial wakeloks (zoomed into detail level, best level for troubleshooting).
Anything there that runs often and long is probably causing the deepsleep insomnia. I wish Android would be better in able to determine what really influences your phones battery.
Next to this, some apps you can change synch settings (within apps itself, e.g. facebook etc) Thats just a typical change. every sync uses energy, and wakes up device.
Another possible check is the power on of with airplane mode.
Another tip is unchecking the sounds when touching touchscreen (a bug from the old days of android, and they never fixed) this is a major wakelock causer and by default turned on.
I usually get 4~5 hours nonstop onscreen time after tweaking it (without setting to much stuff of, otherwise I could have gotten a normal phone lmao)

after factory reset and data wipe on your galaxy note please calibrate the battery both ways...horizontal and gyroscope.
This will definitely help your phone better monitor the battery and bring it to normal status..

I tried out the steps mentioned in above link and I think its working for me.
After upgrading my note to UK ICS release the battery is drainig like anything.
Its like 1% every minute .
After applying steps mentioned in the url its not draining that much. MAy after some more recharge cycles it will be more stable.

Galaxy note over heating (System UI hogging CPU)

Hi,
I've a G-Note running ICS-4.0.3 , i recently noticed my phone is getting really hot and resetting automatically at times, on closer investigation i see 'CPU spy' data showing my phone running constantly at 1400Mhz mode!!! wanting to find which process is doing this, i downloaded watchdog lite and noticed that 'System UI' process is running at 49% approx CONSTANTLY, killing it re-spwans the process!! any idea whats causing this?? Please Help!!
Not rooted, never flashed, on original upgrade, have nova launcher, use it rarely. no other launchers installed.
Restart fixes this sometimes, sometimes not.
Thanks in advance,
Ramgo.

Not that i can think of as a problem, been happening for a while now, could be any of the app! i have like 200 installed!!
Now its not system UI, its android syste, badass battery monitor shows kenel to have taken most of the battery (which seems mostly loop task, is this bad) and then android core process.

well try to remember from which app on this issue showed up.I had battery drain problem turned out it was because of an app that I had installed.So I unistalled it and my problem went away.Yours should be easy to spot try unistalling the recent apps or the ones you're suspicious of and see when you get deepsleep.

Check your battery status and see for the battery eater apps

I infact got deep sleep the whole day, 15 hrs just 10 percent drained! this problem has been occuring intermittently, deep sleep is still happenning, but when the phone is screen ON, its in the highest mode.

Hmm things got complicated.Like I said if everything used to be normal then all of a sudden this problem began then it should be an app I suppose?!Just like my case.
Install OS Monitor and see what's hogging your cpu maybe you can pinpoint the application if that's the case.

did anybody have a problem with Gsam battery monitor after it was upgraded from Badass battery monitor??? i was looking at it and was showing 100% battery drain due to application ( 0% for screen and phone radio)!! i have uninstalled it and seems fine i guess! atleast for now! charging now and its in the expected 200Mhz state.

Yes will do that!! Thanks! read my comment below, i think GSam Battery monitor submits some task or makes some query to the kernel which makes it to go in a loop, hence the android system seems to be using more CPU and not battery monitor itself

The problem is back!! HELP!!
I checked OS monitor, nothing seem to be hogging, occasionally android system, overhearting near the camera and resetting automatically, please HELP!!!

Hello,
I'm having a similar problem. When my Note is in standby sometimes it overheats without any apparent reason and battery drains very fast.
I haven't been able to trace the origin of this problem. I'm running on ICS 4.0.3 stock and no ROOT.

Have you installed any kind of launcher on your phone? If you have, do try to uninstall it for now. Install BetterBatteryStats, turn off any data connection.. 3G, Wifi, Bluetooth.. Remove any Live wallpapers(just use a static one), Uninstall any apps that connect or syncs online.
The last thing I could advice you is turn off Airplane Mode (at night), charge up your phone to 100% and just leave it for a day. Check back on BetterBatteryStats after on what apps/wakelocks is triggering the overheating.

Lot's of work... I'll have to find some time to try all of that.
Thanks.

Early last week my Note started to reboot whitout any apparent reason. It happened 2 to 3 times a day. Specially in the morning when battery was still above 60%.
The overheating also happened from time to time but not everyday.
Saturday I figured I had to do something extreme to end this.
First I downgraded to a pre-rooted GB rom. Afterwards wiped the GB rom. Then upgraded to stock ICS. Everything worked out fine and was very easy to perform, thanks to all the guides available on XDA.
Last of all I rooted the ICS.
Until now the Note hasn't overheated or rebooted again.
I really thought it would be harder to do all this. But now I think it would take me about 20 min to do all these procedures.
Thanks to all the people that posted the guides on XDA.

I'll take that as a joke.
Three days in and still no unwanted reboots or overheating.

Gents if you have nothing constructive to provide in assisting the users with real help, please refrain from off topic mindless humor. Thank you.

A week after I've re-flashed ICS on my Note, the unwanted reboots have come back.
It must be some app I've installed again or maybe something much worse. I've read lots of threads and was wondering if a custom kernel and a different ROM might solve this problem.
One thing I've noted, the reboots never happen at night only during the day (mid-morning and mid-afternoon).
Any new ideas to help me find the source of this problem?
EDIT:
I'm running on LPY Kernel, so wipe is not an option...

[Q] How can I tell what's eating my battery?

About a week ago, I started noticing that my phone battery gets very hot and the battery drains quickly when the phone is NOT in use (Screen off, sitting on my desk). Full charge to 0% in 4 four hours or so, without being stressed.
When I try to charge it from the supplied wall charger, it doesn't get past 87% charged before the battery temp creeps into the 40s and it starts draining (while still plugged in).
I assume it's a faulty battery, only because I haven't downloaded anything new. The only change I made was updating Viber. I removed that app from my phone but it's still dropping like a fly.
I've done a factory reset twice, no change.
Rebooted the phone many times, no change.
Tried different cables and different chargers (PC, Old X10), no change.
Now, since I can't replace the battery in this phone, I'm hoping there's a software method to see what might be eating the battery.
Note : My LT30a .195 can't be rooted, and the bootloader can't be unlocked. Also, I don't know how to take screenshots.
Anyone have an suggestions ??

In Settings-Battery you should be able to see what processes are using it.
If you want to monitor cpu load in real time, then you'll need some app, like OS Monitor to see load per process, or PowerTutor for logging cumulative consumption.

I bought this phone several days before. Yesterday got root, installed cwm recovery and installed jb 4.1.2 deoxed stock Rom. I noticed that my phone can't sleep. Totally! Take a look on screenshots. I thought that may be bcoz of some apps so I wiped everything (int and ext sdcard too), but it makes no sense

Turning off your auto sync when not needed should do the trick.

Something's wrong there. I've got too much battery consumption by Android System too, but that is ridiculous.
¿Have you tried BetterBatteryStats to see what's keeping it on?.

AudioOut_2 is related to any games or apps related to sound or which "produce" sound..are you on stock rom and stock kernel?
try to exit any music player app after listening or exit the game properly after playing..sometimes keystrock sound causes it..
do one thing...reboot it and keep it idle for an hr or so..and while rebooting make sure your phone is not in silent or vibrate mode..and after an ar check the batterystats and let us know!
And do check all the columns including partial wakelocks and try to find which process used more time or percentage...

Dude your phone is just fine...10% down in 9 hrs with wifi on is too good...everything looks normal..gtalk seems to be waking up the phone to update the online offline lists.in general syncing...thats all..if it was 10% down in 1 hr then it wouldve been a problem...the data looks just fine..and trust me your phone is entering sleep mode..or else it wouldve showed different result..to confirm that install cpuspy..it will say what all frequency are being used and how much phone is sleeping and all...
so just chill..

[Q] V20A Battery.

I'm kind of worried of my battery life..
Last night was my first dissapointment, I left my phone untouched for the whole night (8-9 hours) and something just sucked away about 30% of my battery. Not sure if it just didn't go in Deep Sleep or bloatware leeches that much energy off it.
Within 4 hours of which not even 1 hour of Data usage + WhatsApp/Facebook another 30% just went away.
My battery was not this bad on ICS, specially if I left it during the night, I'd see max 5% drained.
Is this normal for now? Untill I go trought a bit of full rechanrging cycles? (From >5% till 100%)
Or it would be better if sometime I root it and remove some of the bloatware and convert system apps to user ones? (Like Maps,)

I also also less battery life. Is I have the double of the consumption in comparison With ICS . It dont have 1 day of battery life (18h), and I don't play. It's unsustainable...
Sent from my LG-P880 using xda app-developers app

I noticed that last night (after upgrading) I lost about 10% battery over seven hours, usually I'd only lose 4 or 5%. A little worrying. Google Now is turned off etc, just data, 3G and sync was enabled (just like I used to have with ICS).
I've just backed up my phone and might try a factory reset and restore to see if that fixes it.
I have noticed that if I open CPU Spy and reset the timers, then lock my phone and wait a minute, it is spending a fair bit of time with the CPU at 475mhz. I used to get deep sleep for 90+ % of the time, with 4.1 it seems to deep sleep about 60% of the time.
I'm gonna see if I can figure out what's waking it.
Did either of you do a factory reset after updating?
EDIT: Did a factory reset, installed BBS and CPU Spy, and a quick test found it in deep sleep 87% of the time. Currently restoring using the LG backup app, we'll see if that sorts it or whether there's something else going on here. Will report back with my findings.
EDIT: Ok, LG's restore tool just finished restoring the backup. It worked fine, aside from warning me about possible problems from a 'cross version restore', even though I made the restore with the same firmware version. As a side note, that LG restore tool is SLOOOW! I have a few big games but it would have been faster to set everything up manually, haha. Probably 2-3 hours it took to restore, though it was hassle-free.
Phone seems to be sleeping much better now... a few tests with CPU spy show about 92% of the time spent in deep sleep, which is about what I'd get on ICS. It's early days but if you guys want to give it a shot, it's shown some promise.

I just checked my phone battery stats and saw this:
Where you see the huge battery drain that's where I was downloading and then testing NFS (had better results than on ICS btw)
Battery was on 40% so I closed everything, even WiFi and went to sleep (7-8 hours)
If you see the stats it did went into Deep Sleep in the beginning but something woke it up and kept draining the battery.

I wish they could build a CM10 ROM with OptimusUI... I really like the visuals.

I cant say I am pleased with battery life on JB. I only had it for one day but it drains faster than ICS. Through the night,in about 10 hours,no wifi,no sync,no 3g,fast rebooted it drained 15%!On ICS,in that period of time, it would drain 3-4% max...On CPU Spy, "deep sleep" is only 33% so something is draining the batt..Anyone else with this probl?

Another update... I started having my phone only deep sleep for about 60% of the time again... and I think I have figured out why. Go to Google Maps, go into settings and check that "Report from this device" is unticked! Mine had somehow been enabled and I am fairly sure it was responsible for my deep sleep issue.

I was experiencing the same high drain overnight until I stumbled upon a thread on here which suggested deleting the maps apk and odex file from the system/app folder using a root explorer. you can then reinstall it from the market. I also did the same with chrome.
before I checked with BBS and maps location services were waking the system up constantly, but after doing the above things are much much better.
you can also try disabling MLT in the hidden menu 3845#*880# as there's a thread in general suggesting this logging app could be eating into battery life/ performance.

Is it normal that the battery drain overnight is over 10% in 7-8h ?

My battery life is very poor..Over the night it drained 30%!!! And I killed all the apps, wifi, 3G everything... Through CPU Spy I can see that my phone doesnt go in deep sleep(only 13%) and it is working on 51MHz for 76% of time!! And I`m not even touching it,the screen is off...Whats up with that?How can I fix it?
P.S. I disabled Google Maps because I heard that they consume a lot of battery in the background..

Either use BetterBatteryStats (which is available free for XDA members, search the forum), or Wakelock Detector. To use either of them, plug in your phone and let it charge up. Open BBS, it will create a reference state. Then unplug your phone and let it sit overnight. In the morning open either application and it will show all the wakelocks (times at which the processor was prevented from deep sleeping). Look at what's keeping the phone awake, and remove/disable it.

New HTC One battery problem

The phone was bought 2 weeks ago and I have battery problems after 2-3 days. So the battery drain is huge, i got 10% (100%-90&) after 6 hours with the phone idle no use at all. What can I do?
Sent from my HTC One using XDA Free mobile app

Mine (bought on March 2014) with power saver on goes from 100% to 96% in one night (data, Wi-Fi are off). I think that is normal. Battery lasts 2 days normal use (not much screen on).
You can do a Factory reset. Don't install apps and watch if the drain is still there.
1. If the drain disappear install your apps one by one to see witch cause the drain.
2. If the drain is still there send it to service you have a battery problem.

Did you installed some apps that may cause?
Is this brand new or used phone you bought?

need a bit more info.
go to settings - power - usage, and look at the app usage. You should see the typical apps you use a lot, but also look for apps that look out of place. like an app you don't use much, but uses a lot of battery use.
also look at settings - more - data usage, and scroll down. That will show which apps are using the most data, and also if it's foreground or background data. Don't worry too much about foreground data, that is data use happening while you are using the app. Instead, look for apps that are using a lot of background data. if you click on the app, you have an option to disable background data for those apps.
Note some apps don't function properly without background data enabled, like some google services/play store. also make sure the play store options are set to never auto update.
fwiw, I usually get 2.5-3 days between charges with light use.

Sounds like a major issue

If the phone is that brand new, it could be a malfunctioning phone that eats through battery life. I would try taking it back to where ever you bought it from and try getting a new phone. See if that helps. Otherwise you may need to purchase a different battery from a reputable seller in order to get a good amount of battery life.
Cheers!

You could try GSam Battery Monitor (dowload it form Play Store). It gives you a report on which apps drain your battery.

Those should be on the top of your list. You might have a faulty battery then. Have you tried a factory reset?

So, I tried a factory reset but still battery drain. I have another HTC One, with heavier usage and still goes all the day with 30-40% left at night. I will talk to Vodafone to sent the phone to warranty but I think they will say It's because you unlocked the bootloader, put a custom rom, and there is a chance to lose my warranty. Probably I'll buy a battery case

You could Greenify the apps running on the background. That way, they will only be running when you open them and not after you close them. This could help too.
