[Q] Extreme Battery Drain From Wifi Wakelock [CM12.1] - Sony Xperia Z Ultra

So I'm having some trouble with all the cm12.1 builds for togari so far,
they drain the battery so fast that the phone is nearly unusable.
I've done some looking around and it seams like the problems I'm seeing are "kernel wakelocks",
so can I solve it somehow or do I have to wait for cyanogen devs to find a fix?
CPU stats from system monitor:
Wifi vs No Wifi
Deep sleep 55% vs 88%
2,2GHz 37% vs 3,4%
Discharge sph 8% vs 1%
Kernel wakelocks on wifi(source: BetterBattertStats):
PowerManagerService.Wakelocks 15,2%
qcom_rx_wakelock 9,4%
event1-786 8,8%
event0-786 8,7%

Same here, drains about 30-40% of battery in 1 hour. Gets really hot. Im on SlimLP 5.1.1 by omar.
got it to work by wiping cache and dalvik. But still drains more than normal.
Charging the battery is slow, 5% in 1h with 1,4A 4,95v charging current.

Have you tried a wakelock detector app to research what's keeping it awake?

[Q] Battery life normal?

Hi guys,
I'm using GingerMod v0.3 with the default kernel (ninphetamine 2.1.3).
My battery was at 100% when i went to sleep. After about 8 hours when i woke up, it dropped to 92%. Is that normal?
I have turned off automatic sync as well as gps. Even "Back up my data" and "Automatic restore" was off. Display was at a minimum 3%. Most of the battery % was used up by Android OS.
given the percentage of the draining 8% over 8 hours i quess is pretty good. I quess different rom + kernel produce different effects. Yours is considered ok.
ya the drain is quite normal

1% an hour during sleep mode is considered good? i had the impression that it would only drop 3-4% during sleep.

More than good I'd say. And you never can have a constant rate, one night it will be 3-4%, other night it will be 9-10%, depends on the processes running at that period. If you have Better Battery Stats installed then you will be able to see what had cost that extra drainage under Partial Wakelocks section.
I normally have 3-4% drain in an overnight period of 8-9 hours, but yesterday it was 15%. Then I saw it was Camera360 Ultimate which was running and searching for GPS!
Regards.
That's about similar to what i get on standby with data enabled so yeah good battery there/
Thats good ? Mine drops 1 percent overnight (+-10 hours) with original battery Or stays at 100 until morning when I wake up with 2000mah bat... Data and wifi turned off.
But I presume thats just me being battery friendly user
I tried better battery stats and it seems the Email app is consuming the most resources during sleep. hmm...

battery drain while sleeping

last 3 nights I noticed huge battery drain, about 1% per hour, anybody knows where is the problem?
my tab runs stock ICS rom and stock kernel
thanks for help
after some diagnostics I found that GoogleServicesFramework is battery drainer (not sure, it has most wakelocks in betterbatterystats - about 50 in 5 hours and its awake time is about 1:30)
Try the OsiMood ROM http://forum.xda-developers.com/showthread.php?t=1677281. I previously was very disappointed in battery life, but after switching to OsiMood battery life is much much better - especially in sleep mode. Overnight unplugged it drops only 1-2%.
I downloaded autostarts and disabled startup of GSF on every event and left only Application Installed event (if disabled, market wont download any app)...seems that battery life is back to normal...99% at the morning (no keep awake time in battery stats) so it is fixed without changing rom , I did this procedure also on my phone and its battery drain during night is greatly reduced

I9100 battery voltage inaccurate/fluctuating. Tried common fixes. Help?

Good day,
I have a I9100 w/ ResurrectionRemix V3.1.3 and Siyah-Dorimanx Kernel V7.34 on Android 4.2.1. I have been using the rom for a few months already but over the last 2 weeks, there has been severe idle battery drain. 11-15%/hr on idle, more if I actually used the phone.
I have tried calibrating my battery (full charge, drain till 0% and re charge). Also tried resetting fuel gauge chip using STweaks. One thing I noticed though, is that when I go to Testing page (dialler > *#*#4636#*#*), the battery voltage fluctuates. After fully charging my phone and turning it on, it states about 3900mv instead of close to 4200mv. Then it continues to be erratic, for example from 3800 to 3960 to 3870 etc. Is this the cause of my severe battery drain and how do I fix this?
Currently battery is at 79% but 3853mv.

Dude,Resurrection Remix is an old ROM,updated last year.Try to find a newer one,like JellyBam 7.8.0.It Android 4.2.2.Also,update Kernel to DorimanX 9.21.These are the latest ones.I'm running these too,and my battery drain is only 6-7 %/hour.
Battery is on the way out. New battery. Losing capacity is a sign of a dying battery.
I have tried 3 different ROMs and 2 batteries. Using Jellybam 7.80 now. All have the same issue. None of them have had better battery life. For example, I can have 70% deep sleep and a discharge rate of 15%/hr. Not long ago I was having 3%/hr at 70% deep sleep. I only use whatsapp mostly. No social networking apps due to their frequent updating.
This leads me to think that it is more likely a hardware fault. Does a faulty charging port PCB result in this problem?
I will post the BetterBatteryStats page of my current charge after 5hrs of idle soon.

[Q] Resurrection Remix 5.0.3 Battery Drain

Just did the Update from the v5.0.2.1 to the latest version and now all of a sudden "Android System" drains my Battery even at night. I couldnt find any other thread mentioning this problem.
Using 42% of battery it has CPU total of 1h 1m 11s and Keep awake for 5h 35n 29s
While "Second place" goes to the screen with just 12% of battery.
Kernel is 3.0.64-CM-g6763764 by westcrip.
I honestly have no clue what I should do.. Had no battery issues with the 5.0.2.1, battery lasting for almost 2 days...
...to maybe rephrase my question: has anyone any idea on how to stop "Android OS" from keeping my device awake and/or stop it from sending/receiving data (because those activities must be the ones draining battery).
When I block "Keep device awake" in the privacy settings the phone reboots from time to time which gets quite annoying.
Thx!

LG G2 battery drain in Deep Sleep - No Wakelocks

This has been happening for a week now. My phone drains battery like 8-10% per hour. I have Wakelock detector and Better Battery Stats. They show almost no wakelocks. wakelocks are at 5%, the rest of the time it is sleeping. I'm on Cloudy G3 last version.
When using it non stop from 100% to like 5%, my phone lasts the same as before (3h - 3h30m, brightness at 80%), the problem is sleeping.
I tried Shutting Down, new kernel, unninstalling the apps I downloaded last 2 weeks, and now I flashed CyanogenMod 11 M12. This happens on CM too.
Any solutions? Is there something wrong with the battery, my phone?
Screenshots attached.
Thank you.
