[Q] Do I have the Android OS battery bug (Dark Knight 3)

I really like the Dark Knight 3 ROM, but the battery is dying so quickly.
Last night I left it fully charged and 9 hours later after I woke up the battery was on 60%.
Wifi/GPS/Data/Sync = Off
Screen = auto
If I play with the phone for like 1 hour a day and the battery is dying on less than 12 hours.
The battery section shows Android OS as the biggest consumer, which the cooker of the ROM said is only a visual bug:
1. Android OS battery bug. Because i took the settings apk from akop4.0.3. So its just showing wrong.

Maybe I should switch to another ICS ROM

Give it a few full charge cycles for the battery to recalibrate.

Hm, never heard of that. Recalibrate in relation to ICS or in general?
Because the phone is not new and has been charged the fair amount of times.

Most of rom developers recommend few battery charging cycles, before conclusion.
Noting matter how old is the battery.
My OS Battery bug is drastically lowered after I disabled google search, talk, plus and maps.
Of course, GPS, Wifi and Data is default OFF, 2G ON.

the android os bug in case of ICS roms is in name only.. meaning that it just shows with highest usage in battery stats but doesn't actually cause battery drainage.. this problem has been fixed in 4.0.4 version of ICS..
so that means your battery is being drained by some other app.. and ofcourse as mentioned above, if you have just flashed a new rom, give it a few charge/discharge cycle time.. if still not satisfied you can always try some other rom ... though I think DKv4 beta will be up soon.. and this thing is taken care of in that version

Battery drain.. kernel (android os)

Hi everyone just got myself a HTC One and I've been experiencing quite bad battery life, usually start the day on full battery around 8am and by 4-5 it's dead or near enough, this seems quite bad for me since my iPhone with a much smaller battery lasted a lot longer, so I downloaded GSam battery monitor and something called kernel (android os) is taking 30% battery usage, is this normal or some kind of bug? I took some screenshots of the battery usage so if anyone could help me out or wants to see the screenshots please let me know, thanks
I've done a factory reset and also running stock version of android updated to latest firmware

[Q] EMERGENCY!!! BAttery draining like a rocket

CAn anyone suggest how to fix battery drain im on fxp Cm 12 02/09 and i turned everthing off and battery on low brightness.Also this happend before on other roms.NEEd a fix please reply fast:crying::crying:

What other ROM's did this happen on? Were they also Lollipop ROM's? I personally experienced this once on CM12, my phone went from 70-ish % to 1% overnight by doing absolutely nothing! My advice is to come back to Lollipop when it is more stable, it's way too buggy right now to be used as a daily driver IMO.

I have already implemented that guide it works for 5 mins and then starts again to drain. How much screen on time do you usually get.:crying::crying:

Have you switched back to KitKat yet? I noticed the battery going down a lot quicker on Lollipop myself.

i use stock jelly bean, and i get 5 hours screen time on average, sometimes i get 6h+

kitkat
Yes I'm on KitKat now crystalpa 8.50 that battery is still draining and how do you get 6hours battery screen on time on jellybean please explain the method thanks:crying::crying:

Same here with the battery. I returned to stock 4.3 to see will the problem remains.

i have been using one plus x charger since few days.. battery charges from 14% to 70% in around 30 minutes (with 3g onn!!)

What could be the problem for this? Few days ago i didn't have problems with battery and then suddenly yesterday morning it went to 50%, though i charged it at 100% the night before.

Please help !

guys i dont know wtf is this ...my phone battery is 100 when i shut it down and reboot it is 14 %..after another reboot it is 50%..and in a custom recovery while flashing a custom rom and during the first boot IT NEEDS MORE THAN 30 % ..it drains more thatn 15% just while flashing a ROM..(viper rom etc..)
now while normal using the battery doesnt drain like hell..it gives me 5 hours SOT or even 6 ..what i notice that my device is heating up like hell in nomral using (facebook messnger and facebook and whatsapp)NO BACKGROUND APPS RUNNING just these apps..
do you think i have a bad board ?or i have a dead battery ?

Hi TS, Im not an expert on any of this but what I suggest is to download and install an app to check you battery usage from full to atleast 10% to have a better look into things. It most likely that something is making your processor to run in full resulting in need of lot of juice and making your battery heating much.
Also as far as I understand, it can also be factored by the kernel you are using.
Again im no expert so please be guided accordingly.

Flashing ROMs and booting for the first time drains a lot and your phone heats like hell while updating apps. That's normal. Facebook mesenger and whatsapp are known to be really big battery drainers, and if they drain your battery, they heat up your phone too. If you can get 4-5 hours SOT on one charge, you don't have to worry about the state of your battery - it's good

my P9 is a battery sucker?

Guys, just asking for those already running EMUI 5 build on Huawei P9, have you guys face problem such as battery drain very fast? My P9 battery draining very fast until I have to charge OR bring my powerbank with me all the time. Is it the latest build caused the battery run fast? or there are something wrong with my phone?

Start by checking third party apps, my battery is great, it's the first phone I've had that I don't really think about charging, it gets through the day every day with heavy use.

don't use beta build if u are not willing to receive bugs

Check the battery logs for imonitor. I had high battery usage by this process - it may be that the beta has higher analytics so that's using more battery (and therefore should be fixed for full release).

Do you have root?
If you do, install that: http://www.onexuan.com/battery/
Or, pro version (you know what to do if you have root): http://www.opgpro.com/
If you don't have a root, play a bit with: Settings\Advanced Settings\Battery Manager\Protected Apps - Put "some" or all to sleep when screen is off...

Same here... Even with power saving mode enabled

Hi had issues with the battery on mine but I think it was down to being rooted and some other software that was on it. Since flashing it back to stock the battery life is so much better. Easily gets through a day now.

Can Phone Manager be silent battery killer? It closes all apps (except protected) when you turn off screen and you have to relaunch them again. I've read in multiple sources that you shouldn't be closing manually apps because in newer Androids RAM management is great and closing/opening again apps will consume more battery that just leaving them be?

P9 battery is damaged after 6 months here. Also a small spot appeared behind the back of my screen. Send it to warranty. They said the battery bloated inside and was pushing in the screen. Replaced both battery and screen. It seems there is a huge battery problem with all p9....

I'm running EMUI 4.1.1 and the battery drain is real.
Left it at 100% charge when I went to bed yesterday and when I woke up this morning battery percentage had already decreased by 12% (88% charge left). That's insane.
