4.1.2 and battery

Hey guys
I recently upgraded to 4.1.2 and it's been causing a lot of battery drain.
Googleplay magazine app was taking about 28%,so I disabled it and now "Android system" is doing the same thing. I also have disabled GPS/location services and google now but it hasn't changed.
Any tips?

You CAN NOT do anything to reduce Android System usage. So if no app is causing major wakelocks and it's Android System only then you can't do anything but to bear it.

Yes, we only can wait for upgrade from Samsung... with 4.1.1 I had excellent battery, overnight with airplane mode, I hade like 1% drain, max 2%. Now I have like 10-20% !!!!! But I was afraid of Sudden Death Syndrome so I upgraded....

maybe can solved about ur battery issue

Nah, this rarel helps, I tried while I had Desire HD, and nothing helped. It is similar now with Note 2. It is simply OS that is causing it, not an app. The only thing that changed is android, all other apps are the same.....

Thanks but I already know what's causing the battery drain I just don't know how to fix it.
Update: I disabled google sync and things got a little better,but still worse than 4.1.1

If you have a powerful device, expect battery to drain fast unless you do battery saving tips. But for me I bought this beast to maximize its potential so its ok for me if battery drains... thats why it has a removable battery compared to the norms now which is non replaceable ones...

I know but with 4.1.1 I experienced much better battery life w/same usage.
Anyway,I reset back to factory settings and still,the "android system" is eating a lot of battery so I guess I have to revert back to 4.1.1 :/

[Q] SGW I8150 drain battery very very fast after i flashed it with CM-10.1 alpha6

i just flashed my samsung galaxy wonder to have CM-10.1 alpha6 a few days ago. and i realised that it drain battery very fast.. just simply fully charge it to 100% and left there with wifi,bluetooth and all applications off, yet the battery drained in half day..
if open 3G, the battery drain 30% in 20 minutes.
can sumeone tell me what's the problem and how can i solve it? thx a lots

Why don't you try to flash another kernel..
I personally recommend kernel by hurtsky, or by castagnaIT.
that's only my opinion..
you're welcome to try..

first, how old is your battery?
older than 1 yr, u should try getting a new battery.
mine was 1.4 yr old, battery drain when play game lasted 5 mins from fully charge to zero.

Well..
It's just the same way like how you flashed the cm10.1 rom..
Try to head to this page:
http://forum.xda-developers.com/showthread.php?t=2218087
There's also an instruction on a proper way to flash it..
And don't forget to thanks him if you like his kernel

CM10.1 aka Android 4.2.2 uses higher voltage compared to CM10 and CM9(especially CM9).
So its understandable. But in CM10.1, SGW can use 1.0Ghz and still fluently do a lot of things.
Try underclocking and undervolting.

I have CM 10.2 everythings is ok..battery consumption is depends from life time of your battery then the number of apps and services activated...

Change to new battery
hmmm.... maybe it's because of your battery.. from my experience , you should buy new battery if the battery is used more than 1 year... i had experinced before when my battery drain faster, after i bought new battery.. the problem solved...

Guys. Stop telling him it´s the battery. If it were the battery the draining would be already that fast before flashing CM10.1, but not just after.
A bloated and aged battery can of course be the reason, but this doesn´t have to be always the case. My stock Samsung battery is already 2 years old but working like new. However I have to admit that I don´t use it that often. Having here 3 batteries I´m changing them regulary every few months.
This draining will be more related to the LCD version in his phone, which he should read about and check before flashing a CM10.1 based rom. Additionally the recent Google updates can cause even more battery drain than the LCD Rev.3 issue alone, which has to be taken also into account.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?

Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.

Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...

Will be an app causing your phone to wake

I dont know...i searched on the web and someone said that stock kernel have some problems

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?

I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...

You have problems with motherboard. Go to service center to replace it on waranty.
Powered by CM12.1

But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!

Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.
Powered by CM12.1

How long does yours battery last with some normal usage?

Almost 3 days with moderate usage.

Woww thats a very big difference haha.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.

Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!

chances are that it won't be even 2000 mah.. it is best if said capacity is actual capacity. try and share feedback. more over battery drain issue. did you performed a factory reset after updating?? i would suggest you to flash latest raw firmware. after first startup. go back to recovery and factory reset and use and see if battery still drains fast. after that buy new battery

I have the same situation. Had to update the software using Odin. But the battery did not return to normal.

Elaborate.. what did you do?

Check which apps are consuming battery.
One time I had Settings system app consuming 40% battery. The problem with Device Care is it doesn't show system app consumption.
Best thing to do is go to
Apps > show system apps > then click on system apps you suspect.
Scroll down App Info and check the "battery % used" section.
The thing that caused my high battery consumption was to do with a system app I disabled using ADB.
