[Q] Android 4.4.2 - Android System use arround 60% battery

Hello,
I updated my Mini to KitKat 4.4.2 and I am experiencing battery drain issue. Android System takes arround 60% of battery and I feel, that my batter last shorter time as before update.
I did factory reset after update.
Is there anything what can I do?
Thanks in advance.

I had this problem too, but my usage was around 75% and would loose battery % every 5 minutes while the screen was off. Try using Tr1gg3r's stock rom listed in the developer section. There are 3 different versions. One of them will likely work better for you.

thank you very much for your answer and suggestion. I never put custom rom into any of my android device, but I feel now is the time

You'll find that the ROMs I suggested are pretty much stock, so it won't a jarring change.

Latest Software still causing battery drain?

I have read on various forums that the latest software update has been causing problematic battery drain on the M8 and more often the Verizon version. I briefly had one about a month ago but had to return it due to some contract issues. Now I am looking to get another as I really liked it. I did however notice that the battery did drain pretty fast when I had mine. It had the latest 4.4.2 software on it. If I root it, can I install an older ROM and have the great battery life return? Are there any tips on what was causing the issue? I see AT&T actually pulled the Kitkat update due to battery issues several months ago.
Thanks for the info,
Rob

No battery drain on my device. I'm on all stock Verizon and I did a factory reset after the 4.4.4 update. Battery life is excellent and I get through a 24 hr work shift with about 20 percent battery left, about 3 hrs SOT. I'm sure you can get an older ROM version by asking in the thread of the ROM you choose if it isn't available in the OP. Many fine folks here keep old copies. Good luck buddy!

Thanks I appreciate the reply.

The oldest ROM it originally came with is 4.4.2 so I don't know how much that would help your case. Maybe the newest 4.4.4 can help if you still have problems on 4.4.2 on your new phone (if it isn't 4.4.4 already)

I've had the phone since release date and never had a battery drain issue. The battery life was great at launch and has gotten a bit better with firmware releases.

Before I had the M8 I had a Gnex. On that Gnex android 4.4.4 would cause the phone to get very warm and increased battery drain. It doesn't surprise me that it does it on the M8 as well.

I didn't see any battery drain on 4.4.2, 4.4.3, or 4.4.4.

Pfft with all the ROMs out and kernels to help who needs battery drain.
HTC One M8

After the update, my battery life dropped by an honest 50%.
I dont use my phone much and used to get 6 days on a charge, now I only get 3.
I realize that's more than most and I should not complain, but still.
I also had to reset my phone due to problems with pictures in my previously recieved texts not opening.
The reset obviously did not help my battery problem.

6 days per charge? Haha what?

It's true, I'm older & only use a phone to make calls, & a few texts.
No social media stuff or anything like that, all Forum stuff is done on a tablet or computer.

serious battery drain with screen on

Hi all!
i got a oneplus one since about a week but i'm facing a serious battery drain problem. I bought my phone used with 5 months of life and used only a few times so its conditions are like brand new. When i first got the phone i installed cm12.1 nightlies but two or three days ago i switched to the last version of cm12s. Anyway, in both cases i have the same problem:
When i use the phone with the screen on the battery level lowers so fast, about 1% per 1 minute and half. During sleep instead drain seems to be normal. I don't have so much app installed and i usually take blocked with servicely or greenify the ones with services that i don't use often. Also have auto brightness to medium levels and i do normal use (generally navigation on chrome since this morning, no games at all).
Anyway, plugged off this morning at 9:00, now at 14:00 i have 20% of charge with 1 hour and 35 minutes of SOT.
The old owner told me that he didn't use the phone for about 2 months before selling it, so i'm trying to recalibrate the battery (discharge until it turns off, then charge to 100% with phone turned off), but situation doesn't seems to get better. Do you know if it is a well known problem or it is an hardware fault? Can you help me?
Thank you in advance and sorry if my english is not perfect

Have you tried other custom rom? What about stock ROM? If all ROM gives you similar issues, how about your firmware? Is it up to date? If all this doesn't work, you might have a faulty battery :silly:

Hi Bobbi, thank you for your answer! I tried cm12.1 nightlies for one or two days before and I had similar problems. Isn't the cyanogen 12s actually the stock rom for this phone? And what you mean with updating the firmware? I have downloaded cm12s here in xda, wiped all and then flashed it, isn't in this way all up to date?

CM12s and OxygenOS are both considered the stock ROM of this device (I guess ) but some others (like mine) comes shipped with ColorOS as the stock rom
But nonetheless and that aside, flashing CM12s and updating the firmware is a bit different. Most ROM doesn't pack with firmware except for OxygenOS and CM12.1 nightlies

Lollipop AOSP Battery Life

I've had 0,3-0,5% battery drain per hour (in standby) on stock 4.3 Jelly Bean. After update to KitKat, my battery started to drain faster and it was somewhere around 1,0-1,5%/h so I downgraded back to the Jelly Bean and all was normal again. Now, I updated to 5.1.1 AOSP Lollipop and even with everything off and all battery friendly settings, I'm experiencing exactly the same issue: 1,0-1,5% battery drain/h. I've made a new record with 14,5 days of battery life with light use (on 4.3) and now it's not possible to go over 4-5 days in IDLE ! I've made a factory reset/wiped everything. How is it possible that Lollipop causes me this battery drain when Jelly Bean didn't do it ?
I monitored my battery with wakelock detectors for 3 days but there is no wakelocks and device is (as apps said) in deepsleep most of the time.
Any suggestions ? I like new system but with this terrible battery life it's really annoying.

Terrible battery life would be less than 10-12 hours for me with mixed use. What do you use your smartphone (more like pocket computer nowadays) for anyway? 14 days of standby probably means not touching it at all, so why bother switching it on?

lp make more use of battery and processor , the only thing that I can do, to got a good time of battery is turn off all animations , in the OP you say "AOSP" you use a rom? the last build of alberto have battery drain , y recomend aosparadox is really cool

@davider222
I also want a great battery life. Do you know where can I download Android 4.3 for Moto G ? Beacuse I can't find any .zip costum ROM or Motorola ROM.

@Eurofighter_ty
you can't downgrade from 5.1 bootloader to older 4.3 bootloader because you will probably hardbrick your device but here are some links from xda

All KitKat and Lollipop firmwares
@STR4NG3R-GUY
I have 20150909 version, it's also impacted by battery drain ? I have just tested GPS and it consumed only 13% of battery during 6 h long bicycle trip so I'm experiencing only stand by battery drain, normal use is probably fine

@davider222
if you have that issues , why stay in lollipop ?, downgrade to kitkat :3

Should I upgrade from KitKat?

Hello all. I have been using rooted but stock KitKat for quite awhile now because everyone has always said it's the most stable ROM to use. Lately, however, my OPO's screen has been dimming but not completely turning off (it just sits in a dimmed state) and draining the battery. Also, it has been randomly rebooting, and WiFI says it's on but never seems to connect unless I completely turn off my mobile data (e.g. LTE). Looking at GSAM for the battery problem, it seems that the "android system" is the culprit. I have looked also used Logcat Extreme, but admittedly, don't know enough to recognize a major issue.
I know that Marshmallow still has kinks in it and Lollipop has been somewhat abandoned (in favor of Marshmallow), but are most of the major issues worked out? There's no point in my opinion of changing Android versions if I'm only swapping major issues for other major issues. However, I also fear that as Android moves forward, then apps will need to adjust and render some of the apps less compatible with KitKat.
I would like to have a fairly stable and battery friendly ROM, that has very minor, if any, issues. Does Lollipop or Marshmallow fall into that category? Should I upgrade to Lollipop or Marshmallow (or any related ROMs)?
Thanks for any and all thoughts and info.

Short answer: find a different KitKat rom. Slimkat for example.
Long answer: mobile radio active bug plagues all roms from lollipop and upwards so your battery life will suffer if you use mobile data a lot. There is no fix for this bug and Google ignores its presence.

What wrong with your kitkat ROM? Maybe clean flashed again. I always come back to cos11s 44s every now and then. Battery is awesome, my phone's battery is 1.5 year old and still got 5.5-6.0 sot.

Thanks again for the help and advice.
Is there a recommendation for Kitkat ROM? I'm looking for stability and battery life that surpass stock. Extra features are a bonus, but stock works well enough. It might be easier to just reset the ROM of there's no real major benefits from changing ROM. Thanks

I stayed on Slimkat for the longest time due to the MRA bug. I used this kitkat ROM more than any other. It is the leanest and fastest with the best battery I found. However, the SlimSaber 5.1.1 build has worked just as well for me. I usually get 7 hours screentime (sometimes more - as much as ten - sometimes less - as little as 5.) So it's comparable to Slimkat. No problems except sometimes the screen won't display while talking on the phone without a power button push, perhaps since I keep off ambient display. And it's a little bit snappier and just as stable with almost the same high level of customizations.

Calkulin's 3.7 is perfect... OEM rooted, smooth, quick, battery optimized and no issues. Run it on my 3 OPOs.
Yes, I'd upgrade.

Thanks for the suggestions

i would say yes upgrade. i want to downgrade back kitkat due to bad battery life but will miss may stuff like the new dialer and cant find a stable image to reflash back to kitkat. i used a onepluse one flash kit to reflash but dont use it as i cant find a proper image for it
