Battery drain problems

My gpad the wifi version running Android 4.4.2 got problem in retaining battery. It drains about 4 to 5 percents of the battery when the pad is in idle for about 10 hours. The pad is new so i don't think is the app i downloaded that is causing the problems. It must be something have to do with the manufacturer. Are you folks having the same problems? May be i need to flush it and reload the android to get away the apps installed by the manufacturer. Any ideas? Thanks.

Sound better than average to me (I've had quite a few tablets&phones ... but only have this GTab for 2 days).

that is actually quite good,mine use to lose 10+%.got it to only lose about 2-3% by using clean master.just kill everything when i go sleep.give it a go.

Thanks will give it a try. There are just too much possibilities here. Need an expert to figure it out.

Download App Ops Starter from playstore. Look for apps that keep your tablet from going to sleep and turn off that setting. Also you can turn off their ability to spy on you.

[5.1.3] AndroidOS constantly downloading data in the background causing battery drain

My OnePlus 5T running the latest Oxygen OS 5.1.3 started having a battery drain issue since yesterday. Battery life went from almost 2 days to around 4-5 hours suddenly.
I checked around the phone and found out that "Android OS" is keeping the phone awake at all times since it continuously downloading some data in the background. It managed to download over a 100 GB of data in 1 day.
I've tried factory resetting the phone but the the problem came back in a few hours and it's managed to download around 13 GB again in the last 3 hours. I'm not aware of a way to figure out what exactly is being downloaded. Is there a way I can trace exactly what's happening in the background so that I can look for a fix?

Hmm, very interesting...
I'd suggest installing ES explorer. The app tracks the storage space and will give you a report on big files as well as the new ones.

it must be an app reported as androidOS
check your installed apps 3rd party and make a screenshot for use may be we can choose it out

If you click on Android OS in data usage, it will show what things goes under Android OS. Maybe one of those has the answer.

[Q] New Z2 play from China has huge battery drain.

I bought a "bargain" Z2 play from a China seller, and find it drains battery in about 7 hours.
drain occurs out-of-box with no updates. Flight mode doers not help.
Box was opened, I assume to flash international firmware. Phone is not "Play protect certified", so no google pay. Netflix works, but had to be side-loaded.

Utilities report around 600mA with screen on, over 400mA off & idle.
So charged, screen off and idle, phone is warm and runs flat in around 7 hours.
settings->battery does not show any apps with high usage.
XT1710-08 PVT1 Android 8.0.0 with 1st June'18 patch.
Anything to try before attempting RMA to China?
Should I try another firmware, or would that void warranty - if a Coolicool china warranty is honored.

A few days later, after numerous tests and factory resets, the problem suddenly went away.
About 1.5hrs into a 5 hr test in standby, the logs show the drain suddenly stopped.

Problem has not been seen since, even after firmware reset.
Any ideas? I hope it is permanent.

Looks like cosmetic changes only. Not bothering with the rooting song & dance because of that. Call me again when we get Pie (guess I'll already have a new phone before that happens).

You are an insult to my country

I had several issues with that update after the installation (themes, authorizations, grid layout). I was able to solve most of them but now my biggest issue is that the battery drains way faster than before. With the 10.0.2.0 version I had around 6 or 7 hours of SOT. Now i'm only at 5 at most.

Android 10 Update Bug Screen Flickering

Have a look at this ...
scary :laugh:
https://youtu.be/2K6OfvVCSus

My 835 did something similar the first "real" restart after Android 10 got installed, went on for ~20-25 seconds I would say, then I pressed the screen on/off button twice, all came back and I could unlock the SIM and continue ... hasn't happened since ... but was indeed scary
Marcher

I had the same problem too. Another reboot cleared it.

Didn't have this issue. But I noticed new battery settings and turned on the "protect battery" feature and now seemingly my sot has improved by a crazy amount I'm not sure if it's a bug.
The feature basically just makes it so your battery won't charge higher than 85%, and then when it says 100% after restart, it's the same as just 85% before. I can't post image for some reason, but I'm currently at 53 minutes of SoT and I'm still on 94%..

Got the same issue randomly (twice since Update), thought itˋs Hardware(GPU) Problem. Iˋm going to do a Clean Android10 Install if i have the time to.
