Android OS consuming too much battery juice. - Galaxy S 4 Q&A, Help & Troubleshooting

I just had it fully charged this morning and this is what I have found. Why does it behave like this and is there any possible fix for this?

Anyone else has the same problem?
I tried flashing stock rom, cm10.1rc4 and wiped phone many times.
Same result always.
I even changed batteries.

Battery meter

Hey guys, I'm having major issues with my battery meter. What happens is it sits at 95% all day and when it runs out it just dies without so much as a low battery warning. It used to work fine before I rooted and flashed another kernel onto the phone. I have since flashed the stock kernel back on and removed the bloat ware but the problem persists. This is somewhat of an inconvenience so if anyone has any suggestions I would greatly appreciate them. Thanks!

Take it to a store and describe your problem. You'll likely end up with a new battery. If it still happens, then something else is wrong.

[Q] Power Issues

My wife and i both have MT4G phones. While mine works perfectly fine, My wife's is having issues that I can figure out.
First, let's say that she 76% left on her battery, the phone will just power off. But when the phone is restarted, the battery will be at something like 8-20%. Now I thought her battery was bad so I swapped her battery for my battery to see if i needed to buy a new battery.
With her battery in my phone there were no issues with my phone and conversely, her phone with my battery and it does the same thing.
Anyone else have this issue?
she probably has a rougue app. One that's juicing the living **** out of that battery. Look through her apps and see if any of them run while device screen is off. Its probably an app thats syncing constantly.
You can check these by going to settings/about phone/ battery/battery use. There's you'll see the apps that are running and which take alot of juice out of the battery.
You can also reduce sync for anything by going to settings/account and sync. Thee you can change sync intervals or stop anything from syncing at all.

This is common with mine, it does it while charging. Its not a rouge app. Cause ive tried it and cannot find any app that is running it unless its shadowed. I dunno but it happen a few times already. I use cm7. Now it can also be related to emmc chip. Kinda curious only a few people have these issuses. Wouldnt it be more wide spread and more people have problems with it, if its an app?

I would say to try and do a factory reset.

That would happen to me if I wiped battery stats in recovery.
And on some Rome.usually full wipe and reflash solved it.
Haven't wiped battery stats in a long time,and I haven't had that issue since.

Battery Percent Wrong?

I am running Sttwl Droid 2.3.7 on my Dx. For the first couple days everything was smooth. Then i started noticing that my battery meter percentage was only going down and charging by intervals of 10. I have let the phone die, and then charge to 100 percent in hopes of recalibrating the battery. I have also cleared battery stats. Any idea of why this may be happening?

Try a different ROM to rule out battery failure.

That was supposed to say Steel Droid. And I have tried a few different ROMs and even a different battery. I have never seen anything like this.

Ouch ... bump charge it and wipe battery stats in recovery. Or maybe even do a fresh install. Sometimes that will fix it

Stop spreading that freaking lie. Wiping the battery stats doesn't do anything. Besides it is wiped every time the phone is charged to 100%. Don't believe me. Look it up, a Google engineer has posted this along time ago.

Darn.. really? Then CWM should take this out in the features

WIping battery stats is useful when installing a new ROM, so it can measure battery capacity better (extreme tl;dr version). Install BetterBatteryStats and look for unusual wakelocks and processes. Report back with what causes the issue and we will see. If you could include screenshots of BBS, that would be the best
You don't get it do you? It is wiped when you install a ROM. It is WIPED when you charge to 100%. The batterystats.bin has no effect what so ever on your wake locks, battery problems, or anything else you think it is related to. All it does is report to the settings what has been using the battery.

You know there are nicer ways to tell someone that wiping battery stats doesn't do anything . If it doesn't do anything than it shouldn't be in the options...period. I was trying to be helpful and offer a suggestion..and it couldn't hurt to try.
.. so whats your suggestion so no more "lies" get spread??
CWM is largely generic, so the Battery Wipe option is there whatever device. It is a waste of Dev. time to remove/customise for every device.
It doesn't do anything... in this case. It may on other devices.
But this is largely OT now... so back in the room.
It doesnt do anything for any device. A long time ago it was thought to do something. But a Google Engineer said otherwise pubically.

Guys just experienced something that this battery drain only happens to me only on Sammy jb roms and not on cm10 so is there any fix for it?????????

Check that android.process.media is not running and consuming 20% of CPU cycles. This process always runs when you restart the phone as it scans the phone's internal and external SD card for media files.

Seems like all the threads i read that mention this problem the user is running Omega rom 2.x.. Maybe its something the dev as added into the rom that is causing it to kill your battery..
Got. The solution just changed the kernel. To stock and everything is as good as it was

Mediaserver drain

I don´t know if somebody was able to fix this properly.
I´ve been through dozens of threads about mediaserver issues and I was never able to fiz this issue.
Tryed rescann median root, roms, kernels, and problem allways remains. Even with reflashing the rom to original 4.2.2 and without media files inside I´m getting allways this issue that ruins my battery.
Most of the time the drainage is higher then the screen use.
Wonder if somebody can help me furthermore.
Thanks in advance.
I think I'm having this issue too. I see that "Mediaserver" is using most of the battery under the screen, which seems to be draining the battery over night. I haven't tried flashing anything new though.
This started after I flashed M-Kernel
This is not a kernel issue. It happens with all ROMs . i think is more a Android issue. In my other devices with branded Android it never happens. Hope somebody can help.
