Weird battery drain and overheating?

[Noah Armstrong]

Hello. I updated to lollipop, and when I am heavily using my phone, it stays cool and the battery is acceptable. When I don't use it, the battery drains Alot (about 55% in 6 hours) and the phone gets super hot. I have downloaded gsam battery, and it doesn't show anything unusual. My battery settings say that the Android system is using 19% currently, but jumps to 65ish% when the phone is on for a long time. Help please!

The same for me! It will drain at about 12 percent an hour on standby on 4 bars of LTE.

Welcome to Android Central! Is Cell Standby a high percentage, and are you on wi-fi during this time? S6 owners are seeing that problem, but I don't know if it's also a problem on the S5 on Lollipop.

Another thing to try is to unmount the SD card (in Settings>Storage), removing it, and rebooting. A corrupt file on the SD can cause overheating and battery drain, because the Media Scanner gets stuck on that file and works overtime.

Cell standby is about 1% compared to the android system at 19%. I have kept WiFi off as much as possible. And I have turned off location.

Have you already tried wiping the cache partition? That can help with various issues after a system update: http://support.t-mobile.com/docs/DOC-10404

I don't know if it's also a problem on the S5 on Lollipop.

My guess is its a software configuration issue. Rogue app or wonky software update that a cache clear or factory reset may fix. Many of us have outstanding battery life with the S5.

I have cleared my cache. So it is not my android system drawing power? When on for about 5 hours, it says my stay awake is 20-40 minutes.

It appears to be a Lollipop issue. Some people have reported an update last night (with no change in any of the phone information) that seems to have cured the problem.

Anything look out of the ordinary? BTW, I'm on AT&T.

The mobile signal doesn't look that great around the time the battery is draining quickly--I still wonder if poor signal is one of the main problems.

 

[Noah Armstrong]

Where there's no signal, it was off. It didn't move much when it was on, so I have no idea why it would be bad. I have 4 bars at my house.

But if mobile data were off, then there would be a gap. Where the steepest decline is, there's actually active mobile signal in the graph.

I noticed a battery issue also and recently got a update to samsung push services. Could that be the issue?

I think it may be my heart rate monitor. When the screen is on, and it's on a flat surface, it's continuously on.
