Unknown battery usage

rzldx — Mon, 07 Sep 2015 12:40:06 GMT

Today I found an unknown battery drain right after I charged my phone to 100%. I didn't use it at all but the battery decreased 5%. Here's some screenshot

Is there anything wrong with my phone? How to prevent this from happening again? For additional information, I've been using my phone for two months.

As I see it,it was the network signal that caused this.

How about this? from around 00:00 to 04:00, I was sleeping, the battery kept decreasing even though I put my phone on airplane mode and I closed all opened apps before I went to sleep. I'm sure no apps were running but the phone was awake. This is the first time it happened, so please help...

You have apps running in the background. Can you check if the same issue occurs in safe mode?

I'll try it if it happens again. Thanks for the suggestion!

As you can see in the second photo, the phone is constantly awake even when you're not using it. You have a rogue process.

If you can't find it, I'd recommend resetting your phone to erase it.

Good luck.
