Weird battery usage

[alexwyc92]

Hello, there. Recently, after opening Maps, my oneplus one's battery usage becomes very weird. The Maps which I have opened for a while suddenly spikes on top of the usage list and my other app usage disappears. Why is such thing happening? My oneplus one is on Android 6.0.1. Thanks for any help or insight.

There seems to be an error in the battery usage stats. That says that maps used up all of the battery that has been drained so far. Also, it can't use up 9 quintillion mAh, so your stats are off, but Maps doesn't use that much battery.
