Can't find cause of excess battery drain

[Android Central Question]

I have a C5 pro. I normally get decent battery life for a couple of days after a restart - 50% in 18-20 hours, .3% to .5% idle overnight (usually 6-9 hours) according to gsam.

After a couple of days using the same apps and programs the battery drain increases to 1.4% when Idle which is a significant increase. 50% drain in 12 hours rather than 18-20%. The Android OS goes from 7-10% to 25-30% usage.

Then I restart again and it's all fine. I'd like to be able to narrow down the cause. I look at Gsam and there doesn't seem to be any app that sticks out other than the Android OS.

Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
