Battery draining too fast

[darky123]

I have noticed that the battery is being depleted in an alarming rate (less than 3 hours of screen time), but the battery settings pagr doesn't notffiy of any unmoral behavior by any app, and what's more - the percentage breakdown of battery drainage doesn't add up to the depleted percent of the battery.
I would like to know what app to use in order to get a real account as to what app is using all the battery.

GSam Battery Monitor should give you plenty of information in that regard.
