[AC Question]

Hi guys. I bought an S7 some week and a half ago and ever since I bought it battery seemed to suck. I believe it might be faulty. Before i give the phone back to the retailer and lose it for a week, just to possibly be told that its some apps running in th3 background thqt run battery dry, id like to benchmark it (or something like that).

Are there any tools or ways if testing a battery to see if its faulty?

Right now my phone will lose some 15-20% after being charged in less than an hour, without even being used. Writing this post on the phone ate up a few percent.
It doesnt last a whole day and i wouldnt say i used the phone a whole lot. My screen was on for 1h and 8 minutes. I listened to some music, sent a few messages on messanger & had few minutes of phonecall. Battery is at 13% after being unplugged some 10 hours ago.
