iPhone 6s battery drain, overheating and poor standby time
I recently bought an iPhone 6s, coming from a 6. I've noticed that the battery life is pretty poor, and I only get around 2-2.5 hours of usage before it dies. The standby time is also no way near what I expect from an Apple product, it drops 20% overnight. Furthermore, it overheats on the back (just above the Apple logo when I use it for more than 10-15 minutes. Is anyone else experiencing this? Is it worth taking it to Genius Bar to get it checked out? Thanks!
iPhone 6s, iOS 9.0.2
