iphone 6 is getting warm and battery drain very fast
I am a owner of an iPhone 6 ios 9.2.1 and my problems are : While using different apps like periscope , antutu , Skype video call using "LTE" or Facebook messenger my phone is getting very warm and battery drain so fast..I've tried a lot of things like factory reset and rebooting, stopped push notifications, no brightness , stop background app refresh but nothing happen. What do you suggest? Do you think that problem it's because of the ios 9.2.1?? Does anyone have the same problems? Thanks for all!! P.S Sorry for my bad English. PLEASE HELP !!
