iPhone 6 Plus freezing and battery draining
My iPhone 6 Plus keeps freezing and is completely unresponsive, then when it finally unfreezes the battery is depleted - even if it was 100% prior to the freeze. When it freezes, nothing works to unfreeze - I am unable to kill apps or shut off the phone, I just have to wait until the phone decides to cooperat. What is the issue?
iPhone 6 Plus, iOS 9.3.1
