iOS 8.4.1 problems
I installed 8.4.1 on my 5s last week, no prob, and a Facebook update the next day. Last night, it started to act buggy, freezing and crashing out of apps. I plugged it in to charge, turned it off and went to bed. This morning, it's turning itself on and off at its own whim, crashing out of apps and literally burning through battery. I'm currently doing an update through iTunes and, if that doesn't work, will do a factory reset.
This is my third iPhone, I've never had any problems like this. Is this normal? Is it related to the iOS update or is it a hardware issue? Is there anything else I can/should do to stabilize it? Not ready to buy a new one if I don't have to.
iPhone 5s, iOS 8.4.1
