lately, her phone just turns off, in her pocket, while she is texting, whatever. Battery will be good. When she turns it on, battery is only at 5%. She has many different batteries, she claims they all do this, not just one. I have been reading on the internet about other people having this problem, usually good at wifi or getting a new battery, but thats not the case with her. Also, other people says the phone charges quickly after this happens, but not her. So whats wrong.
