Huawei mate 2 won't work

[Chipstak]

So I have a huawei ascend mate 2 phone. I was on at&t network . I'm having trouble getting the phone to stay on... when I turn it on sometimes it just shows the huawei symbol and that keeps flashing on the screen.. or it will go to my home screen but I'm only able to keep the phone on for a minute or so... can't figure why....
Anybody have this issue ?

well your phone is pretty old. it is well over 6 years old. it could be many things, i'd start with trying to get a new battery.
