Why does my iPhone randomly shut off
Here's the story:
I'm on t-mobile's network and i wanted an iphone, so i went to ebay and i found one that cost about 168 bucks a few weeks ago, the first day i got the phone it randomly shut off and it's been doing it up until now the phone will be at between 90, 80 or even 68% and shut off randomly, and it won't turn on unless i plug it up to a outlet charger, it's soooo Frustrating. do I need to get a new phone, or do i need to get a new battery? I've been searching this for weeks and I still haven't gotten any help. I need a solution.
Is this a good question?
