Yesterday my IPhone SE randomly powered off while it was at full battery. It turned back on shortly after and I thought it to be a one time thing but ever since than it's been powering off like that every five or so minutes. I've been meaning to upgrade my phone anyway -- the entire backside is shattered. The issue is I haven't backed up the data in a considerably long amount of time. Every time I try to initiate a backup my phone just powers off after a few minutes and I have to start all over again once it turns back on. I'd like to know if there is any way I could resolve this issue without losing all of my data. I'm going to get it checked out tomorrow but I worry that there is nothing they can do. If possible I'd like to find a way to keep my phone on long enough to do a backup so I can transfer the data to my new phone.
