My blackberry Z10 randombly turns off

I read online when blackberry turn off is because the battery is low but I have the same problem when my batter is at 70% or more. I've been having this issue for well over a year. I don't have enough money to buy another type of phone that's why I still have it otherwise I would have changed it for an iphone which works awesome. The blackberry by the way has awesome reminder, calendar, easy to email, and the battery does not drain as fast. I really wish I can find a solution for this problem.

Try upgrading your OS or check on here to find a thread about re calibrating the batter.

You might need to make a shim to put next to your battery. I had the same problem and that worked for me. The battery gets loose in there after a while.
