Phone restarts (and stays in loop) at 70% battery

[Thom12]

I can only use my phone for about 1,5h then when it hits 60-70% is goes into a restarting loop and becomes useless.
If I have the phone plugged in, I can work with it but that kinda beats the idea of a mobile ;-)

Should I get a new battery or do I have some kind of bug on my phone?
Any help is welcome

That's pretty strange.
Before getting a replacement battery you could try booting into Recovery mode and clearing the system cache. If that doesn't work I'd do a Factory Reset.

What's your 'Available space' like (Settings -> Storage)?
