My LG G2 (F320) turns off !

Hello guys ..
I'm facing an annoying problem since I bought my LG G2
when the battery is 50% or less
my phone keeps turning off I have tried to change the battery but nothing changed ..
I'm using the Korean version (F320) .. any suggestions ?
Thank you

Welcome to Android Central! I wonder if it could be a faulty power switch. You may have to bring it to a repair shop for further diagnosis.
