    Hi Michael LSY!

    I see that your iPhone is shutting down by itself when the battery indicator still shows there is power left.  I know the importance of having your iPhone's battery perform well, and I'm happy to offer some help.

     

    You should recalibrate the iPhone's battery, as this can often address an issue like the one you're experiencing.  To do this, simply charge the iPhone to 100%, then let the battery die without recharging at all.  After doing that, charge to 100% again, then test to see if it's still shutting off prematurely.

     

    Thanks for using Apple Support Communities.


    Cheers!
