She’s recently upgraded from 10.x to latest version. She’s noticed an actual decrease in performance to the point where she’s nearly punching the phone. It just locks up for no reason.
I’d like to blame this on the battery or age of the phone but I can’t. It is an iPhone 6 but it is only half a year old.
I believe that this phone should be able to handle the latest release just fine.
She’s now looking at upgrading the phone.
