iOS 10.3.3-12.0
hey!
I'm running my iPhone 7 on 10.3.3 due to last year version (iOS 11).
After only a week of use, after updating to iOS 11.
My iPhone became unusable.
Battery drained like nothing, from 8 hours of intense use to 3-4 and tons of bugs.
Luckily I were able to downgrade back to iOS 10 and I'm still there.
So the question is, Should I update to iOS12?
Am I going to get performance improvements or trashy battery life?
