Yeah she's running much snappier little buddy. Very happy with the performance.
OP, I wouldn't hesitate to update!
After you jailbreak your iPhone 5s, are you going to give it to your son? I bet he would really like having an iPhone. I know I would. Let Me know how the jailbreak goes.
I know what I'm talking about. iPhone 5s with iOS 10 has some lags in Notification Center, widget center and so on. It's slower opening app and in some animations. iOS 9 is better, iOS 8 way better. You can't think a new iOS is faster in older device. Is usable but not fast!!Some tend to think their iPhone 5s can't run efficiently on iOS 10 and stay 9.3.5, who are afraid to update it! Clearly they don't know what they're talking about.
