Hey guys! Does anyone have an iPhone 5 or 5c (shouldn't make a difference, right?) and already upgraded it to iOS 10? My sister and mother are both on an iPhone 5c and I'm not sure yet if I should upgrade them to the most recent iOS release. In the past, I often heard of more or less heavy problems in terms of performance with iOS updates on the "lowest end" model for the respective release (iOS 9 on iPhone 4S, iOS 8 on iPhone 4 etc.). Since the iPhone 5 (and 5c) are the oldest generation to receive this update, I'm a bit concerned that they'll experience similar performance issues and I'd rather let them run a stable iOS 9 than a buggy iOS 10 - especially since there are not many features that my mum and sister actually "need". Has any of you tested this yet? Are there any performace issues or does iOS 10 run just as fine as iOS 9? Feedback would be hugely appreciated. THANKS!
