The whole 'plus' point of owning an iPhone is the ease of use, and I pay for iCloud storage space. Why would I want to lose my back-up? I went through that carry on with my iPhone 5 and spent a whole weekend setting it up from scratch only to find that my battery drain issue was still present. I'm reluctant to do a set-up as new when there is only a slim possibility that it will cure my problems.
Incidentally, which weird issues does my iPhone suffer from? It doesn't have the low volume problem, or screen issues etc. It lags and the screen is at times unresponsive, but these are well documented 6+ problems. The health app doesn't really bother me but I was wondering why it seemed to reset itself every 24 hours...
**EDIT** The health app is working, doh. I didn't realise that it didn't tot-up flights climbed etc, it instead records them individually. I have lots and lots of entries for the same day and they *are* showing on the graph. I'm sure they weren't there yesterday!
