There was very little difference in performance or battery BUT in H7:
- The unlock button behaved properly for the first time. Unlock was faster and it wouldnt do that wierd thing where you need to press it for just the right amount of time.
- I consistantly had 40mb free on boot and ~30mb after normal use. Now I have ~30mb on boot, and ~20mb after normal use
- The phone didnt randomely power off
That's about all, but these little things are really anoyying for what seems very little or no benefits in I5
