Picking up on power consumption, I note a clear diminution especially when the phone is inactive (but not turned off). At night if I forget to switch on Airplane mode, consumption seems hardly (~ 2-3%) more than with it on ~ 1%). I could probably now go for four days on a full charge, but I usually keep to the 20% - 80% recommended range or narrower, so I just top up every other day or so. I seem to remember reading somewhere that this improvement was expected, but that doesn’t make it any less welcome!
Obviously power usage with the screen on is going to remain unchanged.
Good job
