For anyone having issues after the update, please give it a few days to settle (as with any major OS update), and the battery life should improve.
If not, I suggest backing up and doing a factory reset. That will most certainly fix any issues.
Yeah same with mine -- I've tried everything now. Even factory reset and started from scratch to see whether it has any positive impact but none so far.
I was also in one of the 1st waves to receive the update end of May so, I've had plenty of time for the device to get "used to the new OS" but the battery has not improved whatsoever.
In fact I feel it's draining even faster as the days go on....
Anyone having any luck with their battery? I did factory reset ( didn't restore from backup for my apps either ), still not great for battery life at all 😞
