Installed on my Air within a few hours of release. Whilst very smooth and battery for the most part was excellent, I was seeing periods where the phone would get very hot and battery would drain excessively with normal non-heavy use. Never had heat issues before, and the odd reboot didn’t seem to resolve it. Yesterday, I did a reboot, then force closed all apps, rebooted again twice in a row and everything seems to be normal again. No heat issues or battery drain. No idea what was causing it but sharing in case anyone else encounters this randomness.
