Andrew:
When I upgraded my old Series 4 to watchOS 7, I noted a sharp drop in battery life, seldom making it through a full 20 hour day, and often going into the red after 14 – 16 hours of operation.
It’s great that there is now a bug fix, but just in case anyone’s battery life does not return to pre-OS 7 performance, I found, as has been previously suggested with battery life issues, that un-pairing then re-pairing the watch with my iPhone restored the watch to its pre-OS 7 performance.
