Apple Watch 6 battery drain
My Apple Watch 6 has very recently - within the last month - been experiencing rapid battery drain. Prior to this past month, my battery would last a day and a half - depending upon use - before a charge. Now, some days the battery does not last 24 hours. After reading numerous discussions, I found that if I unpaired and re-paired my watch from my phone, it would function properly. However, this solution lasted only 2 weeks. I unpaired and re-paired again and it went back to functioning properly. I am now at another 2 weeks and my battery has not lasted 24 hours.
My use has not changed in these two weeks - I use the Workout app daily but do not use my watch for music, calls, or any other high-battery-drain feature.
Is this a software issue or a hardware issue or neither? I don't want to upgrade my watch if it's a software issue.
