Apple Watch Battery draining fairly quickly; Battery Health stuck at 80%
- For context, I have an Apple Watch Series 7 SS+Cellular. I bought it at launch, and it's been my main watch since then; I even use it as a sleep tracker.
- If I use it while sleeping, I charge it back to 100% after waking up.
- For the past few months, I've noticed less battery life, and the Battery Health percentage degraded quickly over the weeks. IIRC, it was at 85% the first time I saw it, and maybe a month or so after, it was at 81%
- I've contacted Apple Support and followed all their recommendations, such as a factory restore. However, the issue persisted, and they always mentioned service was not needed due to the Battery Health status.
- Now, the Apple Watch reached 80% and has been stuck there for about a month, maybe a bit more, which I find very strange considering the Apple Watch battery health degradation history/trend.
- I know it's a reasonably old Apple Watch, ~two years of use, and battery degradation is expected. However, I find it super suspicious that it would stop decreasing the percentage at 80% (considering that service is due under 80%).
- The Apple Watch is under an AppleCare+ subscription, so I don't see why requesting service would be so tedious and why the OS would stop the Battery Health at 80%.
