Interesting. I have a s6 since Nov. 2020. Optimized battery charging is disabled and I charge it overnight every night. This year in February I replaced the battery because it dropped to 82%. Now in November it’s already at 90%. The replacement was done by a licensed shop and my usage is the same.

My Apple Watch Series 3 Cellular will be will be 5 yrs old this November. Battery capacity is at 100%. I use it as a spare since purchasing the Ultra OG. Do I believe the 100% reading? Not really.

My series 5 I got in November 2019 is at 72% max capacity unfortunately

My series 6 bought brand new is now at 82% battery health.

What is the WatchOS version on this?

my s7 is at like 86 but I use the Sauna for 10 minutes everyday and I think thats probably the reason.

My S6 has lower battery capacity than my S3. I think the newer version has poorer battery due to the always on display.

Interesting indeed!

Incredible!

Bought my S7 on January 2023 and it’s at 99% now so yours looks great

Series 4 45mm stainless steel at 63% 😢

Series 4 with 83%, bought it on eBay earlier this year for $80 though

Mine old one was 98 haha
