Google Slows Pixel Watch Charging to Improve Battery Health

Original Pixel Watch now takes 15 mins longer to fully charge than before
Slower charging can help ensure good long-term battery health
Previously, Pixel Watch could go from 0% to 50% in 30 mins, 80% in 55 mins, 100% in 80 mins
Now takes 45 mins to get to 50%, 75 mins to 80%, 110 mins to 100%
While fast charging is convenient, it's not best for your device
Google likely slowed charging to protect the Watch
There were reports of Pixel Watch backplate randomly falling off and overheating during charging
Wireless charging generates a lot of heat which can damage device and battery
Slower charging prevents overheating which caused backplate issues
Firmware update only applies to original Pixel Watch, Pixel Watch 2 still charges fast
Pixel Watch 2 uses pin charging which doesn't get as hot
