Pixel Watch may soon support Adaptive Charging for better battery health

Through a recent app update, evidence has been spotted that Google may bring Adaptive Charging from Android to its smartwatch, the Pixel Watch.

Spotted by the folks over at Android Authority, a code snippet from the “Pixel Watch Management Service” app hints at support for Adaptive Charging. The code names the “Adaptive Charging Service” by name, but offers no further context into how the feature might be implemented.

On Pixel phones, Adaptive Charging works by learning a user’s charging routine and tailoring the charging speeds to lessen strain on the battery. In turn, the battery’s lifespan is improved over time, all without any intervention by the end user.

Google explains:

To help extend battery lifespan, your phone learns your charging routine and waits until your need it to fully charge.

This would certainly work differently on a smartwatch, but could still prove useful. Charging habits for smartwatch users will vary drastically from person to person, as some may use their smartwatch overnight for sleep tracking, while others may just leave their smartwatch on a charger during that time. In the latter scenario, Adaptive Charging on a Pixel Watch could learn to charge slowly overnight instead of going at full speed which, over time, would certainly help lessen any strain on the battery. Google also added a battery limit to Pixel phones last year, which could also prove helpful on a Pixel Watch if it were implemented. There’s no sign of that just yet, though.
