Google Pixel Adaptive Charging requires alarms to be set during a specific window Shane McGlaun - Dec 31, 2020, 7:06am CST In December, a new update for Google Pixel smartphones added in some new features. One of the most interesting features was Adaptive Charging, designed to allow the phone to charge slowly overnight to help preserve its battery health. The idea is to help preserve battery health over time by dynamically controlling how quickly a Pixel device charges. The goal is to help the battery retain all of its original capacity for as long as possible. Adaptive Charging is available on the Pixel 4 and 4 XL, Pixel 4a 5G, and Pixel 5. The setting can be manually enabled and disabled inside settings – battery – adaptive battery – adaptive charging. When active, there is a notification at the bottom of the ambient/always-on display.
