We won’t make batteries final ceaselessly, however we will help them last more. Charging optimization is one Android 15 function value exploring, because it’s designed to just do that. It provides a brand new choice to restrict battery charging to 80%, which helps decelerate battery degradation. This sacrifices day-to-day battery life to protect long-term battery well being. Is that this a function value activating, or do you have to keep on with Adaptive Charging, which we have had for some time? Let’s dive in.
This information relies on Charging optimization because it seems within the Android 15 beta working on a Google Pixel 8.

What is the level of limiting the battery cost stage?
It is all about preserving battery well being
Battery life expresses how lengthy a telephone lasts between costs. Even the telephones with the very best battery life usually final a day or two earlier than they want recharging. This isn’t to be confused with battery well being, which signifies how a lot capability a battery has misplaced over time.
