Why your Pixel sometimes ignores the 80% charging limit

Google has introduced a new battery health feature to Pixel phones that limits charging to 80% to help maintain long-term battery performance. This addition follows similar features from other Android manufacturers and Apple.

However, you might notice that your Pixel sometimes charges to 100% even when the 80% limit is set. This isn’t a bug—Google does this for an important reason.

When the Settings Services app (version 1.1.0.697513890) was updated, users discovered a new explanation in the Charging optimization menu. The occasional full charge is done to “recalibrate” the phone’s battery. This recalibration ensures the phone accurately estimates battery life and avoids errors, like shutting down prematurely because of incorrect battery predictions.

This approach isn’t unique to Google. Apple’s iPhones also override charging limits occasionally to keep the battery health data accurate.

The charging limit feature is a welcome addition for Pixel users, as it helps reduce battery wear over time. Hopefully, Google will also consider adding other advanced battery features, like bypass charging, in the future.

This small adjustment reflects how even tech companies balance performance with user convenience for better device longevity.
