Battery health assistance is a new feature, introduced with the Android 16 update. On Pixel 9a (the newest Pixel) battery health assistance is turned on by default, and cannot be turned off.
On earlier models, it is possible to turn off battery health assistance.[*] This can allow the battery to hold a larger charge (higher mAh), while degrading faster. The rise in mAh would be visible through Android API's and third-party apps.
In this case, would the "estimated capacity" rise accordingly? Or, does the system appear to prevent "estimated capacity" from rising, even when the maximum mAh rises?
I suppose it _could_ set "estimated capacity" using the maximum mAh obtained without exceeding the voltage limit that _would_ be imposed by battery health assistance. Even if battery health assistance has been turned off.
I note the "battery health status" (not available on all models) is defined as whether "remaining battery capacity" is below 80% or not.
I have access to a Pixel 8a (99% estimated capacity) and a new Pixel 9.
[*] The help page does _not_ comment how this feature is related to the Pixel 6a "appeasement" payments and mandatory Android 16 update . The mandatory programme for Pixel 6a reduces battery capacity after 400 cycles, not 200 (if it has the "impacted" model of battery). Also, the mandatory programme does not mention further progressive reductions.
