Understanding iPhone Battery Maximum Capacity: Features, Issues, and User Feedback

The Maximum Capacity feature allows users to monitor the health and degradation level of their iPhone battery, introduced by Apple after the controversy about slowing down performance due to battery degradation.

Apple introduced the Maximum Capacity feature in response to accusations and user complaints about intentionally slowing down iPhones with degraded batteries to preserve battery life and stability.

The Maximum Capacity feature indicates the health of the battery over time. For example, if it shows 95%, it means the actual stored charge is 95% of the original capacity when fully charged.

Peak Performance Capability is a feature that allows users to choose whether they want their iPhone to perform at its maximum capacity or to reduce performance for longer battery life if the battery is significantly degraded.

Yes, since iOS 11.3 beta 2, users can monitor battery health and decide their iPhone's performance level, even if the battery is degraded by more than 20%.

There have been user reports and discussions on tech forums about the inaccuracy of the Maximum Capacity feature, with some users experiencing fluctuating capacity readings.

Apple acknowledges that regular usage and charging cycles impact battery health. If the battery maintains over 80% capacity after 500 charge cycles, it is considered normal.

If users notice significant battery degradation, they can contact Apple Support for further assistance and potential battery replacement options.
