No, it isn't. Neil has answered it correctly, the current charge level is separate from the battery health.


What are you saying?


100% charge for a battery health of 80% is a lower charge than 100% with a battery health of 95%. How much energy there is with the percentage charge level is relative to the battery health. It's always been like that.


Some tools like coconutBattery will display current charge level in mAh. They list battery health the percentage of the full charge capacity relative to the design capacity. Current charge percentage level is relative to the full charge level.
