Your battery health is exactly where you should expect it to be. On average, you should see a 1% drop for about every 50 cycles, so expect another one coming up shortly. The battery is expected to last 1000 charge cycles before the battery needs replacing when the battery health drops below 80%.


The battery drop is not linear, so some months may not drop at all and other months will drop more. If you use a Charge Limit, be aware that the calibration only occurs when the battery is able to charge to 100%, which it will do automatically on occasion even when using the Charge Limit, as long as it has not been removed from the charger before the device was able to continue to fully charge.
