I had the top case replaced for keyboard issues back in March (spacebar jammed, keys not registering or double-registering). The new battery has 24 cycles on it but only has a capacity of 4652 mAh -- or 97.1% of the rated capacity. The last time I checked the battery capacity it was at slightly over 98% with 20 cycles. Does the rate of battery degradation slow down over time? If not, I can't fathom how this battery will make it to 1000 cycles. Thanks for you help.
