Macbook air M1 battery capacity drops 98% in 34 cycles

Hi Team,


My M1 Macbook air battery capacity drops to 98% in just 34 cycles. Can I know the reason why it is dropped so fast? is that normal? I have only used 5% out of 1000 cycles and it doesn't look normal to me.


  • I have turned on my optimized battery charging
  • Brightness at 40%
  • using 70% silicon apps


I would be grateful if someone responds to me.


Best,

Mani

MacBook Air 13″, macOS 11.4

As a user, I wouldn't worry about it now.


macOS manage battery health now.


How battery health management helps

The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages.

 The feature does this by monitoring your battery's temperature history and its charging patterns.

Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode.

 This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, 

and slowing its chemical aging. Battery health management also uses the measurements to calculate when your battery needs service.
