Battery Cycle Count on MacBook Air

Leave the computer plugged in whenever convenient to do so. Leaving the computer plugged in will not damage the computer of the battery, and doing so will reduce the rate of accumulation of battery cycles.

starting from 100% what percentage should i plug in my charger?

Leave it plugged in whenever convenient to do so. Plug it in at 100% or any other percentage and just leave it plugged in until you need to move it to another location then plug it in at the new location. Use it on battery when no power plug is available.

okay thank u so much! last question, from 100% to 70%, is that considered as a 1 cycle count? because i noticed that i fully charged my macbook and then when it reaches 77%, then when i checked the cycle count it increases huhu

Here is an explanation of how cycle counts are calculated:

Ignore the Battery Cycle Count....it is meaningless unless it is nearing 1,000 cycles.

In fact, just ignore the Maximum Capacity value as well since people don't understand how these Apple Lithium batteries behave since the Maximum Capacity value was only recently introduced a few years ago.

Just use the laptop until the battery is no longer performing to your expectations. Then and only then, check the Battery Condition to see if the condition is shown as "Service Recommended". If so, then it means it is time to have the battery replaced. Otherwise you can even ignore the "Service Recommended" condition because why would you want to replace a battery that is not giving you any problems?
