Should I charge my MacBook Air M3 to 100% or 80%?

To get the most from your battery:

• Let the OS and charging circuits manage the charging.

• Plug in when using the computer near available power.

• Use on battery when ac is unavailable.

• Don’t subject the computer and battery to extreme temperatures.

• Try not to allow the battery to discharge deeply regularly before plugging in. Yes, it may happen from time to time, just don't make it a habit.

• Don't obsess over battery life and/or health.  

Here is Apple's guidance on the subject.

In the long run, it probably doesn't matter very much. The charging algorithms built into the Mac will take care of it better than you could.
