MacBook Air M5 battery health at 96% and draining quickly

Hello everyone,

I bought my MacBook Air M5 in July 2026, and I’m concerned about its battery health and battery life.

As of October 2026, the battery health has already dropped to 96%, and I’ve also noticed that the battery drains really fast, even during normal use without running particularly demanding applications.

Here are my MacBook’s details:

  • Model: MacBook Air M5
  • Purchase date: July 2026
  • Battery health / maximum capacity: 96%
  • Cycle count: 45
  • Battery condition: Normal
  • Operating system: macOS Tahoe 26.6.2


My charging habits:

I generally try to preserve the battery by keeping the charge between 20% and 80%. I rarely charge it to 100%, and I usually avoid letting the battery drop below 20%.

The MacBook also rarely gets hot, so I don’t think excessive heat is a regular issue.

For that, read If your Mac battery runs out of charge quickly - Apple Support, and in particular the following passage:


"Even an app you aren’t using may be working in the background and consuming energy."


Activity Monitor will readily identify those apps or processes: View CPU activity in Activity Monitor on Mac - Apple Support. High CPU usage = high power consumption = rapid charge depletion.


96% is nothing to be concerned about though.

Hi,

I think your battery is normal, 96% is fine and nothing wrong and your charging habits are fine.

Hey John, thank you for your reply!

I'm definitely following the recommendations in the article.


Regarding Activity Monitor, Brave Browser is currently the only application I'm using, and its CPU usage is around 12%.
