Checking battery status and life

To check on your laptop’s battery life, choose About This Mac… from the Apple menu at top left of the menu bar, click on More Info, and choose Power.

The status shows all sorts of useful things about the battery, including the Cycle Count and Condition.

By 300 full charges, your battery may be capable of only 80% of its original capacity. Time itself causes wear an tear also: after two years most batteries are not up to snuff, even if the recharge count is low.

You can use tools like Battery Health Monitor if you have further concerns.

Durable and fast, up to 1800MB/s
