Apple MacBook Pro 14" (M4, 2024) battery capacity & backup time

Apple's spec page lists 72.4 Wh for the Apple MacBook Pro 14" (M4, 2024) (Apple lists 72.4 Wh). The capacity of yours is printed on the battery label and shown as "design capacity" in a Windows battery report.

Estimated for a new 72.4 Wh pack at about 60% brightness: 11 h 30 min of browsing or office work, 7 h 40 min of video calls and 2 h of gaming. These are estimates from typical power draw, not measurements.

On a used battery at 80% health with the 72.4 Wh pack, office work runs for about 9 h 10 min, so a 2-hour outage is covered for the laptop itself. Your Wi-Fi router still needs a mini UPS; the load-shedding calculator works out both.

Replace it when the full-charge capacity falls to about 60-70% of the design capacity (around 47 Wh on a 72.4 Wh pack), when the laptop shuts down at 20-40%, or straight away if the battery swells and lifts the keyboard or bottom cover. Run powercfg /batteryreport in Windows to see both numbers.
