Typical Charging Times for MacBook Pro Models

The following table summarizes approximate charging times for various MacBook Pro models using their standard chargers under ideal conditions (device powered off or asleep, ambient temperature around 20-25°C):

MacBook Pro Model Charger Wattage Battery Capacity (Wh) Approximate Full Charge Time
13-inch (M1, M2) 61W 58.2 Wh 1.5 to 2 hours
14-inch (2021, M1 Pro/Max) 67W or 96W 70 Wh 1.5 to 2.5 hours
16-inch (2021, M1 Pro/Max) 140W 100 Wh 1.5 to 2.5 hours
16-inch (Intel, 2019) 96W 100 Wh 2 to 3 hours

Charging times may be longer if the MacBook Pro is in use or if charging occurs in a warmer environment.

How Charging Speed Changes During the Cycle

Charging a lithium-ion battery like the one in a MacBook Pro follows a two-stage process:

  • Constant Current Phase: The battery charges rapidly with a relatively high current until it reaches about 80% capacity.
  • Constant Voltage Phase: The charging current gradually decreases to avoid overcharging, slowing the rate as the battery approaches 100%.

This process is designed to maximize battery longevity and safety. Consequently, the initial portion of charging is faster, with the final 20% taking roughly as long as the first 80%.
