While the performance of the M2 Pro in the new MacBook Pro 14-inch and 16-inch will draw the most attention, the battery life may be real highlight with Apple boasting the 16-inch model will offer the “longest battery life ever in a Mac.”
It’s a
Current MacBooks with the longest battery life
Just like every laptop that comes in for review, we put MacBooks through our rigorous battery life test that involves continuously surfing the web on Wi-Fi with the display set at 150 nits of brightness. While your mileage will vary depending on your usage, this gives us an accurate look at which laptops will offer you the best battery life.
Here’s a rundown of our battery life test results for the current MacBook lineup.
| Battery life (hh:mm) | |
| Apple MacBook Pro 13-inch M2 | 18:20 |
| Apple MacBook Pro 13-inch M1 | 16:32 |
| Apple MacBook Pro 16-inch M1 Max | 15:32 |
| Apple MacBook Air M1 | 14:41 |
| Apple MacBook Pro 14-inch M1 Pro | 14:09 |
| Apple MacBook Air M2 | 14:07 |
How will the MacBook Pros with M2 Pro and M2 Max stack up?
Apple claims that both of the new MacBook Pro models will offer an hour of additional battery life over their predecessors. It’s important to note that Apple’s test is Apple TV app movie playback, which is less taxing than our test so yields longer runtimes.
For the 14-inch MacBook Pro with M2 Pro Apple indicates it will last 18 hours (up from 17 hours) and the 16-inch MacBook Pro with M2 Pro will go for 22 hours (up from 21 hours).
We’ll have the official answer when we get these laptops in our lab, but for now we wanted to take a look at some of Apple’s claims versus the final results to see how close we can get to the real numbers.
The M2 and M1-powered 13-inch MacBook Pro owns the two top spots currently. Interestingly Apple claimed 20 hours of video playback for both, but the M2 model scored a decisive victory with almost 2 full hours of additional battery life at 18 hours and 20 minutes.
However, things are a little different when we turn to the only other laptops that we have M1 and M2 results for at the moment, the MacBook Air. Apple reported 18 hours of battery life for the Air M1 and an astounding 20 hours for the Air M2. Both came up well short of these marks with the Air M1 dying at 14 hours and 41 minutes, while the Air M2 called it quits at 14 hours and 7 minutes. The latter is almost 6 hours or one-third shorter than Apple’s reported battery life.
The discouraging piece of the puzzle here is that the Air M2 mirrors the design of the 14-inch and 16-inch MacBook Pro. There’s nothing intuitively about the design that suggests it should take a thermal hit versus the old MacBook Pro design, but if the new models follow that path we could see them backslide a bit. To be clear, they have room to spare and still deliver some of the best battery life in their class, they just might not live up to “longest lasting battery ever in a Mac.”
The optimistic side of things would be looking at the MacBook Pro M2, which suggests we could see an even greater bump in battery life than Apple is projecting and the 16-inch MacBook Pro M2 Pro offers longer battery life than any mainstream laptop we’ve ever tested.
You won’t have to wait too long to find out.
