In summary:
- Macworld compares MacBook battery capacities across Air, Pro, and Neo models, revealing that 16-inch MacBook Pro models offer the highest capacities up to 100Wh.
- M-series chips significantly improve battery efficiency, with newer MacBook Pro models achieving up to 24 hours video playback compared to older Intel versions.
- MacBook Air models provide consistent 18-hour battery life across M1-M5 chips, while actual performance varies based on usage patterns and processor workload.
Measuring MacBook battery life in straight hours of real-world usage (as Apple likes to do) is not always an accurate metric for comparison purposes as so many use and environmental factors play a part. We can, however, rely on straight technical specifications to tell us the stated battery capacities of each MacBook.
Where Apple is secretive about iPhone battery specifications (see our list of iPhone battery capacities based on teardowns), the company does list MacBook capacities in Watt hours (Wh). We have trawled through the Apple product Tech Specs pages from 2009 to 2025 to bring you as complete a list as we can gather using official Apple battery declarations.
The watt-hour is a unit of energy equivalent to one watt (1W) of power utilized for one hour of time. it is calculated by multiplying the number of Amps with the battery voltage. The higher the number of Wh the longer a battery will last using the same application. Batteries will lose efficiency over time so don’t expect a 2009-era MacBook battery to still possess the same power as it did when it was new or more than a 2025 model, even if it had an originally higher Wh rating.

Our list includes older MacBooks that used an Intel processor, and works its way to the latest M-series (for example, M1, M2 Pro, M3, M4, M5) MacBooks. The MacBook Neo with its A18 Pro chip starts us off.

Does the MacBook Pro have a better battery than the MacBook Air?
As you can see from the above battery capacities, the MacBook Pro features higher capacity batteries than the MacBook Air, although not by a truly significant margin.
For example, the 13-inch M3 MacBook Air’s battery was rated at 52.6Wh, while the 13-inch M2 MacBook Pro had a 58.2Wh battery.
The larger the laptop, the higher wattage is the battery—as they generally require more power to run the larger, brighter screens. The Air features a Liquid Retina display with 500 nits brightness while the Pro has a superior 1,000-nit Liquid Retina XDR display.
The newer MacBooks with more efficient processors will also gain extra battery life by not stressing the batteries as hard to complete the same tasks.
Apple claims that the current 13-inch M5 MacBook Air (53.8Wh) boasts up to 18 hours Apple TV app movie playback. The 14-inch M5 MacBook Pro has a higher capacity 72.4Wh battery and can keep going for 24 hours on the movie playback. The 16-inch M5 Pro has the same 24-hour video playback claim despite its 100Wh battery but it has to run the larger screen.
Battery life depends on many factors, particularly which and how many applications you are running at one time.
