How long does the MacBook Air M2 battery last? Apple claims the MacBook Air M2 has a battery runtime of up to 18 hours for movie watching. Below is a detailed review and tips to optimize the device’s battery life.
1. MacBook Air M2 Battery Specifications
The MacBook Air M2 and MacBook Air M1 have similar battery durations as per Apple’s specifications. The device specifically has the following features:
- Battery capacity: 52.6Wh
- Battery type: Lithium‑polymer battery
- Apple’s claimed usage time: Up to 18 hours watching movies on Apple TV and 15 hours of web browsing.
- Real-world usage experience of MacBook Air M2 Oneway: 14 hours of multitasking (browsing, movie watching, background music, office tasks, basic graphics).
The MacBook Air M2 battery duration, as announced by Apple, is equivalent to that of the MacBook Air M1.
Another significant factor affecting the MacBook Air M2’s battery life is its operating temperature. Upon actual testing, OneWay recorded temperatures close to 90 degrees, consistent with its M1 predecessor. This is also an acceptable temperature for laptop operations.
Despite having a smaller battery for its thinner size and a larger screen (13.6″ compared to 13.3″), the MacBook Air M2’s battery life is consistent with the MacBook Air M1 according to Apple’s data. Real-world usage is also similar to its predecessor (over 15 hours of multitasking compared to 14 hours).
Compared to the MacBook Pro M2, the MacBook Air M2 won’t have much difference in battery life.
2. Real-world Review of MacBook Air M2 Battery
To assess the MacBook Air M2’s real-world battery performance, OneWay designed a small experiment with the following setup conditions:
- MacBook Air M2, 8GB RAM, 100% new.
- Screen brightness: 80%.
- Keyboard brightness: Auto.
- Volume: 50%.
Starting conditions before the MacBook M2 battery test:
The battery test was as follows:
- 8:00 PM: Start the test – unplug the charger. Currently, more than 10 Safari tabs are open, and I’m listening to Spotify at 50% volume.
- 8:20 PM: Still at 100%, I switch the light to night mode.
- 8:30 PM: I’m browsing Facebook and casually reading online news, still listening to music, and not watching videos.
- 9:00 PM: Battery is at 96%. I feel like my MB Air M2 might last up to 25 hours continuously.
- 9:30 PM: An hour and a half has passed, and only 8% has been used (now at 92%).
- 10:15 PM: Finished web browsing, I switched to launching Photoshop. My MacBook operates smoothly.
- 11:59 PM: After nearly 2 hours of using Photoshop, my battery is at 75%.
- 12:15 AM: I want to watch some business videos on YouTube.
- 2:13 AM: The battery is at 60%. I let a continuous 10-hour video play and go to sleep.
- 8:15 AM: I wake up startled to see the battery at 25% and go back to sleep.
- 9:26 AM: I wake up again, and the battery is at 16%. I start reading some morning news, checking emails, and going through my start-of-day tasks using office apps like Google Docs and Excel.
- 10:40 AM: After finishing my morning tasks, my laptop’s battery is at 5%, and I plug it in to charge to prevent it from powering off.
In reality, the MacBook Air M2 battery lasted from 8:00 pm (100%) to 10:40 am the next day (5%), over 14 hours. This includes office tasks and basic graphics (Photoshop), less than the manufacturer’s specification (18 hours watching movies on Apple TV). However, this is an impressive duration for such a thin and light laptop like the MacBook Air M2.
3. Ways to Enhance MacBook Air M2 Battery Life
Although the MacBook Air M2 boasts impressive battery longevity, you can further extend its usage time with the following tips:
- Update to the latest software: Check and update by going to “System Preferences” > select “Software Update”.
- Turn off the keyboard backlight when not in use: Go to the Apple logo > select “System Preferences” > choose “Keyboard” > select “Turn keyboard backlight off after __ of inactivity”.
- Turn off Bluetooth when not in use: You can quickly turn it off by selecting the Bluetooth icon on the top right corner of the screen > select “Turn Bluetooth Off”.
- Regularly check battery status: Press and hold the Option key while clicking on the battery icon in the menu bar > see battery status under the “Condition” section.
- Quit unused applications: Click on the Apple logo > select Force Quit > close applications you aren’t using and that are running in the background.
- Always keep it charged: Regularly charging ensures that the current does not pass through the battery, reducing battery cycles and extending battery life.
- Regularly discharge the battery: Discharging the battery is a task that should be done periodically. This helps make the battery more durable and prevents the capacity from becoming constricted.
- Check battery usage cycles regularly: Select the Apple logo > choose “About This Mac” > under the “Overview” tab select “System Report” > choose “Power” to view the “Cycle Count”.
