iPhone Air and Galaxy S25 Edge, which one has better battery?

Since its launch, durability and battery life have been two important factors that customers consider when buying the iPhone Air. Users have been able to verify its ability to withstand pressure when dropped or through experiments from the brand.

In a test by Bgr, with a thickness of only 5.65 mm, the glass can break if dropped carelessly, but the phone does not bend. In terms of battery life, users can use it all day without charging.

Although at a decent level, the battery life of the iPhone Air still cannot be compared with the iPhone 17 or 17 Pro Max which have a thicker design and larger battery compartment. Because the iPhone Air is a special smartphone line, it prioritizes a thin and light design.

So, YouTube channel PhoneBuff compared it to similarly slim phones, including the Samsung Galaxy S25 Edge. Previously, the channel demonstrated that the iPhone 17 Pro Max has better battery life than the Galaxy S25 Ultra and Pixel 10 Pro XL despite being similar in size.

The Galaxy S25 Edge is slightly thicker at 5.8mm. The Samsung display is 6.7 inches, compared to the iPhone Air's 6.5 inches. This gives the Galaxy S25 Edge a larger overall footprint, enough to accommodate an additional secondary camera and stereo speakers inside. The phone also has a larger battery (3,900 mAh) compared to the iPhone Air's 3,149 mAh.

Phonebuff used a series of pre-programmed tests. The test used a robotic arm to control the phone, rather than a human, to ensure objectivity. Each device ran the same app for an hour, going through tasks such as: calling, texting, emailing, surfing the web, Instagram, watching YouTube, playing games, using GPS for directions, listening to music via Spotify, and taking photos with Snapchat.

With significantly higher specs, it's no surprise that the Galaxy S25 Edge won. However, the difference was only one minute. Specifically, the Galaxy S25 Edge lasted 25 hours and 59 minutes, while the iPhone Air shut down just one minute before. The test also included 16 hours of standby time, to assess each device's ability to save energy when not in use.

During the test, the Galaxy S25 Edge was ahead of the iPhone Air for most of the test, with a higher battery level remaining after each task. The Samsung also used less power in standby mode. Interestingly, the iPhone Air caught up in the hardware-intensive tests, including gaming and taking photos with Snapchat.

This head-to-head comparison shows that the most premium ultra-slim smartphones today all have similar battery life. Users who are not too loyal to a brand or operating system can easily choose to change providers. However, the premium ultra-slim phone market is now almost limited to these two options.
