iPhone Air battery exceeds expectations when compared to Galaxy S25 Edge

The iPhone Air unexpectedly scored points with impressive actual battery life, even surpassing its big rival, the Galaxy S25 Edge, surprising users.

According to Tom's Guide, the iPhone Air attracted attention right from its launch thanks to its thinness of only 5.6 mm - a rare number on a smartphone. This ultra-thin design has many people worried about battery capacity and the ability to maintain use in practice.

However, the test results brought a surprise when the iPhone Air was still able to operate for a full day. However, to achieve the record thinness, Apple had to trade off a few factors compared to the more advanced versions, something users should consider before choosing.

According to the latest review from Tom's Guide, the iPhone Air has just undergone an intensive battery test to verify Apple's "all-day use" claim. The test was conducted under conditions of continuous web surfing on a 5G network, with the screen brightness kept at 150 nits. The result surprised many people when the device lasted for 12 hours and 2 minutes.

iPhone Air unexpectedly scores with impressive actual battery life

With this number, the iPhone Air has proven its ability to surpass the Galaxy S25 Edge – a direct competitor from Samsung – which only reached 11 hours and 48 minutes. Even the battery life of the device is close to the standard iPhone 17, the difference is not too big when this model reaches 12 hours and 47 minutes.

However, when compared to the iPhone 17 Pro Max, the gap becomes clear. This high-end version recorded 17 hours and 54 minutes, which is nearly 6 hours more than the iPhone Air. This shows that although the iPhone Air makes a strong impression in the thin and light segment, users still have to accept the trade-off if they prioritize battery life.

However, in another real-life test with YouTube, the iPhone Air continues to surprise with its battery capacity. During 5 hours of continuous video playback, the device still retains 81% of its battery capacity. This number shows that Apple's energy optimization ability has been significantly effective.

Galaxy S25 Edge is considered a strong competitor to iPhone Air

If calculated based on the above results, the iPhone Air can completely reach more than 26 hours of continuous video playback. This far exceeds the 22 hours that Apple itself announced. Meanwhile, the Galaxy S25 Edge – the biggest competitor – only has 67% battery left after the same period of use, showing a clear difference.

Technology experts say the iPhone Air has cleverly balanced an impressive ultra-thin design with a battery powerful enough to meet real-world needs. This is a testament to Apple's ability to optimize internal space, making the product both slim and durable.

With such battery life, the iPhone Air becomes the ideal choice for those who want a smartphone that is delicate, light but still feels secure when used all day long. This balance makes the device stand out in the slim design segment.

However, when it comes to battery life alone, the iPhone 17 Pro Max still holds the number one spot. With its superior capacity and long operating time, it is still the top choice for those who consider battery life the most important factor.
