By ForGeeks
Apple has unveiled the iPhone Air with a battery of only 3149 mAh — and contrary to skepticism, the smartphone demonstrates outstanding battery life. In tests, the novelty surpassed the Samsung Galaxy S25 Edge, which has a larger battery of 751 mAh.

Battery life tests
YouTuber XEETECHCARE tested the iPhone Air on a full discharge cycle and recorded 8 hours and 57 minutes of active screen time. The Galaxy S25 Edge stopped at 8 hours and 45 minutes with a 3900 mAh battery.
Tom’s Guide got similar results. In a web-surfing test, the Air managed 12 hours and 2 minutes, while the Galaxy S25 Edge — 11 hours and 48 minutes. In video streaming, the iPhone’s advantage was even more noticeable: after 5 hours, it had 81% of its charge left, while Samsung’s — only 67%.
The Role of Optimization
Analysts note that Apple’s advantage is not only due to the A19 Pro chip, but also to software optimizations. Earlier, it was reported that the company has implemented an AI-based resource management system to improve energy efficiency.
In the XEETECHCARE tests, the iPhone 17 Pro Max (11 hr 53 min) beat the Galaxy S25 Ultra (9 hr 18 min), and the iPhone 17 Pro with a 3988 mAh battery beat last year’s 16 Pro Max with a 4685 mAh battery. All of this points to Apple’s serious progress in energy efficiency.
Insiders also note that Samsung probably won’t increase battery capacity in the 2026 Ultra flagship. That makes the upcoming competition with the iPhone 17 Pro Max even more interesting.
Total
The iPhone Air has shown that high battery life doesn’t always depend on battery size. The smartphone, which was criticized for «having too small a battery» turned out to be more resilient than a competitor with a noticeably larger capacity.
For those who doubt the device’s durability, YouTuber JerryRigEverything has already tested how difficult it is to bend the new product.
