Slim Phone Showdown: iPhone Air and S25 Edge Measured
27 Apr
Summary
- iPhone Air body is 5.64mm thick, S25 Edge is 5.8mm.
- Both thin phones sacrifice battery life for their slim design.
- Foldables from Chinese companies are thinner when opened.
The quest for the thinnest smartphones continues with Apple's iPhone Air and Samsung's Galaxy S25 Edge. The iPhone Air boasts a body thickness of 5.64mm, narrowly beating the S25 Edge at 5.8mm. This pursuit of slimness, however, leads to a significant compromise: battery life. Both manufacturers admit that less internal space directly impacts power capacity.
While these phones are thinner than their standard counterparts like the iPhone 17 and Galaxy S25, they are still thicker than some open foldables from Chinese manufacturers. The combined thickness of the iPhone Air and S25 Edge is also greater than many standard flagship models. Both devices feature advanced displays and processors but users must weigh the sleek design against potential battery endurance concerns.
Despite the reduced battery capacity, both phones support fast charging, reaching approximately 50% in 30 minutes with a 20-watt or higher adapter. The iPhone Air is powered by the A19 Pro processor, while the S25 Edge uses a Snapdragon 8 Elite. Storage options range from 256GB upwards, with both phones running the latest iOS and Android operating systems respectively.
