Battery and thermal rivalry
Thermal management issues affect both devices because of their slim builds. The iPhone 17 Air uses the A19 Pro chip, but it throttles performance to prevent the frame from becoming a hand-warmer. The Samsung Galaxy S25 Slim uses the Snapdragon 8 Elite for Galaxy, and it also throttles performance during sustained workloads. During one hour of 4K 60fps video recording, the iPhone 17 Air lost 40% of its battery. The Samsung Galaxy S25 Slim provides better battery life in several tests. The Samsung device lost 18% of its charge during intensive benchmarking, while the iPhone 17 Air lost 15% during the same test. The Samsung S25 Slim delivers better endurance than the iPhone 17 Air because its 3900mAh battery lasts longer than the 3149mAh cell found in the Apple device during extended video playback sessions. The Samsung device achieves 7 hours and 48 minutes of screen-on time, while the iPhone 17 Air achieves 7 hours and 15 minutes. The Samsung device supports 25W wired charging, whereas the iPhone 17 Air supports 20W wired charging.
Camera and hardware comparison
