2. Thickness, Weight & Battery Life
When it comes to thinness, the iPhone Air is slightly slimmer at 5.6 mm, offering a sleeker in-hand feel. The Galaxy S25 Edge is a bit lighter, though the difference is negligible in daily use.
Where Samsung pulls ahead is battery life:
-
S25 Edge: 3,900 mAh
-
iPhone Air: 3,149 mAh
If you want the thinnest possible device, the iPhone Air has the edge — but if battery endurance matters more, the S25 Edge is the clear winner.

3. Performance, RAM Behavior, Storage Options & Charging
The real deciding factor for many users is the system experience — iOS vs Android. That alone can determine which device feels more natural to you.
Both phones come with 12GB of RAM, but they manage memory differently:
-
Samsung relies on Android’s flexible RAM allocation, ideal for multitasking and background processes.
-
Apple uses tighter iOS memory optimization, often achieving similar smoothness with fewer system resources.
Storage options vary more noticeably:
Charging differences:
If you value large storage and magnetic wireless charging, the iPhone Air stands out.
If you prefer faster wired charging and Android flexibility, the S25 Edge fits better.

6. Final Recommendation
-
Choose iPhone Air if you want the thinnest design, MagSafe convenience, Apple’s ecosystem, and a 1TB storage option.
-
Choose Galaxy S25 Edge if you need better battery life, camera versatility, faster wired charging, and Android flexibility (including physical SIM).
Both are excellent ultra-thin flagships — your choice depends on whether you prioritize ecosystem, endurance, or camera flexibility.
