Galaxy S25 Edge vs iPhone Air: Which Ultra-Thin Phone Should You Buy in 2025?

In 2025, both Samsung and Apple finally went all-in on ultra-thin flagships. Samsung has the Galaxy S25 Edge, and Apple has the iPhone Air. If you’ve held either one in person, you know how shocking they feel in the hand: almost impossibly slim, but still flagship-level.

If you love thin phones but don’t know whether to go Samsung or Apple, this guide breaks things down with real numbers: thickness, weight, battery capacity, performance, price storage options, charging speeds, network requirements, camera hardware, and early reviews. If you can test them in a store, do it—this article will help you walk in with a clear checklist.

1. Specs at a Glance

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:

• Galaxy S25 Edge: 256GB / 512GB

• iPhone Air: 256GB / 512GB / 1TB (better for creators or users who store large photo/video libraries)

Charging differences:

• S25 Edge: Up to 25W wired + Qi wireless

• iPhone Air: Around 20W wired + strong MagSafe / Qi2 support

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.

4. Camera Setup & Shooting Style

The S25 Edge includes a more versatile dual-camera system:

• 200MP main + 12MP ultrawide

The iPhone Air keeps things minimal:

• 48MP main camera only

This doesn’t mean poor quality — the Air still captures excellent everyday photos, and Apple’s widely praised computational photography continues to deliver some of the most natural and refined images in the industry.

5. Price Comparison (U.S. Market Reference)

Galaxy S25 Edge

• 256GB — $1,099

• 512GB — $1,219

iPhone Air

• 256GB — $999

• 512GB — $1,199

• 1TB — $1,399

All pricing is based on U.S. retail reference.
The iPhone Air starts at a lower entry price and provides a larger 1TB storage option, while the Galaxy S25 Edge costs slightly more but offers a bigger battery and a more versatile camera system.

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.
