Design and Size
The S25 is a true compact flagship
The Galaxy S25 is all about compact minimalism. It weighs just 162g and measures a sleek 7.25mm in thickness — one of the slimmest flagship phones in years. Apple’s iPhone 17 is catching up in some ways but is still said to remain heavier and thicker.

Apple is said to be testing new green and purple shades alongside black, white, steel gray, and light blue. Samsung, meanwhile, offers Icy Blue, Mint, Navy, and Silver Shadow.
Display Differences
Samsung’s Galaxy S25 uses a 6.2-inch AMOLED panel with a 120Hz refresh rate and a measured peak brightness of around 2,600 nits — slightly ahead of Apple’s estimated 2,000–2,200 nit target.

Both phones feature symmetrical bezels, and Apple is said to have decreased them with the iPhone 17. Apple will continue to rely on Face ID via the Dynamic Island for biometrics, while Samsung offers an ultrasonic fingerprint scanner and basic Face Unlock.
Performance and Software
Snapdragon 8 Elite vs A19
The Galaxy S25 is powered by the Snapdragon 8 Elite — one of the fastest smartphone chips on the market. Apple’s iPhone 17 will counter with the A19 chip built on TSMC’s upgraded 3nm process (N3P), though performance gains over the A18 may be modest.

Camera
Apple still won’t offer a dedicated telephoto camera
| iPhone 17* | Galaxy S25 |
|---|---|
| Main 48 MP, f/1.8 24 mm 1/1.28″ sensor size |

*Expected/rumored
The big news for Apple is the new 24 MP selfie camera — a leap in resolution that could improve video calls and recording content for social platforms. Samsung’s camera hardware remains unchanged from the S24, but software enhancements like Log video and Audio Eraser make a difference in real-world use.
Battery Life and Charging
Small bump for Apple, familiar story for Samsung
The iPhone 17 is expected to have a slightly larger battery than the iPhone 16 — around 3,877 mAh — which is still smaller than the S25’s 4,000 mAh unit. However, Apple may finally be increasing wired charging speeds up to 35W and enabling 25W wireless charging via third-party Qi2 charging devices.
| iPhone 17* | Galaxy S25 |
|---|---|
| Battery size ~3,877 mAh |
Battery size 4,000 mAh |
|
Charging speeds 25W wireless charging USB-C 3.2 |
Charging speeds 25W wired 15W wireless charging USB-C 3.2 |
*Expected/rumored
If Apple manages to deliver faster charging and improved efficiency via the A19 chip, battery life could finally match or surpass Samsung’s in real-world use.

*Expected/rumored
Summary
But the iPhone 17 finally closes the gap in key areas: 120Hz display, faster charging, and a much better selfie camera. If Apple keeps the price close to $799, it may be the most well-rounded base iPhone we’ve seen in years.
Ultimately, this showdown comes down to priorities. If you value performance and the benefits of a telephoto camera, the Galaxy S25 is the better pick. The iPhone 17, however, is a much better challenger to Samsung’s base flagship than its predecessors were, largely thanks to the screen quality and battery life that might finally catch up.
