Samsung Galaxy S25 Edge review

Bright 6.7-inch LTPO OLED display

The Galaxy S25 Edge features an LTPO OLED panel with the exact resolution as the S25 Ultra - 1440 x 3120px. It's just that it's 0.2" smaller and matches the Plus' diagonal of 6.7". The device also doesn't skip features like granular refresh rate control with up to 120Hz and HDR10+.

Unfortunately, Dolby Vision is still missing from the feature list (Samsung is never getting on board that train), and the color depth is 8-bit, not 10-bit. That's hardly an issue for most users, but color gradients may not appear as smooth as on a true 10-bit display.

Performance-wise, the display isn't much different from the S25 Ultra. It can go up to 768 nits in manual mode and boost up to 1,416 nits in auto mode. That's more than enough for comfortable outdoor use even on a bright sunny day.

Refresh rate

Like the rest of the Galaxies, the S25 Edge offers Standard and Adaptive refresh rate modes. However, both modes seem to be adaptive in a way, meaning the display will dial down to 1 Hz when idle, but the Adaptive one boosts up to 120Hz, while the Standard is capped at 60Hz.

Additionally, video 24fps and 48fps video playback in Standard mode is locked to 60Hz, while Adaptive matches the refresh rate.

Battery life

The Galaxy S25 Edge relies on a relatively small 3,900 mAh battery that powers the Snapdragon 8 Elite and a 6.7-inch LTPO OLED. And frankly, we expected battery life to be abysmal. However, it's nowhere nearly as bad as we imagined.

Sure, Acitve Use Score of 12:06h isn't something to brag about, but it's not too far from some competitors, like the Google Pixel 9 Pro XL, for example, and it even matches some midrangers, which tend to have longer battery life than flagships.

Of course, compared to the rest of the Galaxy S25 family and alternatives such as the iPhone 16 Pro Max, the vivo X200 Pro, or the Xiaomi 15 Ultra, this thin handset falls behind. Interestingly enough, the Edge holds up pretty well in the video playback test.

Charging speed

Unlike the Galaxy S25+ and S25 Ultra, the S25 Edge caps its charging rate at 25W using a Power Delivery charger with Samsung's PPS protocol. Wireless charging is, as usual, rated at 15W.

The charger isn't provided in the box, so you'd have to buy a compatible one to make the most of it.

Since the Galaxy S25 Edge has a similar battery capacity to the vanilla S25 and supports up to 25W charging, it's not a surprise that the results are very similar. The S25 Edge outperforms the S25 by a small margin at the 15 and 30-minute marks, but charges significantly faster to 100%. In fact, the S25 Edge gets pretty close to the S25+ charging time to 100% (1 hour and 4 minutes for the Edge vs. 59 minutes for the S25+ with a 45W charger).

When pitted against the competition, however, the S25 Edge charging speed is far from impressive. Only Pixels and iPhones have similar charging times.

Even though it's not the fastest to charge, the S25 Edge provides some battery health-preserving options. You can disable fast charging or you can limit the charging to anything between 80 and 95%.

Speakers

The Galaxy S25 Edge offers a hybrid set of stereo speakers - one full-fledged speaker placed at the bottom and another one with a double duty as an earpiece at the top.

Loudness is rated as "Good" at -26.4 LUFS but lower than the rest of the S25 lineup. That's expected given the thin profile of the chassis. Less room means less loudness.

Less room also means less bass, though; you can clearly hear the difference. The sound tuning is very similar to that of the S25 Ultra, but the tracks sound flatter with not-so-pronounced bass.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
