The Galaxy S25 is the slimmer and lighter smartphone of the two. However, it also has a slightly smaller screen (something to keep in mind).
Design
Both flagships have a punch-hole screen and minimal (symmetrical) bezels on the front. On the back, the Xiaomi 15 houses a blacked-out rectangular camera island, while the Galaxy S25 features three lenses protruding from the otherwise uniform back panel. Moreover, both phones follow a minimal design language with premium materials and finish.

Xiaomi 15 vs. Galaxy S25: Display
The Xiaomi 15 houses a 6.36-inch LTPO 120Hz screen with a resolution of 2,670 x 1200 pixels (460 ppi) and a peak brightness of 3,200 nits (25% of the display area). The 12-bit screen can produce 68 billion colors, has a touch sampling rate of up to 300Hz, and supports 1,920 PWM dimming.
Regarding high dynamic range content, the screen is compatible with HDR10, HDR10+, and Dolby Vision content. It also comes with Low Blue Light, Flicker Free, and Circadian Friendly certifications from TUV Rheinland.
On the other hand, the Galaxy S25 sports a slightly smaller 6.2-inch LTPO 120Hz AMOLED 2X screen with a resolution of 2340 x 1080 pixels (416 ppi) and a peak brightness of 2,600 nits. The 8-bit panel can produce 16 million colors and has a touch sampling rate of up to 240Hz. However, it doesn’t support PWM dimming.
The handset’s screen can play HDR10+ content but doesn’t support Dolby Vision. Clearly, Xiaomi has added more features to the Xiaomi 15’s screen, making it a better smartphone screen.
Xiaomi 15 vs. Galaxy S25: Performance
Both the flagships run on Qualcomm’s latest 3nm mobile platform, the Snapdragon 8 Elite SoC. While the chipset’s standard variant on the Xiaomi 15 features two prime cores clocked at 4.32 GHz, the overclocked version on the Galaxy S25 has two 4.47 GHz prime cores.
This might give the Galaxy S25 a slight advantage, but we’ve seen smartphones with Snapdragon 8 Elite’s regular version do better on benchmarks, so we’d like to wait for Xiaomi 15 to appear on GeekBench 6 or AnTuTu 10 before commenting on the same.
Xiaomi has released its latest flagship in one memory and storage variant: 12GB (LPDDR5X) + 512GB (UFS 4.0). In contrast, the Galaxy S25 is available in two memory/storage variants: 12GB + 256GB and 12GB + 512GB (both with LPDDR5X RAM and UFS 4.0 storage).
Besides, both phones feature the Adreno 830 GPU that supports hardware-accelerate ray tracing for realistic lighting and shadows in video games. In simpler words, you should be able to run popular mobile titles like Battlegrounds Mobile India or Call of Duty: Mobile in higher graphics settings without any issues.
Last but not least, the chipset features the Hexagon NPU for handling on-device AI features. Both phones have a heat dissipation system for sustained performance, too. All in all, the handsets are equipped with one of the fastest processors for Android smartphones and should provide top-tier performance, enough to handle heavy multitasking or video editing.

Apart from this, Xiaomi has promised to provide four years of major operating system and six years of security updates for the handset.
Conversely, the Galaxy S25 runs on the One Ui 7.0 (based on Android 15), offering many customization options and other UI improvements. However, its biggest highlight remains a comprehensive list of Galaxy AI features: Live Translate, Generative Edit, Note Assist, Instant Slow-Mo, Generative Wallpaper, and cross-app multimodal Gemini voice assistant.
In addition, Samsung promises to support the Galaxy S25 with seven years of operating system and security updates. So, if longevity is your priority, the Galaxy S25 should be among your top considerations.
