Whether you want to buy the Xiaomi 15 Ultra or S25 Ultra, we just want to give you a heads-up that the Xiaomi 15 Ultra price in Pakistan is less than the S25 Ultra. Without wasting further time, let’s dive into it!

Two Flagship Phones, One Big Battle

The 15 Ultra of Xiaomi and the Samsung S25 Ultra are both from the premium phones of their brands. Both are beautifully designed, have outstanding displays, top-notch processors and features that sound futuristic. But when it comes to real-world usage in Pakistan, such as battery backup, daily performance, camera results and heat management, only one will become the winner.

Display and Design, WQHD vs LTPO

The 15 Ultra comes with a WQHD+ AMOLED display, which is 6.73 inches in size. It has Xiaomi Shield Glass 2.0 for pro-grade protection. The screen also offers peak brightness up to 3200 nits, which is excellent for the super clear visuals even under bright light conditions. And what should we tell you about its smooth 120Hz refresh rate? You have to try it out for yourself. The ultra-thin bezels give it a modern and premium feel.

On the other hand, the Galaxy S25 Ultra has a slightly bigger display: a 6.9-inch LTPO AMOLED 2X screen with only 2600 nits of peak brightness. It looks great, too and is protected with Gorilla Armour 2. Both phones have high refresh rates and sharp resolution. But Xiaomi’s brightness and colour performance give it a slight edge, especially in outdoor use in Pakistan.

Performance – Where Speed Meets Stability

The 15 Ultra is equipped with the latest Snapdragon 8 Elite chipset which is built on a 3nm process. The chipset offers blazing fast speeds up to 4.32GHz and the powerful Adreno GPU handles the graphics processing and rendering on the phone’s display. Due to the chipset phones handle heavy apps, games and multitasking like they are nothing. Xiaomi’s HyperOS 2 and HyperAI also optimize the phone for faster performance and smooth experience. 

Samsung Galaxy S25 Ultra uses a similar Snapdragon 8 Elite chip with a custom Oryon core. It’s fast too and works great with One UI 7 and Android 15. If we talk about better RAM management and quicker app launching, the 15 Ultra takes the lead with close calls.  Plus, the Xiaomi IceLoop cooling system helps it stay cooler during long usage.

Camera Showdown: Leica vs Galaxy

Everybody wants a perfect camera with their flagship devices! One of the most prominent things about the 15 Ultra is its camera setup. And with the marvelous 4 Lense camera, Leica has done it again! The phone comes with a 50MP Leica main sensor, a 200MP ultra-telephoto lens, a 50MP floating telephoto lens and a 50MP ultra-wide camera. Taking stunning shots with high clarity and amazing depth even when zoomed in, is not a problem for this phone. In short you have a DSLR in your hand due to what the camera system of 15 ultra can do. Also, it has a 32MP front camera for ultra-clear selfies. 

The S25 Ultra also comes with amazing camera lenses with somewhat similar mega-pixels as 15 Ultra; it includes a 200MP main camera, 50MP periscope telephoto, another 50MP ultrawide and a 10MP 3x zoom lens. The pictures are sharp, but the Samsung tends to add too much contrast and color in auto mode. It also has a 12MP front camera, which works fine but isn’t as detailed as Xiaomi’s selfie camera. In real usage, Xiaomi’s Leica partnership provides a better natural tone and pro-level camera features. So in terms of camera, Xiaomi takes the lead again.

Battery and Charging: Go Longer, Charge Faster

What’s a flagship phone for if it doesn’t have a long battery life! Many users in Pakistan often choose their new phones just on the basis of battery timing and these two phones won’t disappoint. The 15 Ultra has a non-removable 5410mAh battery. It easily offers you Up to 25 hours of video playback. The phone supports 90W fast charging with wire and also 80W wireless charging. Meaning you can fully charge your phone in just a few minutes and spend more time using it.

The Galaxy S25 Ultra is equipped with a 5000mAh battery. The phone also supports the fast charging of 45W (wired) and 15W with wireless charger. That’s good, but Xiaomi clearly offers better battery backup and much faster charging. For users who travel a lot or work outside, Xiaomi is the smarter choice.

Features That Make a Difference

Xiaomi 15 Ultra includes an ultrasonic in-display fingerprint sensor, AI Face Unlock, stereo speakers with Dolby Atmos and advanced cooling. It also has Wi-Fi 7, Bluetooth 6.0 and an IR blaster. The phone is IP68 water and dust-resistant, so it can handle daily wear and tear.

Samsung Galaxy S25 Ultra also offers water resistance, strong speakers and Samsung DeX for desktop experience. But the phone lacks fast charging support and advanced cooling as compared to the Xiaomi 15 ultra. Samsung’s S Pen (stylus) is a plus for professionals and students working on a project.
