1. Samsung Galaxy S25 Ultra

This year, Samsung’s flagship didn’t receive a warm welcome. The tech community seems to believe that Samsung has stopped innovating. The design is similar to the S24 Ultra, and the camera hardware is also identical. One UI 7 is also coming to older Samsung devices. So what’s new? Well, nothing else is new except for more AI and a newer chip with a better thermal design. Hands down, the phone is one of the greatest out there, but it feels repetitive.

Specifications 

  • Qualcomm Snapdragon 8 Elite for Galaxy processor
  • 6.9-inch Dynamic LTPO AMOLED 2X display with 120Hz refresh rate
  • 12GB RAM is standard and can be configured to 16GB RAM with 1TB storage
  • 200MP primary camera, 50MP ultrawide, 50MP telephoto with 5x zoom, 10MP telephoto with 3x zoom
  • 5000 mAh battery with fast charging
  • Android 15 with One UI 7.0 and seven years of software updates

2. iPhone 16 Pro Max

The same old trend applies to Apple, except that their battery backup is largely improved with the 16 Pro Max. Better processor, improved image processing, along with camera lenses. And yeah, we also have more AI on the Apple side of things. Everything else is pretty much the same, which can be found on the older models.

Specifications

  • A18 Pro Bionic processor
  • 6.9-inch ProMotion XDR OLED display with always-on functionality

Following Apple’s trend of the Pro Max, this is Pixel’s take on the same nomenclature; the Pixel 9 Pro XL is the largest variant on offer by Google. Sadly, the chip within it still falls way behind the likes of the competition. The cameras are great, but looking at the competition, it earnestly desires more. More AI as usual and better battery life. 

Specifications 

  • Google Tensor G4 processor
  • 6.9-inch LTPO OLED display with 120Hz refresh rate
  • 12GB RAM is standard and can be configured to 16GB RAM and 1TB ROM
  • 50MP primary camera, 48MP ultrawide, 48MP telephoto with improved zoom
  • 5060 mAh battery with fast charging
  • Android 15 with seven major Android upgrades

4. OnePlus 13

To some people, the OnePlus 13 is the ultimate smartphone of 2025, and there is a solid reason behind it. OnePlus has dramatically improved the overall performance of the phone. The cameras are great now, and it’s indistinguishable to the average person if a photo is shot on an S25 Ultra or a OnePlus 13. Of course, the S25 Ultra is better, but it’s nothing to write home about. What’s good is the thermal improvements of the OnePlus 13. As a result, it attracts quite a lot of enthusiastic gamers, making this device desirable in the performance segment. 

Specifications 

  • Qualcomm Snapdragon 8 Elite processor
  • 6.8-inch LTPO AMOLED display with 120Hz refresh rate
  • 12GB RAM is standard and can be configured to 24GB RAM and 1TB ROM
  • 50MP primary camera, 50MP ultrawide, 50MP telephoto with 3x optical zoom
  • 6000mAh battery with fast charging
  • OxygenOS based on Android 15

5. Asus ROG Phone 9 Pro

If your device requires additional cooling, you can purchase the AeroActive Cooler X Pro separately or as a bundle and attach it to your phone.

  • 6.78-inch LTPO AMOLED display with 185Hz refresh rate
