Currently, everyone is talking about iQOO 15 Ultra and how it may change the gaming experience. Some people are also comparing it with the Vivo X300 Pro 5G phone.
Here, I have provided a detailed comparison between these two phones based on their performance, battery pack and charging speed, camera, display, design, and other factors, so you will get clarity on which one will be best for you when it comes to gaming and heavy performance in 2026.
Which One Is the Better Gaming Phone?
The Vivo X300 Pro 5G phone is powered by the MediaTek Dimensity 9500 chipset, which is undoubtedly a powerful processor. It provides smooth performance in daily use and in demanding tasks such as gaming. It comes with up to 16 GB RAM and up to 1 TB of UFS 4.1 storage.
On the other hand, the iQOO 15 Ultra phone is expected to be powered by the more powerful Qualcomm Snapdragon 8 Elite Gen 5 chipset. It will come with 16 GB RAM and up to 512 GB of UFS 4.1 storage. It is rumored to score over 4.5 million points on AnTuTu benchmarks.
Leaks also suggest that it will have an integrated active cooling fan and physical shoulder triggers, which are essential for gaming. So, if you are particularly looking for a gaming phone, then you should definitely wait for the iQOO 15 Ultra phone to launch.
Battery Pack
Battery life is also essential in a gamer’s life. The Vivo X300 Pro 5G phone comes with a 6,510 mAh battery pack, and it supports 90 W wired and 40 W wireless charging.
The iQOO 15 Ultra phone is expected to feature a larger 7,000 mAh+ battery pack, and it may support faster 100 W wired and 40 W wireless charging.
Camera Setup
In the camera section, I would go with the Vivo X300 Pro 5G phone because it features a versatile 50 MP main sensor with OIS, a higher-resolution 200 MP periscope telephoto lens with 3.7x optical zoom, and a 50 MP ultra-wide camera. In front, it also has a 50 MP selfie camera.
On the other hand, the iQOO 15 Ultra phone features a triple camera setup, which includes a 50 MP main sensor with OIS, a 50 MP 3x periscope telephoto lens, and a 50 MP ultra-wide camera. Whereas in front, it is equipped with a 32 MP selfie camera.
