Phones with the Best Cooling Systems for Genshin Impact

Taming the beast. We test which smartphones can maintain 60FPS in Genshin Impact without thermal throttling, thanks to advanced cooling tech.

Genshin Impact and Honkai: Star Rail remain the ultimate benchmarks for mobile gaming in 2026. While many phones can hit 60FPS for five minutes, very few can maintain it for an hour. The difference lies in the cooling system.

The Problem: Thermal Throttling

When a mobile processor hits a certain temperature (usually around 45°C), the system automatically reduces its clock speed to prevent damage. This results in "stuttering" or a sudden drop in frame rate.

1. RedMagic 9 Pro (Active Cooling)

The RedMagic 9 Pro is the only mainstream phone with a physical, 22,000 RPM fan inside. By moving air directly through the device, it keeps the Snapdragon 8 Gen 3 at its peak frequency indefinitely. In our tests, it maintained a perfect 60FPS for two hours with a surface temperature of only 38°C.

2. ASUS ROG Phone 8 Pro (Vapor Chamber + External Cooler)

ASUS uses a massive "GameCool 8" system with a 360-degree cooling layer. While it performs exceptionally well on its own, attaching the "AeroActive Cooler 8" external fan adds a thermoelectric (Peltier) cooling element that can drop temperatures by an additional 10°C.

3. Xiaomi 16 Pro (Loop LiquidCool)

Xiaomi has pioneered "Loop LiquidCool" technology, which uses a one-way heat pipe design to separate hot and cold liquid more efficiently than traditional vapor chambers. It is the best "standard" phone for gaming, avoiding the bulk of dedicated gaming devices.

Cooling Technologies in 2026

Vapor Chambers (VC): Large, flat plates filled with liquid that evaporates and condenses to move heat.
Graphite Sheets: High-thermal-conductivity layers that spread heat across the back of the phone.
Active Cooling: Physical fans or thermoelectric elements.

Sustained Performance Benchmarks (60m Playtime)

Model	Avg FPS	Max Temp	Throttling %
RedMagic 9 Pro	60.0	38°C	0%
ROG Phone 8	59.4	41°C	2%
Xiaomi 16 Pro	56.8	44°C	12%
iPhone 17 Pro	52.3	46°C	25%

Summary

If you are a hardcore Genshin Impact player, the RedMagic 9 Pro is the only device that offers a desktop-like sustained experience. For a more traditional flagship that still handles heat well, the Xiaomi 16 Pro is the top contender.
