When you play heavy games like BGMI, PUBG Mobile, COD Mobile, or Genshin Impact, your phone’s processor works at maximum power. This generates a lot of heat, which can cause:
- Lag & frame drops
- Faster battery drain
- Thermal throttling (your phone automatically slows down)
That’s where a phone cooler fan comes in. These portable cooling devices attach to the back of your smartphone and use semiconductor cooling plates with fans to quickly reduce heat. Some even feature RGB lighting for a gamer look, or MagSafe compatibility for iPhones.
