Someone gave this old phone a cooling fan and 9,900mAh battery

Gaming phones are pretty commonplace these days, as the likes of Asus, Black Shark, Nubia, and Xiaomi all offer them. What if you don’t want to spend a ton of money on a gaming phone but still want a powerful, long-lasting device for gaming?

Well, YouTuber GeekerWan has extensively modified a Xiaomi Mi 9, bringing a cooling fan, much bigger battery capacity, and more to the 2019 flagship phone. More specifically, the YouTuber added the fan, tripled the battery capacity to 9,900mAh by adding two more 3,300mAh batteries, removed the camera modules, and put it all in a 3D-printed case.
