The idea is that a three-year-old flagship smartphone has enough horsepower to run modern mobile games and can be bought second-hand quite cheaply. In this video, the Mi 9 with a cracked back was only bought for CNY 700 (roughly $107) and is perfect for converting it into a gaming phone. Basically, anyone wanting to find a cheap smartphone to do this should look for a Snapdragon 855-powered device with moderate community support should do nicely – something like a OnePlus 7T.
Smartphones designed for gaming have powerful technology, flashy designs, active cooling, and sometimes additional buttons to enhance the entire gaming experience on a smartphone. What if, on the other hand, you wanted to make your own? That’s exactly what Geekerwan, a YouTube channel, set out to do. In a way, yes. These guys took a Xiaomi Mi 9 with a Snapdragon 855 processor and heavily changed the hardware and software to turn it into a mobile gaming beast.
The cost of these tweaks is heat. So a custom thermal management system is in order. In its factory state, the smartphone is not optimized for extreme heat, which is why the camera module was removed and a heatsink with 40mm cooling fan was added with thermal compound. Of course, powering the fan will require tapping into the battery. In this case, a DC to DC converter board is added to regulate current to output 5V to the cooling fan. They even added switches to control the fan speed. Check out this souped up Xiaomi Mi 9 turned beastly gaming phone. Everything is wrapped into an SLA 3D-printed case to house the new brick, complete with universal bracket to mount that onto a game controller. Check out the video to see how the phone performed in benchmarks and stability tests.
The Mi 9’s 3,300 mAh battery isn’t going to cut it. So the battery is tripled by connecting them in parallel so the phone now technically has a 9,900 mAh battery – this will require modding the software to tell it how large the battery is. This involves knowledge with unlocking bootloaders and flashing aftermarket software. Check out this souped up Xiaomi Mi 9 turned beastly gaming phone. The next step is to overclock and overvolt the chipset. Flashing an aftermarket kernel makes it possible to even overclock the display to operate with framerates higher than intended by the factory.
Spoiler alert: it doesn’t disappoint. Genshin Impact – a heavily graphic-intensive game – averaged 39 frames per second before modifications with the highest settings. With the new mods, an average of 50fps was achieved.
