Mi 9 was released at the end of February and was Xiaomi's first flagship model in 2019. Despite its sleek design, powerful hardware configuration, three-camera 48MP camera on the back with imaging capabilities impressive, but this phone comes with a fairly modest battery with a capacity of only 3300mAh.
If you own a Xiaomi Mi 9 and feel the 3300mAh battery is still not enough, this may be the right solution for you. More specifically, a retailer on Taobao (e-commerce website in China) is providing a "battery level" service that promises to increase Mi 9's battery capacity.
The retailer will proceed to replace the 3300mAh zin battery with a 6500mAh battery, or even 9900mAh if you want. However, replacing a larger capacity battery also affects the weight and thickness of the device, making it 3.4mm thicker and 60g heavier.
Looking at the image below, it can be seen that the Mi 9 after the "battery level" looks quite thick. Even, the rear camera group made by Xiaomi protruding from the back is now well below. Clearly, a large battery capacity will give users a longer usage time, but you have to trade many things, especially aesthetics.

In addition to the large capacity "battery", the service provider said the device's features will remain unchanged, even supporting wireless charging like other normal Mi 9s. .
