Xiaomi Redmi Note 4X Battery Replacement

The first thing we have to do is use a pry tool to remove the back cover (make sure to remove the sim tray first)

Now we have to remove the battery, luckily the Battery can be removed first after taking the back cover off.

Now you can insert your new battery, pop the back cover on, and your good to go! Congratulations, you've just replaced your phone's battery.
