Introduction
Batteries are meant for reuse, but if they don't recharge then they may need to be replaced. This guide will show you how to safely remove your mobile device's battery.
What you need
-
-
Use a pin or paper clip to insert in the hole on the side of the phone next to the micro SIM cardholder to remove the tray.
-
Remove the SIM card tray from the Xiaomi Mi 4 and store it somewhere safe.
-
-
-
Using the flat metal spudger and curved metal spudger, make a wedge between the plastic back cover and the inner frame
-
Using the second spudger, slowly work your way around the perimeter of the device
-
As the back cover is almost completely removed, use the suction-cup tool to remove the plastic cover without damaging the back

Use a 000 phillips head screwdriver to remove the 10 1.2mm phillips head screws in the plastic frame that hold the motherboard and battery.
-
Use a 000 phillips head screwdriver to remove the 3 0.5mm phillips head screws in the plastic frame that hold the motherboard and battery.
-
Use the small plastic opening tool and place it in the slot on the bottom right corner of the inner frame and carefully pry it off.
I don't think it is necessary to remove the three 0.5mm screws. Note: the right-most orange circle should be placed instead of the red circle above the two larger orange circles - those are the 0.5mm screws which secures a small plate under the plastic cover which is in NOT physically (but electrically via two metal contacts) to the mainboard.

-
Use tweezers to gently disconnect the connections that run across the battery and are connected to the motherboard.
-
Proceed to gently remove the tape like connector from the battery until it is completely off.
-
Use tweezer to disconnect battery’s wire from the motherboard.
-
-
-
Use the plastic opening tool to gently pry the battery out of its casing for removal.
Using a Pry tool damaged a bit the casing of the battery. I ended up pulling the battery's plastic sticker to remove it (adhesive holding the battery in place)
Is it safe, can we fix the back cover perfectly?
