Huawei Mate 8 Battery Replacement

Step 1 Back Cover



• Switch off your phone and remove the SIM card tray.
Step 2

• Remove the Torx T2 screws from the bottom of the phone
Step 3
• Use an iSclack or a suction handle in the bottom area of your phone to separate the display unit from the rear panel.
Step 4
• Use an opening pick to fully separate the clips, releasing the phone.
• Do not fully remove the rear case. The fingerprint sensor cable is still connected to the back cover.
• Open the phone like a book from the SIM tray side.
• Use a spudger, to disconnect the fingerprint sensor cable.
Step 5 Daughterboard interconnect cable
• Remove the liquid indicator sticker.
• Remove the Phillips #00 screw that holds down the metal shield.
• The metal shield is tightly held in place. If you try to remove it without holding it down on one side, it'll break easily.
• Use a spudger to remove the metal shield.
Step 6
• Use the flat end of a spudger to disconnect the display, daughterboard interconnect, and battery cables.
Step 7
• Remove the Phillips #00 screw that holds down the interconnect cable bracket.
Step 8
• Lift the coaxial connector off of its socket to allow access to the daughterboard interconnect cable bracket.
• Remove the bracket.
Step 9
• Use a spudger to disconnect the interconnect cable.
• Remove the interconnect cable.
Step 10 Battery
• The battery is glued in place with two adhesive strips. One with a pull tab and one without.
• Get a good grip on the pull tab near the power button and peel out the adhesive strip by steadily pulling at the tab in a flat angle.
• If the adhesive strip rips, grab and twist it around the tweezer tips a couple of times and then continue.
Step 11
• Do not bend or puncture the battery, damage to the cell can cause battery fires.
• Heat an iOpener and place it on the phone for about a minute to loosen the remaining adhesive.
• Carefully insert the flat end of a spudger to separate any remaining adhesive at the top of the battery.
Step 12
• Lift the top end of the battery to pull the battery off of the remaining adhesive strip.
• When reassembling your phone apply double sided adhesive tape or pre-cut adhesive to secure the new battery.
• Never reinstall a battery that has been bent or damaged during removal.
