Did you heave your Droid RAZR through a metropolitan area in an attempt to recreate the lamppost slicing skills Motorola showed in their commercials? No? Well, even if you only dropped your phone down a couple flights of stairs, this guide will show you how to replace the battery assembly.
Step 1 — Back Cover
Insert a plastic opening tool between the back cover and rear case at the lower left edge of the back cover. Pry the back cover up with the plastic opening tool to free the plastic clips. Continue prying along the left edge of the back cover towards the top of the phone.
Step 2 Work the plastic opening tool across the top of the back case to free the plastic clips. The top edge of the back case is very thin. Pry carefully to avoid cracking or snapping it. Continue prying down the right side of the back cover to free the remaining clips
Pull the back cover away from the phone to remove it.
The back cover is attached to the battery with a generous amount of adhesive, so you may have to use quite a bit of force to separate the two pieces.
Since the back cover is made of Kevlar, it can handle a fair amount of twisting and tugging without breaking.
Step 4 — Battery Use the tip of a spudger to lift up the red silicone cover over the battery terminal screws and remove it.
Step 5 Remove the two 3.3 mm T5 Torx battery terminal screws. Grab the blue battery removal tab and lift the battery out to remove it. There is quite a bit of adhesive securing the battery to the motherboard. Work slowly to avoid deforming the battery. Your phone will have a number of metal EMI shields on the motherboard, rather than the bare ICs seen here.
Now you can replace battery for your Droid Razr. And don't forget how to reassembly it. If you like, you can also replace the battery with Razr Maxx's one.
