Use this guide to replace the battery in the Nexus 4's battery or to disconnect the battery before accessing the internal components. This short repair will only take a few minutes.

    • Remove the SIM tray using the SIM Card Eject Tool.

    • This step is required in order to remove the back case.

    • Gently open the back case by prying along the edge of the cover, starting at a corner of the phone and circling around the phone using a plastic opening tool.

    • The opening process may take a few minutes. The plastic will make a light snapping noise as the back cover separates from the rest of the phone.

    • Remove the two 1.8 mm Phillips screws holding down the battery connector.

    • Using a plastic opening tool, disconnect the battery cable from its socket on the motherboard.

    • Remove the blue tape that secures the white antenna cable to the battery.

    • Using a spudger, carefully disconnect the white antenna cable.

    • Carefully pry the battery out with a Plastic Opening Tool, starting at the top left-hand corner and working down towards the bottom right-hand corner.

      • If necessary, you can also use a plastic card to separate the battery from the metal midframe.

    • The battery is securely glued to the phone. When reinstalling the battery, press the battery firmly against the adhesive strip.


To reassemble your device, follow these instructions in reverse order. Start by seating the top of the back to the phone, then gently snap the back in place working from the top to the bottom.

I have made some arrangement to clarify particularly using pictures from the teardown that are just perfect. The original picture was not detailed and did not show the battery in place.

If you can't power on after battery replace:

Charge for an hour

Try holding down power plus volume down while plugging in power

If that doesn't work replug inside battery connector (this fixed for me)

Recommend data backup before in case you can't get it booting.

Just did this - thanks for all the instructions, easy if you have the right tools

followed these instructions and the device boots up OK but then immediately shuts down. getting into recovery mode and checking the logs I can see that the phone thinks the battery is over temperature (790C vs max of 68C). Hopefully it's just a poor connection where I fitted it. I'll take it apart and try again later.

Note that it is very easy to break a screw holding the battery connector - don't over tighten. I've managed to hold down the end of the connector, towards the center of the phone, with a washer fitted to a nearby screw. It's been working fine for 6 months
