Introduction

This guide shows how to open the Motorola Moto Z in order to replace an old or dead battery.

Before you begin, discharge your battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

If your battery is swollen, do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

The display assembly is extremely fragile and has no reinforcement. Work slowly and methodically when handling the display assembly.

Heat an iOpener and apply it to the left edge of the phone for at least 90 seconds.
  • Heat an iOpener and apply it to the left edge of the phone for at least 90 seconds.

  • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

  • As you're waiting for the adhesive to soften, move on and read the following step to get an idea of where to pry.

Apply a suction cup as close to the heated edge as possible. Lift on the suction cup and insert the tip of an opening pick into the gap. Do not insert the pick more than 1/16" (1.5 mm). Doing so may damage the OLED panel.

Carefully slide the tip of the opening pick down and up the side of the phone, making sure not to cut deeper than 1/16" (1.5 mm). As you run the pick along the side, you will feel the tip of the pick press against the edge of the OLED panel. That is as far as the pick should go without damaging the panel. Once you have separated the adhesive, leave an opening pick in the side to keep the adhesive from resealing.

    • Remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • Secure the new battery with double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone, not directly onto the battery. The adhesive should go on the silver, exposed part of the battery compartment, not on the black foam layer.

    • Press the battery firmly into place for 5-10 seconds.
