Danger

Introduction

If the battery on your phone doesn’t seem to hold a charge like it used to, it might be time to replace it. Follow this guide to replace your battery.

Warning: Because of the strong adhesive securing the display, minimal clearance for inserting your tools, and high heat required, there's a good chance of accidentally damaging the display during this procedure. If you're replacing the display anyway, then you don't have to worry—but for all other repairs, work very carefully, and be prepared to replace the display afterward if necessary.

Power your phone off before you begin.
  • Power your phone off before you begin.

  • If possible, drain the battery before disassembly. When the battery is charged, there's increased risk of a dangerous thermal event if the battery is overheated or damaged during repairs.

  • If your display is cracked, completely cover it with packing tape to contain the glass shards and avoid injury.

Prepare an iOpener and heat the front of the phone along its left edge for about two minutes, or until it's slightly too hot to touch. This will help soften the adhesive securing the display.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

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

  • In the following steps, you will separate the display assembly from the Moto Z Play's chassis.

    • For reference, refer to the first image, showing the back of the display assembly (right) after it has been removed from the phone (left).

    • If you plan to re-use the display assembly, pay particular attention to the side edges. When slicing through the glue in this area, you must be careful to insert your tool less than 2 mm, or your tool will come in contact with the display panel and damage it.

    • Playing cards are a safer, but much slower, prying tool. The soft paper cards are less likely to damage the display panel, which is good news if you plan to reuse it.

  • Apply a suction cup to the display, near the middle of the left edge.

  • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • If the screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

  • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool.

  • If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

Add Comment

  • Insert an opening pick (or playing card) into the gap you opened behind the display.

Add Comment

  • Slide the tool all along the left edge of the phone to slice through the adhesive securing the display.

Add Comment

  • Heat the front of the phone between the display and the lower edge to soften the adhesive underneath.

  • Slice through the glue under the lower bezel, being careful not to damage the fingerprint sensor.

  • Slide or roll your tool past the lower edge of the fingerprint sensor and continue to the other side. Do not pry directly underneath the sensor.

  • If you plan to re-use the display, be careful not to slice or pry at the display panel. Refer to this image to help identify the glued areas while avoiding the display panel (highlighted in red).

  • Insert your tool at the top right corner of the phone, and begin to slide it underneath the top bezel to separate the glue.

    • As before, if you want to re-use the display, don't insert the tool far enough to touch the display panel.

  • When your tool just passes the left edge of the earpiece speaker, stop.

  • Slide or roll your tool over the top of the flash module for the selfie camera to avoid damaging it.

  • If the display remains stuck, re-heat and slice the adhesive repeatedly as needed.

  • Lift the display from the left edge and swing it open, away from the phone.

  • The battery is strongly glued into place.

  • If available, apply some high concentration (>90%) isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

  • Alternatively, apply a freshly heated iOpener to the back of the phone directly behind the battery for two minutes to help soften the adhesive. Re-heat and reapply the iOpener as necessary.

  • When using tools to pry up the battery, be careful not to damage the two orange flex cables hidden underneath the battery's top edge.

  • Insert several opening picks or a plastic card along the outer edge of the battery.

  • Apply steady, even pressure to slowly lever the battery up and out of the phone.

    • If necessary, use several rounds of heating and pressure to slowly weaken the adhesive, and the battery will begin to separate.

    • Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

    • If you're reinstalling your existing display, remove all the old adhesive from that as well.

  • Use the point of your spudger to scour away and remove any smaller bits of adhesive that remain stuck.

    • Be extremely careful not to accidentally puncture the battery with your spudger.

  • For best results, clean the area underneath the removed adhesive with isopropyl alcohol to help prep the surface so the new adhesive bonds more strongly.

  • The pre-cut adhesive sheet for the display contains three layers: a plastic liner (usually blue), an adhesive layer in the middle (black), and a wax paper liner (white).

  • Peel away and remove both the white paper liner and the black adhesive layer from the center section of the adhesive sheet.

    • When you're done, the adhesive sheet should look like the third image.

  • Before sealing the display in place, connect the flex cables for the display and fingerprint sensor, and then power your phone on.

  • Test all functions to make sure your repair was successful before sealing up the display.

  • When fully inserted, the white line across each flex cable should be even with the markings on the motherboard on each side of the cable.

  • Do not remove, insert, or adjust the cables while the phone is powered on.

  • The cables can be tricky to align and install. Be sure not to touch the gold contacts on the back, or your finger oils may cause a malfunction. If you do accidentally touch them, wipe them gently with isopropyl alcohol.

Add Comment

  • When your repair is tested and complete, press the display firmly into place and remove any plastic liners from the screen.

  • To help the display adhesive bond more securely, heat the perimeter of the display and then place the phone under a heavy stack of books for 30 minutes.

Good instructions. 2 things to add. Be careful how much heat you apply, I damaged my screen. A real heat gun needed about 30 seconds. Second is you can get custom cut stickers for the Z play to reinstall the battery and screen they are from that big online company, you know the one.
