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. If your battery is swollen, take appropriate precautions.

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.

  1. 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.

  2. 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.
    • 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.

  3. 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.

  4. 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.

    • 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.

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

    The repair kit that was bought for this phone came with the wrong size torx bit. Mine came with a T5 Torx which was bigger and I almost ruined the screw. I noticed it was not working and looked at the bit and in fact it was not the T3. Luckily I have the full kit and had a T3 Torx handy. Make sure to look at the Bits before using them. The screws are so fragile that they can get stripped easily.

    The kit comes with both a T3 and a T5—the T5 isn’t needed if all you’re doing is replacing the battery.

    • If the command strips break or the black pull tab is missing, you can still remove the battery using heat and/or isopropyl alcohol to weaken the adhesive.

    • 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.

  25. 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.

    Should the removal of the blue plastic backing wait until after verifying the screen works in the next step?

    Well, you can’t connect the screen with the plastic in the way. But in principle, you’re right—it wouldn’t be a bad idea to pause before installing the display adhesive, plug everything in, and verify that it works. Unfortunately, you then have to unplug it again to install the adhesive, so you’ll want to test it again once it’s plugged back in, but before sealing up your phone—just to make sure the cables are seated properly. So, the verification step is probably best left where it’s at.

    • 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.

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.

One of the best guides ever: clear and precise, with a REAL step by step process. Thank you very much.

I only want to add something: on my model (EU) the battery is attached to the body by two striped along the short sides of the battery. It can be hard to work on those stripes so pur extra attention on that.

Excellent guide. The biggest pain by far was removing the old battery. I didn’t have a heat gun so just used a hair dryer for the multiple rounds of heating and prying. I did end up deforming the old one quite a bit getting it out, but luckily nothing happened. Also, on my adhesive, the U-shaped cutout was *not* at the top left. Just make sure the speaker holes line up.

Excellent instructions! I read it several times while waiting for my new battery to come from ifixit. I was pretty confident in my abilities and knew the risks of damaging the screen in the process. Sure enough, after going through the whole procedure and plugging my old screen back in, half of it was blank… Pretty sure I flexed the screen too much while lifting on it with the suction cup and cracked it. The screen is a lot thinner and flexible than I was expecting. I would have preferred to give more business to ifixit but I didn’t want to be down for another whole week so I had to order a new screen from online company with free 2 day shipping… No complaints towards the author or ifixit at all. I would attempt this repair again.

I just want to mention that even the packaging for the repair parts and tools was impressive. Lots of attention to detail. Only complaint about the tools is that I would have paid a few extra bucks to include some kind of case for the tools. Thanks!

One simple method I use to remove the battery. After heating up the back of the phone, I use an old gift card and insert it through the side of the battery and since its larger and flexible your able to reach the strips of glue underneath the battery and loosen it from the battery. A lot safer than pulling and togging at the battery from the top and the potential risk of puncturing it . Just make sure to look for locations that have any circuits underneath the battery and avoid those spots. Works well for any other phones or tablets. I used it on this phone and only needed to heat it up once. Hope this helps someone.
