Motorola Moto Z Play Battery Replacement

Introduction

Prerequisite only for removing the battery.

Use a spudger to disconnect the battery by prying its connector straight up from the motherboard.

The battery is strongly glued into place.
Peel up the black pull tab at the top edge of the battery, and slowly pull it away from the battery at about a 45-degree angle to release the command strips (a.k.a. stretch-release adhesive) underneath.
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.

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.

Continue pulling up the battery until all the adhesive releases from the rear case.

Remove the battery.
Do not reuse the battery after it has been removed. The stress of removal can cause hidden damage to the battery cell, creating a potential safety hazard. Replace it with a new battery.

Before installing your new battery, peel up all the old adhesive and remove it from the phone.
For best results, clean the area underneath the battery with isopropyl alcohol and a lint-free cloth or coffee filter. This helps prep the surface so the new battery will adhere more strongly.

Place stretch-release adhesive strips or several strips of thin double-sided adhesive tape, either from a pre-cut adhesive card or from a roll of Tesa 61395, into the battery well, and press them firmly into place.

Peel off the remaining film liners to expose the adhesive before pressing your new battery into place.
Carefully position the battery and press it firmly and evenly into the phone.
Connect the battery to the motherboard, and install the lower cover, including its six T3 Torx screws.
