Sony Ericsson Xperia Play Battery Replacement

Turn the phone around so the screen is facing a flat surface.

To remove the cover, use plastic removal tool on the seam of the case.

Once enough force is applied, you should hear a “click” sound which indicates that cover is loose.

After the “click” noise, lift the cover with your finger.

Proceed with removing the battery by lifting the battery with a small plastic pry tool.

Remove the battery from the device.

Once the old battery is removed, slide the new battery, with the positive/negative indicator facing up, in so that the contacts of the battery make contact with the contacts of the phone.

Lightly press the battery into the phone so that it is secure.

To put the cover back on, apply force until a "click" sound is heard.
