Now its time to bring the phone back to the heat mat. If you have the iOpener you can lay it on the batteries. It does not need to be heated on the screen side.

Be sure to use the isopropyl alcohol on both batteries while it is on the heater.

Use your iFixit plastic prying card to find a space it fits under the battery and pry up after a few minutes in the Heat/ISO bath.

While pulling out the battery be mindful not to catch on any cables and that the adhesive comes off a lot easier while it is still wet with the isopropyl alcohol.
