Separate the small, clear tabs above and below the blue part of the pull tab from the rest of the pull tab.

Bend these small tabs away from the battery to make sure they stay clear of the battery.

If these tabs aren't separated, you won't be able to lift the battery in the next step. You can tape these tabs to the side of the phone or the screen to keep them out of the way.

Your device may have two tabs on the bottom edge of the battery. These are designed to tear away during the next step, but if you have trouble removing the battery, you can carefully peel these tabs up as well.
