Nokia Lumia 735 Battery Replacement

Stick your opening pick between the plastic casing and the screen

Move your pick up toward the top corner of the phone

Rotate the pick so it is parallel with the back of the phone

Move the pick in between the back of the phone and the plastic cover to the top left corner

Use the gap made by the pick between the back plastic and the phone to pry apart the two parts

The back should now be removed exposing the battery, SIM card, and SD card on the back of the phone

Insert the pick into the opening near the top of the battery

Use the pick to lift up the battery until you can remove it from its resting place

The battery should now be removed from the phone

Insert the new battery bottom first, lining up the connectors on the battery with the connectors on the phone

Slide the battery in and push it down so it stays in its place

Line up the back with the back of the phone

Push down on the back until you hear it snap into place

Congratulations! You just replaced the battery on your phone, you may turn it back on and begin using it normally.
