    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.6 mm Pentalobe P2 screws next to the dock connector.

    • Be sure the driver is well-seated when removing Pentalobe screws—they are easy to strip.

    • Use a plastic opening tool to gently pry up the battery connector from its socket on the logic board.

    • Place the tip of the tool between the loudspeaker enclosure and the metal cover of the connector, and lift the bottom edge of the connector first.

    • The battery connector comes off vertically from the logic board. Do not apply force sideways.

    • Be careful not to pry at the battery connector socket itself, or it may detach from the logic board. There are four very small solder points awaiting this mistake!

    • During reassembly, be sure to carefully position the pressure contact back in place. It should rest on top of the Philips screw post shown, and the gold contact should point towards the battery connector.

    • Be sure to clean the pressure contact with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.

    • Insert the edge of a plastic opening tool between the battery and the outer case near the bottom of the iPhone.

    • Run the plastic opening tool along the right edge of the battery and pry up at several points to completely separate it from the adhesive securing it to the outer case.

    • If the adhesive is too strong, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery.

    • Wait about one minute for the alcohol solution to weaken the adhesive.

    • Use the flat end of a plastic opening tool to gently lift the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • Use the exposed clear plastic pull tab to peel the battery off the adhesive securing it to the iPhone.

    • Be careful not to pull the plastic pull tab too hard as it can be ripped off very easily.

    • Remove the battery.

    • If your replacement battery came in a plastic sleeve, remove it before installation by pulling it away from the ribbon cable.

    • If your replacement battery came with an uncreased cable, carefully crease the cable into the proper shape before installing the battery into the phone.

    • While installing the replacement battery, temporarily connect the battery connector to the phone to ensure proper alignment. Once the battery is glued in place, disconnect the battery connector.

    • Perform a hard reset after reassembly. This can prevent several issues and simplify troubleshooting.

    • Carefully lift the logic board from the end closest to the speaker enclosure and slide it away from the top edge of the iPhone.

    • Remove the logic board.

    • Before reassembly, be sure to clean all metal-to-metal contact points on the logic board (not the mating halves of connectors) with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause grounding issues.

    • There is a small rubber bumper that sits on the top edge of the logic board where the digitizer and screen cables come through the case. It protects the cables as they bend over the top of the logic board. This can either get stuck to the cables or fall off the logic board when it comes out. Look back over step 22 for more details.

This guide is marked as difficult. You are doing it at your own risk. Backup your device and make sure you have everything you need before attempting it. Otherwise, good luck and hope you succeed.

The biggest and hardest part of all this is keeping up with all the screws and brackets, as well as removing certain brackets.
