• Drain the battery below 25% and power the phone off before you start. A charged lithium-ion battery can catch fire if it's punctured or damaged
• Remove the pentalobe screws by the USB-C port. Warm each back glass edge in turn with the iOpener in short bursts to protect the battery. Lift the bottom edge with a suction cup and work an opening pick around no more than 3mm deep on every edge. Keep picks away from the volume up button, where the back glass cable runs, and never slide past the volume buttons
• The back glass swings open to the right and stays connected by its cable until the cover is off, so prop it up
• Track your screws on a magnetic mat or tape them to a drawing of your phone. They're different lengths, and a long screw in a short hole can damage the logic board
• Always unplug the battery before you remove any other parts. Keep metal tools away from the battery, and never bend, crush or puncture it.
• Remove the middle connector cover (Y000; slide it towards the left edge), then unplug the battery press connector and the wireless charging coil connector and lift the back glass off. The screen stays on
• There are no pull strips: the battery adhesive lets go under low voltage. Peel up the silver tab at the battery's bottom edge. Clip a red lead to the tab and a black lead to the grounding screw on the loudspeaker, lower right. Power it for about 90 seconds with a VoltClip on a powered USB-C cable (Apple uses 9V for 1 minute 30 seconds). Keep the clips from touching each other or any other metal. Lift the battery with a suction cup; if it won't move, power it another minute rather than prying
• Clean the frame bare with isopropyl alcohol (the old adhesive is clear, so wipe 5 to 10 times) and let it dry. Stick the battery adhesive to the battery first, fold the silver tab to the front so a clip can reach it next time, then lower the battery straight in against the logic board and loudspeaker, as it can't move once it touches. Press firmly for about 10 seconds
• Press the battery connector down until it clicks and check the phone powers on and charges. Clean off the old adhesive with isopropyl alcohol and fit a new back glass adhesive before you close it up
• If the new battery drains fast or shuts off, reseat the battery connector, check it for foam or debris and make sure the flex isn't strained, then do a force restart
