Here are some helpful tips to assist you in completing a safe repair on your device. If you are unsure of something or have any questions, please feel free to contact us either by phone (0508 IGADGET) or by email

• 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, as too much heat can damage the battery. Lift the bottom edge with a suction cup and work an opening pick around. Maximum pick depth: 5mm at the bottom and left, 7mm on the right (stop before the volume buttons), 4mm at the top right corner, 3mm along the top, where two clips let go. Never put a pick by the volume up button, where the back glass cable runs
• The back glass swings open to the right. Rest it on something the same height as the phone so its cable isn't strained
• 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 lower connector cover (Y000 screws; slide it towards the top) and unplug the battery press connector. Remove the middle cover (Y000 screw; push it towards the bottom), unplug the wireless charging and NFC cable and lift the back glass off. The screen stays on. Free the lightly stuck battery cable with a pick without creasing it
• Two stretch-release strips hold the battery, with pull tabs at the top. The adhesive wraps over the top edge, so peel the tabs back and slice through the wrap with a pick. Pull each strip out slowly, low and flat; winding it around your tweezers. Hold the battery as you pull. If a strip breaks, drip isopropyl alcohol under the right and top edges, wait a minute, then lift the battery slowly from the left edge with a plastic card, without bending it
• Clean off any old adhesive and fit the new adhesive strips from the box. Press the battery connector down until it clicks, then check the phone powers on and charges before you seal it up
• Clean off the old adhesive with isopropyl alcohol and fit a new back glass adhesive before you close it up
• Once the phone is back together, update to the latest iOS, connect to Wi-Fi and charge above 20%. Go to Settings, General, About, Parts & Service History, tap Restart & Finish Repair and follow the steps. Until you do, Finish Repair shows next to Battery
• 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
