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 edge in turn with the iOpener or a hair dryer, 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: 3mm at the bottom and top, 5mm on the right (twist the pick to release the clip by the power button) and only 2mm on the left, where two screen cables run
• Swing the screen open to the left like a book and prop it up until its cables are unplugged. Spring contacts run all the way round the frame, so keep the pick shallow
• 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.
• Slide the logic board cover (Y000) towards the bottom to remove it, then unplug the battery, ambient light sensor and screen and lift the screen off. Remove the loudspeaker (Phillips; tape joins it to the Taptic Engine) and the Taptic Engine (standoff screw) to reach the battery
• Three stretch-release strips hold the battery, two along the bottom and one on the top, which breaks most often. Pull each tab slowly, low and flat, without pressing on the battery. Hold the battery as you pull. If a strip breaks, drip isopropyl alcohol under that edge, wait a minute, then lift the battery slowly with a plastic card. Never pry near the wireless charging coil in the middle of the frame
• 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 screen adhesive with isopropyl alcohol and fit a new screen gasket 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
