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 Lightning port. Warm the edges 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, and only 2mm along the left edge where the display cables run. Never put a pick between the plastic bezel and the display panel
• Open the screen from the right-hand side like a book and support it until its cables are unplugged
• Track your screws on a magnetic mat or tape them to a drawing of your phone. The battery connector cover alone has eight Y000 screws in three 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 battery connector cover, unplug the two display cables and lift the screen off. Remove the loudspeaker (Phillips) and the Taptic Engine (Phillips and a standoff screw) to reach the battery
• Four stretch-release strips hold the battery, two on the bottom edge and two on the top. Pull each tab slowly towards the bottom of the phone, low and flat; winding it around your tweezers. 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
• 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
