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 back glass edges with the iOpener in short bursts to protect the battery. Lift the bottom edge of the back glass with a suction cup and work an opening pick around, no more than 3mm deep. Keep it out of the right edge, where a cable runs, and go gently at the top left by the cameras
- Open the back glass from the left side like the back cover of a book, and support it so you don't strain the short charging coil cable
- 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 battery connector cover (Y000) and unplug the battery, then the charging coil connector cover (Y000). Unplug the coil cable and lift the back glass off. The battery is now in front of you, and the screen stays on
- Two stretch-release strips hold the battery, both reached from the top edge. Pull each tab slowly towards the top 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 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
Caution
If the new battery or the battery in your device is swollen or damaged during repair, take the proper precautions
Note
You cannot dispose of old batteries in your general waste. Find recycling e-waste centres online or take to your local refuse station.
