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
- Warm each edge of the glass back with the iOpener in short bursts, as too much heat can damage the battery and screen. Lift the bottom edge with a suction cup and work an opening pick around, only 4 to 5mm deep by the cameras and 3 to 4mm by the power button, where the button cable runs
- Track your screws on a magnetic mat or tape them to a drawing of your phone, so each one goes back in the right place
- Unplug the battery as soon as you can reach it, before you remove anything else. Keep metal tools away from the battery, and never bend, crush or puncture it.
- Remove the NFC antenna and charging coil assembly, unplug the battery, then remove the loudspeaker. Fold the display, main and interconnect cables out of the way
- The battery glue is very strong. Drip a few drops of isopropyl alcohol under each side, wait two to three minutes and lift with a suction cup and a plastic card; warming the screen side helps. Use alcohol sparingly, as gaps in the frame let it run onto the screen
- Clean off any old adhesive and fit the new battery adhesive from the box. Press the battery connector down until it clicks, then check the phone powers on and charges before you close it up
- Clean off the old back cover adhesive and fit the new adhesive before you close it up
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.
