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 plastic back cover with the iOpener in short bursts, as heat can damage the battery, screen and back cover. Lift it with a suction cup and work an opening pick around no more than 5mm deep, and only 3mm along the right edge where a cable runs. Go slowly at the camera, where most of the glue is
- 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 motherboard bracket (the wireless charging coil stays attached to it) and unplug the battery underneath, then remove the loudspeaker. Unplug the cables that cross the battery and move them aside
- The battery is glued in. Drip a few drops of isopropyl alcohol under its edges, wait a couple of minutes, then lift it slowly with a suction cup and a plastic card. Too much alcohol can reach the board or damage 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.
