• Always track your screws to avoid putting back in the wrong place and damaging your device. You can draw a picture of your phone and tape the screws to the right places or use a screw mat
• Always power down your device prior to working on it
• Make sure you always unplug the battery before attemping any component removal
• Before removing your battery, discharge the battery to below 25%. A charged lithium-ion battery can catch fire or explode if punctured or damaged
• If your newly installed battery is draining fast or shutting off randomly, try the following steps to resolve it
• Open up the device and unplug the battery
• Check the phone and battery connector for rogue bits of foam or debris and remove
• Plug the battery connector back into the phone making sure it is seated correctly (should hear an audible click)
• Inspect the flex cable to make sure there is no strain on it when the battery is plugged in. If there is any strain you may need to remove the battery and reposition (higher, lower, closer, further away from connector) so that the cable sits without stretch.
• Put phone back together and turn on
