Apple batteries are able to maintain 80% capacity during 500 charge cycles, which for most users take approximately 18-24 months.  Battery wear means charging more often, but it can also slow down your iPhone, so use this guide to restore full performance to your device.

This manual also includes instructions for completely disconnecting the display, removing the bottom speaker, and the taptic engine, for better access to the battery sealing strips.

After completing the repair, calibrate your new battery for optimal performance.  Charge the battery to 100% and let it charge for at least another 2 hours.  Then use iPhone until it's fully discharged, then charge to 100% without interruption.

Step 1
Removing the pentalobe screws

Removing the pentalobe screws

Before starting, it is necessary to discharge the iPhone below 25% because a charged Li-ion battery can ignite or explode if accidentally cut.

  • Turn off iPhone
  • Unscrew the two 6.75 mm long pentalob screws on the bottom edge of the iPhone using a Pentalobe screwdriver (Ph0001.2)

Opening iPhone will break its waterproof seal, so have a replacement seal ready before beginning this step.  Without a new seal, your iPhone will not be waterproof.

Step 2
Opening 1

Warming the bottom edge of iPhone helps soften the screen protector and make it easier to open.

  • Using a hair dryer or heat gun, heat the bottom edge of iPhone for about 3 minutes to bring the temperature to about 80 ° C.
  • Do not put iPhone in the microwave !!!

Step 3

  • Place the suction cups near the bottom edge of iPhone, one at the front and the other at the back, and gently push it into place.
  • Hold your iPhone securely and use gentle suction cups to separate the screen from the back of the phone.
  • After separating the display approx. 3 mm from the back, insert the Fixservis card into the gap.

The glue that holds the display in place is very strong, so creating this initial gap requires considerable force.  If you have difficulty, reheat the bottom edge and gently slide the screen up and down repeatedly to weaken the glue until you create a gap to insert the Fixservis card.

Step 4

  • After successfully releasing the adhesive from the edges, remove the suction cups.
  • Open iPhone by turning the display to the left like a book.
  • We recommend that you support the display so that you do not tear off the flat flex cable that holds the display from the system board.

For now, don't try to completely detach the display, as a few fragile flat cables still connect it to the iPhone's motherboard.
