Introduction
Use this guide to bring life back to your iPhone 5s with a new battery.
Before you begin, drain your iPhone's battery below 25% charge. This will minimize the risk of a dangerous thermal runaway in the event that you accidentally deform or puncture the battery.
This guide instructs you to remove the front panel assembly; this is intended to prevent damage to the display cables. If you feel comfortable supporting the display carefully while peeling the battery out of the iPhone, skip the display removal and go directly to the battery removal steps.
For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.
What you need
Video Overview
-
-
If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.
-
Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered.
-
-
-
Close the handle on the iSclack, opening the suction-cup jaws.
-
Place the bottom of your iPhone in between the suction cups, against the plastic depth gauge.
-
The top suction cup should rest just above the home button.
-
Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.
-
-
-
Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case.
-
The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the home button cable.
-
Skip the next three steps and continue on Step 9.
-
-
-
If you don't have an iSclack, use a single suction cup to lift the front panel:
-
Press a suction cup onto the screen, just above the home button.
-
-
-
While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the home button end of the front panel from the rear case.
-
With a plastic opening tool, gently pry the edges of the rear case down, away from the front panel assembly, while you pull up with the suction cup.
-
-
-
Open the phone just enough to reveal the metal bracket covering the home button cable.
-
Only the phone's original home button assembly will be capable of using the Touch ID functionality. If you rip the cable, installing a new home button will only restore ordinary home button functions, not the Touch ID features.
-
Use the tip of a spudger to push the bracket free and remove it with tweezers.
-
-
-
Once the connector has been released, pull the home button end of the assembly away from the rear case, using the top of the phone as a hinge.
-
Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.
-
Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.
-
-
-
Slowly pull one of the battery adhesive strips away from the battery, toward the bottom of the iPhone.
-
Pull steadily, maintaining constant tension on the strip as it slips out from between the battery and the rear case. For best results, pull the strip at a 60º angle or less.
-
Guide the strip carefully around the corner and up the side of the battery. Be careful not to snag it on any of the other internal iPhone components.
-
-
-
Flip the iPhone back over and insert a plastic card between the case side of the battery and the rear case.
-
Press the card in farther to break up the adhesive behind the battery.
-
Thread the floss or string behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.
-
To reassemble your device, follow these instructions in reverse order. For optimal performance, calibrate your newly installed battery: Drain battery below 10%, then charge uninterrupted to 100%.
