Introduzione

iPhone batteries degrade with use—over time, they lose their ability to hold a full charge. Apple's batteries are rated to hold 80% of their capacity for up to 500 charge cycles, which lasts roughly 18-24 months for most users. When your battery's chemistry is degraded, it may also cause your iPhone to run more slowly. Use this guide to replace your battery and restore your iPhone to full performance.

If your battery is swollen, take appropriate precautions.

This guide instructs you to completely detach the display and remove the lower speaker and Taptic Engine for better access to the battery's adhesive strips.

For optimal performance after completing the guide, calibrate your newly installed battery: Drain it below 10%, then charge it uninterrupted to 100%.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.

    • Opening the iPhone will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.
    • Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun, or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

    • The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone XR.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

      • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

    • Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone.

      • Don't try to completely separate the screen; a small opening along the bottom edge is all you need.

    • Insert an opening pick into the gap under the display on the lower edge of the iPhone.

    • Skip the next two steps and continue to step 8.

    • If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass.

      • If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

    Aggiungi Commento

    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

    • Slide the opening pick around the lower left corner and up the left edge of the iPhone, slicing through the adhesive holding the display in place.

      • Don't insert the opening pick too far into the iPhone, or you may cause damage to internal components.

    Aggiungi Commento

    • Re-insert your pick at the bottom edge of the iPhone, and slide it up the right side to continue separating the adhesive.

      • Don't insert the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

    Aggiungi Commento

    • The top edge of the display is secured with both glue and clips.

    • Slide the opening pick around the top corner of the display, while gently pulling or wiggling the display down in the direction of the Lightning port.

      • The clips will break if you use too much force. Work carefully and be patient.

      • Again, don't insert the pick more than a few millimeters—about the width of the display bezel—or you may damage the front panel sensor array.

    • Slide the pick to the opposite corner and cut any remaining adhesive securing the display.

    Aggiungi Commento

    • Pull on the small nub on the suction cup to remove it from the front panel.

    • If you used an iSclack and it's still affixed to the iPhone, remove it now.

    Aggiungi Commento

    • Open the iPhone by swinging the display up from the left side, like the back cover of a book.

    • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

    • During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

    • Remove three 1.2 mm Y000 screws securing the battery connector bracket.

    • Remove the bracket.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

    • During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

    • Try to keep the adhesive strips flat and unwrinkled during this procedure; twisted or wrinkled strips will stick together and break instead of pulling out cleanly.

    • Additionally, do not press down on the battery as you pull the strips. Pressing on the battery creates pressure points that can snag and break the adhesive.

    • Slowly pull one battery adhesive tab away from the battery, towards the bottom of the iPhone.

    • Pull steadily, maintaining constant tension on the strip until it slips out from between the battery and the rear case. For best results, pull the strip at as low an angle as possible, without snagging it on any of the iPhone's other components.

      • The strip will stretch to many times its original length. Continue pulling and re-grab the strip near the battery if necessary.

    • If the battery adhesive tabs break during the removal process, use your fingers or blunt tweezers to retrieve the remaining length of adhesive, and continue pulling.

    • If any of the adhesive strips break underneath the battery and cannot be retrieved, try to remove the remaining strips, and then proceed as instructed below.

    • Repeat the above steps to remove the remaining three adhesive strips.

      • Be sure to hold onto the battery as you remove the final strip, or it may fling out of the iPhone unexpectedly.

    • If you removed all of the adhesive strips successfully, skip the next step.

    • If any of the adhesive strips broke off underneath the battery and could not be retrieved, continue with the next step below.

    Aggiungi Commento

    • If any of the adhesive strips broke off and the battery remains stuck to the rear case, prepare an iOpener or use a hair dryer to heat the rear case directly behind the battery. This will help soften the adhesive.

      • Heat the iPhone until the rear case is slightly too hot to comfortably touch. Don't overheat the iPhone, or you may accidentally ignite the battery.

    • Flip the iPhone back over and thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

      • Wrap the ends of the string around a cloth (or wear gloves) to protect your fingers.

    • Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. This can take some time since the adhesive is slow to deform, but with patience it will come free. Do not deform or damage the battery.

    • If you choose to use pry tools to lift the battery out of the iPhone, use extreme caution or you may damage the ribbon cables or the wireless charging coil directly underneath the battery.

    Aggiungi Commento

    • Remove the battery from the iPhone.

    • Reinstall the Taptic Engine and speaker before installing a new battery. This helps keep the battery aligned correctly during installation.

    • When installing the battery, refer to this guide to replace your battery's adhesive strips.

    • Perform a force restart after reassembly. This can prevent several issues and simplify troubleshooting.
