How To Get An Iphone Replacement Battery

• 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 3.4 mm pentalobe screws on the bottom edge of the iPhone.

• Opening the iPhone's display 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.

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

• Use a hairdryer 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.

• Attach a suction cup to the lower half of the display assembly, just above the home button.

• Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front 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.

• Pull up on the suction cup to create a small gap between the display assembly and the rear case.

• Insert the flat end of a spudger into the gap.

• The watertight adhesive holding the display in place is very strong, and creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, rock the screen up and down to weaken the adhesive until you can fit a spudger inside.

• Slide the spudger to the left along the lower edge of the iPhone.

• Twist the spudger to widen the gap between the display and rear case.

• Slide the spudger up the left side of the iPhone, starting at the lower edge and moving towards the volume control buttons and silent switch.

• Do not pry along the top edge of the phone, you risk damaging the plastic clips securing the display.

• Insert the flat edge of a spudger into the bottom right corner of the device.

• Twist the spudger to widen the gap between the display assembly and the rear case.

• Slide the flat end of the spudger up the right side of the phone to break up the adhesive holding the display in place.

• Do not insert the spudger further than the adhesive to avoid damaging delicate ribbon cables along the right edge.

• Pull up on the suction cup to lift up the display and open the iPhone.

• Do not raise the display more than 10º as there are ribbon cables along the right edge of the device connecting the display to the logic board.

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

• Slide an opening pick along the top edge of the iPhone, between the rear case and front panel, to break up the remaining adhesive holding the screen in place.

• Be careful not to damage the plastic clips on the top edge of the phone.

• Pull the display assembly slightly away from the top edge of the phone to disengage the clips holding it to the rear case.

• 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.

• Remove four tri-point Y000 screws securing the lower connector bracket, of the following lengths:

• Three 1.2 mm screws

• One 2.4 mm screw

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

• Remove the lower connector bracket.

• Use the point of a spudger to lift the battery connector out of its socket on the logic board.

• Bend the connector cable up slightly to prevent it from making contact with the socket and providing power to the phone.

• Make sure the battery is disconnected before you disconnect or reconnect the cables in this step.

• Use a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board.

• To reconnect these cables, press down on one end until it clicks into place, then repeat on the opposite end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

• If you have a blank screen, white lines on the display, or partial or complete lack of touch response after reassembling your phone, try disconnecting and carefully reconnecting both of these cables and make sure they are fully seated.

• Remove the two 1.3 mm Phillips #000 screws securing the bracket over the front panel sensor assembly connector.

• Some phones could be Y000. Apple started using Y000 for these at some point in the middle of the product's lifecycle.

• Disconnect the front panel sensor assembly connector from its socket on the logic board.

• This press connector should also be reconnected one end at a time to minimize the risk of bending.

• Remove the display assembly.

• During reassembly, pause here if you wish to replace the adhesive around the edges of the display.

• Remove the two 1.9 mm Phillips screws securing the barometric vent to the rear case.

• Remove the vent.

• Use the flat end of a spudger to disconnect the Taptic Engine connector from its socket on the logic board.

• Remove the three 1.6 mm Phillips screws securing the Taptic Engine to the rear case.

• Remove the Taptic Engine.

• Use a pair of tweezers with blunt tips to peel back one of the adhesive strips on the lower edge of the battery.

• Use a pair of tweezers with blunt tips to peel back the other adhesive strip on the lower edge of the battery.

• If this is your first time removing an iPhone battery adhesive strip, refer to the video in the following step before beginning.

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

• Slowly pull one battery adhesive tab away from the battery, toward 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 a 60º angle or less.

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

• Repeat the previous step for the second strip.

• Hold down the battery as you remove the second strip, or the strip may fling the battery when it separates from the case.

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

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

• If any of the adhesive strips broke off and the battery remains stuck to the rear case, remove it by adding a few drops of isopropyl alcohol (90% or greater) underneath the battery near the stuck strip(s).

• After about a minute, gently lift the battery.

• Do not insert your spudger in the area between the volume down (-) button and the top edge of the battery, or you may damage the volume control cable lying underneath.

• Do not pry against the logic board or you may damage the phone.

• Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

• If 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. It should be slightly too warm to touch comfortably.

• Overheating the iPhone may ignite the battery.

• A piece of dental floss may be used to separate the battery from the rear case. A stronger alternative to dental floss is an unwound guitar string, such as a 0.009 E string from a 12-string set. Thread the floss or string behind the upper battery corners, bring the ends together, wrap them around a folded cloth, and pull evenly.

• Remove the battery from the rear case.

• If your replacement battery came in a plastic sleeve, remove the sleeve before installation by pulling it away from the ribbon cable.

• If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

• Before you adhere the replacement battery, temporarily reconnect the battery connector to the logic board socket. This ensures that the battery is properly aligned in its recess.

• Adhere the battery, disconnect it, and continue reassembling your device.

• If your new battery doesn't have adhesive preinstalled, refer to this guide to replace the adhesive strips.

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