iPhone SE 2020 Battery Replacement

Go to step 1

Use this guide to revive your iPhone SE 2020’s battery life and performance with a new battery. If your battery is swollen, take appropriate precautions.

This guide instructs you to completely detach the display assembly; this is intended to prevent accidental damage to the display cables. If you feel comfortable removing the battery without putting undue strain on the display cables, you can skip the steps for detaching the display. Additionally, while it’s possible to remove the adhesive strips securing the battery as soon as you open the phone, this guide recommends first removing the Taptic Engine. Doing so reduces the risk of breaking the lower adhesive strips accidentally, either by snagging them on the Taptic Engine, or by pulling the strips at too sharp of an angle.

For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your iPhone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

  1. iPhone SE 2020 Battery Replacement, Remove the pentalobe screws: step 1, image 1 of 1

    • 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 3.5 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.

    • If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.

    • Measure 3 mm from the tip and mark the opening pick with a permanent marker.

    • You can also mark the other corners of the pick with different measurements.

    • Alternatively, tape a coin to a pick 3 mm from the tip.

  3. iPhone SE 2020 Battery Replacement, Heat the display: step 6, image 1 of 1

    • The next three steps show how to separate the screen using a suction cup.

    • 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 phone for about 90 seconds in order to soften up the adhesive underneath.

  4. iPhone SE 2020 Battery Replacement, Separate the display: step 7, image 1 of 2 iPhone SE 2020 Battery Replacement, Separate the display: step 7, image 2 of 2

    • Apply a suction cup to the lower half of the front panel, 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.

  5. iPhone SE 2020 Battery Replacement: step 8, image 1 of 3 iPhone SE 2020 Battery Replacement: step 8, image 2 of 3 iPhone SE 2020 Battery Replacement: step 8, image 3 of 3

    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the screen 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.

  31. iPhone SE 2020 Battery Replacement, Remove the battery adhesive: step 33, image 1 of 1

    • The iPhone's battery is secured by four pieces of stretch-release adhesive—two at the top, and two at the bottom.

    • Each piece of adhesive has a black pull-tab at the end, which is lightly adhered to the front surface of the battery.

  32. iPhone SE 2020 Battery Replacement: step 34, image 1 of 3 iPhone SE 2020 Battery Replacement: step 34, image 2 of 3 iPhone SE 2020 Battery Replacement: step 34, image 3 of 3

    • Peel back the first battery adhesive tab from the bottom right edge of the battery.

    • If possible, use your fingernails or blunt tweezers. Be careful not to poke the battery with any sharp tools.

  33. iPhone SE 2020 Battery Replacement: step 35, image 1 of 3 iPhone SE 2020 Battery Replacement: step 35, image 2 of 3 iPhone SE 2020 Battery Replacement: step 35, image 3 of 3

    • 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.

  34. iPhone SE 2020 Battery Replacement: step 36, image 1 of 3 iPhone SE 2020 Battery Replacement: step 36, image 2 of 3 iPhone SE 2020 Battery Replacement: step 36, image 3 of 3

    • 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.

  35. iPhone SE 2020 Battery Replacement: step 37, image 1 of 2 iPhone SE 2020 Battery Replacement: step 37, image 2 of 2

    • 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.

    • 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 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.

    • 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. 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.

    • Alternatively, thread a strong piece of string (such as dental floss or a length of thin guitar string) underneath the battery.

    • Pull the string from side to side in a sawing motion all along the length of the battery to separate the adhesive. Do not deform or damage the battery.

    • To protect your fingers, wear gloves or wrap the string ends around a tool (such as the two screwdriver handles shown in the image).

  36. iPhone SE 2020 Battery Replacement, Remove the battery: step 38, image 1 of 1

    • Remove the battery from the iPhone.

    • If your replacement battery came in a plastic sleeve, slide off and remove the sleeve before installation.

    • 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.

    • 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.

    • 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.
