Introduction

Use this guide to replace a dead or low battery.

If your battery is swollen, take appropriate precautions.

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%.

Step 1

Power your phone off before you begin.
If possible, drain the battery before disassembly. When the battery is charged, there's increased risk of a dangerous thermal event if the battery is overheated or damaged during repairs.
If the rear glass is cracked, completely cover it with packing tape to contain the glass shards and avoid injury.
Prepare an iOpener and heat the back of the phone along its bottom edge for about two minutes, or until it's slightly too hot to touch. This will help soften the adhesive securing the rear glass.
You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

VERY IMPORTANT!

If you don’t buy the original replacement battery, make sure that its size is not wider than 43mm.

The replacement battery that I had was wider and I found it out only at the last step, when I realized that it didn’t fit in… :-(

Step 2

Apply a suction cup to the bottom edge of the rear glass.
Pull up on the suction cup with firm, constant pressure to create a slight gap between the rear glass and the case.
If the glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.
This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool.
If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools quickly, so you may need to heat it repeatedly.
Insert an opening pick into the gap you created under the rear glass.

Step 3

Slide the pick all along the bottom edge of the phone to slice through the adhesive securing the rear glass.
Slow down and slice very gently as you get to the corners. The curved part of the glass along the left and right edges can crack very easily if the pick pushes up against the curved glass.
After being cut, the adhesive will sometimes stick back together as it cools. To prevent this you can leave the pick in this edge after cutting, and continue the next steps with a new pick. You can repeat this with each edge, leaving a pick and continuing with a new one.

Step 4

Heat the right edge of the back of the phone to soften the adhesive underneath.

Step 5

Slide the pick along the right edge of the rear glass to separate the adhesive underneath.

Step 6

Heat the top edge of the back of the phone to soften the rear glass adhesive.

Step 7

Slide the pick all along the top edge of the phone to slice through the adhesive securing the rear glass.
Slow down and slice very gently as you get to the corners. The curved part of the glass along the left and right edges can crack very easily if the pick pushes up against the curved glass.

Step 8

Heat the left edge of the back of the phone to soften the adhesive underneath.

Step 9

Slide a pick along the left edge of the phone to slice through the rear glass adhesive.

Step 10

If the glass remains stuck, re-heat and slice the adhesive repeatedly as needed.
Lift the rear glass carefully, making sure it's fully separated from any adhesive.
Remove the rear glass.
During reassembly, pause here to replace the adhesive on the rear glass using a precut adhesive card or high-strength double-sided adhesive tape, such as Tesa 61395.

Step 11

Use a Phillips driver to remove ten screws securing the upper plastic cover.
Seven 3.2 mm-long screws
Three 2.7 mm-long screws

Step 12

Insert the flat end of a spudger into the notch on the right edge of the upper plastic cover.
Pry up with the spudger to lift the edge of the upper cover and release the clips holding the cover down.
Remove the upper plastic cover.
When reinstalling the plastic cover, make sure the tab on the black sticker gets properly seated over the two small posts on the inside of the cover.

The tab, actually, remained glued to the plastic cover, but it worked anyway. We just had to keep them together in step 14

Unfortunately my selfie camera would not fit in the new display. They must have changed the design somewhere along the line.

I would advice to try the fit of upper cover on the new screen before proceeding further.

My uppercover would not fit on the new display.

Since the return postage of the screen was more than the phone was worth I carefully sanded the upper cover with a diamond nail file until it fitted in the new display. I had to remove about 0.4mm

Actually the new screen was 160mm long , the original screen was 162mm.

The phone is working now but it required a lot of care full diamond filing of the case back. And the sim tray sticks out 2mm.

Step 13

Use the flat end of a spudger to pry up the battery connector and disconnect it.
During reassembly, this is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

Step 14

Very carefully peel up all the black stickers covering the battery.
The largest sticker, which covers the battery and the motherboard, does not need to be removed from the motherboard for battery removal—just peel it off of the battery.
If possible, keep the tape intact so it can be reused during reassembly.

The largest adhesive film is almost impossible to be kept intact because the outer film de-laminates from the adhesive layer (it is even visible in the second picture here).

The third sticker was not there, in my phone.

Step 15

Prepare an iOpener and apply it directly to the battery for at least two minutes. Reheat and reapply the iOpener as needed.
Be careful not to overheat the battery with the iOpener. If you notice the battery swelling at all, immediately remove any heat and let the battery cool down.
Alternatively, apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

It would be good, here, to specify that there are 3 strips of adhesive (see second picture of step 17).

I would recommend to only insert opening picks or spudger where the adhesive strips are (in the centre and , in order to avoid scratching the two black strips, as I see also happened here)

Step 16

Use an opening pick to steadily pry the battery up, starting from the right edge of the battery.
You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the pick started under the battery.
Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

Step 17

Lift the battery out of the phone case.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
Before installing your new battery, peel up all the old adhesive and remove it from the phone.
For best results, clean the area underneath the battery with isopropyl alcohol and a lint-free cloth or coffee filter. This helps prep the surface so the new battery can adhere more strongly. Replace old adhesive with stretch release adhesive strips, double-sided tape, or pre-cut adhesive strips.
If you're also replacing the screen assembly, which includes the midframe, the new midframe may have battery adhesive pre-installed. In that case, don't apply any more adhesive—just peel the backing off the preinstalled adhesive and install the battery.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

For optimal performance, after completing this guide, calibrate your newly installed battery.

Take your e-waste to an R2 or e-Stewards certified recycler.
