  1. Huawei Mate 20 Pro Battery Replacement, Rear Glass: passo 1, immagine 1 di 1
    • Before you begin, switch off your phone.

    • Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

    • Secure a suction handle to the bottom of the back cover, as close to the edge as possible.

    • If the phone's rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the back cover with the suction handle to create a small gap between the cover and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Slide the opening pick to the bottom right corner.

    • Insert a fourth opening pick under the top left corner of the back cover.

    • Slide the opening pick along the top edge of the phone to cut the adhesive.

    • Leave the opening pick in the top right corner to prevent the adhesive from resealing.

    • Lift and remove the back cover.

    • Before installing fresh adhesive and reassembling, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • 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.

    • Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply pressure for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

    Turns out that you have to remove the 4 orange screws of step 14.

    Not sure why there is a IF statement on this step.

    • Peel the orange adhesive strip labeled with a 3 off the battery.

    • Pull up the orange adhesive strip to lift the battery out of its recess.

    • Although these new adhesive tabs are supposed to make the battery removal easier, these may require some force. In case you're having trouble removing the battery, you can apply a heated iOpener to the center of the display, to loosen the adhesive underneath.

    • Peel the battery's adhesive sticker off the midframe.

    • This step is mandatory if you are replacing the screen. However it is highly recommended to use a fresh adhesive sticker as well, when installing a new battery.

    • Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

Conclusione

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

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

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

I have tried this with two new batteries now. I believe the device was water damaged by plugging the charger in while there was moisture in the port. The existing battery works but doesn't fast charge and gets very hot when charging, the battery also drains extremely quickly. Everytime insert a new battery the phone just get stuck in a boot loop, bringing up the Huawei powered by android screen before restarting, I have also replaced the charging port in hopes that may of been damaged and was causing the issue but this didn't work either. Any suggestion?

Excellent Step by step guide thank you

Mate 20 battery has a serial number and is locked to the device. Replace it and get bootlooping confirmed on more than 5 devices so far. Don't understand why this isn't more common knowledge. I've had to do battery pcb swaps for a year now.

Battery replacement also results in Bootloop here - factory reset not helping. Safe mode also not working.

I solved it by reusing the board at the base of the battery body

Sorry what do you mean by “reusing the board at the base of the battery body”?

Ralph Hsiao - Replica

Hi, I had the same issue that the phone did not accept the new battery. Luckily I found a workaround in a German newsgroup: 1) Boot up the device using the original Battery 2) connect an USB charger to the mobile 3) Disconnect the original batery and connect the new one ( you have to be quite fast, if the phone shuts down during the change you have to go back to step 1) 4) charge the phone for about 10 minutes and check if the batteryindicator moves up. 5) restart the phone and double check that the new battery is accepted. I’ve tested this method and it worked for me.

You saved my life, I saw it in the German website but it was not that easy explained

Please show us or explain a bit better how to do this?? I tried it but the phone dies immediately if you remove the battery plug

Philip Opperman -

Oh my gosh! After I tried out every suggestion I found on the internet, this eventually worked for me too! But I put a spin on it. To reduce energy consumption and keep it alive during the switch, I unplugged the screen! Beforehand, my phone died the moment I took off the battery cable. But having the screen not attached, it worked. So happy. By the way, the screen is the yellow/reddish cable that comes from underneath the battery and attaches below the lower-left camera. Having tried out the other methods suggested online, I must say that I also left my phone charging for some hours while it continuously rebooted, and I did a factory reset beforehand. But I don't think that was necessary

How did you do it the phone dies

Philip Opperman - Replica

Could you maybe post a link of the original website showing how to do this?

iamasadboy - Replica

Worked without issues! I was worried after reading the comments about battery bootlooping but no issues so far

phillip4x - Replica

I changed the battery without any problems but the phone gets stuck in bootlooping as I feared... When I let the phone bootlooping while being charged, it eventually starts but it can take a while… And then if I shut down the phone, or let the battery discharged totally, I have to do the whole thing again. Is there a way with a booted phone to change the battery ID so that the phone thinks it’s the old battery inside to prevent bootlooping? Also, can someone elaborate the hardware fix “I solved it by reusing the board at the base of the battery body” ?

Thank you for your help

Yeah I tried and just gave up, old battery still works fine with about 2/3 capacity so I popped it back in. I highly suspect that with the new HarmonyOS the trick they posted about in 2021 is patched. This is a known issue, I guess it's time to change brands for the next phone oh well.

What I tried was following all the steps outlined by the other person, while it seems to work at first the phone refuses to boot after the flashlight is plugged back in and the metal cover plate is installed on top of the motherboard.

Daniel Qi -

More complicated instructions in Chinese, really feel like ifixit needs to put a warning at the top of this tutorial...
