    • Switch off your phone.

    • Use an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Huawei P20 Pro is of moderate strength, however a hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

    Ich hatte keinen iOpener. Daher hab ich das P20 Pro für ein paar Minuten auf eine Wärmflasche gelegt. Die Klebeschicht konnte relativ schnell gelöst werden.

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

    • Press a suction cup onto the rear glass close to the bottom edge of the phone.

    • Lift the bottom edge with the suction cup, opening a slight gap between the rear glass and the frame.

    • Insert an opening pick in the gap and slide it to the bottom right corner. Leave it there to prevent the adhesive from resealing.

    if the back cover is not broken, i’d suggest NOT to use an opening pick as if the phone was not heated enough, you may crack the glass on the edges. better use the iPlastix, it is thinner and less stressful for the glass.

    It is better to put a peak on the side because the side opens first than the bottom of the phone.

    I have to agree that is is much easier to start opening from the side. Do read the rest of the guide though, to make sure you won’t hit something when opening it from the side.

    • In case you have trouble to pry up the battery the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for about two minutes to help weaken the adhesive.

    • Try your best not to deform the battery during the following removal 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.

    • Insert the flat end of a spudger at the top left corner of the battery and start to pry it up.

    • Work your way down the left side of the battery and loosen the adhesive with the spudger.

    • Remove the battery.

    • Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.

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

    • 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 for 5-10 seconds.

Conclusão

To reassemble your device, follow these instructions in reverse order.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

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.

Quando sostituisci la batteria perdi tutti i dati ?

ale - Responder

Hi Ale,

when replacing the battery you won’t lose any data as long as you don’t damage any relevant components for data saving.

Dato che purtroppo non parlo italiano, ho creato questa risposta con l'aiuto di un traduttore. — Quando si sostituisce la batteria non si perderanno dati finché non si danneggiano componenti rilevanti per il salvataggio dei dati.

Dominik Schnabelrauch -

I just watched 2 YouTube guides on doing this and one used an adhesive ring strip while the other used glue from a bottle. Is one solution any more solid than the other?

Also, I don’t have an iOpener so would either isopropyl alcohol or a hair dryer be a good alternative for softening the back cover/battery adhesive?

Finally, I’ve seen and heard people using all sorts of things to pry out phone batteries ~ plastic pry sticks, metal pry tools, and even flat-edge screwdrivers. Which tool(s) are the safest and/or most effective?

TinkerJosh - Responder

Hi TinkerJosh, isopropyl alcohol (>97%) is a valid option for softening adhesive. A hairdryer will also achieve a good result for heating the adhesive. I would advise against using metal tools (such as metal spudgers or flat screwdrivers). To pry out the battery you are better off with opening picks and a plastic card. Either way, try not to puncture or deform the battery to avoid damaging it. Successful repairing

Tobias Isakeit -

Great instruction, Thanks. Is there a part # For the new adhesive gasket, and where can it be bought?

derek5 - Responder

You can actually replace the battery just fine stopping at Step 14. You dont need to take the bottom interconnect baord out at all. Just hold the interconnect ribbon up out of the way, and pry the battery out (carefully) as you would any other phone. The new one can then be refitted following the same method. I would also argue that this task doesnt deserve its “Moderate” dificulty rating… Its the abck cover and 9 screws. That’s all.

dragon2309 - Responder

Yes, stopping at step 14 worked for me too. It was easy to remove the battery with the interconnect ribbon held out of the way. Total time was one hour using an iOpener kit. The whole process was a lot simpler than I had expected.

Hi.

I had my battery changed due to bloating and everything works except I get no service unless the power cable is plugged in.

Any ideas where they should be looking as it’s had No Fault Found from two labs now?

Cheers

Phil Teague - Responder

Can someone help me out here, so I have a Huawei mate P20 Pro, and my current battery keeps losing charge and seems to be faulty. I had ordered a battery to replace the faulty one. I swapped out the battery, however, for some reason when I switch on the device it shows the Huawei logo and then switches off. It's so odd I even bought another battery and it does the same thing. But when I put back the original battery that came with the device, the device boots up normally. I feel as though I need to format my device or something, can anyone advise ?

Minhaz - Responder

Hi Minhaz,

sadly I do not have the perfect solution for you but here is some information from the Huawei service I found which might help you:

1. Use a USB cable to connect your phone to a charger or computer. Press and hold the Volume up and Power buttons for at least 30 seconds to enter eRecovery mode. Connect to an available Wi-Fi network and follow the onscreen instructions to restore your phone.

2. If a USB cable is not available, press and hold the Volume up and Power buttons for at least 30 seconds to enter Recovery mode, and then restore your phone to factory settings.

3. Connect your phone to a computer using a USB cable, then press and hold the Volume down and Power buttons for at least 30 seconds to enter Fastboot mode. Then, install HiSuite on your computer, then use HiSuite to restore your phone.

Please take note that your personal data may be erased during the process. Exercise caution when doing so and back up your important data first if your phone can be powered on.

I just replaced my battery following these instructions. The only problem I found was the top right side screw was covered by thick rubber (adhesive?) and I had to cut it away with a scalpel to get at the screw underneath. Other than that, it was pretty simple to follow. I used a hot air gun to soften the battery adhesive and it came off easily enough. For some reason the fingerprint scanner isn't recognised anymore. Although that may be a software issue as lots of people are complaining about this happening after software updates.

belfastgooner - Responder

i bought all the tools and parts but it doesnt include the battery adhesive or the back glass adhesive! cmon bruh do i gotta make another order now? cause all of it arrived already. why doesnt the guide include the process of closing it back up?

Grqfes - Responder

I just replaced my battery due to the old one being bloated and it won't seem to stay charging. Is there some hardware lock feature or could it possibly be reconnecting the connectors improperly? I checked twice to make sure they were in place but same problem.

I did this, the screen now won't turn on. the backlight still works, it worked when before I went to bed now nothing. what did I do wrong?

Thank you, this guida was great and I fully managed to change my battery. I would only suggest to use a lot of patience, the hardest part was actually to take off the battery due to all the glue. Good Luck to everyone else who will try this!

Eine sehr gute Anleitung. Allerdings kann man auf Schritt 16-18 verzichten; habe ich bis dato nie gemacht. Man muss nur darauf achten, das man die Folienkabel nicht scharf knickt beim zur Seite halten, wenn man den Akku aushebelt

Michael Buchholz - Responder

Thank you so much! I followed your instructions and everything worked out great! The battery removal was indeed the hardest part as I did not have the options to heat or dissolve the glue. I tried this during my lunch break at work. My p20 pro lives again.

Sharda j - Responder

Die Reparaturanleitung ist ausgezeichnet! Lediglich das Flachbandkabel in Schritt 14 kann beim neuen Akku etwas zu lange sein und muss daher vorsichtig gefaltet werden.

Es empfiehlt sich, eine Klebertube zu kaufen, um das Smartphone wieder abzudichten.
