Use this guide to replace a worn-out or dead battery in your Huawei P30 Pro.
Opening the Huawei P30 Pro will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water-protection.
If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
Although it is possible to remove the battery without removing the main flex cable with the charging port, we recommend to do so to avoid damage to surrounding components.
You’ll need replacement adhesive to reattach components when reassembling the device.

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.

Hardware work is accurate. However, replacing original battery to Huawei P30 Pro it will generate a bootloop. Add next step to avoid this please. How to calibrate battery? Actually, how to pair new battery with the mainboard? Same problem occurs to P40lite and perhaps to Mate 30
I also have the same problem, did you find a solution

you have to have the old battery first. I tried 2 batteries and I had the same problem you mentioned. Just put the new battery in its place and don't plug the wear of it, instead, you are going to put the old battery over the new battery and plug the wear of the old battery and turn on the device with the power cable on. Once it's turned on unplug it quickly and plunge the new battery wire. I know it sounds silly but I tried it and it worked. I think what happened is that you trick the phone by doing that. Btw, its hard to have the 2 batteries over each other but keep holding them.

Hi, regarding the battery replacement, you will need to have the original battery serial number and copy it to the new one.
This can be done using ChimeraTool, but bear in mind you need to know what is your current firmware version. So before repair write down your firmware version ( example: VOG-L09 10.1.0.151(C636e9r2p4) ) and if it’s with the most recent update Chimera might not have it yet, so you will need to wait until they update.
Hope this helps!
Can I contact you for help?
