Important Battery Information

iFixit Repairability Score:
The Huawei Mate 20 Pro received a repairability score of 4 out of 10 from iFixit . This indicates that battery replacement requires patience, proper tools, and technical skill. The main challenges include:

• Screen Removal: The curved OLED display is difficult to remove without cracking, requiring multiple heat guns and up to 11 opening picks 

• Water Resistance: The IP68 seal will be compromised and must be properly reapplied with new adhesive 

• Component Access: The battery is secured beneath multiple components including the wireless charging coil and NFC module 

First-Time Use:
New Lithium Ion batteries must be FULLY CHARGED and FULLY DISCHARGED 2 to 3 times before being FULLY CONDITIONED . Please remember that a new Lithium-Ion battery's full performance and longevity is only achieved after 2 to 3 complete charge and discharge cycles. After you go through 2 to 3 cycles, you'll never have to condition your battery again! 

Battery Calibration:
For optimal performance, follow this calibration procedure :

1. After installation, charge the battery to 100% and continue charging for at least 2 more hours

2. Use the device until it shuts off due to low battery

3. Finally, charge it to 100% uninterrupted

4. This helps the phone's software accurately read the new battery's capacity

Storage and Care:

• Do not expose the battery to flame or excessive heat

• Keep the battery dry and avoid immersion in or exposure to water

• Discontinue use immediately if you notice any change in the battery, such as discoloration or deformation

• To maintain battery health, charge when the level drops to 15-25% rather than letting it drain completely to 0%

• If storing for extended periods, keep at approximately 50-60% charge in a cool, dry place

Swollen Battery Warning:
If your old battery is swollen, take appropriate safety measures. For safety, discharge the battery to below 25% before removing the phone to reduce the risk of thermal incident if the battery is accidentally damaged during the repair . Handle with extreme caution and avoid applying pressure.

Proper Disposal:
Lithium-Ion batteries should never be incinerated or thrown into household trash. Always recycle old batteries through authorised electronic waste recycling centres. Many places that sell phone batteries will also accept them back for recycling.

Installation Information

This is an advanced-level repair requiring professional installation or significant technical skill. The Huawei Mate 20 Pro features a non-removable battery sealed within a complex assembly with an IP68 water resistance rating .

Many premium battery kits come with a complete set of repair tools to assist with the replacement, including screwdrivers, opening picks, spudgers, and suction cups .

Important Safety Precautions:

• Professional installation by a qualified technician is strongly recommended

• If you attempt DIY installation, follow the detailed iFixit guide carefully 

• Opening the Huawei Mate 20 Pro will damage the waterproof seal—if you don't replace the adhesive, the phone will lose its IP68 rating 

• Never puncture, deform, heat, or throw batteries into fire

• If the battery is swollen, handle with extreme care and avoid applying pressure

• Use only plastic tools when working near the battery—metal tools can puncture the battery and cause a fire or explosion

• Disconnect the battery before attempting any repair

• Use ESD (electrostatic discharge) protection

• Keep defective batteries away from children and pets immediately

• Properly dispose of old batteries at an authorised electronic waste recycling centre

THE REPAIR PLUS strongly recommends having this component installed by a qualified technician with experience in Huawei smartphone repairs. We are not responsible for any damage caused during installation.
