The best way to improve your phone's performance is to replace the battery if you discover that the Huawei Mate 50's battery life has decreased. The safest choice is to submit your phone to a professional repair facility, but if you have any technical know-how, you may also replace the battery on your own. Phonefix will give you thorough instructions and safety measures to help you finish the battery replacement procedure.
Why replace your Huawei Mate 50 battery?
Over time, mobile phone battery performance gradually declines, resulting in slower charging speeds or shorter battery life. If your Huawei Mate 50 has been used for some time, it may already be showing signs of battery aging. Replacing the battery is an effective way to restore your phone's performance and improve your user experience.
Pros and Cons of DIY Battery Replacement
Advantages:
• Cost savings: Compared to official repairs, replacing the battery yourself can save on repair costs.
• Self-control: DIY battery replacement allows you to better control the entire process and avoid waiting for repair times.
Disadvantages:
• Higher risk: Inexperienced users may damage other components during the disassembly process.
• Warranty issues: If your phone is still under warranty, disassembling the device may void the warranty.
Therefore, if you are confident in your abilities and prepared to handle potential risks, DIY battery replacement can be a worthwhile task.
List of Required Tools
Before starting the repair, you will need the following tools:
• Hot air gun/hair dryer: Used to soften the adhesive between the back cover glass and the phone frame.
• Suction cup: Used to easily pry open the back cover glass.
• Plastic pry tool/spudger: Used to disassemble various components to avoid damaging the phone.
• Phillips screwdriver set: For removing internal screws.
• Tweezers: For precisely removing small components.
• New battery (with adhesive): Ensure you use an original or high-quality replacement battery.
• New adhesive/sealant: Used to seal the back cover and ensure the phone's water resistance.
Step 1: Preparation
1. Turn off your Huawei Mate 50 and remove the SIM card
Before starting the disassembly, first turn off your Huawei Mate 50. After turning off the phone, use a SIM card ejector tool to remove the SIM card tray to prevent damage to the SIM card during disassembly.
2. Choose a clean working environment
To ensure a smooth repair process, choose a clean, well-lit area to work in. Ideally, work in an anti-static environment to avoid electrostatic discharge damaging the phone's internal components.
3. Check your tools
Make sure you have all the necessary tools. Missing tools may affect the repair process.
Step 2: Disassembling the Huawei Mate 50
1. Soften the back cover adhesive with a hot air gun
Take a hot air gun or hairdryer and direct warm air towards the edges of the Huawei Mate 50's back cover. The purpose of heating is to soften the adhesive between the back cover and the phone frame, preventing the glass from cracking during disassembly. Keep the heating temperature around 60°C, and avoid overheating.
2. Pry open the back cover
Use a suction cup to attach to the center of the back cover, then gently pull up to create a small gap. Then, use a plastic pry tool to slide along the gap and slowly pry open the back cover. Be careful to avoid damaging flexible cables, such as the fingerprint sensor and flash connections, during prying.
3. Remove the protective cover and disconnect connections
After removing the back cover, you will see several internal components. Use a Phillips screwdriver to unscrew the screws securing the protective cover, then carefully remove the protective cover. Next, disconnect the battery connector to safely remove the battery.
Step 3: Removing the old battery
1. Pry out the battery
The battery is usually secured to the phone frame with adhesive. Gently heat the edges of the battery with a hot air gun to soften the adhesive. Then carefully pry up the battery using a plastic pry tool. If the battery is very sticky, you can heat it a few more times until the battery can be easily removed.
2. Check the battery condition
After removing the old battery, carefully check the battery for any obvious swelling, leakage, or damage. If the battery is severely damaged, it must be handled carefully to avoid battery leakage causing harm to the environment or other components.
Step 4: Installing the new battery
1. Prepare the new battery
After taking out the new battery, apply an appropriate amount of adhesive evenly to the bottom of the battery. Ensure that there is not too much or too little adhesive to avoid overflow affecting other components.
2. Connecting the new battery
Align the new battery with the battery slot inside the phone, gently insert it, and ensure it is in the correct position. Use tweezers to connect the battery cable to the connector on the motherboard, ensuring a secure connection.
Step 5: Reassembling the Phone
1. Reconnecting other components
After installing the new battery, reconnect the other internal components of the phone in order, including the charging port, fingerprint sensor, battery indicator light, etc. Ensure that each connector is properly connected.
2. Installing the protective bracket and securing screws
Reinstall the protective bracket that was previously removed, and use a Phillips screwdriver to tighten the screws of the bracket. Ensure that the bracket and screws are securely fastened to prevent the internal components of the phone from becoming loose.
Step 6: Sealing the Back Cover
1. Applying new adhesive
Apply new adhesive glue evenly to the edges of the phone frame. When applying, ensure that every gap is covered with adhesive.
2. Reinstalling the back cover
Align the back cover with the phone frame and gently press it to ensure a perfect fit between the back cover and the phone frame. Apply even pressure to avoid glass breakage.
3. Securing the back cover
Secure the back cover with rubber bands or clips until the adhesive is completely cured. Typically, the adhesive takes about 30 minutes to cure.
Step 7: Final Check
1. Checking phone functionality
After reassembly and sealing, turn on the phone to check if it starts normally. Specifically, check if the battery is charging properly, and if the screen, fingerprint recognition, and charging port are working correctly.
2. Charging and calibrating the battery
To ensure optimal performance of the new battery, it is recommended to fully charge the battery and perform a complete charge and discharge cycle. This helps in battery calibration.
It takes some hand dexterity and an understanding of the inside workings of the phone to replace the Huawei Mate 50 battery.
