5. Setup & Installation

The repair kit includes a detailed instruction sheet to guide you through the step-by-step installation process. Please refer to this sheet for visual aids and specific instructions for your device. A general overview of the process is provided below:

1. Preparation: Power off your phone completely. It is recommended to discharge the battery below 25% before starting to reduce the risk of thermal events if the battery is accidentally damaged.
2. Heat the Back Cover: Use a hair dryer or a heat gun to gently warm the edges of the phone's back cover. This softens the adhesive, making it easier to remove.
3. Open the Back Cover: Carefully use the included suction cup and opening tools (spudgers) to pry open the back cover. Work slowly and gently to avoid damaging the cover or internal components.
4. Remove Screws: Locate and remove the screws securing the mid-frame or battery bracket. Keep track of screw locations as they may vary in size.
5. Disconnect Old Battery: Carefully disconnect the old battery's flex cable from the motherboard using a plastic spudger. Do not use metal tools to pry the battery connector.
6. Remove Old Battery: Gently pry out the old battery. If it is heavily adhered, apply a small amount of isopropyl alcohol around the edges to loosen the adhesive. Be extremely careful not to puncture or bend the old battery.
7. Install New Battery: Apply the new battery adhesive (if provided) to the phone's frame. Place the new ASDAWN EB-BG985ABY battery into position, ensuring it sits flat.
8. Connect New Battery: Reconnect the new battery's flex cable to the motherboard.
9. Reassemble: Reinstall any brackets and screws. Carefully reattach the back cover, ensuring the adhesive seals properly. You may need to apply gentle heat again to help the adhesive bond.
10. Final Check: Power on your phone to ensure it functions correctly.

Note: If you are unsure about any step, it is recommended to seek professional assistance or refer to online video tutorials specific to your phone model.

6. Operating Instructions (First Use & Charging)

To achieve the best performance and longevity from your new ASDAWN battery, follow these initial charging guidelines:

• Initial Discharge: For the first three times, use your phone until the battery is completely drained and the phone shuts off.
• Full Charge: After each full discharge, charge the battery completely to 100% without interruption.
• Optimal Performance: The battery's full performance and longevity are typically achieved after 3 to 5 complete charge and discharge cycles.
• Charger Usage: Always use the original charger and cable provided with your phone for optimal and safe charging.

7. Maintenance

Proper maintenance can extend the life of your battery:

• Avoid extreme temperatures (hot or cold) as they can degrade battery performance.
• Do not leave your phone charging for extended periods after it reaches 100%.
• If storing the phone for a long time, charge the battery to about 50% to prevent deep discharge.
• Use only compatible and certified charging accessories.

8. Troubleshooting

If you encounter issues after battery replacement, consider the following:

• Phone Not Turning On: Ensure the battery flex cable is securely connected to the motherboard. Try charging the phone for at least 30 minutes before attempting to power it on.
• Battery Not Charging: Verify that the charging port is clean and undamaged. Ensure you are using a functional charger and cable. Recheck the battery connection inside the phone.
• Rapid Battery Drain: Allow for 3-5 full charge/discharge cycles for the battery to calibrate. Check for background apps consuming excessive power. If the issue persists, re-verify the battery connection.
• Phone Overheating: Discontinue use immediately. Ensure the battery is properly seated and not damaged. If overheating continues, disconnect the battery and seek professional help.
