Step-by-Step Battery Replacement
Preparation
Before you start, ensure your device is powered off and remove any protective cases. Also, backup your data to prevent any loss during the process.
Removing the Back Cover
Use the suction cup to gently pull the back cover off. Start from the bottom, as the top is secured by clips. You might need to use a heat gun or iOpener to soften the adhesive first.
Disconnecting the Battery Connector
Underneath the back cover, you'll see the battery connector. Use a plastic opening tool to carefully pry it up and disconnect it from the motherboard.

Removing the Old Battery
Now, use the plastic opening tools to carefully pry the battery out of its recess. Be gentle to avoid damaging the battery or the device. Once loosened, use tweezers to pull it out.
Installing the New Battery
Before installing the new battery, clean the battery contacts and the recess to ensure a good connection. Align the new battery with the recess and press it in gently but firmly. Ensure the battery connector is properly aligned and connected.
Reassembling Your Device
Replace the battery connector, ensuring it's properly seated. Then, use the new adhesive strips to secure the back cover. Apply gentle pressure to ensure a good seal.
Post-Replacement Care
After replacing your battery, charge it to 100% and let it discharge completely a few times to calibrate the battery meter. Also, avoid exposing your device to extreme temperatures to prolong your new battery's life.
If you're unsure about any part of the process, don't hesitate to consult a professional. Replacing your Galaxy S6 battery can significantly improve your device's performance, but it's crucial to do it safely and correctly.
