Step-By-Step Guide To Changing The Battery

Changing the battery in your Samsung Galaxy S7 is straightforward. Follow the steps below to complete the process efficiently.

Powering Down The Device

Start by powering down your Galaxy S7. Press and hold the power button until you see the power menu. Tap “Power off,” then confirm your choice. This prevents any electrical shorts while you work.

Removing The Back Cover

Use a heat gun or hair dryer to warm the edges of the back cover for about 30 seconds. The heat softens the adhesive, making it easier to remove. Next, insert a plastic pry tool into the gap between the back cover and the phone. Carefully slide the tool around the edges to detach the cover. Lift it off gently without forcing it.

Disconnecting The Old Battery

Locate the battery connector on the motherboard. Use a precision screwdriver to remove the screws securing the connector cover. Gently lift the cover with tweezers, then disconnect the battery by pulling the connector away from the motherboard.

Installing The New Battery

Take your new battery and connect it to the motherboard. Ensure it’s aligned properly with the connector. Press down firmly until you feel it click into place. Reattach the connector cover and secure it with the screws you removed earlier.

Reassembling The Device

Position the back cover onto the device, ensuring it’s aligned correctly. Press down firmly along the edges to bond the adhesive. If necessary, apply a little heat to help seal the cover. Power on your Galaxy S7 and check that the new battery is functioning properly.

Tips For Maintaining Battery Health

Maintaining battery health can extend the life of your Samsung Galaxy S7. Here are essential practices to keep your battery performing well.

Proper Charging Practices

Charge your Galaxy S7 when it drops to around 20% for optimal lifespan. Avoid letting it drop below 10%. Charge it up to 80-90% rather than 100% if possible. Frequent full charges can lead to wear over time. Use the original charger to ensure sufficient power and avoid faster degradation. Try not to use your phone while it’s charging. This minimizes heat generation, which can damage the battery.

Avoiding Extreme Temperatures

Keep your device away from extreme temperatures. Temperatures above 95°F (35°C) can harm battery health. Avoid exposing your phone to freezing temperatures below 32°F (0°C), as this can cause temporary capacity loss. Always store your Galaxy S7 in a cool, dry place. If you’re outside in extreme heat, store the device in a shaded area or take breaks from using it. This approach safeguards the battery’s performance and longevity.

Troubleshooting Common Issues

After replacing the battery in your Samsung Galaxy S7, you might face some common issues. Here’s how to address them effectively.

Device Not Powering On

If your device doesn’t power on after replacing the battery, follow these steps:

1. Check Battery Installation: Ensure the new battery is seated properly in the compartment. The connector should fit securely in place.
2. Inspect the Power Button: Make sure the power button isn’t stuck. Press it firmly to see if it responds.
3. Force Restart the Phone: Press and hold the power button and the volume down button simultaneously for about 10 seconds. This can help reset the device.
4. Connect to Charger: If it still doesn’t turn on, connect the phone to a charger for at least 15 minutes. A completely drained battery may take time to charge enough to power on.

Battery Not Charging

If your new battery isn’t charging, consider these troubleshooting steps:

1. Verify Charging Cable and Adapter: Use a different charging cable and adapter to rule out defects. Damaged cables can prevent charging.
2. Examine Charging Port: Check the phone’s charging port for any debris or lint. Use a soft brush or compressed air to clean it gently.
3. Reinstall the Battery: Power off the device, remove the battery, and reinsert it. Ensure it’s connected firmly to the motherboard.
4. Test with Another Charger: Sometimes, chargers may malfunction. Test with a known working charger to see if the issue persists.

These steps should help you troubleshoot any common issues after your battery replacement.
