  • Extended Charge Time: If your phone takes significantly longer to charge.

Preparing for Battery Replacement

  • Data BackupBefore any repair, ensure your data is safe. Use cloud services or save to a computer.

  2. Open the Device: Based on your phone model, either remove the back panel or unscrew to access the internals.
  3. Locate and Disconnect: Find the battery connector and carefully disconnect it.
  4. Remove the Old Battery: It might be adhered, so use plastic pry tools to gently lift it.
  5. Insert New Battery: Place your new battery in, connecting it to the phone.
  6. Reassemble the Device: Reattach the back panel or screw the device back together.
  7. First Charge: Charge your phone fully before first use.

Battery Maintenance Tips

  • Avoid Extreme Temperatures: Excessive heat or cold can diminish battery life.
  • Regular, Moderate Charging: Instead of 0 to 100%, try charging between 20% and 80% for longevity.
