If you're finding that your soundcore C40i earbuds are not holding a charge or are draining too quickly, you can try the following suggestions to fix them. In this article, we'll walk you through some of the steps to resolve battery issues with your C40i earbuds.
1. Check for Debris: Ensure that the case's charging port and the charging cable's terminals are clean and free of any debris. Dirt or foreign particles can obstruct the connection and prevent charging.
2. Try a Different Charging Cable: If cleaning doesn't help, try a different charging cable. We recommend using the original cable that came with the product. If you are in fact using the original cable when the issue occurs, try a third-party cable.
3. Verify Charging Head Output: Sometimes, the charging adapter may not provide sufficient current. Check the output current of your charging adapter and make sure it matches or exceeds the input current specified on the charging case (5V/0.5A).
4. Inspect Charging Case Pins: Examine the pins inside the charging case. If you notice any debris or dirt, clean it promptly.
5. Check for Pin Misalignment: Ensure that the pins in the charging case are not recessed or misaligned. If the pins are recessed, apply a small amount of alcohol and gently poke the pins with a toothpick or tweezers. Once the pins pop out, wipe the area dry and the earbuds should function normally.
6. Clean Earbud Pins: Inspect the pins on the earbuds. If they appear dirty, clean them with alcohol to remove any grime or residue."
