I bought an airpod some days ago, it's not even up to three days now it's not connecting with my phone anymore. I slept off while charging it, I guess it overcharged. Could this be the cause?

It's of inferior quality that's why. Airpods should stop charging when it's fully charged, there's actually nothing like over charged.

I thought as much, it stopped connecting. The case everything is still intact and clean, it's not even up to to 3 days yet. It's a cloned airpod sha, my money is gone just like that..
