Anker Soundcore Life P2 Right Earbud Battery

I just bought Anker Soundcore Life P2 a few days ago and I am noticing the right earbud is draining faster than the left bud (Both Fully Charge Fine and I still get 6-7 hours but it’s frustrating) I listen to classic rock and hip-hop music with these. I use these buds on different devices and switch them around across my Windows 10 Desktop and Galaxy S8. I don’t know if this is normal or if there is a defect with my pair?

I have noticed the same issue! Would be great to hear an official reply on this.
