My left EarFun Air Pro 4 earbud drains 10% faster, even though I've only been using it for a week. I’ve already reset it, but it didn’t help. Is this normal? Could it be due to the master-slave system? Or is a 10% difference in battery life common?

The power consumption of the left and the right earbud is different due to TWS MCSync technology. It is normal that the battery of the master earbud drains off faster than the other earbud within 1 hour.
