Why is my charging discharging so fast? With normal use i get 3 extra charge from the case with the earbuds at around 20% . But i tried using the earbuds for around 2hrs and put it back in the case and still get 3 extra charge. I was expecting it to not consume a lot from the charging case since the earbuds still have around 80% of battery. What seems to be the problem with this issue?
