Airpods Pro battery percent
Hello, I have recently noticed that my AirPods Pro have a 15% battery difference between them. I usually use them to go to the gym and after a few hours just before storing them they have a difference of 15% between them. Is this normal? Both have 100% when taking them out of the box, curiously the first one I take out of the box is the one that ends with the least battery, if I take out the R first it ends with 15% less battery, I invest the order and take out the L first then the same thing happens with this one, it ends with 15% less battery, so I rule out that one What would be the explanation for this? I bought them in March 28, 2021, they haven't been used for a year yet. I think 15% is a big difference. The other question is the low battery sounds, I think it sounds once with 10% and then just before they turn off they sound again when they have approximately 5%, is this correct?
