I have an issue with the battery of my right eabud. After about 15 minutes of use it tells me it's empty, while it is not. When I put it back into its charging case and take it out after a few seconds it tells me its actual percentage and after charging it for 30 seconds more it's supposedly back to 100% just to last me 15 minutes and die again. I updated the earbuds in hopes that this would fix my issue but it did not. I've seen other posts on this subject but am yet to find a solution, though I really hope there is one as it would be a shame for my €200 earbuds to die because of something out of my control just after the warranty period has passed.
