My nb10 are only a year old and ever since I’ve owned them they randomly jump from 70% battery to 10% when in use on my iphone s max. It’s not instant. It’s on par with how long it should last. I just get zero information on power level between 70% and 10% and it’s quite annoying. So I always have to overcharge the battery or gamble that they will last.
Am I the only one experiencing this?
