That was the first thing that Apple told me to do, but said NOT to use alcohol. There is a battery in that case, and alcohol is flammable, and conducts electricity. And, yes, the case will continue to charge buds that are also not disconnected to the Bluetooth source. The case then ends up depleted, as well as the bud(s). But, so far (knock on wood) leaving the case plugged in 24/7 *seems* to be working very well. I use a 'microfibre' wipe on the buds, and the case, and leave it plugged in, and so far, no dead buds. (I'm sure they are monitoring this, and will act up now) It's been nearly 2 weeks! I'm just waiting for the next time the buds show up dead. I know it's coming...
I offered that the 'bug' seems to be in the charging circuit, and the pins not being long enough to make contact if the buds are slightly out of position. I am wondering if the new PBP's have longer pins. I can't forget suggesting that the pins be longer, and the surprised reaction from the Apple person on the phone. '*gasp* Well, that might be a solution'. *sigh*
The damn things fit so well, and the fidelity is great. It's keeping them working that is making it really hard to recommend them...
