I’ve been getting this more and more as time goes by. Nowadays I unlock my iPhone and make sure both PowerBeats are charging before I close the case. But occasionally, even if they were both charging before closing the case, the next day I'll pop them out only to find that the Left is down to 40% while the Right is fully charged.
It can be quite difficult to even get them to charge in the first place. Sometimes I have to pull them out and stick them back in half a dozen times before they’ll start charging. One thing I’ve found is that rubbing my finger on the connectors just once is often enough to get the connection working again.
The problem with them not powering on is even more irritating, because I don’t usually take my case with me when I head to the gym or head out for a run. Both PowerBeats may work fine when I first put them on, but then I take them out of my ears while driving, and when I put them back on, sometimes the Right one won’t wake. And since the only way to force a wake is to put it back in the case and pull it out, I’m SoL.
"Everything automated” is great when it actually works. But when it’s so unreliable, it’s a huge nuisance. I’d rather have a power button than have to babysit this “automated” process. Likewise with the magnets that are not even strong enough to keep the PowerBeats plugged-in.
