For me, that's disappointing. It means that a year or two into battery wear you'll be tethered to an outlet.

The situation looks even more dire after reading this quote.

Batteries don't tend to degrade like they used to. The chips that charge and discharge them are a lot more sophisticated. Most batteries do well for 2.5-3 years these days.

Obviously the dock can keep the machine powered while playing, so there is at least one.

Other outlets were not having the same issues. I suspect a cable or device issue.
