Um, the way Nintendo showed off at their reveal. One at a time, then one with both hands. And no such comfort grips I've seen for these can be used while having them attached to the tablet, or docked. So their usability is limited at best. 20 hours isn't bad in and of itself, but it is a total cop out to make a trip to set them in and not be able to charge them through it. As it stands, without buying the optional grip, I have to ritualistically unplug and replug them in to the tablet every time if I don't want to spend more money. And it still doesn't solve the size problem for me. I basically need like, a switch XL. Or at the least, a switch with a replaceable battery design change, that enables third party extended battery upgrades for them. At least with the latter design change, I won't feel like I'm just renting the console at full price, when the time finally comes to get one.
