I would be quite disapointed with these battery life, it's pretty subpar compared to current handhelds.

The docked and undocked performance theory doesn't make sense.

First, sources have already mentioned that there is nothing special about the dock, mainly just extra ports. At best, one can hope this thing to have some sort of wireless hdmi/streaming.

Second, developers would have to take into consideration the difference in performance between for each mode to take advantage of it. It means more work for them if they do. It adds unneccesarry complexity that goes against Nintendo's goal of easier/simpler software development.

Third, it creates inconsistent user experience, making the product seem lower in quality. Throttling is seen as something negative for mobile/portable devices.

Yeah, I still want more. I rarely buy third party battery packs, but for this, I might.
