Battery Life
The fact that Nintendo has managed to get full-fledged console games like Skyrim running on a portable console is seriously noteworthy. However, this only becomes a really impressive feature if the hardware can support and sustain this portable play for extensive periods of time.
That’s why battery life is such a huge factor for the Switch. If you can’t play Skyrim on the portable for more than a couple of hours, it quickly loses its appeal. Yes, a two-hour life may be fine for someone who just uses it when taking a short commute to work, but for those wanting to use it on a flight as was shown in the trailer, this may not cut it. With mobility being such a fundamental aspect of the Switch, battery life could ultimately be what makes or breaks the platform.
