Recently, The Big N announced they would be releasing an updated model of the Nintendo Switch powered by an upgraded Tegra mobile processor. This new Switch doesn’t offer any additional processing power for games (that we know of), but it does deliver significantly improved battery life. You can play Zelda: Breath of the Wild for around 5.5 hours on the new Switch, a major improvement over the 3 hours you got on the original model.

Unfortunately, Nintendo has been rather cagey about the release of the new Switch. They’ve quietly been rolling it out to retailers, but the new model’s packaging doesn’t clearly differentiate it from older models. So, what if you recently walked into a store and unknowingly purchased an older Switch when a better model was sitting right beside it? Are you screwed? Surprisingly not!
