Files documented by the Federal Communications Commission (FCC) tells us that the Nintendo Switch will not have a replaceable battery.
This might be bad news for some since you cannot swap it out for something that has a longer battery life. Not to mention it will hard to replace the battery if it gets broken. You may need to buy another console entirely.
We won’t know the battery life for the Nintendo Switch until January 12th. The event in January will also tell us the slate of launch games and the specifications of the console.
