Nintendo Switch's battery only uses 2% charge in eight hours of sleep mode

The Switch’s battery seems to be better than many expected it to be. According to Ars Technica’s preview, the console’s charge went from 100% to 98% after spending eight hours in sleep mode. This is indeed a good sign to those concerned about the battery life on the console, but rechargeable batteries are notorious for wearing down over time though, so take with a grain of salt.

Battery life so far conforms to Nintendo’s stated specs—I can get about three hours of portable Zelda play on a full battery charge, depending on the screen brightness. The included AC adapter seems to fill about 1 percent of the battery per minute (give or take) when the system is in sleep mode (that mode is very power conscious, incidentally—after eight hours in “sleep,” a fully charged battery had only drained to 98 percent).
