00:00There is a high energy battery on each side. Custom silicon and algorithms handle all of
00:06the charging, discharging, and rebalancing. So these two batteries operate seamlessly
00:11as one. The result is an impressive all-day battery life. You get up to 31 hours of video
00:19playback when using the inner display and a massive 44 hours when using the outer display.
00:25And with our new battery usage model, iPhone Duo provides up to 24 hours per charge
00:31when using both screens equally. It also supports fast charging, up to 50% in around 20 minutes,
00:39and gives you up to 5 hours of video playback when using the outer display after just 5 minutes of
00:45charging. Bringing iPhone Duo to life has involved some of the most complex and innovative engineering
00:52we have ever done.
