iPhone Duo: Activate StandBy Mode When Not Charging

Unlike other iPhones, iPhone Duo can enter StandBy mode without a charger. You only need to fold the Duo in half or in a tent orientation and you'll see widgets, music, calendar, weather, and more – even when you're away from a power source.

Here's how to set up iPhone Duo StandBy mode without a charger:

1. Open Settings, tap StandBy, and make sure StandBy is turned on.
2. On the same screen, tick off the folding positions you want to enable, and make sure the Only While Charging toggle is off.
3. Now, lock your iPhone Duo, partially fold it like a book or a tent, and set it down on a flat surface.

StandBy will start automatically in either supported position. When the display lights up, tap the current face, then swipe left or right to change it to a different style and content mode. Some faces also support swiping up and down to change content.

If you find StandBy to be a power drain, simply turn on Only While Charging to ensure the mode is restricted to charging sessions in future.
