Flip Your iPhone to Save Battery

Flip your iPhone to drain less - an old, effective trick has resurfaced online, which genuinely extends the life of the smartphone. The iPhone has a built-in feature called Facedown Detection. It works simply: if the phone is screen-down, it doesn't light up with every notification. This is particularly useful when a lot of push notifications come in during the day. Even if the iPhone is just lying on the table, each push turns on the display and consumes battery. But if you keep it flipped, you can save up to 10–15% of the battery each day.
