iOS 9 is packed with all kinds of great features and one of the most useful is a new low power mode that triggers when your battery gets to 20%. Wired took a look at exactly how much extra time you should be able to get out of your phone with this mode enabled.
When your phone drops to both 20% and 10%, you’ll get a notification asking if you want to enable Low Power Mode (you can also enable it manually whenever you want in Settings > Battery). This mode slows down CPU speed and disables unessential features like Background App Refresh, Bluetooth, motion effects, and more. Everyone uses their phone differently and because of that, it’s difficult to figure out exactly how much battery power you’ll save with it enabled because everyone’s usage is so different. However, Wired did at least get a general idea of what most of us can expect:
This means that if the Low Power mode uses 70 per cent of the power in standard mode, the battery should last 1.43 times as long. A 14 hour battery life would be 20 hours. That’s not too bad. I can live with a 20-hour battery life. Of course, the iPhone only suggests you turn on Low Power mode when you get to 20 per cent battery life. In that case, the extra time is about an hour.
That’s right around what Apple suggested it’d be, which is good news for anyone hoping to squeeze a little more power out of their phone before it dies. Head over to Wired for a full breakdown of how they did the tests and the maths behind it.
