05 Battery and storage
IOS 9 HAS GREAT NEW WAYS TO MANAGE YOUR DEVICE’S STORAGE AND BATTERY
CONSERVE POWER
Smartphones are power hungry, there’s no way around that with bright touchscreens and plenty of apps running. But it’s good to see Apple turning its attention to battery management proper. Low Power Mode disables certain aspects of your iPhone, including background app refresh, so you don’t have to go around turning o features any more. It can extend usage by a few hours, and kicks in (as an option o ered in an alert) when your iPhone reaches 20% of its battery capacity. e battery meter at the top-right of the screen turns yellow to indicate Low Power Mode is enabled. e feature can be turned on manually at any time in Settings > Battery.
MANAGE YOUR USAGE
In Settings > Battery, you can view what hogs the battery. ere are two options, Last 24 Hours or Last 7 Days. ey display the proportion of battery life used by each app in that time. Tap the clock icon on the right to see the duration that apps were using battery, both while on-screen and in the background.
EXITING LOW POWER MODE
You can turn o Low Power Mode manually, of course, in Settings. However, when battery power reaches 80% on charging your device, Low Power Mode will be turned o automatically, returning your iPhone to full throttle.
MONITOR BATTERIES
Among a slew of subtle changes to Noti cation Center, on an iPhone only you can check battery statuses in the Today view. e Batteries widget shows power levels of your phone and Bluetooth accessories, such as headphones or an Apple Watch. To enable it, scroll to the bottom of the Today view, tap Edit, then tap the + next to the widget’s name. e Batteries widget is not available if a Bluetooth accessory is not paired with the iPhone.
