Anyone who’s used an iPhone for even a few days has
discovered that while these phones are more powerful, and more fun, than
perhaps any other cell or smart phone, that fun comes with a price: battery
use. There are
ways to conserve iPhone battery life, but many of them involve turning off
services and features, which makes it a choice between all the cool things that
the iPhone can do and having enough juice to do them.
Here are some tips to help you extend your iPhone battery life.
1. Turn
on Auto-Brightness
The iPhone has an ambient light sensor that adjusts the
brightness of the screen based on the light around it (darker in dark places,
brighter when there's more ambient light) to both save battery and make it
easier to see. Turn Auto-Brightness on and you’ll save battery
because your screen will need to use less power in dark places.
Find it
in the Settings app -> Brightness & Wallpaper -> Auto-Brightness On
2. Reduce
Screen Brightness
You can control the default brightness of
your iPhone screen with this slider. Needless to say, the brighter the default
setting for the screen, the more battery it requires. Keep the screen dimmer to
conserve more of your battery.
Find it in Settings -> Brightness &
Wallpaper
3. Stop
Motion (iOS 7)
One of the coolest features of iOS 7 is called
Background Motion. It's subtle, but if you move your iPhone and watch the app
icons and background image, you'll see them move slightly independently of each
other, as if they're on different planes. This is called a parallax effect.
It's really cool, but it also drains battery. You may want to leave it on to
enjoy the effect, but if not, turn it off this way:
Settings
-> General -> Accessibility -> Reduce Motion -> move slider to
green/on
4.
Disable Dynamic Backgrounds (iOS 7)
Another
neat feature introduced in iOS 7 is animated wallpapers that move underneath
your app icons. These dynamic backgrounds offer a cool interface flourish, but
they also use more battery than a simple static background image. Dynamic
Backgrounds aren't a feature you have to turn on or off, just don't select the
Dynamic Backgrounds in theWallpapers & Backgrounds menu.
5. Turn
Bluetooth Off
Bluetooth wireless networking is especially useful for
cell phone users with wireless headsets or earpieces. But
transmitting data wirelessly takes battery and leaving Bluetooth on to accept
incoming data at all times requires even more juice. Turn off Bluetooth except
when you’re using it to squeeze more juice from your battery.
Find it
in Settings -> Bluetooth -> Move Slider to Off
6. Turn
Off 3G/4G
The iPhone 3G and later models can take advantage the
speedy 3G and 4G LTE cellular phone networks. Not surprisingly, using 3G, and
especially 4G LTE, requires more battery life to get the quicker data speeds
and higher-quality calls. It’s tough to go slower, but if you need more
battery, turn off 3G or LTE and just use the older, slower
networks. Your battery will last longer (though you’ll need it when you’re
downloading websites more slowly!).
Find it
in Settings -> General -> Cellular -> Slide Enable 3G to Off on some
models or Enable LTE to Off on the iPhone 5 or newer
7. Keep
Wi-Fi Off
The other kind of high-speed network that the iPhone can connect to is Wi-Fi. Wi-Fi is even
faster than 3G, though it’s only available where there’s a hotspot (not
virtually everywhere like 3G). Keeping Wi-Fi turned on at all times in hopes
that an open hotspot will appear is a sure way to drain your battery life. So,
unless you’re using it right this second, keep Wi-Fi turned off.
Find it
in Settings -> WiFi -> Slide to Off
8. Turn
Off Location Services
One of the coolest features of the iPhone is its built-in GPS. This allows your phone to know
where you are and give you exact driving directions, give that information to
apps that help you find restaurants, and more. But, like any service that sends
data over a network, it needs battery power to work. If you’re not using Location
Services, and don’t plan to right away, turn them off and save some power.
Find it
in Settings -> Privacy -> Location Services -> Slide to Off
