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, one place they don’t excel is battery life.
Any halfway intensive iPhone user will recharge their phone almost
every couple of days.
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 14 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. 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
4. 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
5. 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
6. 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
7. Turn Data Push Off
The iPhone can be set to automatically suck email and other data
down to it or, for some kinds of accounts, have data pushed out to it
whenever new data becomes available. You’re probably realized by now
that accessing wireless networks costs you battery life, so turning data push off,
and thus reducing the number of times your phone connects to the
network, will extend your battery’s life. With push off, you’ll need to
set your email to check periodically or do it manually (see the next
tip for more on this).
Find it in Settings -> Mail, Contacts, Calendar -> Fetch New Data -> Slide to Off
8. Fetch Email Less Often
The less often your phone accesses a network, the less battery it uses. Save battery life by setting your phone to check your email accounts less often.
Try checking every hour or, if you’re really serious about saving
battery, manually. Manual checks means you’ll never have email waiting
for you on your phone, but you’ll also stave off the red battery icon.
Find it in Settings -> Mail, Contacts, Calendar -> Fetch New Data -> Select Your Preference
9. Auto-Lock Sooner
You can set your iPhone to automatically go to sleep – a feature known as Auto-Lock
- after a certain amount of time. The sooner it sleeps, the less power
is used to run the screen or other services. Try setting Auto-Lock to 1
or 2 minutes.
Find it in Settings -> General -> Auto-Lock -> Tap your Preference
10. Turn off Equalizer
The iPod app on the iPhone has an
Equalizer feature
that can adjust music to increase bass, decrease treble, etc. Because
these adjustments are made on the fly, they require extra battery. Turn
the equalizer off to conserve battery. This means you'll have a
slightly modified listening experience - the battery savings might not
be worht it to true audiophiles - but for those hoarding battery power,
it's a good deal.
Find it in Settings -> Music -> EQ -> Tap off
11. Do Less-Battery-Intensive Things
Not all ways to save battery life involve settings. Some of them
involve the way you use the phone. Things that require the phone be on
for long periods of time, or use a lot of system resources, suck the
most battery. These things include movies, games, and browsing the web.
If you need to conserve battery, limit your use of battery-intensive
apps.
12. Sleep and Wake Less
Constantly putting your phone to sleep and waking it up will drain
battery life. Of course these functions are common parts of using the
phone, but you can also be judicious in your turning on and off of the
phone and save battery life at the same time.
13. Buy an Extended Life Battery

If all else fails, just get more battery. A few accessory makers like
mophie and Kensington offer extended life batteries for the iPhone. If
you need so much battery life that none of these tips help you enough,
an extended life battery is your best bet. With one, you’ll get days
more standby time and many hours more use.
14. iPhone 4S & iOS 5: Turn Off Other Location Settings
Use this tip if your iPhone 4S or devices upgraded to iOS 5 are
burning through battery life too quickly. It's probably a software bug,
so Apple may fix it and this tip may go away, but in the meantime,
here it is.
A number of additional location services introduced in iOS 5 seem to
be draining battery too quickly. Turn them off and you should regain
some battery life.
Find it in Settings -> Privacy -> Location Services
-> System Services -> Turn off Diagnostics & Usage,
Location-Based iAds, and Setting Time Zone
