[IPhone Battery maintenance tips]
Paying attention to just a few common sense pointers will pay off with
a longer battery lifespan and battery life for your iPhone. The most
important thing is to keep your iPhone out of the sun or a hot car
(including the glove box). Heat will degrade your battery?s performance the
most.
Some Terms You Need to Understand
?Battery life? means the time your iPhone will run before it must be
recharged. ?Battery lifespan? means the total amount of time your
battery will last before it must be replaced.
iPhone Temperate Zone. Your iPhone works best from 32° to 95° F. You
should store it in environments of -4° to 113° F. That?s 0° to 35° C
and -20° to 45° C for the metrically inclined. Keeping your iPhone as
near room temperature as possible (72° F or 22° C) is ideal.
Viewing Usage Statistics
Awareness of how you use your iPhone and knowing how long your battery
typically lasts can help you improve its battery life. You can view
your iPhone usage statistics by tapping the Settings icon on the Home
screen and choosing General Usage. Under the ?Time since last full
charge? heading you?ll see two items:
*. Usage: Amount of time iPhone has been awake and in use since the last
full charge. The phone is awake when you?re on a call, using email,
listening to music, browsing the web, or sending and receiving text
messages, or during certain background tasks such as auto-checking email.
*. Standby: Amount of time iPhone has been powered on since its last full
charge, including the time the phone has been asleep.
(Update to the Latest Software)
Always make sure your iPhone has the latest software from Apple, as
engineers may find new ways to optimize battery performance. Using the
latest version of iTunes, you can update your iPhone with the latest
software. Connect your iPhone to your computer, then select iPhone in
the Source List. In the Summary panel, click ?Check for Updates? to see
if there?s a new version of the iPhone software available. Click Update
to install the latest version.
(Optimize Your Settings)
Depending on how they are configured, a few features may decrease your
iPhone battery life. For example, the frequency with which you retrieve
email and the number of email accounts you auto-check can both affect
battery life. The tips below apply to an iPhone running iPhone 3.0 or
later software and may help extend your battery life.
(Minimize use of location services: Applications that actively use )
location services such as Maps may reduce battery life. To disable
location services, go to Settings General Location Services or use
location services only when needed.
Turn off push notifications: Some applications from the App Store use
the Apple Push Notification Service to alert you of new data. Those
applications that extensively rely on push notifications (such as
instant messaging
applications) may impact battery life. To disable push notifications,
go to Settings Notifications and set Notifications to Off. Note that
this does not prevent new data from being received when the application is
opened.
Also, the Notifications setting will not be visible if you do not have
any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to
fetch data wirelessly at specific intervals. The more frequently email
or other data is fetched, the quicker your battery may drain. To fetch
new data manually, from the Home screen choose Settings Mail,
Contacts, Calendars Fetch New Data and tap Manually. To increase the
fetch interval, go to Settings Mail, Contacts, Calendars Fetch New
Data and tap Hourly. Note that this is a global setting and applies to
all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo!,
MobileMe or Microsoft Exchange, turn off push when you don?t need it.
Go to Settings
Mail, Contacts, Calendars Fetch New Data and set Push to Off.
Messages
sent to your push email accounts will now be received on your phone
based on the global Fetch setting rather than as they arrive. If the
global Fetch setting is set to Manually, you will not be able to locate
your iPhone using the MobileMe Find My iPhone feature.
Auto-check fewer email accounts: You can save power by checking fewer
email accounts. This can be accomplished by turning off an email
account or by deleting it. To turn off an account, go to Settings
Mail, Contacts, Calendars, choose an email account, and set Account to
Off. To remove an account, go to Settings Mail, Contacts, Calendars,
choose an email account, and tap Delete Account.
Minimize use of third-party applications: Excessive use of applications
such as games that prevent the screen from dimming or shutting off or
applications that use location services can reduce battery life.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power.
Go to Settings Wi-Fi and set Wi-Fi to Off. Note that if you
frequently use your iPhone to browse the web, battery life may be
improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit,
you can turn off Bluetooth to save power. Go to Settings General
Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone
always tries to maintain a connection with the cellular network, it may
use more power in low- or no-coverage areas. Turning on Airplane Mode
can increase battery life in these situations; however, you will be
unable to make or receive calls. To turn on Airplane Mode, go to
Settings and set Airplane Mode to On.
(Adjust brightness: Dimming the screen is another way to extend battery
life.)
Go to Settings Brightness and drag the slider to the left to lower
the default screen brightness. In addition, turning on Auto-Brightness
allows the screen to adjust its brightness based on current lighting
conditions. Go to Settings Brightness and set Auto-Brightness to On.
(Turn off EQ: Applying an equalizer setting to song playback on your )
iPhone can decrease battery life. To turn EQ off, go to Settings iPod
EQ and tap Off. Note that if you?ve added EQ to songs directly in
iTunes, you?ll need to set EQ on iPhone to Flat in order to have the
same effect as Off because iPhone keeps your iTunes settings intact. Go
to Settings iPod EQ and tap Flat.
Turn off 3G: Using 3G cellular networks loads data faster, but may also
decrease battery life, especially in areas with limited 3G coverage. To
disable 3G, from the Home screen choose Settings General Network
and set Enable 3G to Off. You will still be able to make and receive
calls and access cellular data networks via EDGE or GPRS where available.
(Lock Your iPhone)
It may seem obvious, but you should lock your iPhone when you aren?t
using it. You will be able to receive calls and text messages while it
is locked, but nothing happens if you touch the screen. To lock iPhone,
press the Sleep/Wake button. You can also set the Auto-Lock interval so
your iPhone will turn off more quickly after a period of inactivity. To
set Auto-Lock, go to Settings General Auto-Lock and set the
interval to a short time, such as 1 minute.
(Use iPhone Regularly)
For proper maintenance of a lithium-based battery, it?s important to
keep the electrons in it moving occasionally. Be sure to go through at
least one charge cycle per month (charging the battery to 100% and then
completely running it down).
All battery claims depend on network configuration and many other
factors; actual results will vary. Rechargeable batteries have a
limited number of charge cycles and may eventually need to be replaced
by an Apple service provider. See www.apple.ca/batteries for more
information. For more details of iPhone performance tests for talk
time, standby time, Internet use over 3G, Internet use over Wi-Fi,
video playback, and audio playback, see www.apple.ca/iphone/battery.html.
