Charging
Charge iPhone with the included USB cable and power adapter, or with other third-
party “Made for iPhone” cables and power adapters that are compatible with USB 2.0 or later,
or power adapters compliant with applicable country regulations and with one or more of the
following standards: EN 301489-34, IEC 62684, YD/T 1591-2009, CNS 15285, ITU L.1000, or another
applicable mobile phone power adapter interoperability standard. An iPhone Micro USB Adapter
(available separately in some areas) or other adapter may be needed to connect iPhone to some
compatible power adapters. Only micro USB power adapters in certain regions that comply
with applicable mobile device power adapter interoperability standards are compatible. Please
contact the power adapter manufacturer to find out if your micro USB power adapter complies
with these standards.
Using damaged cables or chargers, or charging when moisture is present, can cause fire, electric
shock, injury, or damage to iPhone or other property. When you use the Apple USB Power
Adapter to charge iPhone, make sure the USB cable is fully inserted into the power adapter
before you plug the adapter into a power outlet.
Lightning cable and connector
Avoid prolonged skin contact with the connector when the
Lightning to USB Cable is plugged into a power source because it may cause discomfort or
injury. Situations such as sleeping or sitting on the Lightning connector should be avoided.
Prolonged heat exposure
iPhone and its power adapter comply with applicable surface
temperature standards and limits. However, even within these limits, sustained contact with
warm surfaces for long periods of time may cause discomfort or injury. Use common sense
to avoid situations where your skin is in contact with a device or its power adapter when it’s
operating or plugged into a power source for long periods of time. For example, don’t sleep on a
device or power adapter, or place them under a blanket, pillow, or your body, when it’s plugged
into a power source. It’s important to keep iPhone and its power adapter in a well-ventilated
area when in use or charging. Take special care if you have a physical condition that affects your
ability to detect heat against the body.
Hearing loss
Listening to sound at high volumes may damage your hearing. Background noise,
as well as continued exposure to high volume levels, can make sounds seem quieter than they
actually are. Turn on audio playback and check the volume before inserting anything in your ear.
For more information about hearing loss, see
www.apple.com/sound
. For information about how
to set a maximum volume limit on iPhone, see
on page 73.
To avoid hearing damage, use only compatible receivers, earbuds, headphones, speakerphones,
or earpieces with iPhone. The headsets sold with iPhone 4s or later in China (identifiable by
dark insulating rings on the plug) are designed to comply with Chinese standards and are only
compatible with iPhone 4s or later, iPad 2 or later, and iPod touch 5th generation.
WARNING:
To prevent possible hearing damage, do not listen at high volume levels for
long periods.
Radio frequency exposure
iPhone uses radio signals to connect to wireless networks. For
information about radio frequency (RF) energy resulting from radio signals and steps you
can take to minimize exposure, see Settings > General > About > Legal > RF Exposure or visit
