Mobile Device Charging
Your Cisco IP phone keeps charging the mobile device while in power saving mode but stops charging in
deep sleep mode.
The USB charging feature supports the following mobile devices:
• Apple
• Samsung
Other mobile devices are supported but there may be instances of incompatibility where they will not get
Note
charged.
When charging your mobile device using your Cisco IP Phone, the following conditions apply:
• When you plug in a tablet, it takes about 3 seconds for the charging to begin. When it gets fully charged
or nearly fully charged, the charging icon does not display and the battery capacity may decrease over
time.
Note
• In the PoE mode, when you plug-in a tablet, it does not display the charging icon and the battery capacity
may decrease over time.
• If the battery capacity of your mobile device is lower than 90% when you plug it in, you will notice that
charging starts immediately, stops for 2 seconds, and then resumes.
• If you unplug your tablet and immediately plug-in a USB headset to the tablet, there will be a delay of
3 seconds before the phone recognizes the USB headset.
• When more than one Cisco IP Phone 8800 Key Expansion Module is attached, the back USB port cannot
fast-charge the device.
