Caution

To ensure that the phone does not get water into the battery compartment, make sure that the compartment is tightly closed. See Install the Cisco Wireless IP Phone 8821 Battery.

If the sound is muffled after you dry the phone, there may still be water in the microphone or speaker compartments. Place your phone, speaker-side down, on a dry, lint-free cloth to see if water drips out. If there is still water in the phone, allow the phone to completely dry before you use it.

Best Practices for Battery Power Conservation

The Cisco Wireless IP Phone 8821 and 8821-EX has a 2060-mAh smart battery. The battery capacity is reduced to 80% after 500 full charging cycles (charging from empty to full). The battery life also depends on the phone state, the frequency and AP scanning configuration.


Caution

The expected lifecycle for a battery is two years. Based on the average usage, this corresponds to approximately 500 charges. You can check the date printed on the battery to calculate the age of the battery. We recommend you to replace the battery when it reaches its end of life.

Note

Low battery warnings appear onscreen when the battery reaches these set charge levels: 10% and 3414mV (~2%). If users don’t charge or replace the battery after the last warning, the phone automatically powers down after 1 minute. You can’t change or disable these low battery warning levels. For more information about the warnings, see the Cisco Wireless IP Phone 8821 and 8821-EX User Guide.

For more information on batteries, see:

  • Cisco Wireless IP Phone 882x Series Accessory Guide

  • Cisco Wireless IP Phone 8821 and 8821-EX Wireless LAN Deployment Guide

  • Cisco Wireless IP Phone 8821 Battery Performance

Follow these best practices to ensure that the phone conserves battery power.

User Actions

Remind your users that the battery life is reduced when the phone is turned on. Calls, messages, application use, Bluetooth use, and actions like menu navigation use power.

Users should ensure that the phone remains in a good RF coverage area and that the phone can maintain a constant connection to the Cisco Unified Communications Manager. If the phone moves out of range and remains out of range for a significant time, battery life can be reduced.

For more information about RF coverage, see Cisco Wireless IP Phone 882x Deployment Guide.

Phone Configuration

Configure the Scan mode field in Cisco Unified Communications Manager to suit your enterprise. The phone supports Continuous, Auto, and Single AP scanning, where Continuous is the default. The configured scan mode determines the battery life baseline.

  • Continuous scan mode is designed for phone users that are constantly on the move and for whom frequent roaming events occur. This mode maximizes performance and connectivity, but at the expense of battery power.

  • Auto scan mode is designed for phone users that only roam occasionally, and whoe require more idle battery life than Continuous scan mode can offer.

  • Single AP scan mode is designed for phone users that do not roam and require maximum idle battery life.

Access Point Configuration

  • For optimal idle battery life, we recommend that you use an access point that supports the Cisco Compatible Extensions (CCX) Proxy ARP feature. CCX Proxy ARP allows the phone to remain in suspend mode longer instead of waking up at each DTIM period. This reduces power consumption.

    The Cisco Lightweight Access Points and Cisco Autonomous Access Points support CCX Proxy ARP, but Cisco Meraki Access Points do not.

    For Cisco Lightweight Access Points, CCX Proxy ARP is enabled by default and nonconfigurable. For Cisco Autonomous Access Points, CCX Proxy ARP is disabled by default, but can be enabled with the dot11 arp-cache optional command.

    If the access point does not support CCX Proxy ARP, then the phone must wake up at each DTIM period. Frequent wakeups can reduce the idle battery life by as much as 50%.

  • We recommend that you use an access point that supports the Cisco Compatible Extensions (CCX) Dynamic Transmit Power Control (DTPC) feature. When DTPC is enabled, the access point advertises its transmit power to all clients. The phone adjusts its transmit power to the minimum level necessary to communicate with the access point. A lower transmit power reduces unnecessary noise in other areas.

  • Limit the use of multicast. If the phone subscribes to a multicast stream, it wakes up at each DTIM period to receive multicast frames. Frequent wake-ups cause power consumption to increase.

  • Select an access point that supports U-APSD. This power save protocol is used when on call and when idle.

    • The On Call Power Save field in the Wi-Fi Profile should remain enabled so that the phone can use U-APSD.

    • If the On Call Power Save field is disabled, then the phone uses active mode when on call, but uses U-APSD when in idle mode.

    Only disable On Call Power Save for troubleshooting purposes.

Phone Firmware

The factory installs a version of the phone firmware on the phone during manufacturing. But that firmware may not be the latest firmware version.

Your Cisco Unified Communications Manager stores the firmware loads. If the version of firmware on the phone is not the latest version, the Cisco Unified Communications Manager sends the updated firmware load to the phone.

Device Packs

The Cisco Unified Communication Manager Device Pack contains device configuration capabilities for the phones. Many phone features require the latest device package to be installed on the Cisco Unified Communications Manager. If you do not install the device pack, the new phone features do not work.

A device pack introduces new phone types to Cisco Unified Communication Manager. The pack installs the firmware and the configuration files needed to enable features on your phone. New features may be turned off by default and they have attributes or settings that must be configured.

To find which device packs are available for your Cisco Unified Communications Manager version and phone, go to http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/devpack_comp_mtx.html

Phone Configuration Files

Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications Manager that requires the phone to be reset, a change is automatically made to the phone configuration file.

Configuration files also contain information about which image load the phone should be running. If this image load differs from the one currently loaded on a phone, the phone contacts the TFTP server to request the required load files.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For more information, see the documentation for your particular Cisco Unified Communications Manager release. A phone requests a configuration file whenever it resets and registers with Cisco Unified Communications Manager.

A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when the following conditions exist:

  • You have enabled autoregistration in Cisco Unified Communications Manager

  • The phone has not been added to the Cisco Unified Communications Manager database

  • The phone is registering for the first time

Related Documentation

Use the following sections to obtain related information.

Cisco Unified Communications Manager Documentation

See the Cisco Unified Communications Manager Documentation Guide and other publications that are specific to your Cisco Unified Communications Manager release on the product support page.

Cisco Unified Communications Manager Express Documentation

See the publications that are specific to your language, phone model, and release on the product support page for Cisco Unified Communications Manager Express.

Cisco IP Phone User Support

If you are a system administrator, you are likely the primary source of information for Cisco IP Phone users in your network or company. It is important to provide current and thorough information to end users.

To successfully use some of the features on the Cisco IP Phone (including Services and voice message system options), users must receive information from you or from your network team or must be able to contact you for assistance. Make sure to provide users with the names of people to contact for assistance and with instructions for contacting those people.

We recommend that you create a web page on your internal support site that provides end users with important information about their Cisco IP Phones.

Consider including the following types of information on this site:

  • User guides for all Cisco IP Phone models that you support

  • Information on how to access the Cisco Unified Communications Self Care Portal

  • List of features supported

  • User guide or quick reference for your voicemail system
