Hi all

Since 2 weeks we have 10 8821 Cisco IP Phones in use. On every Phones we have a poor Battery Standby Time. According the Data sheet we should have a Standby Time about 200 hours.

 

The Battery on our Phones is over one night empty.

Cisco IP Phone 8821 Load: sip8821.11-0-3SR4-3
 
Bluetooth is Off
802.11 mode is 5GHz only
On call power save is Enabled
Display sleep is 30 Seconds

Thanks in advance for any suggestions
