Battery life very poor

[ike]

Hi Yealink Support,
i have the same problem (newest firmware also).
You wrote "10 hours talk time, 100 hours standby time" in your product sheet.
What battery do you use?
What minimal hours are ok and not guarantee? (e.g. 9 hours talk, 90 hours standby time is ok? or 8 hours/80 hours or....?)

Btw.:

"then enter the webpage, find the pcap feature, click Start ,and reproduce the issue, then click Stop, and export the pcap, syslog, config.bin to us."
What should i do?:
1. press Start
2. reproduce the issue - Battery run's low
3. press Stop (after Minutes / Hours)?!

Thank you
