Battery life very poor

[Yealink Support]

Hi Charliestot，

I am sorry about this issue. I want to share some tips with you.
1. The battery will be red and flash after upgraded. So i advise you to charge them fullly after upgraded.
2. The battery need to be charged fullly about 5~6 hours.

If you do follow my tips and the issue happens again, please describe the steps for me and supply syslog level 6, config.bin and pcap to me.
1. Before you export the syslog, please set syslog level as 6, and reboot the phone
2. 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.
(About where to export these files, please refer to attached screenshots.)

These three files are very important to us, hope you can kindly understand.
