Battery not working in W52
I have 5 W52 handsets with their own bases. They do not hold a charge for more than about 45 minutes at a time - after having spent the night on their bases. We've had the phones less than a year.
How can this be resolved? We loose customers mid-call because he phones drop the charge.
Thank you for your guidance.

RE: Battery not working in W52
Dear MJ,

Please note that the battery issue has been fixed with our V73 firmware. Please firstly upgrad them to the latest and test again:

Guide for upgrade: http://www.yealink.com/Upload/W52P/20131...rmware.zip

Please kindly let me know the result.
