Not sure exactly but I'm sure someone else will follow up with exact time but I know it lasts several hours

I think it has a battery of 1500mah, which is about 1day of stand-by, and 2,3 hours of talk.

It's been good for around 4-5 hours of talk. As for standby time, Amazon lists the WF721 as having 36 hours battery standby time and 3.5 hours of talk. I presume that the 36 is fairly accurate.

eh, from the manual of the ZTE721 http://www.ztedevices.ca/media/wysiwyg/WF721%20User%20Guide_En.pdf
It said the battery is 1900mah, 25hours of standby, 2.5-3 of 3G talks

There were apparently some shipped without a battery from the manufacturer due to a battery shortage. Not sure if it was fully resolved.
