The battery consumption is very subjective. When I updated the firmware my idle consumption drop from 18mA to 8mA. I was delighted. And then I decided to do a battery calibration by a full charge dischage cycle. Now my average idle current has gone up to 43mA or about 3% per hour which is rather high. I did not change the phone setting at all. By the way my defination of idle is internet off , 3G(four bars) with all notifications or sync off. No application running except the settings app.
