hey macrumors! to anyone with the e13ctron hybrid case: has anyone experienced unusual battery drainage? i went from 99% at the beginning of work to 50% once i finished my shift (10am - 7pm. approx. 9 hours). my phone was idle most of the time. i've never experienced such battery drainage with my old belkin case or even caseless. any ideas? could it be because my 3G and 2G signals keep interchanging back and forth? i have also noticed that my data speed has reduced to an all time slow.
