The past couple of days, I noticed a big reduction in my battery. the main culprit was the Android OS. Usually it is the screen.
I didn't notice any updating going on. The only thing I can think of was I was traveling throughout the countryside. So, was it do due searching for a signal (4G vs 3G)? Does that take a lot of energy to do? I would have thought I would have noticed this more being in the suburbs or city where a 4G signal is more likely than rural.
I turned WiFi until needed. Anything else?
Oh, I am in the process of doing another "FoxKat battery enema."
