I use the app Badass Battery Monitor to check my battery usage. I've been checking for a while which apps might be using up my battery, but it all seems normal. The only thing that seems abnormal is the amount of battery my phone's kernel uses up. The app says the kernel is taking anywhere from about 25%-35%. Is this range too high? The screen's usage is usually only at about 20-30%. I keep 4g data on and not 3g. I don't know why the kernel is taking up this much battery. Nor do I fully understand what a kernel is, but I feel that it shouldn't consume that much battery.
