Sorry if they've been answered. I browsed prior to buying the phone and have yet to see anything on these issues. 1) How do I check the battery level while the phone is off and plugged in? Will the battery indicator on top stay lit up when it's 100%? 2) Why does "Android System" take up so much of my battery? After a full days use, it had 38% used by itself, that concerned me some because I couldn't figure out why. All I can think of for now. Thanks, Harness.
