OK, most of these things are just pure junk. I know that. I decided to try 'Battery Guru for snapdragon processor' because reading through the reviews it seemed somewhat positive. It scans your usage over 4 days and then "does it's thing"...whatever that is . I have a few hours left of it's initial scan but yesterday I had the best battery-life day ever. I'll let you know if it seems to be working. The problem with these things is it's "seat of the pants" experience and you kinda guess if it is working. Will see. If anyone has any input on it, I'm all ears. Even, or especially if that is negative. I'm a big boy and can handle it.
