First of all, what are the common complaints with android smartphone devices? Issues such as: system halted; application crashes; slow booting; and, battery life.

A year ago, I purchased my first android phone and installed CM ROM. Within months, I became very
annoyed that my battery did not last the entire day. I could go to bed, with a full battery charge, and awake in the morning to find that the battery charge had dropped significantly overnight. I found this situation to be unacceptable! To solve this, I downloaded power-saving applications.

Every day I would install a different power saving application, charge the battery to full power before bed, and then check the battery in the morning. After a month of testing power saving applications, I
didn't find a satisfactory solution and some of the so-called power saving apps even made the battery drain faster. So, I thought I would create an app for myself, that could tweak system parameters and help save my battery. Nine months ago, I started writing a power tweaking application for myself. I studied the intracies of the android power management mechanism and within a few months I had the basis for an application that could optimize my power management. Everyday, I tweaked the power optimization parameters and tested each night. One morning, I awoke and was thrilled to discover that the battery charge had only decreased by a small amount. So, I turned my personal power saving tweaker into a user-friendly power saving application that anyone could use. I am sharing my application, One Power Guard with you.
