While I have a few other blog posts in various stages of completion … understanding how to maximize the batter life seems to have taken on a life of its own. While I don’t have answers at the moment, I wanted to share what I had learned up till this point.

Getting Started

Without getting overly technical, remember that the Android represents a small powerful computer in the palm of your hand. Everything that you do (Screen, Communications, Wi-Fi) all need power. What isn’t as obvious though is that the CPU (for all intents and purposes of this article, the brains of the computer) can place a drain on the battery as well.

Why is this important? Well, the Android allows multiple applications to run at the same time. This means that while something is “running”, the CPU is being used — which in turn can act as a drain on the battery

Tracking Down Those Background Processes

Unfortunately, this next section might get a tad technical for some, but stick with me! Right now, I am trying to get a better understanding of what is running on the background — and ideally determine what can (and can’t) be stopped.

So the next step was to find some tools that could help me identify the list of tasks that were running. While there are a number of free tools available, the one I have started looking at is called TasKiller(yes — it only has 1 K). To get it:

  • Go to the Android Marketplace
  • Do a search for TasKiller
  • Download it (the application is free)

If you run TasKiller, it will give you an indication of the number of things that are loaded into your Androids memory (which in theory could mean they are running and/or putting a load on the CPU). For the record, TasKiller is fairly simple to use — when you see the list of elements, you simply click on tasks to stop them from running.

Other Things I See

The Android also comes with a “Corporate Calendar” application, which the vast majority of people are never going to use. I see this program/task getting loaded as well, and I haven’t quite figured out a way to get rid of it, or how to delete it and/or just disable it. So that’s on the to-do list as well.

More to come on this — but I might share what I have found on power cables next (Hint — don’t buy the Verizon Car charger — there are cheaper ones that are the same or higher quality).
