I have been seeing lots of "My battery only lasted 2 minutes with light usage" or "it last 3 days with heavy usage". I wanted to see if we can get a little more scientific then "light" and "heavy" usage since that is very opinion based. The Incredible has all the information by default that is needed. It can tell you the time the phone has be on, the time it has been awake (doing something not just sitting there), and the battery percentage remaining. Test procedure: See below This should give us all a good idea of how long the battery will last with varies usage percentages. After I have enough data points, I'll try to make some fancy (maybe) chart. I will ask people to wait two days before preforming and posting test data. This will give the community 48 hours to suggest improvements to the test procedures or find errors in it (So trying running through it in case I missed a step). After that, I will not update the procedures to make sure all the test are the same. Let me know suggestions or comments. I think this will be a helpful data and an easy test to do. This is my first Android phone so any suggestions are welcome. Thanks.
