Dwhat_to_test.jd52 Mobile devices primarily run on battery power. A device has finite "battery budget", and when it
54 minimize battery usage, you need to test its battery performance, and you need to test the
55 methods that manage battery usage.
58 Techniques for minimizing battery usage were presented at the 2010 Google I/O conference in the
61 Coding for Life -- Battery Life, That Is</a>. This presentation describes the impact on battery
63 impacts. When you code your application to reduce battery usage, you also write the
75 since WiFi transfers maximize battery usage compared to transfers over 3G or EDGE.
