The diagnosis held by an iPhone app developer proves that iPhone is suffering from a chronic software problem. This test methodically proves that the much complained about battery problems are software based rather then hardware. Phew! a sigh of relief, well at least it can be cured rather then changing the over all hardware specs.
Two iPhone devices were tested independently. Both having the same hardware, iOS ver. 5.0.1. Their model and release date was similar. They were even bought from the same location and also using the same network (AT&T). Just to make sure all other differences are avoided to check for their battery performances avoiding hardware differences. The two phones however had different iPhone apps. stored. One was using beta applications to test while the other was a regular use iPhone with out any unorthodox applications.
