I want to know how does applications that are installed in Android or iPhone eats up phone battery. I had performed test with both. My friend has a iPhone and I have a Android phone. First we tested the battery life without adding any new stuff which worked nicely. The phone was working for entire day without giving a low battery warning. Then we installed some application like games, social networking apps, location apps, live wallpapers, etc. We played them once and then stopped it. The applications were closed but still the phone's battery performance reduces to half.
Does this application still works even when we are not using them. I though that the phone will atleast give me 6 hrs of constant battery life under every condition. This is far more poor performance that I had not expected.
