I first heard of the advocate said that some time ago. If users Andrews version guyed Launch the application and hold may rest Battle 75 - 80%., But if the OS you will be battery about 94 - 95% I disagree, of course. . Because you do not have a reference that you mentioned come from?, Reliable or not, you may have to speak up without thinking. I would like to talk about the advantages of an Android OS on the iPhone. It is not about price. Because, since the price of 2000 baht or more, depending on demand, we can purchase it. Unlike Apple's iOS, priced at 15,000 baht or more. Although the capacity to choose to suit their needs, but the price is still very high anyway. Thus, people who use just checking email and browsing the web. Probably is not worth the price of purchase. Anyway, the idea I think. The Android OS is definitely better than me.
