Battery research of some sort. please. If an iphone could last just 1 week without a charge and that stayed that way for 5 years. It would sell me over android EASY
I'm not sure selling a phone that lasts 5 years is in the best interest of any phone company. And if it took that much just to sway you and company, then they might as well forgo this segment of the market because there are bigger fishes to fry. Don't get me wrong, the battery capacity will increase linearly but so will the consumption rendering about the same 1 day usage per charge.
