This is hilarious. I am about to stop using an iPhone 5 that I bought 2nd hand in favour of a new cheap flip. I spent more time updating the iPhone's OS and charging its battery than I did using it. I am engaged in 2 separate email conversations on the subject. Several people I know are about to do the same.
Btw, I have never used the camera on my iPhone. Even if I think of it, the battery will likely be nearly dead because I forgot to charge it. I used to charge my old flip phone 3-4 times per year, never thought about it. Obviously I am not a heavy phone user, but it kind of annoys me that cheap dumb options are disappearing.
So when I change over to my new flip, I'll have a useful cell phone and what amounts to an iPod.
