Guess I'm finally a yuppie.
iPhone 6 is pretty cool.
I've got one. Don't use 3/4 of what it can do. Some things are neat, but totally useless, like Garage Band, iBooks, Health, Stocks and a few others.
I did download a few apps that I use.
Turn the blue tooth and hot spot off, unless you use it all the time and the battery should last you a couple days.
