Of course I am the masses! Most people can get through the day with their iPhone. You think people would still buy an iPhone if the majority have a dead battery before they get home? Or are forced to go sit in their car and charge it up? Really? You're going to argue that?
You also fail to understand my argument. Do I want more battery life? Sure! Do I want a thicker, and (more importantly)- heavier phone? No thanks, unless it is a physically larger phone. 10 hours of continual use is enough for me. Your 5000 iPhone people- I assure you- the majority are looking at Facebook, Instagram, and doing non-work activities. Care to argue that? I'd love to hear what all 5,000 people in your office are supposed to be using their phones for where they legitimately don't have enough battery life. It sure as hell isn't simply talking.
And a brick? Hardly. If its such a huge deal- all they need is a lightning cord and a USB plug. Ya'll haven't dropped desktops yet, right?
I do not want to argue that our employs occationally do other things with their phone than work, and so what; the phone is actually made for it, and were I live we pay tax for being fortunate to have a company phone so we never have to leave work. I actually do myself occasionally, like when I spent hours upon hours on various airports recently, checked into a hotel at 5 am and was picked up 2 hours later for a full day of meetings, the entire trip not able to reach an outlet, and not bringing my laptop because this was one of the countries in the world where our security people does not allow us to bring a laptop (or more specifically a harddisk). Guess what? The iPhone died, and what saved the day was the old dumb-phone I also brought, and the fact that I had old-fashioned paper boarding passes for my return.
To me and many of my colleagues, the time battery life in dumb-phones increased to the point that it was no longer a disaster to forget the charger is a time we fondly remember, and some of us, but correctly as you say not all, would gladly carry a few more grams to relive that time, even in the time of USB.
