Mark, the iPhones are really very good at battery usage.  More so than the 
equivalent android devices I think having both at my disposal.

I like to do this over weekends where I just let my phone drain from usage.  
It’s the type of thing you do once every month or other month so it’s not 
something you do frequently but it can be tricky to drain them.  Wait until you 
see it sit at 1% for over an hour and still run.:)
