Seriously? I do not understand this logic. Having to plug my phone in and wait 10 mins for it to allow me to turn it on is a pain. Running out of power in the middle of the day is a pain.
Forgetting to plug it in overnight and having no power for the day is a pain.
The <1 minute it takes me to swap the battery, even with the pretty primitive mechanism in the S4, is a total breeze.
I don't even bother plugging my phone in at night anymore really - because I know in the morning I can swap batteries and be out the door with full power.
