There is no need to be calling defenseless phones hateful names. ;-)
For some, having a single extended battery is preferable to having to remember to keep a spare battery charged, or having to grab it on the way out ...or remember to unload it so it doesn't go through the laundry.
There are some who simply do not want to have to open/change out battery/restart phone in the middle of something. Others still are trying to squeeze every bit of use from their phone while away from an outlet, and may opt for an extended battery ....and carry a spare extended battery!
It's a personal preference. Please don't disparage those who choose a different path.
