I've gotta say that's pretty sharp looking and doesn't appear to add much bulk at all.
So how exactly do this battery case operate? From vaguely reading these types of threads over the years, it seems like it goes like this:
The iPhone drains, then when it drains, the case recharges the iPhone.
Correct?
I want a battery case that isn't just a "mobile recharge source", but sort of permanently supplements the internal battery. Rather than "essentially" doubling the battery life by allowing you to recharge, I want the external battery to work WITH the internal battery to actually double battery life (or at least on the user end appear to - i.e., I don't want to have to "recharge" with the battery pack, I want the battery pack to act as a larger battery).
Is this even possible?
