So, these days, we seem to be solving the problem of woeful phone battery life by making people carry an extra "turbo charger" or backup battery around with them, to boost the battery when we're away from power and still need our phone to work for, oh, 8 hours at a time.
Can we just take a moment to appreciate the way market demands have completely screwed us over here? I mean, if we weren't demanding that our phone batteries get a couple of millimetres thinner every year, they could actually work long enough for our phones to last an entire day.
Honestly, when you hear that your phone comes with a big brick of a backup battery for on-the-go charging, your response should not be positive. You should be thinking about why the internal battery sucks so hard.

PS - Market pressure being what it is, though, this is the market solution.
PPS - Personally, I'd rather have a battery that doesn't suck.
