Battery dies at 17%?

[Honza]

Multiple times I have had my iPhone shut itself off due to low battery at percentages above 5%. Today it happened at 17% - either iOS BLOWS at calculating battery percentage, or there's something wrong. I have not been performing intensive tasks when the battery dies, i.e. mostly due to texting, etc. As a side note, my iPad mini often goes down to 1% without dying.

Anybody else frustrated by this iPhone issue? Or do I have a problem with my battery?

Mine does at 20%...

Also had other issues such as battery going from 44-17% in minutes, charging from 10%-32% instantly, and other erratic behavior.

Took it in to an Apple Store and they showed me the diagnostic saying that my battery is in the red area and should be replaced. I guess it's not due to ios7, though that's when I noticed it. As I'm out of warranty, I'll use the extended warranty from my credit card to pay for the battery.

From 44 to 17% in minutes, strange behavior while charging, your battery was clearly defective .... This time is not iOS 7's fault
