My iPhone keeps dying with 20% battery. What should I do?

I have an iPhone 5 and recently it has been dying with like 20% battery or it will start dropping insanely fast when it get below 40%
Today it died with 40%
It has died before because it got too cold but that's not what it is this time. Or it shouldn't be be.

Flashing Apple Logo on iPhone 4?

Recently, I've updated my iphone 4 which was jailbroken to the new iOS 7, and then it started flashing the apple logo for probably two hours or even more, so i let the battery die out overnight, the next day I plugged it back into my computer and it had the charging bar for a couple of seconds, but after that the flashing started again, then i tried to turn it off and recover it, i held the lock and home button as it says on the applesupport website, but now it won't even turn on, it's not flashing, but even though it's connected to my computer, my itunes doesn't read it nor does it even turn on.
