This is not something due to miscalibration- either you have a defective battery or your phone has suffered damage. You will need to get a new battery or phone.

What model of iPhone, and if it's at half capacity, why not see how much Apple charges for battery service? I want to think it's only $79 - a lot cheaper than an upgrade.

It's an iPhone 5, 32Gb. There's no apple service for where I live.

All batteries by Apple are designed to withstand at least 1000 charge cycles while retaining a 80% or above charge. The percentage is not based off of a different circuit, it is calculated directly through the use of the battery. If you can bring it into an Apple Store or a certified retailer, then they will do a diagnostic, and see if you battery isn't working correctly. iPhone 5 has been notorious for shitty battery, so I wouldn't be surprised. You will be able to get the 5s or the 6's for cheaper as it gets closer to September/October when Apple releases their new phones.
