If an iPhone is jailbroken, there's an app called BatteryInfo Lite which can display hefty amount of stats, including battery cycle count 🙂
Yes your correct and this peice of software is actually pritty accurate and works well.
but as wjosten says the apple store is always the best option as they know what they are doing!
There's an app called 'iBackupBot' for windown and mac, by a company called iCopyBot. It has a free trial and allows you to measure the current battery capacity, they have a guide here.
It worked for me with an iPhone 5, iOS 6.1.4- you do have to quit itunes and unlock the device for it to work.
