IPhone 5c battery issues after jailbreak?

So a few months ago I jailbroke my phone, and since then I have experienced really bad batter drain. I will gladly pay the money for a replacement battery if that will solve the problem, but I was wondering if it will.

These are my battery statistics:

Design Capacity: 1500 mAh
Max Capacity: 1400 mAh (this number fluctuates, sometimes going as low as 1350 mAh)

If someone could tell me whether I need to buy a replacement battery or reverse the jailbreak/restore the phone, it'd be greatly appreciated!

If you consider it's due to the jailbreak, you must be using some resource intensive tweaks, try uninstalling some to see if it gets better. Your battery is still pretty good, I'm not sure if it's normal wear for the time you've had it, but batteries do wear out.

You can restore and update your phone if you wish to unjailbreak it. I've had jailbreak since iOS 5 and haven't seen major battery drainage except when I install heavy tweaks like "hello Siri" it other always on the background tweaks.
