Why is my iphone 5 battery keeps going down?

I tried everything. From resetting, closing all apps, and brightness. Is there something wrong?

  • Why is my Iphone battery going down while being charged? Well just last night I charged my Iphone 4 All night and woke up to it being at 28% .

Could it just be my charger or my actual phone? If it was the charger I would think it wouldn't show the lightning symbol but it does. What wrong with it.
