Guess what? The problem is about to be fixed with the new update for your iPhone which is not yet decided when its going to be released. But with this update your iPhone would no longer be losing battery all fast. This update would fix the bug inside your iPhone that causes the problem. With this update you don't have to worry about your iPhone losing battery and just enjoy whatever you do on that iPhone. The update was said to be release in a few weeks so we just have to wait a little more longer then we can have the time to enjoy our iPhone.
