Battery is draining fast

@tanishkjangir could be setup related or could be firmware related Always make sure that your setup is using the most power efficient settings.

With that said, you do want to go ahead and replace the battery. Since iFixit does not yet have a specific guide for this, use the one from here It is written in Spanish so use a browser that can translate it for you, if needed. Replacement batteries are readily available at many online stores.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
