My battery does not last for long

@kazibwebaker always check your settings and make sure that you have no apps running in the background, turn you push notifications off too.

If you feel that even with all battery save options on, it still does not last long, it may be time to replace the battery. Since ifixit does not yet have a guide for this, use the one from here Replacement batteries are readily available on 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 the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
