I had the same problem. There are things you can do to prevent the rapid battery drainage (which you can research: how to prevent battery drainage) but you are probably going to need to do a battery replacement. So I recently had my battery replaced at Apple Doctor and I noticed the battery kept draining quickly even after the battery had been replaced. I called the technician that had worked on the phone and told him that the battery was still draining way too quickly he suggested that I let the phone drain to 0% and then put the phone on charge for 4 hours if it is still getting depleted too quickly then it is a problem on the main DV board and that can’t be fixed unfortunately. After I did that and did a hard reset the battery seems to be working fine again. It is also worth mentioning that the technician also told me once your phone’s overall charge capacity drops below 80% your battery definitely needs to be replaced. i’m no professional but I hope this helps.
