Being water damaged, there's no guarantee that the problem will only be the battery. Chances are it will have a logic board issue. Now depending on the issue, it may harm your battery although realistically, it won't. It's a chance you will have to take. However, before doing anything else, I would decontaminate the logic board. * Open your phone and remove the logic board (follow this [guide|61314|guide]) * Inspect the logic board, especially around the connectors and look for corrosion. * Inspect both sides of the board. Unfortunately, most of the board is covered in shields. That's usually where the damage is occurring. * Put your board in a container with >90% isopropyl alcohol and let it sit for a while. * Use a soft brush, like a toothbrush and lightly brush away any corrosion you see. * Rinse in alcohol and repeat. * Let it air dry for a day. * Re-assemble and hope for the best. If that doesn't work, a professional repair shop that does water damage repair may be able to recover your phone or the data because they have access to pro-level ultrasonic baths and specialized cleaners as well as the skills to troubleshoot your board. Many shops have a no fix/no fee policy so you don't have to spend money to find out if the phone is fixable or not.
