I have a s8 and it recently went under water in a pool. The next day the it would not charge pass 12% even when turned off and was getting hot and then the battery would drain. I tried got to like 40% and it drained within minutes. I changed the battery but there wasnt much improvement. I factory reset and cleared the cache.
The phone still is getting hot and giving problems to charge as i have to unplug it when it gets hot and resume charging when it cools. I managed to get it charged to 100% while turned off. When i turned it on the phone dropped to 24% within 2 and a 1/2 hours with very minimal usage and didnt get as hot . Placed it to charged it reached 36% and started to drain as it got hot. So i unplugged it and placed it aside
The LCI within the sim tray still remains as before and hasn’t changed to indicate water damage.
Now i am lost as to what i should do. Can amyone help??

I was having similar issues with my Galaxy S5, but not because I dropped it in water.
It started when my phone got really hot using a car charger while navigating causing the phone to shut off. Since then, I was having problems with my Samsung Galaxy S5 phone randomly locking up, shutting off or restarting for months I tried all the recommended solutions – phone reset, clearing cash, removing apps, and a new OEM battery. Nothing worked to fix it. I was beginning to think that some event had corrupted the battery management system in the phone either by overheating, malicious downloads, or software upgrades from Samsung or AT&T. One day I was pulling the battery to fix the phone from a system lock up and I noticed that the battery contacts were dull with a thin oxidation layer. Gold plated contacts should be shiny from my experience with electronics. Therefore, I used a cotton swab and applied some WD-40. Well that worked for about a week before the WD-40 dried up and the oxidation came through the poor quality thin gold plating again. After doing this for over a month I was feed up and ordered another battery but this time instead of getting a Samsung OEM battery, I purchased a Acevan 3600 mAh battery. Problem solved, the phone has been good for four months now without a single issue. In conclusion, Samsung has cheaped out on the quality of the replacement batteries to save a dime or force you to upgrade your phone, therefore it could be affecting more than just the phone model I have.
