Question S4 landed in toilet, works but battery charging issues

Hi guys,

A few months ago my S4 was kindly placed in the toilet by some children. It was dried out in rice, and does work OK but only one weird thing happens... when I charge it when switched off it never hits the 100% charge, it hit's the line of the main battery icon but not the nipple top section. If I then switch the phone on it shows that it's about 97% and if I leave it on charge a few minutes later it hit's 100%.

I even purchased a new official Samsung battery for it and the same problem arrises. I've flashed the latest ROM via Odin etc, still the same.

Any ideas please?

All the best and have a happy new year
Current: Samsung Galaxy S 4 (i9505)
