I had recently dropped my phone in the toilet.. It still works.. except when I put it on the charger it doesn't say it's charging. Yet, the percentage goes up every 5 or so minutes. Throughout the night while on the charger it will go up to no more than 30 percent. Is it my battery thats messed up? But with my battery case it charges normally. (Phone case that charges your phone.) And its not the charger thats messed up, I've tried many chargers. Is there any way to fix this problem?
