Water Damage Problem with iPhone 5s. Battery problem?

Ok. I already ordered a new battery. And it should come next monday. Is there anything else I should try? Thanks for the help.

Washing it out with 99% alcohol if there is corrosion the battery might not work

Putting a phone into a bag of rice, especially with a CHARGED BATTERY is going to do absolutely nothing to save a phone. I have disassembled phones that have been in rice for weeks and still found moisture behind the battery and inside the screen assembly flex cables , especially on Apple. I wish people would just do the right thing and quit guessing or spreading myths. It needs to be disconnected from the battery ASAP, as this is what does the damage...plus water mixed with hand goo salt from using it pushed into all the cracks and crevices (ie: SALTWATER)....and it needs to be disassembled and boiled in 91% ISO alcohol....and inspected for damage/corrosion after cleaning. NONE of these are waterproof despite claims, and NOTHING but the above method will dry out water between the sheets of a back light or inside the shielding of a logic board or under the battery with a bag of rice...all they do is a slow meltdown inside as the battery drains through everything...sitting in a bag of rice. Let a Samsung AMOLED dry out in rice, sure...after a couple days they seem to work great, Sammy makes a good phone...except that salt water sits in the loop of the LCD connector where it enters the glass of the LCD...and roasts away the power and ground leading to the screen...and various feeds. Bare copper, not covered about 1,mm wide. Ya know it's happened when on day 3 the crisp image slowly begins to disappear behind a veil of green static... and you are into a $150-$400 repair depending on model. I charge $60 to dry a phone out, plus parts. Usually that's $20 more for a new battery. I almost always give back a none the worse for wear phone provided it wasn't charged or left in a bag of rice for a week Most places charge the same. Money well spent...On a side, NO, I can't help you! By the time it would get to me it would be too late! Support your local reputable phone repair guy/gal...pull the battery, DON'T CHARGE IT (ps, don't light your basement on fire because it's flooded either) and take it IMMEDIATELY to her/him!
