Dropped my iPhone in water. Can I still charge it?

So I recently dropped my IPhone in the toilet, right after it happened I immediately took it out & played with it to see if it would work. I texted my boyfriend after the incident, & he told me to out into rice, on airplane mode, & leave it over night. But there's only one problem. My phones at 10%, & I need it charged for tomorrow. Can I charge it, or is it a bad idea? By the way, after I pulled my phone out of the toilet, I plugged it in to see if the charger still worked, & it was fine. I just need to know if I can still charge it or not.

It's best if you don't attempt to do anything with your phone until it has had time to completely dry out. Turning it on to see if it still works is probably the worst thing you can do.

When phones get soaked, it's the combination of water (which is conductive unless it is absolutely pure), and electricity from the battery that causes any wet internal circuitry to self destruct by electrochemical reaction. The first thing to do when a device gets dunked is to remove the battery if at all possible. Don't attempt to turn it on until everything inside has had plenty of time to completely dry out. You don't want to cause permanent damage to parts of the circuit that may still be wet by sending power to them.

It can often take a week or more if water is trapped under surface mounted circuit board parts unless you take things completely apart.

Forget the "rice advice" you may have heard. That dangerous myth was probably started by someone in the business of selling replacement phones. It is often repeated by those who don't know why it's a really dumb idea, especially if the battery isn't designed to be easily removed. While rice is a mild desiccant and will absorb small amounts of moisture from the air when transferred from a dry to a more humid location, it has absolutely no magical qualities that will quickly suck water out of a phone. A warm location - not the microwave - and a little air flow will be many times more effective. Since your goal is to get everything dry in a reasonable amount of time, it's counterproductive to reduce the air flow to nearly zero and artificially create a humid location by placing everything in a bowl or plastic bag. Besides, you don't really care where the moisture goes once it has evaporated from your phone.
