I dropped my iphone 5 in water what should I do?

I dropped my iPhone 5 in water for maybe 3-5 seconds. I got it out and took the case off immediately. I got all the water off the front back and sides. I got a q-tip and got as much water as possible out of the audio input and the charger port. I didn't turn it off though my power button is broken (not from this) and if I turned it off the only way I could turn it back on is to plug the charger in which if it's been in water could possibly do more damage. It's been sitting for about an hour and its still on and working. All the buttons work volume the switch for vibrate and ring the home button and the screen still works. Is there anything else I should do?

Since it works (which is obviously good news), just for safety measures leave it in a bag of rice overnight, it should absorb the leftover moisture in your phone!

Put it in a bowl of rice for the night. It should soak most of the water up.

Put it in rice.

You better get the moisture off what you do is get zip plastic bag put it inside and put as much rice as possible zip the plastic so that air won't get out leave it for a while so that the rice will absorb the moisture.

Well silicon pellets work the best. The little packets in electrical products you buy have them. Just put the phone in a plastic with an open packet package of silicon. If you do not have silicon then place in sealed bag or container of rice.
