What to do when your phone gets wet

Here are some tips to follow in case your phone ends up in water:


Steps
Take your phone out of the water as soon as possible unless it’s plugged in. The longer your phone’s in water, the more damage it will sustain.
If your phone is plugged into a wall charger and submerged in water, turn off power to the outlet before attempting to remove it from the water.
Turn your phone off immediately, even if it seems to be working. Leaving it on can cause it to short circuit. If it’s been in water, assume it is waterlogged whether it is still working or not. Don’t turn on your phone to see if it’s working.
Remove your phone’s battery and cover and place them on paper towels. This is one of the most important steps to saving your phone. Many circuits inside the phone will survive submersion in water if they’re not attached to a power source (battery) when wet.
Detach any accessories that may be on your phone. Remove any protective covers, ear buds, memory cards, or other things that attach to your phone.
Put your phone in a bowl of uncooked instant rice for 48-72 hours. Pour 4 cups (900 g) of rice into a large bowl. Then bury your phone and its disconnected battery in the rice. The rice will help draw out any residual moisture in your device. Regular uncooked white or brown rice isn’t as absorbent as instant rice and won’t work as well. Rotate the phone to a different position every hour until you go to sleep. This will allow any water left inside to run down and hopefully find an opening to escape through. Be careful when putting phones in rice, since the grains can get stuck in the charging/headphone ports.
Use silica gel packets instead of instant rice if you have some.
Silica gel packets are those little packets that come with new shoes, purses, noodle packets, and other products. Place the silica gel packet(s), your phone, and the disconnected battery into a container. Then let the phone sit for 48-72 hours to give the gel time to absorb any moisture remaining in your phone. There’s no need to open the packets. Simply place them in the container with your phone.
Suck the water out of your phone with a vacuum cleaner.
This is the fastest method and can completely dry out your phone and get it working in 30 minutes. However, unless the exposure to water was extremely short, don’t attempt to turn your phone on this soon. Fit a hose attachment onto your vacuum cleaner. Then, set it to its highest setting and vacuum near all your phone’s openings.
Wait 48-72 hours, then turn on your phone. Before turning on your phone, check to see that it’s clean and looks dry. Wipe away or vacuum any dust and dirt from the device and the detached battery. Then, insert the battery into the phone and try to power it on. The longer you wait to turn on your phone, the more likely it is to survive.
