Water damage to your cell phone can cause many complications, including loss of data and a destroyed battery. Whether your phone was rained on or submerged in a lake, it's important that you take action as quickly as possible. The longer water sits in your phone, the less likely you are to save it.
Strip Your Phone
Strip your phone of all removable items, including a cell phone case, SIM card and battery. These items will only hold water against your device and prevent it from drying out. As well, using a wet cell phone or trying to turn one on can cause the device to short circuit, so removing the battery allows you to cut all power to it. Don’t worry too much about water on your SIM card; just dry it with a cloth. As long as it hasn't been sitting in water for an extended period of time, it should be fine.
Don't Use Heat
Although heat might seem like the best option for drying your phone, it's best to avoid it at all costs. Hair dryers, ovens and even hot sun cause components within the phone to warp and adhesives to melt.
Dry Your Phone
There are several tactics you can use to dry your phone. One involves holding the suction of a vacuum as close to your phone as possible without touching your phone with the vacuum. This will help pull the water out but you'll need to be patient. It will take at least 15 minutes for this to work. Another option is to use a can of compressed air to blow on the seams of your phone. The idea is to blow the water out of your device. Perform these actions on the battery as well, but focus on the phone first.
Remove Moisture Remnants
Once you have done all you can to dry your phone, place it in a bowl of uncooked rice, along with the battery, for 24 hours. Rice is very absorbent and works the same way as silica packets that are placed in new shoes and purses to draw out moisture.
Test Your Phone
Put your phone back together and turn it on. If it doesn’t work, plug it in without the battery. If you're able to get power to your phone this way, your battery is damaged and you need to buy a new one. If it still won’t turn on, it's time to contact the company that made your phone. Water damage is rarely covered in a warranty, so any repairs will likely be coming out of your own pocket.
