The iPhone 4 smartphones were a different story in water. It appeared that water had been trapped around and under the battery and under various pieces of electronic shielding. The water sensors near the top of the phone close to the earpiece were still bright white when we opened it up. But it was dead nonetheless. Close inspection of the dead iPhone 4s revealed corrosion around the battery connector and swelling of the battery.
A replacement battery fixed one of the dead iPhone 4s. The second dead iPhone 4 was at least able to sync once it got a new battery, but never fully revived. We were impressed by the resiliency of the Galaxy smartphones. The removable battery probably contributed to the improved drying and higher survival rate.
The iPhones were a disappointment in water. The lack of a removable battery is a minor annoyance under most circumstances, but in this case it proved to be the primary point of failure for two of the iPhone 4s. The compact nature of the iPhone may also have inhibited draining.
We tested six common household materials to see which could absorb the most water from a wet sponge in 24 hours:. Dry, uncooked conventional rice was the worst of the seven options we tested. It absorbed the least water in 24 hours, losing out to silica gel, cat litter, couscous, instant oatmeal, classic oatmeal and instant rice.
We know it's tempting, but resist the urge to power up your phone to see if it works—just turning it on can short out the circuits. Water could have gotten into this tiny opening, and you don't want to risk having to replace your SIM, too. Even if your phone turns out to be beyond repair, the SIM should retain a lot of its onboard data, like the contacts in your phone book. Next, dry your phone off. This sounds like the simplest step, but it's actually where things get tricky.
Don't even think about taking a hair dryer to your handset. Added heat could cause corrosion if there's any water on your phone's hardware. That means no microwave, either. You're only going to catch your phone on fire, which certainly will make it dry, but not very operational. While heat will certainly evaporate the moisture, it could also warp components and melt adhesives.
Alcohol is a solvent and can dissolve the internal adhesives. Instead, start with a soft, microfiber cloth, the kind you use to wipe smudges off of your glasses.
If you can remove the back panel of your phone, use a cloth to wipe down the components inside. And if you want some warmth to help coax out whatever water has not yet dissipated, let your phone rest on a windowsill in some sunlight. You can almost imagine our ancestors dunking their precious, soggy goods into burlap sacks of rice long ago.
But where did the rice trick come from — and does it really work? In July , less than a month after the first iPhone was released, a MacRumors forum member by the name of jorsuss launched a thread called "I dropped my iPhone in water" with a familiar tale: "I was checking the phone if I got any calls or messages and I dropped it in the sink. One month earlier, in June , a Washington Post reporter dropped his BlackBerry into a toilet while prepping for a date.
When he saved his phone and his date using the rice trick, it merited a personal account in the paper along with a write-up on LifeHacker: " Dry out your soaked gadgets in rice. Keep digging and you finally get to the likely source of the trick: for many decades, rice was used to keep camera equipment and film dry in tropical locations.
Photographer M. When the first phone was dunked into a pile of dry rice is impossible to say — but there is an ironic symmetry in the fact that we still use the method to keep our primary photography equipment safe.
So, does the trick work? In , Gazelle. Of the seven household desiccants they tested, uncooked rice was the least absorbent, behind cat litter, couscous, oatmeal, and instant rice. Craig Beinecke, co-founder of TekDry, a company that provides "emergency electronic device rescue services" says so too.
TekDry has developed a fancy machine that resembles a suitcase bomb and uses negative pressure and low heat to actively expel fluids out of a properly doused phone in roughly 20 minutes. Of course that study should be taken with a grain of… salt. The research was entirely funded by a company whose business depends on the rice trick being ineffective. And every time a phone falls into a toilet or sink, the trick is transmitted anew, from parent to child, from friend to friend.
Countless testimonials speak to the efficacy of rice. It worked every time. The rice trick does have one unique and very powerful property. The worst thing you can do to a wet phone is to power it up before it dries completely — doing that is cell phone homicide in the first degree. Your smartphone got wet. Here's what not to do first.
