You’re standing over the sink, your heart is sinking faster than the iPhone you just dropped into the dishwater, and your first instinct is to sprint to the pantry. You grab the Uncle Ben’s. You bury that expensive piece of glass and silicon in a mountain of dried grains. But honestly, if you're wondering about a phone in rice for how long, the answer might be "never." Or at least, not for the reasons you think.
It’s a tech myth that has persisted for decades. We’ve all heard the success stories. A friend of a friend dropped their Samsung in a lake, left it in Basmati for three days, and it "magically" turned back on. Here’s the cold, hard truth: the rice didn't save it. The air did. Or maybe just plain old luck. When we talk about how long a phone should stay in rice, we’re usually ignoring the chemistry happening inside the charging port and under the logic board. Corrosion doesn't wait for the rice to get hungry.
The 24-Hour Myth vs. Reality
Most "experts" on TikTok or old forums will tell you 24 to 48 hours is the sweet spot for a phone in rice for how long. They say the rice acts as a desiccant, pulling moisture out of the tight crevices of your device.

It doesn't.
In fact, rice is a pretty mediocre desiccant. If you compare it to silica gel—those little "Do Not Eat" packets you find in shoe boxes—rice is basically useless. A study by the folks at TekDry actually showed that leaving a device in the open air was more effective at removing moisture than putting it in a bowl of rice. Why? Because rice grains are large. They block airflow. By burying your phone, you're essentially creating a humid little tomb that prevents evaporation.
If you absolutely insist on using the rice method because you have no other options, you’re looking at a minimum of 48 to 72 hours. But there’s a massive catch. While you’re waiting for those three days to pass, the minerals in the water—chlorine, salts, magnesium—are reacting with the electricity in your battery. This creates a crusty green gunk called corrosion. It eats through copper traces like acid.
What Happens Inside the Grains
Think about the dust.
Rice is dusty. Starchy, fine, white powder coats every single grain. When you shove a wet phone into a bag of rice, that water mixes with the starch to create a literal paste. This goop gets lodged in your charging port, your speakers, and your headphone jack (if you still have one).

I've seen repair technicians open up "rice-cured" phones only to find the interior looking like a bowl of horchata. It’s messy. It’s abrasive. It can actually cause more mechanical damage than the water itself.
Apple actually updated their support documentation recently to explicitly warn against this. They point out that small particles of rice can damage your iPhone. They recommend "air drying" instead. It’s a shift in the narrative that’s been a long time coming. For years, we treated rice like a magic ritual, but the tech has changed. Modern phones are built with tight seals and adhesive gaskets. Rice can't reach the water trapped behind a screen assembly. It just sits on the surface, looking busy while your motherboard fries.
The Science of Water Resistance (IP Ratings)
Most flagship phones today come with an IP68 rating.
- The "6" means it's dust-tight.
- The "8" means it can survive immersion in water (usually up to 1.5 meters for 30 minutes).
If you have a modern iPhone 15 or a Samsung Galaxy S24, a quick dunk in the sink isn't a death sentence. The phone is literally designed to keep the water out. The problem is usually the "Liquid Detected" warning that pops up when you try to charge it. Your phone is protecting itself. It's shutting down the power to the port so it doesn't short circuit.
In this scenario, asking about a phone in rice for how long is the wrong question. You don't need to dry the inside; you just need to dry the port.

Better Alternatives to the Rice Bowl
If you're panicking, do this instead of raiding the kitchen:
- Silica Gel: If you’re a hoarder of those little packets, now is their time to shine. Put them in a sealed container with the phone. They are engineered to absorb moisture. Rice is engineered to be delicious with stir-fry.
- A Simple Fan: Point a fan directly at the charging port. Moving air is the king of evaporation.
- Patience: This is the hardest part. You need to wait.
Why Some People Swear by Rice
Psychology is a funny thing.
When your $1,000 phone gets wet, you feel helpless. Doing something feels better than doing nothing. By putting the phone in rice, you are forced to stop touching it. You stop trying to turn it on (which is the #1 way to kill a wet phone). You stop plugging it in.
The rice acts as a "time-out" box. The phone survives because it was allowed to sit and dry naturally, and the owner gives the credit to the rice. It’s a classic case of correlation not being causation. The phone lived despite the rice, not because of it.
The Step-by-Step Survival Protocol
Forget the grains. If you’ve just dropped your device, follow this sequence immediately. Speed is everything.
First, power it off. Do not check if the camera still works. Do not try to send a "OMG my phone is wet" text. Just kill the power. This stops the flow of electricity, which is what actually causes the catastrophic damage when it hits water.
Second, strip it down. Take off the case. Pop the SIM tray out. If you're using an older device with a removable battery, get that out of there. You want to create as many openings for air to enter as possible.
Third, pat it dry. Use a lint-free cloth or a paper towel. Don't use a hair dryer! Heat is the enemy of phone glue. You'll melt the seals and potentially damage the screen's liquid crystals. Use a vacuum cleaner if you have a narrow attachment to try and suck water out of the ports, but never blow air into them—that just pushes the water deeper.
The Saltwater Exception
If you dropped your phone in the ocean, the phone in rice for how long debate is irrelevant. Your phone is likely on its way to the grave unless you act weirdly. Saltwater is incredibly corrosive.
In this specific, terrifying instance, some technicians actually recommend rinsing the phone in fresh water or 90% isopropyl alcohol. It sounds counterintuitive to get a wet phone wetter, but you have to get the salt out. Once the salt dries and crystallizes, it’s game over.
When to Call It and See a Pro
Sometimes, DIY isn't enough. If you see fogging inside the camera lens, there is moisture trapped in the optical stack. Rice won't pull that out. If the screen has "bruising" or flickering lines, the digitizer is compromised.
Professional ultrasonic cleaning is the only real "cure" for internal liquid damage. Shops use a special machine that vibrates at high frequencies to break up corrosion and mineral deposits that rice simply can't touch. It usually costs between $50 and $100. Compared to the price of a new flagship, it's a bargain.
Summary of Actionable Insights
Stop treating your pantry like a repair shop. If you’ve been wondering about phone in rice for how long, the most important thing to remember is that the "rice method" is largely a myth that risks introducing dust and starch into your device.
- Skip the rice: Use open air and a fan for 24 to 48 hours.
- Vertical orientation: Lean the phone against something with the charging port facing down so gravity can help.
- Avoid heat: No ovens, no sunbeams, no hair dryers.
- The 90% Rule: Use 90% or higher Isopropyl alcohol on a Q-tip to clean the charging port if it looks "crusty" after drying.
- Invest in Silica: Buy a dedicated "phone drying kit" or a handful of silica packets to keep in your junk drawer for emergencies.
The best thing you can do for a wet phone is absolutely nothing. Turn it off, set it in a breezy spot, and wait. If it doesn't turn on after two days of air drying, rice wouldn't have saved it anyway. It's time to head to the repair shop and let the professionals handle the surgery.
