Does putting a wet phone in rice work? What Apple actually says
Short answer
No. Rice doesn't dry a phone any better than leaving it out in open air, and Apple's support page explicitly says not to put an iPhone in a bag of rice because small particles can damage it. What works is removing the case, tapping out excess water, leaving the phone somewhere with airflow, and clearing the speaker with a pulsed 165 Hz water eject sound.
"Put it in rice" is probably the best-known piece of phone advice there is. It's also one of the least effective. It survived for years because phones that were going to recover anyway recovered while sitting in a bowl of rice — and the rice got the credit.
What Apple says about rice
Apple's support article on the iPhone liquid-detection alert lists three things not to do: don't dry the phone with an external heat source or compressed air, don't insert objects like cotton swabs into the connector, and don't put the iPhone in a bag of rice, because small particles of rice could damage it. Repair guides such as iFixit's make the same point. When the manufacturer and the people who repair the phones agree, that's about as clear as advice gets.
Why rice doesn't work
1. Water inside a phone isn't touching the rice
Rice can only absorb moisture from the air immediately around it. Water trapped behind a speaker mesh or inside a charging port isn't in contact with anything, so it has to evaporate first. Evaporation happens faster in moving air than in a sealed bowl of grain.
2. It creates dust and starch
Uncooked rice sheds fine starch dust and occasionally breaks into fragments small enough to lodge in a USB-C or Lightning port or sit on top of the speaker grille. Starch mixed with the remaining moisture turns into a paste — exactly the kind of blockage that makes a speaker sound muffled.
3. It wastes the time that matters
People who put a phone in rice tend to leave it there for a day or two and do nothing else. Meanwhile, water that could have been tapped or vibrated out of the speaker in a minute dries in place — and if it was salt water, pool water or a sugary drink, it leaves residue behind.
What to do instead
- Take off the case and dry the outside with a lint-free cloth.
- Tap the phone gently against your palm with the ports and speaker facing down.
- Clear the speaker with sound. A pulsed 165 Hz tone moves the speaker's diaphragm far enough to push water out through the grille — the same principle behind Apple Watch's Water Lock. See why that frequency works.
- Leave it in moving air. A dry room with a fan on a cool setting beats any container.
- Don't charge with a cable until the port is dry — at least 30 minutes, and up to 24 hours. Use a wireless charger if you need power.

Rice vs. the alternatives
| Method | Does it help? | Notes |
|---|---|---|
| Bowl of rice | No better than air | Adds dust and starch; Apple advises against it |
| Open air with a fan (cool) | Yes | Safest general-purpose drying method |
| Silica gel packets in a container | Somewhat | Better desiccant than rice, but still slower than moving air for internal water |
| Water eject sound (165 Hz) | Yes, for the speaker | Physically pushes water out of the grille in under a minute |
| Hair dryer on hot, oven, radiator | Harmful | Heat can weaken the water-resistance seals |
| Compressed air | Harmful | Can push water deeper inside |
So why does everyone swear it worked?
Because most water-resistant phones survive a short dunk regardless. If the phone was going to recover in a day of open air, it also recovers in a day of rice. The muffled speaker that "came back" overnight simply had its water evaporate — something that would have happened faster on a desk next to a fan, and faster still with a sound cycle.
Frequently asked questions
Is it bad to put a phone in rice?
It isn't likely to destroy a phone, but it doesn't help and can leave rice dust or fragments in the charging port and speaker grille. Apple advises against it.
How long should I leave my phone in rice?
You don't need to use rice at all. Leave the phone in a dry place with airflow instead, wait at least 30 minutes before cable charging, and allow up to 24 hours for the port to dry fully.
Is silica gel better than rice?
Silica gel is a far better desiccant than rice and doesn't shed starch, so it's the better choice if you want to use a container. Moving air is still the most effective way to dry internal water.
What gets water out of the phone speaker fastest?
A pulsed low-frequency tone around 165 Hz with the speaker facing down. Our free Water Ejector runs a 45-second cycle in your browser with no app to install.
