OnePlus phones are popular for a reason — fast charging, clean software, and speakers that sound good for the price. But like every phone, a OnePlus that goes for a swim sounds terrible afterwards: muffled, quiet, or crackly, even when everything else works. Water sits over the speaker mesh and stops it vibrating properly. The fix is straightforward, and it does not need a repair shop visit in most splash cases.

OnePlus does not ship a built-in water-eject feature, so you will use a web-based water-eject tone played through the phone itself. Here is the safe way to do it, and what is different about OnePlus phones.

First, do these three things straight away

1. Get it out of the water and do not charge it. Do not plug in a charger while the USB-C port might be wet. OnePlus phones often show a moisture warning — take it seriously and wait until the port is fully dry.
2. Dry the outside. Wipe the phone with a soft, lint-free cloth, paying attention to the bottom edge where the speaker and USB-C port sit. Hold the phone speaker-side down and give it a gentle shake so loose droplets fall out. Do not shake it violently, and do not blow into the speaker.
3. Give gravity a few minutes. Let the easy water drain out before you run any tone. If the screen is flickering, the phone is hot, or anything smells odd, switch it off and get it checked instead of continuing — those are signs of water inside the phone, not just in the speaker.

Most recent OnePlus flagships carry an IP64 or IP65 rating, and some models go further, but water resistance is not waterproofing, and it wears down with age, drops and repairs. Check your exact model’s rating if you are unsure, and never assume an older or previously repaired OnePlus is as sealed as it was new. The general first-aid steps in our guide to what to do when a phone is dropped in water apply just the same.

Where the speakers are on a OnePlus

Most modern OnePlus phones, from the Nord range up to the numbered flagships, have stereo speakers: a main speaker on the bottom edge, next to the USB-C port, and a second speaker built into the earpiece at the top. Both can trap water, and both can sound muffled after a dunk.

Run the tone with the bottom speaker pointing down first, wipe away any droplets, then turn the phone over and repeat with the earpiece pointing down. If only one speaker sounds muffled — music is fine but calls sound dull, or the other way round — focus on that one, but run a cycle for both anyway. Water rarely respects boundaries.

How to eject water from a OnePlus speaker with a tone

A water-eject tone is a low-frequency sound that vibrates the speaker diaphragm and pushes trapped droplets out of the mesh. It is the same principle behind the Apple Watch’s water-eject feature, and it works on any phone speaker, including OnePlus.

1. Turn the media volume up to around three-quarters — loud enough to feel the vibration, not at maximum.
2. Open the free speaker cleaner in your OnePlus browser and run the water-eject sound, holding the phone with the bottom speaker pointing down and slightly away from you.
3. Let the tone play through fully, then wipe away any droplets that appear around the grille.
4. Repeat two or three times, with a short pause between runs. If the sound is still muffled, that usually means water is still sitting in the mesh or the phone needs more drying time — not that you need a louder tone.
5. Flip the phone and repeat with the earpiece pointing down.
6. Play a song and make a short test call afterwards and compare. The sound should be noticeably clearer, even if it is not perfect yet.

The method is the same one we describe for ejecting water from a Samsung speaker and for ejecting water from a Pixel speaker — the only OnePlus-specific part is the speaker layout and the OxygenOS settings below.

Check your OnePlus settings afterwards

A wet speaker sometimes gets blamed for what is actually a settings problem, especially after a phone has been in water and handled a lot. Before you conclude the speaker is damaged, check these:

• Media volume. Make sure the media volume is actually turned up, and that you have not left the phone on silent or vibrate with media muted.
• Bluetooth. If the phone is still connected to earbuds, a car stereo or a Bluetooth speaker, sound will go there instead. Turn Bluetooth off for the test.
• Mono audio and balance. In Settings, check the accessibility audio settings. If the balance has been knocked to one side, one speaker will sound faint.
• App volumes. Some apps have their own volume controls. Test with the phone’s own music or video app, not only one streaming app.

If the speaker sounds fine in one app and muffled in another, the problem is the app, not the hardware.

Drying time: what to expect

Do not expect a miracle in two minutes. A lightly splashed speaker often clears after a few tone runs. A phone that went fully under water can take several hours to dry out completely, and the sound may improve gradually as the last moisture evaporates. Leave the phone in a well-ventilated room, speaker-side down on a dry cloth, and resist the urge to keep testing it every five minutes. Our guide to how long it takes to get water out of a phone speaker sets out realistic drying times for different levels of soaking.

Two things to avoid while it dries: rice, which does very little and can leave dust in the ports (see does rice fix a wet phone), and heat — no hair dryer, no radiator, no direct sun. Warm air can push moisture deeper into the phone and damage the battery.

If the water was not clean water

Fresh-water splashes are the easy case. If the phone went into the sea, a pool, or a sugary drink, rinse the affected areas gently under clean, fresh water first — briefly, with the phone powered off if possible — then dry and run the tone. Salt, chlorine and sugar all leave residue that keeps corroding contacts long after the water is gone. The same advice applies to salt water in a phone speaker, and it matters just as much for a chlorinated pool.

When it is a repair job, not a drying job

Get the phone looked at if the speaker still crackles or stays silent after 24–48 hours of drying, if the sound is distorted at every volume, if the phone gets unusually hot, or if you see swelling, a bulging back, or a battery warning. Those are signs of damage beyond surface water. Our guide to telling a blown speaker from a blocked one will help you judge which side of that line you are on, and a OnePlus service centre or a reputable repair shop can test the speaker properly without you having to open the phone yourself.

Frequently Asked Questions

Does OnePlus have a built-in water eject sound?
No. OnePlus phones do not ship with a water-eject feature, so you use a web-based water-eject tone played through the speaker instead — the method described above.

How do I eject water from my OnePlus Nord speaker?
The same way as any OnePlus: run a water-eject tone with the bottom speaker pointing down, wipe away droplets, repeat for the earpiece, then let the phone dry. The Nord’s speaker layout is the same stereo arrangement as the flagships.

Can I charge my OnePlus while the speaker is wet?
Not through the USB-C port. Wait until the port is fully dry, and heed any moisture warning the phone shows. Wireless charging is the safer option in the meantime, if your model supports it and the outside of the phone is dry.

Will a water-eject tone damage my OnePlus speaker?
No, when used at a sensible volume for a few short runs. Damage comes from playing a soaked speaker at maximum volume for a long time, or from heat and poking — not from the tone itself.

My OnePlus speaker is still muffled after two days. Is it broken?
Possibly. If drying and several tone runs have not helped, the mesh may be blocked with debris or the speaker may be damaged. Get it inspected rather than repeating the same steps.

Try it now

If your OnePlus speaker sounds muffled right now, run the free speaker cleaner with the bottom speaker pointing down, repeat for the earpiece, then give the phone a few hours to dry. In most splash cases, that is all it takes.
