Speakers are the first thing to go
If you've owned a phone for more than two years, you've probably noticed the speakers get slightly quieter or grainier over time. That's not always failure — it's usually the accumulated effect of pocket lint, dust, sweat, and micro-droplets sitting on the driver mesh. A few small habits will keep your speakers clear for the entire life of the phone.
Here are ten of the most effective, in rough order of impact.
1. Choose a case with a proper speaker cutout
The cheapest way to damage your speaker is to muffle it with a case that partially covers the grille. Even a small overhang traps humidity and lint against the mesh. When you buy a case, check that the speaker cutout is at least 1–2 mm wider than the grille on every side.
2. Vacuum lint out of the grille once a month
Pocket lint is the number one enemy of phone speaker mesh. A cheap way to remove it: put your mouth over the grille (yes, really) and quickly suck. Modern smartphone grilles are engineered to survive this. A soft toothbrush swept lightly across the grille also works. Never poke a needle, pin, or SIM ejector into the mesh — you'll deform it permanently.
3. Skip the compressed air, or use it very gently
Cans of compressed air are commonly recommended, but the pressure is often high enough to push lint *further into* the driver. If you use compressed air, keep it upright, hold it at least 15 cm from the grille, and use the shortest possible burst.
4. Rinse after beach or pool exposure
Salt and chlorine crystallize inside the speaker chamber when the water evaporates, permanently reducing volume. Rinse with fresh, room-temperature tap water immediately after exposure — before drying. Then run a sound-based water ejection to push the fresh water back out.
5. Dry the ports before charging
A wet USB-C port that gets charged can arc, corrode, and permanently damage the connector. Modern phones will warn you and refuse to charge, but it's better to dry the port with a soft cloth and blow into it gently before plugging in.
6. Keep the volume off maximum for extended playback
Playing music at maximum volume for hours cooks the voice coil. It's the same principle as running a car engine at redline for a road trip — it survives, but it wears faster. If you use your phone as a party speaker regularly, keep the volume around 80% and pair it with a cheap Bluetooth speaker for the loud stuff.
7. Avoid dropping the phone speaker-first
Speaker cones are held in place by fragile adhesive. A drop that lands on the speaker end concentrates the impact force on that adhesive and can crack the driver or knock the diaphragm out of alignment. Cases that add corner cushioning are worth it here.
8. Don't use the phone as a hot-tub companion
Steam is worse than water in some ways because it condenses inside the speaker chamber. Even IP68 phones aren't rated for sustained steam exposure. Long showers, saunas, and hot tubs are best enjoyed with the phone somewhere else.
9. Update the OS regularly
This one surprises people: sometimes muffled sound isn't hardware at all — it's a software audio bug from a bad update or a runaway codec. Keeping the OS updated resolves those before they compound.
10. Have a water-ejection tool bookmarked
Water in the speaker is going to happen. Kitchen sinks, dishwater, rain, spilled drinks. When it does, the difference between a two-minute fix and a permanent quality drop is whether you know what to do in the moment. Bookmark our tool now. Future you will thank you.
The two habits that matter most
If you only take two things from this list: keep the grille clean, and eject water fast when it gets in. Do those two things and your speakers will still sound great when your phone is old enough to feel embarrassing to unlock in public.
