How to fix iPhone 7 muffled speakers (water damage)

Apple officially announced that the new iPhone 7 and iPhone 7 Plus models are splash and water resistant. With a rating of IP67, the two phones can survive being submerged in water for 30 minutes up to a depth of 1 meter. Why is it then, that people are experiencing iPhone 7 muffled speakers?

We have had people getting in contact with us, here at Repairly, about their iPhone 7 having muffled speakers. It turns out lots of people think that putting their iPhone 7 is a great party trick!

Apple’s Recommendations

The big caveat here is that Apple does not cover liquid damage under the warranty. Recommendations from Apple of activities to avoid include :

  • Swimming or bathing with the phone
  • Exposing it to high-velocity water such as when showering, surfing jet, etc
  • Exposing it to steam
  • Intentionally submerging the phone in the water

Now, it’s impossible to avoid liquid encounters completely and we get it, it happens. While your iPhone 7 or iPhone 7 Plus should normally be able to breeze through minor incidents and splashes, recently a Reddit user reported using the device to listen to music in the shower and found that the sound was getting muffled. This is probably due to the water getting in through the tiny cavities in the speaker and causing a blockage.

With the Apple Watch Series 2, Apple included a nifty way to make use of the speakers to push out the water and clear up the speakers. It’s baffling why they have decided against including a similar mechanism in the new iPhones.

How To Fix Your iPhone 7 Muffled Speakers

Nevertheless, there is a super handy app called Sonic that can mimic that function of the Apple Watch by emitting a sine wave at a frequency which ejects the water droplets from the speakers.

1. Download the Sonic app from the App Store
2. Set the tone to anywhere between 160-170 Hz and click play. 165 Hz has been reported to be most effective, however, feel free to experiment and see what works best
3. Take a piece of cloth and wipe off the droplets

Ta-da, that should result in your iPhone 7 or iPhone 7 Plus no longer being muffled. We’d be happy to hear if this worked for you, please let us know our experience!
