After updating to 12.3.1, a number of users noticed that their iPhones occasionally vibrated in a manner that’s unusual. What made matters awkward, was that the vibrations were quite audible, even when the phone was set to silent.
If you’re alone and this happens, that shouldn’t be much of a problem. However, if you’re in a place that requires everyone to turn off their phone, this sudden noise could be quite disruptive.
If you’re wondering; why does my iPhone vibrate so loud/strong? You’re in good company. The main reason is that two mics are resonating and amplifying one another’s signals. That’s why the buzzing sound is odd, loud, and unpredictable.
The full details about the causes and fixes are right here, so read on!
What Is Causing My iPhone to Vibrate So Loud/Strong?
This vibrating noise is pretty unusual, thus, the formal channels haven’t up to this date issued any specific diagnostics. An initial prognosis is available though, and the cause is often one of the following reasons:
There’s a consensus that a-synchronized mics would create a vibrating signal that’s moderate and predictable. With the rare probability that both mics vibrate simultaneously, you’d get a much stronger signal plus some noise.
There’s also a one-off mention of iPhones with a vibration that’s so weak, it’s almost indiscernible. The reason could be the reverse of this situation, where both signals are out of phase and cancel one another.
Issues in the 12.3.1 Update
There’s a slight correlation between getting the 12.3.1 update and the onset of these weird vibrations.
It’s actually quite possible that the software could be triggering this noise.
Loose Taptic Engine
iPhone has recently equipped some of its models with extra-strong Tapic engines. This could contribute to the loudness of the vibrations. The odd noise could be caused by a loose engine.
The iPhone 6S is among the releases with that powerful engine.
iPhone menus are rife with all kinds of settings, and you should check routinely whether you have the right ones.
For example, one of the settings allows vibration on silent, or vibration on ring. This could be the reason why the vibrations are audible, even when the phone is on silent.
How Can I Fix the Extra Loud/Strong Vibrations in My iPhone?
iPhones are a bit hard to troubleshoot, so the best approach is to focus on the software and settings. More often than not, this should take care of the problem. This is also a proper step to rule out common issues.
After that, a visit to the specialists would be necessary. Check your warranty date, and if you are within the one-year limited warranty period, then you can get the phone fixed, including spare part replacement.
Update the iPhone Software
Various users who have faced the loud vibrations problem tried to update their OS to the next version. Many reported that moving on to the 12.4 sorted things out.
If you try this and nothing is changed, or if you already have the latest update, then you can move on to the next cause.
Check the Settings
There are a few possibilities you should check out here. The first one is the silent/ring vibration option.
- Go to the sound settings, and see which one is selected: Vibrate on silent or vibrate on ring. Then, try turning off the silent selection.
- There’s also a slider that changes the ringer and alerts volume. You can decrease the slider and test the vibration signal.
- Another important vibration setting is in the accessibility menu. You can select phone noise cancellation to decrease the vibration intensity.
Take the iPhone to a Specialist
iPhones are a bit on the sophisticated side, and that’s part of their charm. However, this also means that whenever they start glitching, there’s only so much you can do. Ans eventually, you need to solicit the services of a specialist.
If your iPhone is acting up within the first year, then you would get an all-inclusive service from any of apple’s stores. Otherwise, the repairs could be a bit costly.

Unpredictable sounds are often annoying, and they’re more so if your iPhone starts making a loud noise in the middle of a meeting.
The issue of having an iPhone that’s making a loud/strong vibrating noise isn’t too common. So until now, we don’t have all the details on why it’s behaving like that.
Fortunately, we have sufficient data to troubleshoot simple issues like software bugs or incorrect settings. In most cases, this is enough to get the phone back into its mint state.
The other possibilities include hardware issues, like a loose engine. This is definitely a matter that only the pros can work on.
