It is likely that, at some point, you have heard how connect your iPhone to a chargerthis emits a slight beepwhich sometimes ends up being annoying, and many times, we don't know where it comes from until we realize that it is the charger itself. This article may even have revealed the reason for you. For me, at least, it took me a while to find out its origin.
This has a very simple and interesting explanation, since using an accessory that emits this can be dangerous, both for you and for the iPhone itself, which could suffer battery problems.
What to do if a charger beeps when it is working
Well, first we will see why it sounds, and there are several reasons, which would indicate something more serious or less important, although all of them require attention, since, as we said, it is not a good thing.
- Vibration of internal components (normal): Some chargers, especially cheaper or older ones, may make a high-pitched sound due to vibration of electronic components such as coils or transformers. This is called “coil whine” and, although annoying, it is not usually dangerous, so it does not mean that if you bought it on AliExpress and it rings, it will explode.
- Overload or bad contact: If the charger is powering a device that consumes more power than it can deliver, or if there is poor contact on the plug or cable, it may generate a beep as a warning or sign of instability, so it is important to always check the power is adequate on both devices.
- Voltage or power quality problems: An unstable electrical source, with voltage spikes or dips, can cause the charger to react by making sounds. This can happen especially with chargers that have internal protection.
- Charger damage or wear: If the charger has been dropped, damp, or aged, the beeping may be a sign of impending failure. It is advisable not to continue using it if the sound is new or has increased over time.
- Problems with the connected device: Sometimes the problem is not the charger itself, but the connected device (phone, tablet, etc.), which causes erratic charging. Test the charger with another device to check.
In short, if your charger beeps from the beginning, is new, and has not suffered drops or other types of problems, it may be normal, and it is simply annoying. However, in other types of cases (the majority), it is likely due to a problem, from poor quality or impact, to not being really compatible with your iPhone, so you could be supplying power spikes that damage the battery over time, not being good for it.
That is, if the iPhone charger beeps, and you don't know for sure why, the best thing would be to buy anotherthey are currently very cheap, and we will avoid unnecessary risks, since any problem caused by this could cost us more.
