    Default nexus 4 charger making a high pitch sound?

    my nexus 4 charger (stock charger) is emitting high pitch noise... and is this guy correct? --> "Basically, instead of using mains frequency AC conversion in a transformer (50Hz, big transformer), the system uses high frequency (15kHz+) transformers, which can be much much smaller. A vibrating transformer is all you can hear. Not all chargers do it, you're just unlucky."

    My Nexus 4 charger had the same problem and just didn't charge anymore. Seems like some people just got a crappy charger with the phone. You can get another one from the store or check T-Mobile to see if they sell the same charger since they sell the phone.

    yeah the factory charger is cheap and if it works will eventually charge at a snails pace and make a sound coming from the charger. this is with two chargers i got from google. get an andru charger and be done with it.

    You are correct, the power supply in these little wall wart type supplies is running at a high frequency, and there generally is a transformer in the supply, and that is what is vibrating at the high frequency. Depending on your hearing, and how loose the lamination in the transformer are, you may or may not hear it. It could be annoying, but it causes no reliability problem.

    I get the same noise. However it goes away when I plug the phone into the charge cable.
