The iPhone 7 is out and Apple's latest has already netted spectacular sales numbers in its opening week.
That's pretty much par for the course and, apart from an iOS 10 blip, the handset has launches with very few problems. Naturally, that can't last.
The latest issue comes from a number of users who are saying that their handsets start to emit a strange hissing noise when they're being used intensively. Here's an example.
The poster says that he doesn't even have to be particularly close to the device to hear it, that the hiss is perfectly audible while the phone is lying on the desk. Is this a major issue? Well that level of noise might suggest something inside the phone is getting seriously overloaded, which is a definite concern in a world where 2.5 million Samsung Galaxy Note 7's were just recalled because they have a habit of exploding.
Now that was a battery issue and there's no suggestion that the iPhone 7 has a problem with the battery. It does have a seriously powerful A10 chip and this might just a consequence of that extra hardware inside. This doesn't seem to be a widespread issue with the phone, even tested under the same conditions.
There's no official word from Apple yet.
