Hissing sounds on certain iPhone 7s? According to 9to5mac.com, certain people have reported that their iPhone 7s made hissing sounds whilst under heavy workloads, according to them, the source of the purported hissing sound is yet to be determined and, also, it is not yet known where the sound is coming from, though, the most likely suspect is the processor. Possibilities could be: sounds from a revolutionary cooling system, an overworked and cooking hot processor in its death throes or just unsubstantiated claims. Are we approaching the limits of power, performance and miniaturization? Or is the rush to compete leading to poor quality control and/or overoptimistic performance expectations? At the end of the day, consumers’ rejection and one or two costly recalls will restore some sense to the unconscionably hasty competitor. Make haste slowly.
