Radio Tuner a glass body allows radio waves to pass through and better facilitates wireless charging, but unless utilized properly, could make the phone more fragile. Mobile phones run on so-called embedded chipsets, which are designed to perform one or a few dedicated functions, often with real-time computing constraints. They are embedded as part of the complete device including hardware and mechanical parts. Thus their CPU (Central Processing Unit) performance is vital for the daily user experience and people tend to use the clock rate of the main CPU that's in the heart of the chipset to compare the performance of competing end products.
