Clock speed in mobile refers to the number of instructions a processor can execute per second, measured in GHz (gigahertz)
. A higher clock speed means a faster processor
. Today's fastest mobile processors have clock speeds ranging from 1.8 GHz to 3.1 GHz
. However, clock speed is not the only factor to consider when evaluating a processor's performance. The number of processor cores and the processor's die size also play a role
. To check the processor speed of an Android phone, you can use a free app called DevCheck
