When the weather gets cold, does your phone’s response speed slow down?

No. However, when the weather is wet, the speed of the phone will slow down.

Usually during the summer, your mobile application software will slow down by 15%. The scientific explanation behind this has to do with the propagation of radio waves. The increase in water vapor in the air leads to the weakening of radio waves, especially in the high-frequency bands.

It can be seen that the high water vapor content in the humid air in summer weakens the signal strength and causes a slight delay when the application software runs.

Extended information

Radio signals are weakened in weather with higher humidity, including moisture, rainfall, sleet, and snowfall.

The impact of this interference is more obvious for high-frequency signals, especially for high-frequency signals above 1 gigahertz. In other words, LTE services above this range will be extremely prone to problems in this weather.
