The number of smartphone handsets in use globally has risen from 2.99 billion in 2015 to 7.42 billion in January 2025. That’s an increase of over 4.4 billion devices, showing just how much smartphones have become a basic part of life around the world. However, while the numbers keep rising, the pace of growth is clearly slowing down, revealing that the market is maturing. The explosive growth years are behind us.
