How Smartphone Usage is Growing — And What It Means for Mobile Ads

The smartphone revolution is here, and it’s only getting bigger. With billions of users worldwide and staggering year-over-year growth, smartphones are transforming how we communicate, consume media, and even shop. This explosive growth means a massive opportunity for mobile advertisers, as more people spend increasing amounts of time on their handheld devices.

In this post, we’ll dive into the latest smartphone usage data, explore regional trends, and explain why this growing market provides fertile ground for mobile ads. All data in this post is sourced from Priori Data (https://prioridata.com/data/smartphone-stats/).


The Monumental Growth of Smartphone Usage

As of 2024, there are approximately 4.88 billion smartphone users worldwide, accounting for 60.42% of the global population. This is just the beginning.

This growth reflects a steady 14.9% annual increase in smartphone adoption globally. Even more striking, the number of smartphones in use globally totals 7.21 billion devices, as many users own multiple devices.

Smartphone Adoption Over Time

Let’s take a closer look at how smartphone ownership has grown over the years:

The Mobile Ad Goldmine: Why This Matters for Advertisers

Unprecedented Reach

With billions of users and growing, smartphones offer unparalleled reach for mobile ads. Markets like India and China are especially enticing due to their sheer size and increasing penetration rates.

High Engagement

The amount of time people spend on their devices ensures that ads have a higher chance of being seen. Whether it’s video ads, banner ads, or in-app promotions, mobile advertising benefits from prolonged user engagement.

Demographic Targeting

Smartphones also enable precise targeting. Advertisers can tailor campaigns based on age, location, and even behavior (e.g., how much time users spend on their devices).


The Dominance of Android and iOS

The smartphone operating system market is concentrated, with Android holding a 70% share and iOS capturing 29%. This duopoly simplifies ad placement for marketers, as campaigns only need to be optimized for two platforms.


The Road Ahead: What to Expect by 2029

By 2029, the number of smartphone users is expected to hit 6.38 billion, while the global smartphone market will continue to grow. As adoption increases in developing regions and technology becomes more affordable, mobile advertising will expand into untapped markets.

Whether you’re targeting young adults in urban areas or tapping into the growing markets of India and China, the smartphone revolution is a goldmine for brands. With high engagement rates, precise targeting capabilities, and a growing user base, mobile ads are poised to become the dominant form of digital marketing.
