The Apps That Use the Most Mobile Data, Ranked

We partnered with Holafly to identify the apps that have the biggest appetite for megabytes to help travelers avoid that big footprint.

We used the My Data Manager app to test data usage across the most popular apps on an iPhone 15 Pro Max and an Android Xiaomi Redmi 9. For each app, we first shut down all other apps and switched off Wi-Fi access, then started a separate stopwatch as the app was launched. The app was used for five minutes and the total data usage (MB) was recorded from My Data Manager reports.
