Mobile apps are an essential part of our daily lives, but like a leaky tap, they can quickly drain your mobile data if you're not cautious. To avoid surprise charges on your phone bill, it’s important to understand how much data you're using across these apps—whether you're scrolling through social media, streaming videos, or making video calls with loved ones.

In this article, we’ll break down how much data some of our favourite mobile apps, like Instagram, YouTube, and TikTok, actually use. We’ll also provide some quick tips to help you manage your data more effectively, so let’s jump right in.

 

How Is Mobile Data Measured?
 

Mobile data is conventionally measured in megabytes (MB) and gigabytes (GB), with 1 GB equalling 1,024 MB.

While you don't need to memorize this conversion, it’s helpful to understand that the apps you use—and what you do on them—greatly affect your data consumption. In general, apps that involve high-quality images, videos, or audio consume more data. For instance, watching a YouTube video will use much more data than sending an emoji on WhatsApp.

Additionally, some apps do continue to run in the background, syncing or refreshing their content in real-time, or feature auto-play for videos. These are the silent data killers that can leave you wondering where all your mobile data went—which is why it’s important for us to understand how much our favourite apps use.

How Much Data Do Our Favourite Apps Use?


With the vast range of apps available today, we can dive into a world of entertainment basically anytime. However, the nature of each app means some of them will end up using significantly more data than others. Let’s take a closer look at some of the most popular apps to see how they measure up in data consumption.
 

Note: All stats provided are approximates. Exact in-app data usage and consumption will vary depending on individual use. All image and icon rights go to their respective owners.

Social Media 

Instagram


Usage
~ 400-600 MB per hour

Instagram uses approximately 400-600 MB per hour
if you’re just casually browsing through content, like
your friends’ #OOTD posts.

However, if you're watching Instagram Stories or
Reels, you can expect the data usage to be higher,
possibly approaching the figures for this other
popular social media app below.

TikTok


Usage
~ 840 MB - 1 GB per hour

TikTok, with its video-heavy nature, consumes
between 840 MB and 1 GB of data per hour. As
a short-form video app, TikTok’s constant stream
of clips demands a larger chunk of data compared
to other social media platforms.

 

Streaming Services

Spotify


Usage
Standard Quality: ~40 MB per hour
High Quality: ~ 150 MB per hour

Spotify is relatively light on data usage compared
to the video-centric streaming apps below, which
is fantastic because many of us absolutely love
listening to our favourite tracks on our daily commute.

Numerically, streaming music in standard quality
uses about 40 MB per hour, while higher-quality
audio can bump up that number to around 150 MB
per hour.

YouTube


Usage
Standard Quality: ~360 MB per hour
HD Quality: ~720 MB per hour
Full HD Quality: ~1.5 GB per hour
Ultra HD Quality: ~3 GB per hour

Like other streaming services, YouTube’s data
consumption varies greatly depending on video
quality. Streaming in standard definition (SD)
uses roughly 360 MB per hour, while high
definition (720p) consumes 720 MB. Full HD (1080p)
jumps to 1.5 GB per hour, and Ultra HD (4K) uses
around 3 GB per hour.

Netflix


Usage
Standard Quality: ~1 GB per hour
High Quality: ~3 GB per hour
Ultra-High Quality: ~7 GB per hour

Netflix is a data-intensive app, using around
1 GB per hour in standard definition, 3 GB per
hour in high definition (HD), and a hefty 7 GB
per hour in ultra-high definition (UHD).

With such figures, it’s no surprise that Netflix
tops the list of data-consuming apps, especially
when streaming blockbuster movies or
binge-worthy TV series.

Communication & Wayfinding Apps

Google Maps


Usage
~5 MB per hour

Google Maps is a staple for navigation, but did
you know it only uses around 5 MB per hour?
Already, that sounds pretty efficient, but using
features like Street View or downloading maps
will certainly push this number higher.

WhatsApp


Usage
Voice: ~18-30 MB per hour

On the communication front, WhatsApp is
lightweight for messages, but voice calls use
around 18-30 MB per hour. Naturally, video calls
on the platform would consume even more than
that. So, if you usually need to make long video
calls (for both work and personal reasons), make
sure to keep an eye on your data.

Zoom


Usage
Video: ~500 MB per hour
HD Video: ~2.5 GB per hour

Speaking of video calls, when it comes to
video conferencing apps like Zoom, data
usage jumps significantly. Case in point, a
standard one-on-one video call can consume
over 500 MB per hour, while HD video
conferences (if you need those) can consume
up to 2.5 GB per hour.

4 Simple Tips to Reduce Mobile Data Usage

Now that we've seen how much data our favourite apps consume, let’s look at how to manage your data more effectively. Here are four simple ways to control mobile data usage:
 

1. Lower the quality of videos and images.

Most streaming platforms allow you to reduce data usage by lowering video or image quality. For example, YouTube and Netflix let you set a lower resolution, which helps you save data. While the visuals may not be as sharp in SD compared to UHD, this change can significantly help if you're close to your data limit. YouTube also has a “Limit Mobile Data Usage” feature that automatically scales down video quality.
 

2. Disable auto-play for in-app videos.

Auto-play features, particularly in apps like YouTube, can consume data quickly, especially if videos continue playing while you’re away from your phone. Turning off auto-play in your settings helps prevent the app from using unnecessary data.
 

3. Connect to Wi-Fi when possible.

The easiest way to conserve mobile data is by not using it at all—rely on Wi-Fi instead. Streaming or downloading content, whether it’s videos, music, or updates, over Wi-Fi can save a significant amount of data. Apps like Spotify and Apple Music allow you to download playlists for offline listening, helping you enjoy your content without tapping into your mobile data.
 

4. Monitor which apps are using the most data.

Both iOS and Android smartphones come with built-in data management tools that show how much data each app consumes. You can also see how much they’ve used, and even set data limits to ensure you don't exceed your plan. If certain apps are consuming more data than expected, consider restricting their background data usage.
