How much data do Instagram, TikTok and Reels use while travelling?

Social apps don't publish data-per-hour figures, and the answer depends on how you scroll. This guide gives you a 15-minute test for your own number and the settings that bring it down.

Short answer

Instagram, TikTok and similar apps don't publish data per hour, and feeds that autoplay video use data much like video streaming. Text and photo browsing uses far less. To get your figure, reset the phone's counter, scroll for 15 minutes and multiply by four. Data saver settings and Wi-Fi-only uploads cut it.

Why is there no single number for social media data?

Streaming services such as Netflix publish per-hour figures because you choose one quality and watch one thing. Social feeds are a mix: photos, short videos that start on their own, ads, Stories and messages. Most apps also preload the next few videos so swiping feels instant, so you pay for some videos you never watch.

So we don't print a single "MB per hour" figure for Instagram or TikTok. Any number would be made up. There are two honest ways to plan:

Treat video-heavy scrolling like video streaming. For planning, our estimator uses 0.17–0.7 GB an hour. That sits between Netflix's mobile Save Data figure (about 6 hours per GB) and its Medium setting (up to 0.7 GB an hour). It is an assumption, labelled as one.
Measure your own scrolling. This takes 15 minutes and is far more accurate for you.

Our social range is a planning assumption, set between Netflix's Save Data and Medium figures because feeds are mostly short video. Replace it with your own 15-minute test. Log scale.

How do I measure my own Instagram or TikTok use?

Switch Wi-Fi off so the test runs on mobile data.
Write down the app's current figure. iPhone: Settings → Cellular, then scroll to the app. You can tap Reset Statistics at the bottom to start from zero. Pixel: Settings → Network & internet → SIMs → App data usage.
Scroll the way you normally do for 15 minutes. Reels, Stories, your feed, whatever you would do on the trip.
Read the new figure. Subtract, then multiply by four for an hourly rate.
Repeat with data saver on (see below) to see what the setting is worth for you.

Example figures only, to show the arithmetic. Fill in your own test results.
Example worksheet	Your 15-min test	Per hour (× 4)	Trip: 1 h/day × 7 days
Feed and Reels, default settings	e.g. 120 MB	e.g. 480 MB	e.g. 3.4 GB
Same, with data saver on	e.g. 60 MB	e.g. 240 MB	e.g. 1.7 GB
Messages and photos only	e.g. 10 MB	e.g. 40 MB	e.g. 0.3 GB

Which settings cut social media data?

Menu names change between app versions, so look for these words rather than exact paths:

Instagram: under Settings and activity, look for Data usage and media quality. Turn on the data saver option and make sure Upload at highest quality is off on mobile data.
TikTok: under Settings and privacy, look for Data Saver.
Facebook: under Settings & privacy, look for media or video settings and turn off autoplay on mobile data.
X: under Accessibility, display and languages → Data usage, turn on data saver and set video autoplay to Wi-Fi only.

System settings help as well. On iPhone, Low Data Mode for the travel line stops apps using the network when you're not actively using them and turns off Background App Refresh, Apple says. On Android, Data Saver and per-app background data limits do a similar job.

How much data does posting photos and videos use?

Uploads are easier to predict than scrolling. The data used is about the size of what you send, after the app compresses it:

Photos: on iPhone, swipe up on a photo (or tap the info button) to see its file size. Phone photos are typically a few MB each. RAW or very high-resolution formats are much larger.
Video: Settings → Camera → Record Video on iPhone lists the approximate size of one minute for each resolution and frame rate. 4K at 60 fps is several hundred MB per minute on recent models, so a few long clips can cost more than a day of browsing.

Two easy habits: film at 1080p if the clip is only for Stories, and post long videos from hotel Wi-Fi. If cloud photo backup is on too, the same video may upload twice. See stopping backups on the travel line.

Worked example: a week of moderate scrolling

Example numbers, not an offer

Suppose your test gives 480 MB an hour with default settings and 240 MB with data saver on. You scroll about 45 minutes a day for 7 days, and post five 30-second clips at 1080p.

Scrolling with data saver: 0.75 h × 7 × 240 MB ≈ 1.3 GB
Scrolling on defaults: 0.75 h × 7 × 480 MB ≈ 2.5 GB
Clips: check the per-minute size your camera shows and multiply by 2.5 minutes in total.

Add your maps, calls and other activities in the GB estimator to see the whole trip.

Do social apps use data when I'm not scrolling?

They can. Feeds refresh, messages sync and some apps prefetch content for later. On the first evening of a trip, open the per-app list for the travel line and see which apps used data while the phone sat in your pocket. Turning off Background App Refresh for social apps (Settings → General → Background App Refresh on iPhone) is usually enough. You still get messages from apps that use push notifications.

Is messaging cheaper than social media?

Much cheaper, as long as it is mostly text. A text message is tiny next to a video, so a day of chatting barely moves the counter. What costs data in chat apps is media: photos, voice notes, and above all videos that download automatically in busy groups. That is why WhatsApp's media auto-download setting matters more than how much you type. For a trip, set auto-download on mobile data to nothing or photos only, and tap to download a video when you actually want it. The updates and backups guide has the exact switches.

Frequently asked questions

Does TikTok use more data than Instagram?

Neither app publishes a figure, and it depends on settings and what you watch. Both lean on full-screen video, so an hour of either can use video-streaming amounts. Run the 15-minute test in each app to compare them on your own phone.

Does posting a Story use a lot of data?

An upload costs roughly the size of what you post. A short clip filmed in 4K can be tens to hundreds of MB. On iPhone, Settings → Camera → Record Video shows the approximate size of a minute of video for each format. Post longer clips from Wi-Fi or film at a lower resolution.

Will social apps work after my daily full-speed data runs out?

Messages and text posts usually still load. Video feeds will be slow or show placeholders. Check the speed after the cap on your plan and lower your expectations for Reels and TikTok on that line.

Do social apps use data in the background?

They can: refreshing feeds, preloading video and syncing messages. On iPhone, turn off Background App Refresh for them. On Android, restrict background data per app. Then check the per-app counter after a day.
