I used to buy a weekly bundle every Monday and somehow it was always finished by Thursday, even though my routine hadn’t changed one bit. The culprit wasn’t calls or texts. It was the three apps sitting right on my home screen: YouTube, TikTok and Instagram.
The good news? Each of these apps has a built-in data-saver switch that most people never touch. Flip all three and your bundle suddenly starts behaving itself — no root access, no third-party apps, and you can still watch everything you enjoy.
Why YouTube, TikTok and Instagram drain data so fast
These apps are built to keep your thumb moving and your screen lit, and every second of that motion costs megabytes. Autoplay is the biggest offender: YouTube rolls straight into the next video, TikTok barely pauses at all, and Instagram Reels keep feeding you clips before you’ve finished the current one.
Then there’s preloading. Your phone quietly downloads the next few videos in the background so they start instantly. Lovely on Wi-Fi, brutal on a mobile bundle. And finally, quality — on a strong 4G signal these apps happily stream in HD, which can use several times the data of the same video in standard definition, even though on a small phone screen the difference is barely noticeable. Add the three together and a “quick scroll” can quietly burn through a few hundred MBs before you realise half an hour has gone.
YouTube — turn on Data saving mode
Good news first: YouTube has a proper built-in data saver, and it takes less than a minute to switch on. Tap your profile picture, open Settings, and look for the Data saving option — turn it on. From then on, YouTube keeps playback at a lower quality on mobile data, so each video sips instead of gulps.
Two more tweaks in the same area. In Settings, open Video quality preferences and set “On mobile networks” to Data saver — this stops YouTube jumping to HD every time your signal is strong. Then find Autoplay in Settings and switch it off for mobile data, so videos don’t start playing while your phone is lying on the table. Small switches, but together they genuinely slow the drain.
TikTok — switch on Data Saver and clear the cache now and then
TikTok is probably the hungriest of the three because it preloads video after video while you scroll. Open your profile, tap the three-line menu at the top, and go to Settings and privacy. Scroll down until you find Data Saver and turn it on — TikTok will then load videos at a lower resolution and stop downloading so aggressively in advance.
While you’re in that same menu, it’s worth opening Cache & cellular data and tapping Clear cache every few weeks. All those preview clips pile up in your phone’s storage, and clearing them out gives TikTok a fresh, lighter start. It won’t delete your drafts or log you out, so there’s nothing to worry about.
Instagram — turn on “Use less cellular data”
Instagram’s biggest data habit is preloading: it downloads Reels and videos before you watch them so everything feels instant. You can tell it to stop. Go to your profile, tap the three-line menu, then Settings and privacy. Tap Account, then Cellular data use, and switch on Use less cellular data. From then on, Instagram won’t preload videos over your mobile connection, and Reels only load in full when you actually watch them.
Honestly, once this is on, you barely notice a difference in day-to-day scrolling. You just notice your bundle lasting longer — which is the whole point.
Habits that multiply the savings
The in-app switches above do most of the heavy lifting, but a few small habits stack nicely on top.
First, let Wi-Fi do the heavy work. If there are videos, podcasts or shows you know you’ll want later, download or save them while you’re on Wi-Fi instead of streaming them on mobile data. Takes a little planning, saves a lot of MBs.
Second, keep an eye on background data. Even when you’re not opening these apps, they can sip data in the background — syncing, refreshing, preloading. On Android, go to Settings, then Apps, pick YouTube, TikTok or Instagram, tap Mobile data and switch off Background data. The apps still work perfectly when you open them; they just stop helping themselves while you’re away.
Third, set a data warning so nothing surprises you. Android lets you add a warning at, say, 80% of your bundle — check under your SIM’s data settings. If you want to figure out how much data you actually use in a week first, do that, then set the warning just above your normal usage so you notice overuse early.
Fourth, remember these settings sit inside a bigger picture. Pair them with phone-wide data-saving tips — like restricting background refresh across the board — and the savings add up fast. And if most of your chatting happens on WhatsApp, it’s worth learning how WhatsApp data differs from regular data, because a WhatsApp bundle stretches very differently from a general MBs bundle.
Try the three in-app settings today — it honestly takes five minutes — then check your usage in the My Telenor App after a week and compare it with the week before. Most people are surprised at the gap. And with all that data you’re no longer burning through, you’ve earned a little break — pop over and play today’s Telenor quiz while you’re at it.
