If you ask a lot of people why they prefer Instagram to Snapchat, one of the reasons would be:
However, as shocking as it may sound, Instagram consumes way more data than Snapchat.
To prove this, I installed My data manager — a popular data tracker — on my device to monitor the data usage on both apps.
To make a fair comparison, I used both apps for 20 minutes each.
I also tried to restrict my views to stories on Instagram, but that didn’t change the results.
Do bear in mind that I enabled data saving on both Instagram and Snapchat.
You can try the experiment and let me know if you have a different result — I doubt it.
