Instagram has a video preload feature, which automatically triggers video buffer and playback. Save your precious data usage by disabling this feature from running on a mobile data connection.
The video autoplay is a nice feature but it secretly consumes mobile data when the user is not aware. So in a normal scenario, it preloads the video and plays when the phone is connected over a mobile data network. Thus it consumes some mobile data. In order to save on those precious bytes, follow this simple guide.
Open the Instagram app and go to your profile.
Select the three vertical dots to open the Settings menu. Scroll down to the Video section and select Preload.
From the Preload option, select: Only on WiFi.
After this, the Instagram app will preload the videos only when the device is connected to a WiFi network.
