Most mobile phone contracts typically include a limited amount of monthly data, with some contracts being more generous than others. If your data contract doesn’t offer enough data, then you can end up running out before the end of the month. This leaves you with the option of paying more for extra data, or not having any data while out of Wi-Fi range for the rest of the month.
Neither of those options are great. The best way to avoid this scenario is to try to reduce the amount of data you use. One way you can do this while using the Opera browser on Android, is to enable the data saving mode.
Opera’s data saving mode reduces the amount of data you download, by proxying certain data types through its servers and compressing them before sending them on to you. The mode specifically compresses text and images that you download.
Tip: Compression is a method of reducing the amount of data used to store content. Given that most web content is already served in a compressed format you may not see too much of a difference in data usage or may see a degradation in the quality of images.
Opera’s data saving mode does not act as a VPN by securely hiding your IP address or online activities. The feature can, however, affect some location services and some privacy concerns are reasonable, as the feature could allow Opera to track your online activity.
To enable data saving mode, you need to go into Opera’s in-app settings. To be able to access the settings, tap the Opera icon in the bottom-right corner of the app.
Next, tap “Settings” at the bottom of the popup pane to open the in-app settings.
In the settings, “Data savings” is the topmost option. Tap the slider to the “On” position to enable data saving mode.
Tip: Opera’s data saving mode is incompatible with VPNs; a warning will be shown for the VPN built into the browser when the data saving mode is active. your mileage may vary but it’s not recommended that you use the data saving mode with any third-party VPNs.
If you tap anywhere else on the “Data savings” label, you’ll open a details page. This page provides some extra details about what the mode does. The page also shows a graph at the top that shows how much data you’ve saved. On this page, you can also select the quality of images, although this option is only available if the data saving mode is enabled.
