Many people blame the network when their daily data finishes early. In practice, a handful of apps are often responsible: video apps that autoplay, apps that back up photos over mobile data and updates that download silently. The good news is that Android shows you where your data goes, and a few settings can save you a lot.
Open Settings → Network & internet → SIMs (or Mobile network) and choose your SIM, then App data usage. You will see a graph and a list of apps ranked by how much data they used in the selected period. On some phones, the path is Settings → Connections → Data usage. Look at the top three apps; that is where the savings are.
In the same screen, set a data warning at, for example, 80 percent of your plan and a data limit if you want mobile data to switch off at a certain level. Set the billing cycle date to match your recharge date, otherwise the counts will not match your plan.
In the Google Play Store settings, choose "Over Wi-Fi only" for app updates. System updates can also be limited to Wi-Fi.
If data seems to finish quickly because pages load slowly and retry, test the connection with a tool such as Speedtest at different times of day. A weak signal can cause repeated loading, which uses more data than you expect.
Does turning off mobile data when I am at home help? Phones prefer Wi-Fi when it is connected, but switching off mobile data prevents accidental use if Wi-Fi drops.
Why does the phone's count differ from my operator's? The operator measures from its network and rounds in its own way, so small differences are normal.
Video apps usually use the most. Setting video quality to a lower level on mobile data can save a lot without much visible change on a small screen. Turn off auto-play of videos in social apps, and download shows over Wi-Fi to watch later.
Divide your monthly data by the days left in the month to get a daily figure. If you have 30 GB for 30 days, that is about 1 GB a day. Check your usage in the evening a few times a week, and adjust if you are going over.
If you keep running out, the plan may not match your needs. Compare plans from your operator, and check whether your home has Wi-Fi that you can use more. Do not buy extra data packs from unknown apps; use your operator's official app or website.
