How much data web browsing and email really use
This is the baseline every other guide in the set is measured against. A text article costs almost nothing; a news homepage stuffed with images and autoplay video is another matter entirely.
Kurz erklärt
- An hour of ordinary browsing uses roughly 50–150 MB, depending entirely on how image and video heavy the sites you visit are.
- Email is about the lightest thing on your phone at roughly 20–75 KB a message, until a photo attachment jumps it to roughly 2–5 MB in one step.
- One news homepage costs about as much as reading three to five plain text articles end to end.

Häufige Fragen
Does incognito mode save data?+
The opposite, slightly. Incognito does not keep a cache between sessions, so every revisit re-downloads the images and fonts. It exists for privacy, not for saving data.
Why does email use data even when I am not reading it?+
Because the app is syncing in the background: new headers, the bodies of messages you have not opened, and sometimes attachments fetched in advance so they are ready. Switching from push to an hourly fetch cuts that noticeably, and you will barely notice the difference.
How much of a 7-day plan should I set aside for browsing and email?+
For an hour of browsing a day plus normal email, roughly 500 MB to 1.5 GB is enough. If you are answering work mail with attachments daily, or booking accommodation as you go, budget roughly 2 GB. Put your own numbers into the data calculator to see the trip as a whole.
If I am nearly out of data, what should I do first?+
In order of payoff: kill autoplay video, read articles in Reader view, move email to an interval fetch, and turn off background refresh for apps you are not using. Four changes, under five minutes, and they stretch what is left by days.
