How it is worked out

Data a day = Σ (hours of each activity × GB an hour) · A month = a day × 30.44

Each activity uses a typical amount per hour: video at the quality you choose, short videos and social media about 0.7 GB, music 0.072 GB, video calls 0.5 GB, and browsing, email and messaging about 0.1 GB.

Reading the result

These are averages; real use depends on the app and its quality settings. If your package keeps running out, the chart shows which activity to cut back on first. Video is nearly always the biggest.
