Common Mistakes to Avoid

Using a single heavy day as the daily average

Fix: A day of binge-watching does not represent your typical usage. Track your data over a full week, then divide by 7 to get a realistic daily average.

Forgetting that Wi-Fi usage often does not count

Fix: Most mobile plans only count cellular data, not Wi-Fi. If your daily figure includes Wi-Fi streaming, your actual cellular usage (and bill) will be much lower.

Ignoring background app data

Fix: Apps like cloud backups, photo syncing, and social media auto-play videos use data even when you are not actively using the phone. Check your phone's data usage breakdown to include these.
