Set Data Usage Warning Level auf Xiaomi
Once a maximum data limit is configured on a Xiaomi phone, MIUI only tells you when the full amount is used up. Without a separate warning level, there is no early alert, and you can suddenly lose mobile data mid-task.
The warning level lets you define a percentage of your data plan at which MIUI shows a notification. This gives you time to slow down usage or switch to Wi-Fi before the hard limit kicks in.
To set it, go to Tap on Security ➔ Tap on Settings ➔ Tap on Data usage ➔ Tap on Data plan ➔ Tap on Data usage warning level. Then Swipe left or right to set the Data usage warning level and confirm with OK.
A value around 80 percent leaves enough buffer for normal browsing or messaging while still giving a timely warning. Setting it too low, like 50 percent, triggers alerts too early and can be more annoying than useful.
This warning only works if a data plan limit is already set. Without a defined maximum, MIUI has nothing to calculate the percentage against, so the warning level option stays inactive.
