How can I change the data usage cycle for Mobile data?
The mobile data cycle (Settings -> Data usage) looks quite arbitrary. Since I have changed my data plan, now the new cycle should start at the first day of the month instead of the 6th.
How can I change the begin of a data cycle? I cannot seem to find some edit button, though I vaguely remember seeing it at the Data usage cycle menu.
Affected versions: Android 4.0, 4.2.2, 4.3.1.
Changing the starting day for Mobile data is indeed non-obvious. You need to enable the mobile data connection (2G/3G) before the options are available:
TURN OFF WIFI First.
- Enable Mobile data.
- Exit the Data usage settings app.
- Tap the spinner below the Set mobile data limit checkbox.
- Tap Change cycle....
- Change Date of each month (I prefer the first day of the month,
- Hit Set.
- Undo Mobile data if necessary (e.g. if on Wi-Fi).
The option _Change cycle_ may appear after selecting the _set mobile data limit_ in the dropdown with dates.
The cycle length changing feature is in roadmap https://code.google.com/p/android/issues/detail?id=23676
Even in Android 6.0, you have to turn on mobile data before you see the option to change the cycle.
@Lekensteyn, What Android version is this? Re "spinner below the Set mobile data limit checkbox"; Meaning?
@Pacerier It probably applied to Android 4.x (see question). The "spinner" referred to a "drop down" menu where you could select the time range (and the *Change cycle* option). With Android 8.1 (Pixel 2), there is a *Billing cycle* option within the *Data usage* menu (which is visible, independent of whether mobile data is enabled or not).
