Android - How can I change the data usage cycle for Mobile data?
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,
1
) - Hit Set.
- Undo Mobile data if necessary (e.g. if on Wi-Fi).
For me (CM 12.1), it is still confusing. You have to go under Settings
, Data Usage
and then:
- make sure that both
Data connection
andSet mobile data limit
toggles areON
- below them, there is range of dates dropdown, which you can choose to see data usage of previous months. Click on it, and you will get a list of previous periods.
- now, you have to scroll all the way down through all periods (mine seems to go back all the way down to January 1970 !!!) - below the last one there will be
Change cycle...
option. Click it, and it will allow to change starting date.
