Data Usage

check and manage mobile data use. You can view Wi-Fi data usage as

Data Saver: Enable or disable Data Saver, which prevents apps
from using data connection in the background. Apps you're
currently using can access data, but may do so less frequently
when Data Saver is enabled. You can touch Unrestricted data to
allow some apps to always have data connection access, even
when Data Saver is enabled.

Mobile data: Enable or disable mobile data.

App data usage: Check how much data has been used during a
time cycle, see which apps have been using mobile data, restrict
background data for individual apps, or allow individual apps to
have unrestricted data usage when Data Saver is on.

Data warning & limit: Set data usage time cycle, and set mobile
data warning and limit.

Wi-Fi data usage: View the Wi-Fi usage of apps.
NOTE:

accounting may differ.
