View or restrict data usage by app
Some apps transfer data in the background; that is, when you're not actually using the app, it may download data
for future reference. Restricting background data usage for individual apps can sometimes be a useful way to reduce
your overall data usage. However, this is a drastic measure that may also affect the app's performance or cause it to
malfunction. Check whether data usage can be restricted from the app's own settings (available from within the
app) before restricting it here.
1. Make sure you're viewing the network for which you want to view or restrict app data usage.
2. Scroll down to find the app whose data usage you want to view.
3. To see more details for an app, touch its name.
4. To stop background data usage for this app, check Restrict background data.
5. Read the message that appears. If you're willing to proceed, click OK.
Advanced data usage settings
Two other settings available from the Menu icon can have dramatic effects, but may sometimes be useful:
Data roaming can result in steep additional charges. However, in some locations this may be the only way to
connect to the Internet.
Restrict background data affects all your apps across all available networks, and may cause some features to
stop working. This is an extreme step that should be used with caution.
Optimize memory usage
You typically don't need to worry about managing apps beyond installing, opening, and using them. But there may
be times when you want to know more about what's happening behind the scenes.
Apps use two kinds of memory: internal storage and RAM. They use internal storage for themselves and any files,
settings, and other data they use. They also use RAM (memory designed for temporary storage and fast access)
when they're running.
Android manages and carefully guards the portion of internal storage where the system, apps, and most data for
those apps are stored, because this area may contain your private information. It's not possible to view this portion
of internal storage when you connect your device to a computer with a USB cable. The other portion of internal
storage, where music, downloaded files, and so on are stored, remains visible for your convenience.
