Risks even when not in use What is happening during smartphone idle time
Have you ever experienced your smartphone's battery draining significantly even though you just left it alone?
You thought you closed the apps and turned off the screen
You're not on any calls and haven't watched any videos
The battery still drains
That might be proof that your smartphone has been running some processes without you knowing
In fact, on many smartphones, even when the screen is off or in sleep mode,
apps can be running in the background
Communications to receive notifications
Updating location information
Sending logs and error information
Uploading data needed for ad optimization
These are called "background processes during idle time"
and happen routinely inside the device
For example, social media apps
regularly check for new messages or reactions
News apps automatically update articles in the morning
Both are convenient features, but
Many people use their phones without realizing these background activities
These background processes consume battery little by little
Even if the screen is off for a long time,
this is one reason why your smartphone's battery drains
Some apps also send location information in the background
What’s more troublesome is that these activities are hard for users to see
Recently, smartphones that can restrict such background activities have appeared
For example, AntiSpyPhone lets users set whether apps can communicate in the background
It also has mechanisms to individually block access to the microphone, camera, location, and more
No matter what smartphone you have, what is needed nowadays is
the perspective of "what happens when you are not using it"
Understanding this is important
Not using it does not equal safety
Just thinking this way might change how you choose and set up your smartphone
The transparency of which apps run, when, and how might be what future smartphones will require
