5 technical terms every smartphone user should know

Technology shouldn’t be confusing or intimidating, especially when most of us are simply trying to use our phones to stay connected, informed and safe.

The problem is that modern devices use terms that sound complicated, even when the concepts are actually quite simple. Understanding just a few of these everyday phrases can make a big difference in how confidently you use your phone.

Here are five key phone terms you’ll see frequently, along with what they really mean.

HOW TO HELP OLDER RELATIVES WITH TECHNOLOGY DURING THE VACATIONS

1) Background permissions

This refers to what an app can do when you’re not actively using it. Some apps continue to run behind the scenes, checking your location, updating content, or connecting to the Internet, even after you’ve closed them.

Why it is important: If an app has background permission, it can: use more battery, use more data, track your location, or run when you’re not using it.

Examples:

• A weather app that checks your location every hour
• A fitness app that reads your steps even when closed
• A shopping app that accesses data when it shouldn’t

Where to check this on your phone:

On iPhone:

• Gonna Settings
• Tap Privacy and security
• Choose Location, microphone or camera services
• Review which apps have access and configure them to While using the app rather Alwaysor toggle permissions completely turned off if the app doesn’t need that background access.

On Android:

YesSettings may vary depending on the manufacturer of your Android phone.

• Open Settings
• Tap Security and Privacy
• Click More privacy settings
• Tap Permissions manager
• Select a category like Location either Camera

Set the access level of each application to Allow only while using the app, ask every time either Denydepending on what you really need to run.

2) Automatically join networks

Your phone remembers Wi-Fi networks you’ve connected to before, such as stores, gyms, hotels, airports, or even an old home router, and automatically reconnects whenever it detects them again. The problem is that scammers can create similar networks with the same name, tricking your phone into joining without you realizing it.

Why it is important: Autojoining saves data and speeds things up, but it also removes your control. Your phone could silently connect to networks you no longer trust or to fake access points designed to steal logins, read unencrypted traffic, or inject malicious content. Turning off auto-joining in places you don’t use often keeps you safer from these silent, high-risk connections.

Examples:

• Your phone reconnects to “airport Wi-Fi” months later
• You join a coffee shop’s network once and your phone keeps connecting every time you pass
• A fake “Starbucks Wi-Fi” network tricks devices into joining automatically

How to manage auto join:

On iPhone:

• Gonna Settings
• Tap wifi
• Touch the (Yo) next to a network
• Deactivate Join automatically to stop automatic connections while keeping the network available for future use, such as gyms, cafes, hotels and airports or choose Forget this network if you want it to disappear completely.

On Android:

YesSettings may vary depending on the manufacturer of your Android phone.

• Open Settings
• Tap Network and Internet
• Tap Internet
• Touch the gear next to the wifi network
• Turn off Automatic connection (either Automatic reconnection on Samsung) to stop automatic connections while still keeping the network available when you choose to join it manually.

3) Push notifications

These are the pop-up alerts or banners you receive from apps, even when those apps are closed. Some notifications are useful (messages, alerts, reminders). Others simply bombard you with ads or updates that you don’t need.

Why it is important: Push notifications may keep you informed, but they also distract you, drain your battery, expose personal details on the lock screen, and give apps a way to lure you back in with constant ads or engagement tactics. Managing them reduces noise and limits the access apps have to your attention and data.

Examples:

• Bank fraud alerts
• Weather warnings
• Sale notifications from a shopping app
• Games that try to make you come back

How to manage push notifications:

On iPhone:

• Gonna Settings
• Tap Notifications
• Scroll through applications one by one
• Deactivate Allow notifications for anything you don’t want

On Android:

YesSettings may vary depending on your Android phone manufacturer

• Open Settings
• Tap Notifications
• Tap App notifications
• Disable alerts for applications you no longer want to know about

4) Security updates

These are small software updates designed specifically to fix vulnerabilities that could be exploited by scammers or hackers. They don’t add new features; They close holes. Skipping security updates leaves your device exposed. They run quickly, often in the background, and keep your phone protected from the latest threats.

Why it is important: Security updates fix weaknesses before attackers can use them, and delaying them gives hackers more time to attack your device. Installing them quickly helps block malware, stop data theft, and keep your phone safe from new exploits that emerge every month.

Examples:
Patches that solve a bug in your browser
Updates that prevent malware from working
Protection against new phishing techniques

Where to find security updates:

On iPhone

• Gonna Settings
• Tap General
• Tap Software update
• Install any updates availableincluding Security Responses and System Files if they appear

On Android

YesSettings may vary depending on the manufacturer of your Android phone.

• Open Settings
• Tap Security and Privacy
• Tap Security, system and updates update either Updates
• Tap Security update
• check if new patches

Click Install now either Schedule installation

5) App Refresh (also known as Background App Refresh)

This is when apps update their content even when you’re not using them, updating news, updating emails, receiving notifications, or syncing data. It keeps apps “up to date”, but it also consumes more battery and uses more mobile data.

Why it is important: Refreshing apps in the background can silently drain your battery, use mobile data, and allow apps to run more frequently than necessary. Limiting it gives you more control over what apps do behind the scenes and reduces unnecessary tracking, resource usage, and surprise data charges.

Examples:

• A news app that updates headlines every few minutes
• Continuous email synchronization
• A social media app is loading new posts in the background.

How to manage app update:

On iPhone

• Gonna Settings
• Tap General
• Tap Background app refresh
• Click Background app refresh again
• turn it completely turned off to stop all background activity, or choose specific applications you want to allow the update.
