Your phone shares data at night: Here’s how to stop it

NEWYou can now listen to Fox News articles!

If your smartphone stays on your bedside table overnight, it stays busy long after you fall asleep.

Even while it appears idle, your phone continues to send and receive data in the background. Some of that activity is expected. Your device checks for security patches, syncs system settings and keeps essential services running. Other data transfers are far less obvious and far less necessary.

Experts warn that smartphones routinely transmit tracking and advertising signals without you fully realizing it. In many cases, that data includes information that should only be shared with clear and informed consent.

What data your phone sends while you sleep

Your phone is not just charging overnight. It operates in a continuous data loop that generally falls into two categories.

Legitimate system data

This includes updates, crash reports and basic diagnostics. Operating systems rely on this information to fix bugs, improve stability and protect against security threats. In most cases, this data collection is disclosed and configurable.

Tracking and advertising data

This is where concerns grow. Smartphones also transmit location signals, device identifiers, advertising IDs, usage patterns and app behavior data. Companies combine this information to build detailed user profiles and deliver targeted ads that promise higher engagement. The problem is that the line between necessary diagnostics and commercial tracking is often blurry. Many of us never realize how much data flows out of our phones overnight.

What we know about phone tracking today

Independent academic investigations found that some Android devices transmitted data linked to tracking behaviors involving major companies like Meta and Yandex. The research, conducted by teams from IMDEA Networks Institute and European universities, showed that certain apps and services continued communicating with external servers even after users attempted to limit tracking. The researchers observed data flows that could link web activity with app identifiers, raising concerns about how effectively privacy controls were enforced at the system level.

There is also long-standing concern around smartphones appearing to “listen” to conversations. While no public evidence shows that phones actively record private speech for advertising, many users report ads that closely mirror recent conversations. At a minimum, aggressive data collection combined with location, app usage and search history can make these moments feel unsettling.

Despite years of scrutiny, most smartphones still operate this way today. The good news is that you can reduce how much data leaves your device.

How to protect yourself from overnight data sharing

You do not need to give up your smartphone to regain control. Small settings changes can make a real difference.

1) Review app permissions

Start with your installed apps. Focus on those with access to your location, microphone, camera and tracking data. Only allow sensitive permissions while the app is in use. Be especially cautious with apps that run continuously in the background.

How to review app permissions on iPhone

Open Settings
Tap Privacy & Security
Tap Location Services, Microphone, Camera or Tracking
Select an app from the list
Choose While Using the App or Never when available

For tracking controls:

Go to Settings
Click Privacy & Security
Tap Tracking
Turn off Allow Apps to Request to Track

This prevents apps from accessing your advertising identifier and sharing activity across apps and websites.

How to review app permissions on Android

Settings may vary depending on your Android phone’s manufacturer.

Open Settings
Tap Privacy & Security or Security and privacy
Click More privacy settings
Tap Permission Manager
Select Location, Microphone, Camera or Sensors
Tap an app and choose Allow only while using the app or Don’t allow

To review background access:

Go to Settings
Click Apps
Select an app
Tap Mobile data & Wi-Fi
Turn off Background data if the app does not need constant access

This limits silent data transfers when the app is not actively open.

2) Limit background activity

Disabling background activity reduces how often apps sync data when you are not using them. This also limits automatic cloud activity. Keep in mind that this may affect real-time backups or notifications. Weigh the convenience against the privacy trade-off.

How to limit background activity on iPhone

Turn off Background App Refresh

Open Settings
Tap General
Tap Background App Refresh
Tap Background App Refresh at the top
Select Off or Wi-Fi

To disable it for specific apps:

Stay on the Background App Refresh screen
Toggle off apps that do not need to update in the background

This prevents apps from quietly syncing data when they are not open.

How to limit background activity on Android

Settings may vary depending on your Android phone’s manufacturer.

Restrict background data

Open Settings
Tap Apps
Select an app
Tap Mobile data & Wi-Fi
Turn off Background data

Restrict background battery usage

From the app’s settings screen, tap Battery
Select Restricted or Limit background usage

This reduces background syncing and prevents apps from running silently when you are not actively using them.

3) Turn off personalized advertising

Personalized ads rely on device identifiers and activity data collected across apps. Turning this off limits how your behavior is used for ad targeting, even when your phone is idle.

How to turn off personalized ads on iPhone

Open Settings
Tap Privacy & Security
Tap Tracking
Turn off Allow Apps to Request to Track

To limit Apple ads:

Go to Settings
Click Privacy & Security
Tap Apple Advertising
Turn off Personalized Ads

This reduces ad targeting based on your activity within Apple services.

How to turn off personalized ads on Android

Settings may vary depending on your Android phone’s manufacturer.

Open Settings
Tap Privacy & Security or Security and privacy
Click More privacy settings
Tap Ads or Advertising
Tap Delete advertising ID or Opt out of Ads Personalization
Click Delete advertising ID

You can also reset your advertising ID from this menu to break the link between past activity and future ads.

This limits how apps and advertisers track behavior across apps and websites.

4) Consider a VPN

A reputable VPN can help obscure your IP address and reduce certain forms of network-based tracking. It does not stop all data collection, but it adds a layer of protection, especially on shared or public networks.

For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices at Cyberguy.com.

5) Remove your data from broker sites

Even if you lock down your phone, much of your personal information already exists online. Data brokers collect and sell details like your name, address, phone number and browsing behavior.

Using a reputable data removal service can help locate and remove your information from these sites. This reduces how easily advertisers and third parties can link your phone activity to your real identity.

For ongoing protection, these services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

6) Use airplane mode or power off at night

If overnight data sharing concerns you, the simplest option is also the most effective. Turning your phone off or using airplane mode cuts off wireless communication while still allowing alarms to work.

How to turn on airplane mode on iPhone

Open Control Center by swiping down from the top right corner
Tap the airplane icon so it turns orange
Confirm that cellular, Wi Fi and Bluetooth turned off

How to turn on airplane mode on Android

Settings may vary depending on your Android phone’s manufacturer.

Swipe down from the top of the screen to open Quick Settings
Tap the airplane mode icon
Check that mobile data, Wi Fi and Bluetooth are disabled

If you still want Bluetooth for a watch or headphones, you can turn it back on manually after enabling airplane mode. This keeps most background data transfers blocked while you sleep.

Kurt’s key takeaways

Your smartphone works around the clock, even when you do not. Some background data sharing keeps your device secure and functional. Other data collection exists primarily to fuel tracking and advertising. The key is awareness and control. By tightening permissions, limiting background activity and disabling ad personalization, you reduce how much of your personal data leaves your phone while you sleep. Privacy is not about fear. It is about informed choices.

A giant cell tower is going to space this weekend

A giant cell tower is going to space this weekend

This weekend’s scheduled Blue Origin rocket launch is rather momentous. Success would signal an end to SpaceX’s monopoly on reusable orbital launch vehicles, and set up a three-way race to make that “No Service” indicator on your phone disappear forever.

On Sunday morning, Jeff Bezos’ massive New Glenn rocket is scheduled to launch with the first-stage booster that launched and landed on the program’s second mission last November. It’s a critical test, because cost-effective booster reuse is what’s made SpaceX’s Falcon 9 so dominate.

Amazon desperately needs a reusable rocket of its own to accelerate its Leo launches. Without one, it’s only been able to launch 241 Leo satellites, putting it well behind schedule. In that same 12-month time period, SpaceX’s Falcon 9 rocket was able to deploy over 1,500 satellites to its Starlink constellation.

Sunday’s mission will carry AST SpaceMobile’s BlueBird 7 satellite to low Earth orbit. Instead of blanketing the region with thousands of small satellites like Amazon and SpaceX, AST’s plan is to deploy fewer satellites that are much more powerful. Bluebird 7 features a massive 2,400-square-foot phased-array antenna, making it the largest commercial communications array ever deployed in low Earth orbit. It’s essentially a cell tower in space, and will be the second of the company’s “Block 2” next-generation satellites to launch.

The BlueBird 7 is designed to provide 4G and 5G broadband, at speeds exceeding 120 Mbps, to the phones we already carry. AST plans to have 45 to 60 satellites launched by the end of 2026. When AST lights up its service sometime this year, it will be in direct competition with Starlink’s direct-to-cell service, already operating with T-Mobile in the US, and Globalstar, the satellite network snapped up by Amazon that keeps iPhones and Apple Watches communicating in dead zones.

New FBI warning reveals phishing attacks hitting private chats

Cyber expert shares tips to avoid AI phishing scams

Kurt ‘The CyberGuy’ Knutsson shares practical ways to avoid falling victim to AI-generated phishing scams and discusses a report that North Korean agents are posing as I.T. workers to funnel money into the country’s nuclear program.

NEWYou can now listen to Fox News articles!

You probably think your messages are safe. After all, apps like WhatsApp, Signal and Telegram promote strong encryption.

But a new warning from the Cybersecurity and Infrastructure Security Agency and the Federal Bureau of Investigation shows that attackers do not need to break encryption at all.

Instead, they are going after you.

FBI WARNS ABOUT FOREIGN APPS AND YOUR DATA

What the FBI and CISA just revealed

According to the joint advisory, cyber actors tied to Russian intelligence are running large-scale phishing campaigns targeting messaging apps.

These attacks are not random. They have focused on high-value targets like government officials, military personnel and journalists. However, the tactics can easily spread to everyday users.

Here is the key takeaway: Hackers are not cracking the apps themselves. They are tricking people into giving up access.

How these messaging app attacks actually work

This is where it gets interesting and a bit unsettling. Instead of breaking encryption, attackers use phishing to gain control of individual accounts. Once inside, they can:

Read private conversations
Access contact lists
Send messages as if they were you
Launch new scams targeting your contacts

It becomes a chain reaction. One compromised account can quickly lead to many more. In some cases, attackers impersonate trusted contacts. That makes the scam feel real and urgent.

Why encryption is not enough anymore

Encryption still matters. It protects messages as they travel between devices. But here is the problem. If someone logs into your account, they see everything just like you do.

That means even the most secure app cannot protect you if your login gets compromised. This is a shift in how cyberattacks work. The weakest link is no longer the technology. It is human behavior.

Who is at risk from messaging app phishing attacks

While the advisory highlights high-profile targets, the tactics are not limited to them.

If you use messaging apps for:

Personal conversations
Work communication
Sharing sensitive information

You are a potential target. Phishing works because it relies on simple mistakes. A quick tap on the wrong link is often all it takes.

What this means for you

This warning highlights a bigger trend. Cyberattacks are becoming more personal. Instead of attacking systems, hackers are targeting people directly. That makes awareness your strongest defense. The more you understand how these scams work, the harder it becomes for attackers to succeed.

Ways to stay safe from messaging app phishing attacks

You do not need to be a cybersecurity expert to protect yourself. You just need to slow things down and follow a few smart habits.

1) Be skeptical of unexpected messages

If a message feels urgent or out of place, pause. Even if it looks like it came from someone you know.

2) Never click suspicious links

Avoid links sent through messages unless you can verify them independently. Strong antivirus software can help detect suspicious behavior after a compromise. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.

3) Turn on two-factor authentication

Two-factor authentication (2FA) adds a second layer of protection even if your password gets exposed.

4) Watch for login alerts

Many apps notify you when a new device signs in. Do not ignore these warnings.

5) Verify requests in another way

If a contact asks for something unusual, call them or confirm through another channel.

6) Use a data removal service

Limit how much of your personal information is available online. Data removal services work to delete your data from broker sites, making it harder for scammers to target you with convincing phishing messages. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.

7) Keep your device and apps updated

Install updates regularly. Security patches fix vulnerabilities that attackers can exploit after gaining access.

Kurt’s key takeaways

Messaging apps feel private. They feel secure. That sense of comfort is exactly what attackers are counting on. The technology is still strong. The real question is whether your habits are keeping up. So the next time a message pops up that feels slightly off, trust that instinct and take a second look.

YouTube’s mobile app finally lets you share timestamped videos

YouTube is making some changes that might affect how you share videos from the mobile app. From the app, you can finally share videos from a specific timestamp, which will make it easier to point someone to a part of a video you might want them to see while you’re on your phone. However, this change will replace the Clips feature that lets you make a shareable clip from a video.

You’ll still be able to watch any Clips that you’ve already made. But moving forward, “the ability to set an end time or include a custom description when sharing will no longer be available,” YouTube says. The company notes that while clipping is “important way for creators to reach new audiences,” it says that “a number of third-party tools with advanced clipping features and authorized creator programs are now available to do this across different video platforms.”

The company originally introduced the Clips feature in 2021.
