Smartphones contain enormous amounts of personal information, including messages, photographs, contacts, location data, financial information and browsing activity.

This is why many people become concerned when their phone suddenly starts behaving strangely.

Could someone be tracking your phone?

There are legitimate reasons a phone may show unusual behaviour, so a single symptom does not prove that someone is monitoring you. However, several warning signs together may deserve attention.

One possible sign is unusually high battery usage.

If your battery suddenly begins draining much faster than normal, check which applications are consuming the most battery.

A badly optimised application, an ageing battery, poor network coverage or heavy use can all cause rapid battery drain. Therefore, battery drain alone should not be treated as proof of surveillance.

Another warning sign is unexplained mobile data usage.

If your phone is consuming significantly more data than usual even though your habits have not changed, check your data usage settings.

Look for applications using data in the background.

An unfamiliar application consuming unusually large amounts of data deserves investigation.

You should also regularly check the applications installed on your phone.

If you discover an application that you do not remember installing, investigate it before removing it.

Some legitimate applications may have been installed by another person who previously used the phone, or they may have been installed as part of another application or system process.

Be particularly cautious with applications that request extensive permissions without an obvious reason.

Location permissions are another area worth checking.

Both Android and iPhone devices allow users to review which applications have access to location information.

If an application that does not need your location has constant access, consider changing its permission.

You should also review which applications can access your microphone, camera, contacts and photographs.

Another important warning sign is unexpected account activity.

If you receive alerts about logins, password changes or new devices that you don’t recognise, take them seriously.

Someone who has obtained access to one of your online accounts may potentially access information without physically having your phone.

Check your Google or Apple account security settings and review devices that are signed into your account.

WhatsApp users should also check their Linked Devices section.

If you see a computer or other device that you do not recognise, remove it and secure your account.

You should also enable two-step verification where available.

Another concern is when your phone suddenly becomes unusually slow or behaves strangely.

However, there are many ordinary explanations for this.

A phone can become slow because of limited storage, ageing hardware, software bugs, background applications or operating-system updates.

Therefore, slow performance does not automatically mean that someone is monitoring you.

Unexpected pop-ups can also be a warning sign, particularly if they appear outside normal applications.

Persistent advertisements, browser redirects or unfamiliar notifications may indicate unwanted software.

If this happens, review recently installed applications and browser permissions.

Keeping your phone’s operating system and applications updated is another important security measure.

Software updates often include security fixes that protect devices against known vulnerabilities.

You should also avoid installing applications from unknown sources unless you fully understand the risks.

Never give your phone’s password or verification codes to someone simply because they claim they need them.

If you suspect that someone has access to your phone, change important passwords from a trusted device and enable two-factor authentication where possible.

You can also review account sessions and remove devices you don’t recognise.

If the problem continues and you are seriously concerned about compromise, consider backing up important information and performing a factory reset.

Before doing this, make sure your important files and contacts are safely backed up.

If the concern involves stalking, harassment or threats, the situation should be treated as a personal safety issue rather than simply a technical problem. Consider seeking appropriate professional or law-enforcement assistance rather than confronting a suspected person yourself.

Most importantly, don’t panic because of one unusual symptom.

A hot phone, fast battery drain or poor performance can have completely ordinary explanations.

The strongest warning signs are usually multiple unexplained changes occurring together, especially unfamiliar applications, unknown account logins, unexpected permissions and devices linked to your accounts.

Your smartphone is effectively a digital key to much of your personal life. Regularly reviewing its security settings can help you identify problems early and protect your information.
