Unlike in movies, spyware in real life has mostly bad intentions. It’s not a tool used to spy on enemies or the villain on a show. Spyware is malicious software that infiltrates a device of an individual without their knowledge.

Smartphones are the most commonly used device by everyone. In fact, most internet activities, from social media to online searches, happen on a smartphone. However, despite the daily use of smartphones, people spend less time learning how they can protect their devices.

The only time one protects their device is when they become a victim of a cybercrime.

The first step to avoiding spyware attacks is by learning about them. Educating yourself about spyware can help you detect if it’s present. It also gives you the upper hand, as you can keep your devices safe from their attacks.

Unlike other malware, spyware is an extremely dangerous cyber threat. It takes weeks or even a month before one can detect if it is present. They work silently in the background, avoiding ways for it to be detected.

Therefore, it’s better to prevent the threat than trying to salvage your smartphone from the attack.

But before you can keep your smartphone safe, here’s what you need to know if your device gets infected by spyware.

What Does Spyware Do to Your Smartphone?

Spyware often tries to peek at the victim’s data and activities. Often this spyware is unauthorized, making them malicious spyware.

Spyware threats can infiltrate devices by clicking on a malicious website, installing an infected app, or downloading a file. Once the spyware gets access to the device, it can perform various actions. It can monitor the keystroke or keyboard activities. Hence, it sees everything you type, including your password. Or, it can capture the screen or turn on the webcam.

Everything stolen by the cybercriminal will be used by them, or they’ll sell to a third party.

Hackers can steal anything when using a malicious spyware program. It can get your login credentials, PINs, credit and debit card numbers, browsing activity, and email addresses.

You can lose money on your bank or your identity when spyware hackers get access to your information. 

How to Detect Spyware Threats on Smartphones?

Although spyware is good at hiding, sometimes there are some telltale signs of their presence on your device.

Presence of Suspicious Apps

Check on your smartphone’s app and see which one looks new to you. Although the presence or absence of an app is not 100% guaranteed, you still need to check on them.

Some spyware threats that are good at hiding behind other apps are those found on parental control or family tracking software.

Rooted or Jailbroken Smartphones

You can get more apps to your mobile device if you root your Android or jailbreak your iPhone. It gives you the option to install apps outside of your app store.

If your phone is rooted or broken, it allows the installation from unknown sources. If you didn’t root or jailbreak your device, it indicates that something is going on without your permission.

Check your Android device by using the Root Checker app if your phone is rooted. Or, you can go to Settings and check the security if unknown sources have been selected. 

For iPhone users, look for the app Cydia on your phone. The presence of this app indicates that your phone is jailbroken. 

Drains Battery Fast

If you notice a sudden change in your battery life, there could be spyware on your device. Although, you have to check what causes the battery to drain. Remember that smartphone batteries degrade over time, so a slow deterioration might mean there’s a problem with the battery. Or, some apps are power-hungry. You can check that on your smartphone’s settings.

Meanwhile, spyware makes sudden changes. Since it works 24/7, it can drain the battery faster than usual. 


Since spyware threats run in the background 24/7, it can cause overheating of a device. Even when you are not using your phone, spyware can cause your device to heat up.

Together with overheating of your device, there is a slowing down on its performance.

But spyware on your phone is not the only reason why it’s overheating. Some power-hungry apps can cause heating of your device too.

Unusual Messages

Receiving odd messages like codes you don’t understand can be indicative of the presence of spyware. Traditional spyware apps send and communicate via text messages. 

You can also check your outgoing messages. The presence of messages you didn’t send can mean something. Spyware hackers used to send messages to acquire data from the mobile device to their base.

Some spyware can even take a picture, wipe your SD, and do other malicious activities on your phone.

High Data Usage

Smartphones that use a high amount of data can mean something is running in the background. Spyware requires sending information to its base. Therefore, it uses plenty of data and resources of the device.

If you want to be sure the high data usage is caused by spyware, you need to eliminate some factors. Even legitimate apps can consume a lot of data on your device.

For Android users, go to Settings > Network & Internet > Data Usage > Mobile.

For iOS, go to Settings > click Mobile Data.

On both Android and iOS users, you can check on the individual apps and the amount of data they use on your device.
