How to Detect Spyware on iPhone

Spyware is an incredibly dangerous software that can result in your identity, payment information, and personal data being stolen.

Instead of using computers for everything, people have transitioned to using their smartphones for many things – online banking, social media, and emailing- just a few that come to mind.

As such, it’s no surprise that hackers now target smartphones. We will teach you how to detect spyware on your iPhone and protect your data.

10 Things That Indicate iPhone Spyware

Before knowing how to detect spyware on your iPhone, this first section will explain some notable indications that your iPhone has spyware.

1. Shorter Battery Life

One tell-tale sign of spyware is that your iPhone’s battery drains much faster than it usually does.

This is a direct result of the spyware constantly running as a background process, requiring more of your iPhone’s resources.

2. iPhone Getting Hot

Again because spyware persistently runs in the background, it requires a constant supply of resources. It won’t take long before this heats your iPhone.

3. Randomly Appearing Apps

Spyware is often covered up by bloatware. If you notice an app you didn’t install and isn’t a part of recent iOS versions, uninstall it immediately.

Although it doesn’t usually remove the spyware, it will prevent the untrusted app from harming your iPhone.

Network carriers have limits on how much data you can use each month, and if there is spyware continuously transmitting your data, this will eat into your data allowance.

You can usually check your data usage on your carrier’s app/website or monitor the built-in iOS feature.

6. Random Restarts

Random restarting could be a sign of damaged hardware or faulty firmware. It can also be because spyware puts too much stress on the device and causes it to crash.

7. Suspicious Texts

Just like how most spyware transmits data across a network, other spyware may send and receive texts without you realizing it.

It may attempt to delete text messages, so be sure to check the messaging app if you suspect spyware is present.

8. Sudden iPhone Problems

Perhaps your iPhone is suddenly and frequently unresponsive or doesn’t connect to your Wi-Fi correctly. Any sudden problems like this can be caused by spyware interfering with the device’s functionality.

9. Background Noise in Phone Calls

Background noise can be because of spyware, but there are a lot of other factors that cause this symptom. iPhones have great audio hardware, so it isn’t common for users to hear background noise when making calls.

10. Individuals Acting Differently

Lastly, if a friend or family member starts acting strangely around you, they could be the culprit, and they may suspect you know there is spyware on your phone.

Furthermore, they may know your iPhone activity and not like what they found out, thus acting differently.
