    How to tell if someone is spying on your iPhone

    Wondering how to detect spyware on an iPhone? Let’s learn about iPhone spyware detection, and the most obvious signs to look out for to tell if someone is spying on your iPhone.

    Overheating

    Well-functioning iPhones should not overheat. If your device feels unusually warm or hot, this may indicate someone is spying on your iPhone. Of course, spyware installation is not the only reason for an overheated phone, so don't panic.

    You may just need to learn how to clean up your iPhone, and all devices can also benefit from removing unnecessary junk files and apps.

    Drained battery

    Is your battery constantly dying? Spyware works behind the scenes 24/7 to spy on your digital activity. That's why a rapidly draining battery is a sign of iPhone spyware. Ripping through data is normal if you stream video or play lots of online games, but if your battery’s draining at an unusually fast rate, that could mean you have spyware on your phone.

    Unusual messages

    Are random pop-up messages appearing on your iPhone when you browse? Unsolicited ads might indicate spyware infiltration, as spyware is often bundled with adware. Disruptive messages may also come in the form of text messages, or app notifications if you’ve jailbroken your phone and installed apps from outside the App Store.

    Excessive data usage

    Just as spyware will drain your battery, it will also deplete your data. Spyware uses your own mobile data to send out the information it collects on you. That means that you’re paying to send a stalker, hacker, or unwanted snoop data on your digital activities (and maybe even video and audio footage). If your iPhone is slow for reasons other than extreme data usage, check out our guide to learn how to speed up your iPhone.

    New apps

    Another way for spyware to get on your iPhone is through parents or suspicious partners secretly installing monitoring apps. If you find unknown apps on your phone that you don't remember downloading, that can indicate that someone else has access to your iPhone.

    Any of the above symptoms could mean that iPhone spyware has slipped onto your device. But there may be other, more benign explanations, and ultra-stealthy spyware may not leave an obvious footprint.

    The only way to know for sure if spyware or other malware is on your phone is to use a dedicated cybersecurity tool. Avast One features award-winning threat detection that can flush out even the very latest and most advanced privacy and security threats.

    How to remove spyware from your iPhone

    iPhone spyware removal can be done by updating your software, removing suspicious apps, or performing a factory reset. Because iPhone spyware often stays hidden in an unknown file or discretely installed app, you may have to search hard to find it. A spyware removal tool can help you detect and remove spyware from iPhones as well as other types of devices.

    Update your software

    Some iPhone spy software is effective because of an iOS security flaw. Hackers are always looking for software vulnerabilities to exploit, which Apple regularly fixes via security updates.

    You’ll benefit from these anti-spyware software patches by updating your software to the latest iOS release. An iOS update may also help you remove ransomware from your iPhone (or imitation ransomware, which is more common on iOS).

    To know if you need to update to the latest iOS version look for red notification alerts on the Settings App, General tab, or Software Updates tab.

    Here’s how to update your iPhone to get the latest version of iOS:

    1. Click the Settings app icon.

    2. Scroll down and tap General.

      Screenshot of options within the iPhone Settings app.
    3. Then tap Software Update.

      Software Update option within the General section of an iPhone's Settings app.
    4. To install the software update follow the prompts: Download & Install, Agree to Terms, and Enter Password.

      Agree to Apple's Terms and Conditions of the iOS update in order to install the latest software.

    Remove suspicious apps

    If you see an app on your phone that you didn’t download, that app might be spying on or otherwise recording your activity. You can delete the suspicious app on your iPhone by pressing and holding the app icon. Several options will appear. Tap Remove app (or Delete App, depending on your version of iOS) and confirm by tapping Delete app.

    Each app will offer different choices after you press and hold the app icon to activate settings. But all apps have the Delete App option in red.

    If you have a jailbroken iPhone, you have an increased risk of being exposed to unsafe apps sourced from third-party app stores like Cydia. Jailbreaking your phone and downloading unvetted apps will greatly increase the risk of an iPhone virus infection. Get rid of those shady apps immediately and learn how to remove malware from your iPhone.

    Perform a factory reset

    If you’ve tried the steps above and you can’t get rid of the spyware on your iPhone, try performing a factory reset. A factory reset will erase all data from your device, so back up your phone using iTunes or iCloud before wiping it clean.

    To make sure you completely remove the spyware, you’ll need to restore your phone from a backup created before the spyware was installed. If you use a backup made after that point, your restored phone will still be infected with the same iPhone spyware app. There’s no point in resetting your phone if you end up reinstalling the same spyware you’re trying to get rid of.

    Here’s how to factory reset your iPhone:

    1. Click Settings, scroll down, and tap General.

    2. Scroll to the bottom, select Reset, and then tap Erase All Content and Settings. Then tap to confirm.

    Options within the General tab of Settings app on iPhone. Reset option for restoring factory settings is at bottom.

    Keep spyware off your iPhone

    After learning how to detect and remove spyware from your iPhone, shore up your defenses with Avast One, a comprehensive security and privacy app to keep your phone secure.

    This lightweight, top-rated, and totally free app goes way beyond antivirus with thorough malware protection, VPN access, and a web shield to protect against dangerous websites and data breaches. Avast One is the easiest way to keep control of your digital life.

    Can someone spy on my iPhone?

    Yes, a partner, parent, or even employer can gain remote, real-time access to your iPhone using spying software. Spyware can track your GPS location, record your keypad inputs such as credit card numbers and passwords, and monitor your calls, texts, app usage, emails, voice, and other personal data.

    iPhone spyware can appear in the following general forms:

    • Typical spyware refers to malicious apps or software installed secretly on your device by a cybercriminal or even a government authority, like in the case of Pegasus spyware. This type of spyware tracks your activity and is usually controlled remotely.

    • iCloud spyware happens when a hacker or other shady person (like a suspicious partner) figures out your iCloud login details and starts snooping on your device.

    • Masque attacks are spyware programs that appear to be normal updates to reputable apps. But once they’re on your device, they begin recording your activity.

    Pegasus spyware on iPhones

    Pegasus spyware targeting iPhone users was developed by the technology firm NSO Group, which specializes in state-sponsored surveillance software. Pegasus shot to prominence in 2021, when Apple sued NSO amid allegations that Pegasus was targeting iPhone users. Further evidence has come to light suggesting that the Jordanian government used Pegasus to target and compromise the devices of lawyers and journalists.

    Pegasus spyware’s ability to conduct remote, zero-click surveillance of iPhones is a potent reminder of the privacy risk that spyware poses to all digital platforms — even iOS devices.

    Why is iPhone spyware so dangerous?

    Spyware is monitoring software that tracks what you do on your phone. iOS spying software is often well-disguised (parental-control apps can function as a form of spyware), which makes it difficult to detect iPhone spyware. Spyware hides on your iPhone, recording your behavior, including your location, passwords, emails, texts, calls, etc.

    Think of everything you do on your iPhone. Now imagine a stalker, hacker, cybercriminal, or even someone you know personally having access to all of it. That’s unsettling, to say the least.

    Spyware can record everything you do on your phone, including your location, passwords, emails, texts, and calls.Spyware can track your location, passwords, emails, texts, calls, and more.

    Spyware comes in many forms depending on the needs of the spy. The target device can be infected with adware that tracks your movements across the web, Trojan malware that poses as something useful but secretly logs your activities, or keyloggers that record what you type.

    Apple has tried to update their security to block spyware, but like all devices, iPhones are still vulnerable. Pegasus spyware was installed through spear phishing attacks and by taking advantage of unknown (zero-day) vulnerabilities in well-known iOS apps. Apple quickly released a security patch, but subsequent versions of the iPhone spyware found other ways to get in.

    Even legitimate apps on the official App Store can be a Trojan horse for spyware, such as Adware Doctor, Exodus, and so-called parental controls apps like mSpy. Other iPhone spyware can come in the form of location-tracking apps that tell you where your friends and family are, like Life360 and similar apps. If someone uses a tracking app to monitor your activity surreptitiously, that can be a form of spyware.

    How to protect your iPhone from spyware

    To ensure spyware stays off your iPhone, follow these basic steps to avoid infection and protect yourself from spyware infiltration.

    Secure your phone against physical access

Use long and unique passwords for all your accounts and two-factor authentication to secure your personal data. Protect your device with a secure PIN or Touch ID and Face ID, depending on which iPhone model you have.

    FAQs

    What is spyware?

    Spyware is a form of malware used by hackers to spy on people while they use their computers and phones. Lurking silently in the background, spyware is designed to collect sensitive data such as your browsing activity, login credential, and credit card numbers and bank details,  which may then be sold to third-parties or used to commit further cybercrimes.

    Can spyware be removed?

    A dedicated security app with a spyware removal tool can remove spyware from your iPhone and wipe other malware from your iPhone too.  Updating iOS and removing any unknown or suspicious apps will also help to secure your phone.

    Does a factory reset remove spyware?

    Restoring your iPhone to its factory settings will wipe it completely clean, removing spyware and other malware in the process. But unless you backed up your iPhone prior to the infection, a factory reset will result in all your data being lost. Performing a factory reset is a last-resort, and not a substitute for a malware removal tool if you think your phone may have been hacked.

    What is the best app to detect and remove spyware on an iPhone?

    Avast Mobile Security for iOS is designed to guard against the full range of device-specific malware and other threat types, making it one of the best free antivirus apps for iPhone.

    Can someone hack your phone camera?

    Once spyware has infected a phone, it can be used to access all device features — including the camera. To prevent hackers spying on you, protect your iPhone with free iOS security, and set up a VPN to encrypt your internet connection. Using a VPN on your PC or any other devices linked to your phone, as well as taking extra precautions on public Wi-Fi will also help to keep you safe.

    Can iPhone spying software be installed remotely?

    Hackers don’t need to be physically present to sneak spyware onto your phone — it can be installed remotely via malicious apps, links, or scareware downloads. That’s why taking precautions to help you stay safe online is so important. Always check if websites are safe, beware of fake apps, don’t click on unknown or suspicious links, and protect yourself with a top-rated privacy and security app.

    Can iPhones get viruses?

    iPhones can’t get viruses because iPhone viruses don’t exist, but they are still susceptible to other threats. That’s why it’s important to use an iOS security app to detect and remove ransomware, spyware, and other malware. And unlike iPhones, Mac computers can get viruses and other malware infections, but they are relatively rare.
