While it is technically possible for a phone to be hacked when turned off, the risks are relatively low, and the likelihood of an attack occurring is even lower. However, it is essential to remember that phones can still be vulnerable to hacking when turned on, especially if they are not adequately secured.
Mysterious apps, calls, or texts appear: A potential telltale sign that your phone has been hacked is the appearance of new apps that you didn't download, along with spikes in data usage that you can't account for. Likewise, if you see calls in your phone's call log that you didn't make, that's a warning as well.
“If there's a process running from the adversarial side, turning off the phone breaks the chain, even if it's only for the time the phone is off, it certainly frustrates the potential hacker. “It may not fully protect you, but [rebooting] can make things more difficult” for hackers, Nanda said.
The key to this vulnerability lies in the iPhone's low-power mode (LPM) feature. As it turns out, iPhones don't completely shut off when you turn them off or when the battery gets drained. LPM kicks in and allows certain functions, like Bluetooth, near-field communication and ultra wideband, to continue running.
A malware scan finds spyware installed
One of the best ways to determine if your iPhone is hacked is to run a malware scan. Antivirus apps for iOS are quite limited as Apple's operating system does not allow them to access areas of the device where malware typically hides.
Can I remove a hacker by resetting my phone? Yes, you should be able to remove a hacker by doing a factory reset on your phone. Keep in mind that this solution will remove all of your data, including contacts, third-party apps, photos, and other files. You will need to set up your phone entirely from scratch.
Unknown apps have access to camera
When setting up a spy app on your phone, the hacker will sometimes need to grant it permission to access your camera. This allows the app to take photos and videos in the background without you knowing.
How Often Should You Shut Off Your Phone? Experts recommend shutting down your phone at least once a week. After shutting it down, let it rest for a minute or two before starting it back up again. Not only will this help enhance your phone's performance, it is also incredibly beneficial for your battery.
Step 1: Change your passwords
On accounts or devices that contain sensitive information, make sure your password is strong, unique—and not easily guessable. Adding your birthday to your mother's maiden name won't cut it.
To tell if your Android is hacked, look for these signs: Your Android loses battery quickly. You get emails about unfamiliar password resets, account signups, etc. You see calls or text messages that you don't recognize.
If you find apps you haven't downloaded, or calls, texts, and emails that you didn't send, that's a red flag. A hacker may have hijacked your phone to send premium-rate calls or messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.
Mobile devices can run non-stop without issues. Whether you turn them off or not doesn't really matter. You won't damage them. The same thing goes for your computer, except you need to protect it from external risks like power outages and surges.
Keep your phone away from you while you're sleeping. If you get any calls or notifications throughout the night that increase the radio frequency radiation coming from your phone, it'll be far enough away from you that you won't be affected as much.
Switching off your phone for one hour a day also improves your sleep quality, sex life, and gets you out the door faster in the morning. Overusing phones is associated with stress, anxiety, and poor sleep quality, whereas moderate use has health benefits.
Unusually High Data Usage
An unusual surge in the amount of data your phone is consuming can sometimes be a sign spyware is running in the background. The spy app needs to use data to send information back to the perpetrator, so a spike in data usage may indicate foul play.
Check for background apps
A more advanced malicious operator wouldn't use such an obvious tactic, but checking for suspicious background apps on your iOS or Android device — usually by hitting the recent apps button on your phone — is a quick way to identify any issues.
Is it even possible for someone to hack your screen? Yes, a person can hack your screen. This is true about phones, computers, and tablets. If your device has a screen, there is a possibility that it can be hacked.

Due to security restrictions on iOS, it is not possible for any app to scan the system or other apps for malware. Apps are not allowed those kinds of permissions, and for that reason, antivirus software on iOS is not possible. Malwarebytes for iOS version 1 does not - and cannot - scan the device for malware.
“If you run your battery all the way down to zero every once in a while — once a year is fine — it makes the percentage count on your battery more accurate,” says Weins. So once a year, not once a week, power your phone off all the way. And don't let anyone else — not even your IT guy —tell you otherwise.
It's not essential to reboot if your phone is running fine, but we recommend rebooting once a week if you encounter regular glitches or slowdown. To reboot your Android phone manually, hold down the Power button until the power menu pops up and tap Restart.
