Strange battery drain or data spikes aren't necessarily a bug. It could be a malicious app secretly tracking your location, habits, and more. These intrusions are often subtle, but there are clear warning signs that your phone is being monitored.
4. Apps asking for permissions they don't need
The clearest sign that an app might be doing something shady is when it asks for permissions that have nothing to do with the app's purpose.
Let’s say you install a flashlight app. Its only real job is to turn on the LED light on your phone. But during setup, it asks for access to your contacts, microphone, and location. That’s a big red flag. Why would a flashlight need to know who you’re talking to or where you are?
This type of abuse is more common than you might think. Some apps ask for broad access to your data just because they can. Sometimes it’s to collect analytics, but sometimes it’s to sell your data to third parties for advertising or profiling.
Before installing a new app, read the permissions carefully. You can also review the app's permissions after installation. Check which apps have access to sensitive features like your location, microphone, and background data. Then revoke access for any apps that don't have a legitimate need. If you wouldn't give your daily schedule to a stranger, don't give it to a free puzzle game.
3. Battery drains faster than usual
Your phone dies by noon even though you haven't changed your usage habits. You don't game, stream, or scroll much, but your battery can't keep up.
This could be a sign that something is running in the background. Tracking apps are often active, sending GPS pings, syncing with servers, or even recording audio—all of which drain your battery.
Check your battery usage stats. If you see an unfamiliar or unused app near the top, it may be doing more than it claims to. Turning off background activity or uninstalling the app entirely can often fix the problem and improve your battery life, too.
2. Location icon pops up for no reason
You're just checking a text message or browsing the internet and suddenly, there's a location icon in your status bar. You're not using maps, you're not calling a car, and you certainly aren't asking for directions.
That random pin icon isn't just a minor annoyance. It's a sign that something is tracking your location. On Android devices, this means an app has pinged your phone's GPS system, and that can be a big red flag.
Sure, some apps, like delivery services or weather, need your location. But you should check to see if the icon appears even when you’re not using anything location-related. Some apps can access GPS without you opening it, allowing them to collect and sell your location data to advertisers. Others collect location data to map your frequent visits and daily habits.
This is why everyone should review their location settings and check which apps can access their phone's GPS. Setting permissions to "Only While Using the App" whenever possible is always a good idea. You can also completely revoke access for apps that don't need your location to function.
For added peace of mind, you can also view a log of apps that have recently accessed your location to better keep an eye out for shady apps.
1. Data usage spikes without apparent cause
You’re not streaming, downloading large files, or updating your apps. Yet your monthly mobile data allowance is disappearing faster than usual. If you’ve ever checked your usage and wondered where your data went, you probably have an app using it in the background.
Tracking apps often send data, including analytics and usage patterns, to remote servers in the background. This data is invisible to you but can silently eat up your data limit.
A smart move is to check your phone settings for data usage by app. If an app like the calculator is using hundreds of megabytes, it’s time to take a closer look. Consider restricting background data or switching the app’s settings to limit network access. Sometimes the best fix is just to delete the app and find a more privacy-friendly alternative. It can be difficult, but it’s worth it in the long run.
Your phone shouldn't feel like it's always watching you. If you notice sudden battery drain or unexpected spikes in data usage, it's not just your imagination. These are signs that your apps may be tracking you more than they should. The good news is that you have control. With a few quick settings changes, you can protect your privacy and still enjoy the apps you love.
