TECH SAFETY
Signs Your Phone May Be Monitored
How to Use This Guide
This page outlines possible signs that someone may be monitoring your phone. None of these signs alone confirm monitoring, but patterns can be useful information for planning next steps.
Monitoring can happen through device access, installed apps, account access, or shared services. These checklists are for general awareness, not for confirming or disproving surveillance.
Strange Battery Use
Unusual battery behavior can sometimes indicate hidden activity on a device.
- Battery drains much faster than usual, even with similar use.
- Battery percentage drops suddenly without active use.
- Phone stays on low battery despite being charged as usual.
- Battery life changed noticeably after a specific event (e.g., someone “fixing” or “updating” your phone).
- Battery usage report shows apps using power that you do not recognize.
What You Can Check
- Open your phone’s battery or power settings and review:
- Which apps are using the most battery.
- Whether background usage seems unusually high.
- Notice if battery drain happens at particular times, such as:
- After certain messages or calls.
- When you are away from the abuser.
Unfamiliar Apps
Some monitoring involves installing apps that track location, messages, or activity. These apps may try to look harmless or hide.
Possible Warning Signs
- Apps you do not remember installing, especially:
- “Device admin” tools or “phone manager” apps.
- “Security,” “tracking,” “family safety,” or “backup” apps you did not set up.
- Apps with generic names (e.g., “System Service,” “Update Service”).
- Apps with permissions that do not match their purpose (e.g., a simple game with access to SMS, microphone, or location).
- Apps installed shortly after someone else had your phone.
- Apps set as “device administrator” or with special access that you did not approve.
What You Can Check
- Look through:
- All apps in your app drawer or home screens.
- Installed apps list in your phone settings.
- Review app permissions in settings:
- Which apps can access location.
- Which apps can access microphone and camera.
- Which apps can read SMS or call logs.
- Note suspicious apps on paper or a safe device before making any changes.
If you suspect monitoring and it may be unsafe if the abuser notices changes, consider leaving suspicious apps in place until you have a safety plan and possibly a safer device.
Device Heating
Some monitoring tools run constantly in the background, which can make the device work harder.
Possible Warning Signs
- Phone feels warm or hot even when:
- You are not using it.
- Only simple apps (texts, basic browsing) are open.
- Phone heats up quickly after turning on mobile data, Wi-Fi, or GPS.
- Phone is warm after sitting idle in a bag or on a table.
What You Can Check
- Check running apps or “recent apps” and close anything you are not using.
- Check data usage in settings:
- Look for apps using large amounts of data in the background.
- Notice if heating lines up with specific times, places, or interactions.
Account Access Logs
Even if your phone itself is not altered, someone can monitor through your online accounts if they have your passwords or access.
Where Monitoring May Happen
- Email accounts (e.g., seeing password resets, location alerts).
- Cloud backup accounts that store photos, messages, or device data.
- Messaging apps with “linked devices” or “web” access options.
- Location-sharing services or “find my device” tools.
What You Can Check
- Recent activity or “security” sections in your accounts:
- Logins from devices or locations you do not recognize.
- New devices added that you did not approve.
- Lists of “connected devices” in:
- Messaging apps (e.g., web/desktop sessions).
- Cloud storage or photo backup apps.
- Whether location sharing is turned on with people or accounts you did not choose.
If changing passwords or logging out devices might alert the abuser, you can consider using a different, safer device for sensitive searches or communication instead of changing everything on the monitored phone.
Other Signs to Note
Some patterns may suggest someone has direct or indirect access to your phone or accounts.
- The abuser:
- Knows details about calls, texts, or locations that you did not tell them.
- Mentions things you only wrote in messages or stored in notes.
- Insists on “fixing,” “updating,” or “setting up” your phone, then keeps the password or PIN.
- Settings change without explanation (e.g., Bluetooth, GPS, unknown “profiles” or “device management” entries).
- Text messages appear read when you have not opened them.
- Unusual sounds, clicks, or echoes on calls combined with other signs listed here.
When NOT to Confront the Abuser
Confronting someone about suspected monitoring can increase their control or risk of retaliation. It can also lead them to change tactics in ways that are harder to detect.
Situations Where Confronting May Be Risky
- If the abuser has a history of:
- Anger when questioned.
- Retaliation when you set boundaries.
- Destroying or taking devices.
- If the abuser:
- Pays for your phone plan or account.
- Controls the phone account, cloud account, or app store login.
- Often demands passwords or unlock codes.
- If you rely on the current device for:
- Contact with children, work, or essential services.
- Transportation, banking, or healthcare access.
- If you do not yet have:
- A backup or safer device.
- Alternative ways to communicate if the phone is taken or disabled.
Options Instead of Confronting
- Use the possibly monitored phone only for low-risk communication and information.
- Use a different device (friend’s phone, work device, library computer) for:
- Researching safety information.
- Changing passwords or checking security logs.
- Gradually gather information:
- Write down suspicious apps, devices, or account activity in a safe place.
- Note dates and times patterns occur.
- Develop a safety plan for technology changes, possibly using resources or advocates found through listings at DV.Support.
Planning Next Steps
If you notice several of these signs together, you may choose to:
- Assume the phone might be monitored and adjust what you say, search, or store on it.
- Make a list of:
- Accounts to review later from a safer device.
- Contacts you might need to reach if your phone becomes unavailable.
- Consider obtaining a separate device or SIM card that the abuser does not know about, if that is safe and practical.
Removing apps, changing passwords, or resetting the phone can be helpful, but may alert the person monitoring. It can be useful to think through timing, access to another device, and any supports you may want to involve before making major changes.
