Rapid Battery Drain
When using a phone, if you notice that the battery is draining quickly and the usage time is shorter than before, be cautious as spyware often uses a lot of resources on smartphones to collect data, GPS location information, and record user actions. This monitoring can even occur whenever the phone’s screen is turned on, causing the device to quickly run out of battery.
However, for smartphones with poor battery life compared to the average of the product line, further investigation is needed. Sometimes sudden battery drainage can be due to spyware, but it can also be because you have downloaded too many unnecessary apps, causing the battery capacity to decrease gradually over time.
Data Usage Depletion
If you are not downloading a lot of apps but the phone’s memory is full, you need to check it. Usually, spy apps continuously update and send data to attackers. This definitely consumes a lot of data, and if you notice that your 3G/4G data package is depleting faster than normal, it is possible that your device is being tracked. Not to mention the risk of information leakage, being installed with eavesdropping programs which will directly impact your wallet due to high 3G/4G costs.
Signs of a Tracked Phone
Sluggish Performance and Overheating
If you have recently noticed that your phone is operating slowly and frequently overheating, this can also be a suspicious sign. This could be due to a program recording user behavior and sending it to a remote server, which then occupies the resources of the smartphone. Installing monitoring software makes the device run slowly, even causing it to freeze. As a result, the phone may get warmer, abnormally warm even when not in use.
Unusual Sounds
If you feel that your phone often produces strange sounds, especially during a call, especially when the call starts or when the other person picks up, it is highly likely that the call is being recorded. This is because recording apps will create background noise when in operation.
Signs of a Tracked Phone
In addition, strange sounds can also occur when the user does not touch the phone and the screen is still off. You may also hear echoes, regular tapping sounds even at very low volume… At this time, your phone may be activating the microphone to record sounds from the environment or search for certain signals.
