There are a few things you can do to determine if someone is tracking your iPhone. One is to check the location history of your phone. If someone has been tracking your location for a long time, they may have turned on Location Services. Another way to determine if someone is tracking your iPhone is to look at their phone’s battery life. If the battery life is low, it means that someone is tracking your iPhone and may be using up the battery in order to do so. Finally, you can try turning off Location Services on your phone and then checking the location history again.
