We strongly recommend having WiFi enabled at all times, even if not connected to a known network, to ensure your location is as accurate as possible.
GPS relies on satellites to detect your location and interference can be caused by objects such as buildings and trees. Therefore, if you're stuck inside a building and don't have WiFi enabled, your position may be less accurate.
Enabling WiFi may even improve battery life as GPS can consume a lot of battery if the signal strength is low 🔋.
Pro tip 💡: As mentioned above, your phone doesn't need to connect to any WiFi access points for your position accuracy to be improved.
