Safari Websites can only access location While Using the App, Ask Next Time, or Never—there is no "Always" option like there is for apps.
This means that websites can only track your location while Safari is actively open. Once you close Safari or switch to another app, websites lose access to your location.
This is a privacy safeguard to prevent websites from continuously tracking your location in the background, unlike some apps that may require constant location access for features like real-time navigation or geofencing.
Enabling location services as "Always" for third-party apps can significantly impact your iPhone’s battery life. When an app has continuous access to your location, it can frequently use GPS, Wi-Fi, and cellular data to track your position, leading to increased power consumption.
Some apps, such as navigation or fitness tracking apps, may genuinely need constant location access to function properly. However, many apps request "Always" access unnecessarily, running in the background and consuming battery even when you're not actively using them. See the pic below

To manage battery usage effectively, review which apps have location access by going to Settings → Privacy & Security → Location Services and selecting "While Using the App" instead of "Always" whenever possible. You can also enable "Precise Location" only for apps that truly require it.
Ultimately, the decision is yours, but using location services judiciously can help preserve battery life while maintaining app functionality.
