What are important battery usage and privacy considerations when continuously tracking a user's own real time location in the background, such as for a genuine fitness tracking app or a delivery driver app?

Continuously tracking a user's own real time location, particularly while your app is genuinely running in the background, can meaningfully and quite noticeably drain a device's own battery life considerably faster if not properly and carefully configured, and important considerations include using a genuinely appropriate location accuracy setting rather than always defaulting to the highest possible precision when it is genuinely not actually needed, properly stopping location tracking entirely the moment it is genuinely no longer actually needed, and being genuinely fully transparent with users about precisely why and exactly when their own location is actually being tracked, since both platforms genuinely require a clear specific justification for requesting background location access, and users are understandably quite genuinely sensitive about this particular kind of ongoing privacy concern.
