Google location( Find my device not accurate).

My Device (Samsung galaxy s8) google location is set to "High Accuracy"

When I look at History in google maps, I do not show some stops and claims car is moving!

I have also a GPS tracking device which is always accurate!!

Now the question is if enabling "High Accuracy" which mixes GPS and Wifi hot spots can indeed cause inaccuracy?

update: By not accurate I mean it does not show some stops I made from point A to B.

  • The Google Maps history is normal... at least since Android 7.0, the deep sleep function can cause this on occasion (my guess, but I have seen this too on a various devices, all 7.0 or newer). But what do you mean by Google Location is not "accurate"? Is it off by 10m, 100m, 100km? – acejavelin Aug 17 '18 at 19:26

Missing out places like that is nothing to do with location accuracy and everything to do with battery life. Every time the phone has to start up a process, get a location fix, and record that position in some database or send it to the cloud, it's running your battery down a teensy bit. This might be OK for an app like Strava where users run it deliberately, and are willing to spend some battery life on getting accurate results, but it's not OK for something that's always running in the background.

For this reason, your location history doesn't actually update very often, so it's very common for arrival or departure times to be inaccurate, or even for it to miss a short visit entirely.

Changing location mode won't affect this. One solution if it's really important to have a good GPS log is to use an app specifically for this purpose. It will run down your battery if you run it for a long period. Another option is to use a dedicated handheld GPS. As a purpose-specific device, it's optimized for just this task, and doesn't have to wake up your whole phone just to record a position.
