Galaxy S6 :: Location History And Possible Battery Drain

First of all, I know a lot of people who only has Location on all the time just for their Weather widgets and apps to refresh your weather information, you don't need your Actual Location to have that, you can simply turn that off on the weather app or widget and enter your city or cities manually, it will give you the same information the only difference is that it will not ping your location all the time to do it.

I have tested all settings and I have found that the one that does the job while preserve the battery life the most is the Wifi and Cell signal only option, in other phones it's called Power Saving Mode. I've been using this option all the time for the past couple of months and it really uses very low battery, barely noticeable, this way I keep my location on to be able to use the locate device and other location services. I only change to high accuracy (GPS, WIFi and Cell) for my daily 5k runs or if I need to use Google maps or any other Maps apps. There are people who use GPS only but I've noticed that it increases (obviously) the gpsd service in my battery stats and it drains battery a lot more than Power saving Mode.

Location History is not needed for the Location Services to work, this is just a Google Service to enable other features. Take a look at this information. Google’s Location History is Still Recording Your Every Move.

Until mid April, when we had 2 separate options, Location reporting and Location History, I had location history on but Reporting off as it was besides the Screen, the number 1 battery drainer on Android, and I frankly didn't want to be "reporting" Google all my moves, but now that they incorporated both into just one setting, I just prefer to turn it off.
