Hi! I don't understand why the app uses GPS all the time (GPS icon in status bar), even when not operating/connected to the aircraft in camera view. I've tried to dig a bit using developer tools like adb dumpsys location and adb dumpsys batterystat --daily. It seems like the app is setting up GPS during startup and keeps it running all the time. I would expect GPS only to be used when neccessary, not all the time. As it is now the only way to stop this is to force stop the app each time. Leaving it in the background will drain the battery.
Output from adb tools (edited):

adb shell dumpsys location:

    network dji.go.v4 Request POWER_LOW network requested 1m0s0ms fastest 1m0s0ms
    gps dji.go.v4 Request ACCURACY_FINE gps requested 1m0s0ms fastest 1m0s0ms
    gps dji.go.v4 Request ACCURACY_FINE gps requested 900ms fastest 900ms

adb shell dumpsys batterystats --daily dji.go.v4

  Time on battery: 17m 31s 18ms (100,0%) realtime, 14m 16s 748ms (81,5%) uptime

  Estimated power use (mAh):
    Capacity: 2700, Computed drain: 44.2, actual drain: 0

This is a common problem with the android version, don't expect DJI to address the issue anytime soon (or at all).  As you've said you need to actually force stop the app to ensure your battery isn't drained in the background.

Hi, Thanks for the inquiry. We will check this scenario with our engineers if the problem would be the DJI Go 4 app. Thank you for the support.

How much power does it actually use?
At least, unlike the Apple GPS it is quite accurate, this Android App usually gives me accuracy <3m so I use it before flying to check out the sats. Android GPS App .
Never have any 'Follow Me' issues btw (Running App on a Lenovo Tab 3-8Plus).
Also I never found a need to disable the GPS, the tab has a good battery life
A GPS tracker (for animals) weighs 4grams, the battery lasts 180 hours, so the power requirement is quite small.

Hi, I was able to confirm this with our engineers. You can try to disable the GPS on your Android device under app permission to see if there will be changes. Thank you for the support.
