    Before you did these:

    In my car, I have installed:
    9" touch screen radio
    GPS antenna
    Backup/reverse camera
    alarm system (done by friend).
    Was everything OK with car battery?

    Could be the alarm system or the 9" touch screen radio that is the cause of the problems.

    I do not think any GPS app would cause this problem if the radio is turned off.
    You can also test by turning off the app in setting with "Force Stop" and see if that corrects the problem.
    But I do not think that is the problem if the radio is completely turned off.

    Many ways to troubleshoot a problem.......

    I just check with my brother who is a electronic specialist at "VW" and he said seeing that the battery is very new:

    I installed the new battery in October 2020.
    Take the battery back and have it tested there could be a bad cell in it and it should be under warranty and get replaced.
    Also while you have the car in have the alternator checked if it is still putting out the correct voltage that could be a problem also and not fully charging the battery.

    Also he said:

    I know 10-15 minutes driving the car is not enough for battery to get fully charge by the alternator.
    That is not enough time to charge a battery at all.

    You need to take it out on the highway for a good run not drive around for 10 to 15 mins.
