Delphi 10.3.3
got here Android 10 (also Android 8). Battery Optimization is off . The problem only happens if my Device is on the charger. After approximately 48hrs it dies .
I tried to solve this by waking the device up periodically (after 8hrs) . Today it last sent data to the server at 3:00 , so I thought it is dead. But to my big surprise , it still woke up at 08:00 . Unfortunately after touching the screen , to try to open something . Android forced me to close the app.
Here is the part of the code :
(excuse me for the length, it looks to be long , but is is the bare minimum , I thought I'd include every procedure and function I use in order to perhaps help someone smarter then me see if I am leaking memory or doing something horrible, note : this very same code is NOT crashing or hanging after weeks if Device is not on the charger)

Help would be much appriciated. Thank you for your time.
it looks like I need to check if I am in Interactive mode . If I am not in interactive mode then I must do the Reports Back to the Server less often . 15 Minutes instead of 1 Minutes for example.
And behold I started the App on 31.03.2021 14:02:40 , and it is 06.04.2021 06:11 and is still running . All other Versions with Anonymous Threads etc. all died. Only this one with 15 Minutes between the jobs survived. I've read somewhere that an app is only allowed to execute once in 10 minutes if in Doze mode. But can't seem to recall where . Maybe this was the reason why it was killed after two days when running on a 1 Minute Interval.
The code looks like this :
if isInteractive = true then
SyncPeriod := 1
else
SyncPeriod := 15;
SyncTime:=inireadDt(FilePath+'/Configuration/settings.conf','Tasks','SyncTime');
if MinutesBetween(now,SyncTime) >= SyncPeriod then
begin
if isDeviceIdleMode = false then
begin
BatteryLevel := GetBatteryLevel;
GetWifiStatus;
SendDeviceStatus;
iniwrite(FilePath+'/Configuration/settings.conf','Tasks','SyncTime',now);
end;
end;
