big battery drain after incoming call - infinite sync loop every 2-3 seconds

Element use too match battery.

I check on my server push:

root@im:~# cat /var/log/matrix-synapse/homeserver.log* | grep 'push actions for @progserega:rsprim.ru' | cut -d ' ' -f1 | sort | uniq -c
     13 2019-10-04
     37 2020-09-23
     81 2020-09-24

And sync:

root@im:~# cat /var/log/matrix-synapse/homeserver.log*|grep '@progserega:rsprim.ru' |grep YD201|grep sync|cut -d ' ' -f1 | sort | uniq -c

Yesterday I clear all cache of element (in his menu) - this is stop battery drain.

But today I get incoming voice call. And after that (may be) battery drain come again. I get incoming call on Element-desktop, but element-android still screen on and was showing incoming call splash after call was ended. May be incoming call tell android-element sync every 2-3 seconds?

root@im:~# while /bin/true; do sleep 5; cat /var/log/matrix-synapse/homeserver.log|grep '@progserega:rsprim.ru'| grep 2020-09-26 |grep YD201|grep sync|cut -d ' ' -f1 | sort | uniq -c;done

I open element-android and see “incoming call splash screen”. But call was ended ~1hour ago. I clear “all cache” again, start element-android, wait when first sync is complete and start monitoring server logs again, but today this not help - sync started again and again every ~3 seconds:

root@im:~# while /bin/true; do sleep 5; cat /var/log/matrix-synapse/homeserver.log|grep '@progserega:rsprim.ru'| grep 2020-09-26 |grep YD201|grep sync|cut -d ' ' -f1 | sort | uniq -c;done
