Premise, this issue will hardly affect anybody as no one would keep the game running for this long under regular circumstances.
I ran the game for several hours replaying a single daily match fight in order to get more moves. After what I believe is around 10 hours, I started to notice that the x3 speed autofight didn't look as smooth. Turning off autofight did, in fact, confirm that the framerate dropped to about 10 to 15 fps.
I didn't run other apps in background, with the exception of an accessibility option (that usually doesn't result in a slowdown) and of system apps that, obviously, can not be turned off.
Restarting the app fixes the issue.
