Yes it is . I left my phone for a hafe hour or so phone was cold . I checked Instagram and YouTube studio for notifications , closed both apps put the phone back down , and it restarted. Bearing in mind I always have Instagram on restrict mode I turned Instagram on optimize yesterday morning prior to yesterday shutdown and restart hadn't happened since December
I've put Instagram back restrict battery in background
I've just got home after been out for 2 hours and not used my phone
