Lately I've been using tiktok to fall asleep (it works pretty well, i think it's because of the looping audio that happens when you get too tired to scroll)<p>However this is the fastest way to wake up to a phone with 0% battery. Scrolling while recharging would solve this but is impratical, and so is using another phone for tiktok only.<p>So, what is the best way to get an android phone to just quit all apps and go to sleep when the battery is below 22% or so? TIA
