I am having an issue with Pokemon go where I will set my phone down with the app open accidentally and it will drain my battery to 0 because it keeps the screen from timing out. I have searched high and low on google to try and find this setting but to my dismay it always interprets my question as the literal opposite and shows me results for "how to keep your android screen on". The only relevant question I could find was here, where the answer is either incorrect or out of date. I tested this myself, screen set to 15 second time out works normally on my android home screen but then when I open the app the screen stays on.
Does there exist a setting that changes this?
