Is there something called: Stamina Mode in 'Power Management?' in Settings on the Galaxy S4 v5.01?

[AC Question]

Am having trouble seeing Coupons on a specific App that notifies people via email of their availability & to tap them to get into App. I was told to check notification settings as well as the Stamina Mode? I can't find the latter??

Welcome to Android Central! Stamina Mode is a power-saving mode on Sony phones, not Samsung. Which app are you using, and what's the exact message that appears?
