Wow! Duo is killing your battery. Chrome is a battery hog, too but I've never seen stats for Duo. That's what's killing your battery.

Do you have any alternative suggestion for dou and chrome?

Samsung browser is pretty good. As for an alternative to Duo, I can't help yo, sorry, odd I know but I don't use those types of apps.
