Hello, my note 4 is just a week old, i'm getting 3.5h of SOT with 21% left, I wanted to ask if this is normal, as seeing other people get like 5-6 hours of SOT. I pretty much didn't used it heavy. I have Greenify installed. I'm with 4.4 Kitkat. Will buying a new battery help or I should ask them to replace the device if possible?
