I have bought the new tab 8.4. The screen size is good and the multi-windows feature is amazing. However, there is a huge battery drain, even if the device is in "sleep" or "power saving" moods. The cause of that is always "android system"! In my nexus 7 (2013) tab, I have never faced this problem, so I think it is the "Samsung bloatware"
My question is: Is there way to reduce this thing?
Through rooting and using Greenify, or similar; can this issue be solved?
please give me some suggestions for this (other that selling the device of course!)
