Note 5 consume so many power to run software. You need powerbank to keep charged, This is most of common issue with all Android phones. Phone like Moto are claiming high performance for battery, but still they need twice charging for same.
This is epic. I guess you need to understand the limitation. I know even if you get 100GB space than also you keep complaining!!
Bro this is mobile not computer where you install as much as you can. Also lots of Apps make mobile slow and again you start complaining about process.
