Just got my First Note device! need some tips! topic

Hello guys i just bought myself a brand new Note 4 (N910F) from Germany model.

Its my First Note device, my last device was the s3 i9300 but my motherboard fried up so i decided to move on :)

Can you give me some cool tips to improve my Note expirience?
For example the best apps to use the S pen with?

Best app for taking notes? Or something useful for university?

Tips what to turn off or on?

Tips to save battery life?

Thanks in advance :)
