Culprit of battery on our note is samsung.android.strokesearch
Force stop it if you are not rooted from going in th e battery stats option..
Or freeze it using titanium backup..if you are rooted...
You will definitely get 20% better battery life....as it was consuming 32%battery on my note 10.1 2014..
However dont kno what this process is related to...
It did not affected my s pen experience any way...
