I'm not sure if this will help, but for those that are looking for an app to takes notes, the two I most use are called "Keep Notes" and "Notebook"

Keep Notes is easy to use and is good to make lists of things like shopping lists, expenses and so forth. You can also make entries by writing with your finger or with appropriate pen you can draw on screen with.

Notebook is set up a little differently where you create books that are placed on a grid and you select one to make entries in.

Hope that helps!

One question. How much battery drain overnight when phone is idle?
