Yeah, that battery widget animation is nice (bubbles up while charging), but I can see it killing the battery.
I also tried out the Notes...it's okay. I like the feature of drawing on the notes with your finger, or choosing to pull up your keyboard to type in a note. However, I didn't see options to go to a previous note. Meaning, if you create one, then create another on top of that one, it appears you have to delete the one on top. Unless I am missing how to switch to different notes. Also, it takes up a lot of screen space.Other note apps are much better.
