I've had my Note 9 about a week, but just got my number porting straightened out, so I'm using it pretty hard today. Basically setting it up, and manually adding contacts, my choice. It does seem like the battery is a little weak, compared to my S6. I know this phone has way more processing power, and features, but i realize that I'm really going to have to be aware of what I'm doing, until I see what happens. I'm a huge multi-tasker, and the phone handles everything great, just noticing the battery life, seems like it's going fast. I turned off, and optimized everything I can, and have my brightfitness about 40%. I'll try to update on the issue in a week or so. Only other issue I have, is trying to get used to the rounded edges, while typing. Probably just me, having something different.
