After 2 weeks of using the 3G version of the Note 8 (GT-N5100), I could say a full battery charge gives me at least 7 hours of actual screen time for a 16-hour stretch for the day, using it for light to medium apps and social network sites. I also do drawing using Adobe Photoshop Touch, Autodesk Sketchbook Ink and Sketchbook Pro.

This is my first tablet as I think its compact size and weight is more ideal than the heavier Note 10.1. I simply love digital drawing with the Note 8. I'm coming from a Note II and the bigger screen just gives me more area for line strokes.

7 hours of actual screen time isn't a wow for me as I do my torrent downloads with my Note II with also the same screen time and be able to change to a fresh battery usually in 12 hours. I just find plugging in the Note 8 in the late afternoon to be confident that it really doesn't die on me for an evening in a cafe.

Some 80% of the charge goes to maintaning the TFT screen! Is this normal for TFT screens to guzzle up that much power? I set my brightness to 30% and even set it to power saving mode. Still the screen is the main battery drainer.

Anyway, I set up this thread in the hopes that people can share how to best optimize the battery with proven sound practices.

Screens are always the main power drain on these type of devices...even your Note II.

My Note II only takes roughly 30% of battery charge usage. I'm guessing AMOLED is just more efficient than TFT screen.

What I noticed... the time shown in battery statistics seems to be wrong.

I was also getting approx. 5 hours on battery according to battery statistics. But this felt wrong for me. So I fully charged my Note 8 -> Usage statistic showed 0 hours. Then I was playing and reading for 2 hours (display always on, no reboots). But statistics where showing something around 1 hour and a few minutes. So don't trust your device.

Also, don't turn your back on them. They are out to kill us.

I got my note 8 about two days ago and the battery life was truly horrible but after a couple of charging cycles it seems to be getting better now I get about five to six hours of screen on time

Screen on time tells only part of the story. Its what you're doing with the screen that matters. Browsing and videos will drain the battery faster than reading a book.
