According to information from China, the new Galaxy Note 9 from Samsung will feature a 4000mAh battery.
As far as the screen is concerned, it will sport a 6.44″ panel. During the past years, the Galaxy Note Series show a gradual increase in the screen size. The screen size started from 5.3″ with the original Galaxy Note, and reached a 6.3″ panel of the Galaxy Note 8. Thus, we suppose that the Galaxy Note 9 will come at the same dimensions.
The fingerprint reader type is not clear yet, as it is not known if it is going to be an in-display one.
