The Note 9 has fast wireless charging capabilities via the Qi standard. The 4000 mAh battery is significantly upgraded from previous Samsung Galaxy phones; as compared to the Samsung Galaxy Note 8 which only had 3300 mAh, which was due to the battery that was in the Note 7. The 4000 mAh was previously seen in only the Active variants of the S7 and S8.
The dual-camera system has one lens with a dual-aperture (f/1.5 and f/2.4) system similar to the S9, but the setup is flipped horizontally rather than vertically, similar to the Note 8's setup.
