Neither the Samsung Galaxy Note 8 nor Galaxy S8 Plus have been confirmed, but it is likely the upcoming smartphones will have a lot in common. Rumors surrounding the Galaxy S8 indicate Samsung will bring a host of new features to the smartphone. Those features may then trickle down to the Galaxy Note 8 later in 2017.

Typically, the Galaxy Note line is considered larger and more powerful than Galaxy S smartphones. However, rumors not only suggest Samsung may release two phablets during its spring launch, the larger device, the Galaxy S8 Plus, may have a 6.2-inch display. The device is expected to be around the same size as the Galaxy Note 7, which had 153.5 x 73.9 x 7.9 mm dimensions and a 3,500 mAh battery.  

While unconfirmed, it is possible the Galaxy Note 8 could be similar to the Galaxy S8 Plus in terms of size and design. One major difference between the Galaxy Note and the Galaxy S8 Plus would likely be the inclusion of an built-in S-Pen on the Galaxy Note 8. This would make the two devices similar to the Galaxy S7 Edge and the Galaxy Note 7.

The Galaxy Galaxy S7 Edge is a 5.5-inch phablet with a 150.9 x 72.6 x 7.7 mm dimensions and a 3,600mAh battery. The Galaxy Note 7 is a 5.7-inch phablet with 153.5 x 73.7 x 7.9 dimensions and a 3,500mAh battery. What is interesting about the devices is the Galaxy Note 7 is slightly larger than the Galaxy S7 Edge, but features a smaller battery. Samsung representative told iDigitalTimes just prior to the Galaxy Note 7 launch that its battery was smaller than the Galaxy S7 Edge battery to make room for the Galaxy Note 7 S-Pen.

If the difference between the Galaxy Note 7 and the Galaxy S7 Edge is any indication, it is possible the Galaxy Note 8 could similarly have a smaller battery than the Galaxy S8 Plus for the same reason.

There are two battery rumors circulating for the Galaxy S8 and Galaxy S8 Plus. One rumor suggests 3,250mAh and 3,750mAh battery capacities for the Galaxy S8 and Galaxy S8 Plus respectively. The other rumor suggests 3,000mAh and 3,500mAh batteries for the devices. Both rumors remain unconfirmed. It is notable that rumors are suggesting the Galaxy S8 Plus may have the same battery capacity as the Galaxy Note 7.    

Some murmurs suggest Galaxy S8 Plus may be a test bed for future Galaxy Note devices. The Galaxy Note 8 could be similar in display size and dimensions to the Galaxy Note 8, with the inclusion of a built in S-Pen.

Samsung similarly tested a design tweak on the Galaxy S7 Edge, giving the device more shallow curves and a thinner frame than previous Edge models, before using the design on the Galaxy Note 7.

Samsung is expected to use its dual-edge curved display as a design feature on all future flagships. Both the Galaxy S8 and Galaxy S8 Plus are expected to have dual-edge curved displays. In the past Samsung has released one flat display device and one curved display device, to give consumers options. But now, the devices be differentiate by size, much like with the iPhone.  

The Galaxy S8 and Galaxy S8 Plus are also expected to feature no home button and thin bezels to create more usable screen real estate for the device. The Galaxy Note 8 will likely also have this design.

While the Galaxy S8 and Galaxy S8 Plus are still expected to release without an S-Pen stylus, rumors suggest Samsung may add stylus compatibility to the devices and offer a sold-separately S-Pen for the devices.
