Apple is expected to come out with a much larger version of the iPhone that will feature a 5.5 inch display.
This device will primarily be competing against Samsung Galaxy Note 3, as it appears that the company wants to take the war to this segment as well. After having come out in September 2013, the Galaxy Note 3 is also approaching the end of its life-cycle at the top of the Samsung tree. There has been a lot of speculation that the upcoming IFA will see the launch of Galaxy Note 4.
The Galaxy Note 4 will be a device that builds on the success of the Galaxy Note 3 in a number of ways. One of the key ways will be to improve the design, which even with all the care taken by Samsung continues to be criticized. In comparison with premium offerings from other companies, the Galaxy Note 3 does not have the same feel. It relies on plastics too much and this could change slightly on the Galaxy Note 4. Given that the Galaxy Note 3 already weighs in at 168 g, this is unlikely to be a major area of change. Samsung would not want to increase the weight of the phone further.
Another area of the device that will see major changes is display, but not in terms of size. This is expected to remain the same 5.7 inches, but instead of the full HD resolution on the Galaxy Note 3, the Galaxy Note 4 will feature the QHD resolution. The 386 PPI pixel density of Galaxy Note 3 is not the best in the smartphone, but Galaxy Note 4 may lead the way in this regard.
A big change is also expected to come with the processor. Galaxy Note 4 will become the first device to come with a 64-bit processor. Just as the Galaxy Note 3, the device is expected to come in two versions. One will be featuring the Exynos chipset, which is a 64-bit model, while the Snapdragon processor set to be employed in the other version will be the normal 32-bit one. The Snapdragon processor will be from the 805 range compared to the 801 range used in most high-end devices right now.
In fact, but Galaxy Note 3 also relies upon the 801 range Snapdragon processor whereas in some markets it is sold with the 32-bit version of the Exynos processor. Based on the specifications that have leaked, many expect the Snapdragon processor to improve performance of the device by a whopping 40%. This is also due to a slight change in the GPU. The Galaxy Note 4 is expected to use the Adreno 420 GPU with the Exynos model using a Mali GPU.
The RAM in the Galaxy Note 4 is expected to be the same at 3 GB as in the Galaxy Note 3.
Prices of the Galaxy Note 3 have dropped to around $540 for the 32 GB version, but the Galaxy Note 4 could start at $700.
