Microsoft has been maintaining a low-key about its upcoming event in New York next month, but details of the new products are already out in the open. One of the most highlighted devices set for release next month is the long rumoured Surface Pro 4.

The unannounced 2-in-1 tablet has made several rounds in the past and is expected to come with incremental upgrades over the current Surface Pro 3. While nothing is official yet, rumours have outlined the possible specs said to debut in the new hybrid. Based on those, we have lined up key feature upgrades over Surface Pro 3.

Display

Microsoft is expected to release Surface Pro 4 in two screen sizes. One variant will feature the same 12-inch display like its predecessor, while the other model will ship with a larger 13 or 14-inch screen. With the larger tablet, Microsoft is aiming at business workers who can transform the Surface Pro 4 into a laptop and easily perform multiple tasks using split-screen.

Processor

Taking a dip under the hood, Microsoft is said to use Intel's fifth-gen Skylake processor with Core i3, Core i5 and Core i7 configurations for Surface Pro 4. This will help the company restore the lost faith of consumers in the Surface Pro lineup. The new processor will improve the performance and efficiency of the device.

Surface Pro 3 was criticised for overheating issues, but the upcoming tablet will overcome that.

Battery

Microsoft Surface Pro 4 will individually overcome the shortcomings of Surface Pro 3. Short battery life was one of the major concerns. According to Business News Daily, Surface Pro 3 lasted for about 7 hours and 27 minutes in custom battery life test.

However, Surface Pro 4 will significantly improve the battery life by adding few more hours on the pack. Use of advanced Skylake processors will also contribute fairly towards a better optimisation of the tablet, resulting in a few extra hours of battery life.

Windows 10

It is common knowledge that Windows 10 will power a wide range of upcoming Microsoft mobile devices this year. The official rollout Windows 10 for mobile is yet to begin and the software giant will release the new software on upcoming Microsoft Surface Pro 4, Lumia 950 and Lumia 950XL.

According to Business News Daily, Windows 10 on Surface Pro 4 will pack tablet and desktop mode, which will be activated when docked to a keyboard. Several new additions, such as full-screen apps, touch-friendly UI and multitasking feature will enhance the usability of the new 2-in-1 tablet.

Improved Stylus

According to a Business News Daily report, the Surface Pro 4 will pack a similar N-Trig stylus like in the Surface Pro 3 with advanced pressure sensitivity. Thanks to Windows 10, the stylus pen will get new functionalities, such as taking screenshot, annotate it and share with others instantly.

Microsoft's event is scheduled for 19 October, where more official details about Surface Pro 4 will emerge.
