Top Smartphones Of 2015: iPhone 6S Rumored To Join Galaxy S6, HTC One M9, Sony Xperia Z4 In Spring 2015 Release

2014 will come to an end before you know it. It's been a good run and we've seen a lot of exciting new products this year, including the iPhone 6, Samsung Galaxy Note Edge, and the Nexus 6. The flagship smartphones of 2014 boast ever larger screens, faster processors, massive battery life, sharper resolutions, and a whole slew of innovative features. For 2015, we're going to see the smartphone industry push the envelope even further. Let's get right to it:

Apple iPhone 6s: The upcoming iPhone 6S is rumored to arrive in Spring 2015 and will go on sale at the same time as the Apple Watch. We expect the Apple 6s to deliver a number of updates that will allow the device to better sync with Apple's new smartwatch. Details are limited at this time. However, earlier this week, a patent leak revealed a cool new vibration motor that will allow the next iPhone to adjust its center of gravity on its own while falling in mid-air. The device will calculate the iPhone's speed of descent, time to impact, and any degree of spin that it may have before it comes crashing to the ground. Meanwhile, the weight in the vibration motor is capable of countering the spin and controlling the iPhone to land screen-up. Welcome to the new era of active-screen-protection.

Samsung Galaxy S6: You can barely mention the new iPhone 6 without an Android fanboy preparing rebuttles that defend the Samsung Galaxy S5. Now, Android speculators are expecting Samsung to deliver a new Galaxy S6 at the Mobile World Congress during Spring 2015. Expect the upcoming Samsung Galaxy S6 to feature a new metal body like the Galaxy Alpha and Note 4. The upcoming phone isn't expected to grow to much in size and will likely feature a screen between 5 to 5.5 inches. A cutting-edge QuadHD resolution screen will also make the Samsung Galaxy S6 one of the sharpest phones available when it arrives on the market.

HTC One (M9): Following the brilliant success of the HTC One (M8), the upcoming HTC One will most likely feature the brilliant signature HTC One metal unibody design while improving a number of features at the same time. Just like the Samsung Galaxy S6, the HTC One M9 is also rumored to feature a 5.5-inch screen with a vivid QuadHD screen. According to rumors, the upcoming HTC may even have the latest octa-core Snapdragon 810 processor. The HTC One M9 will also feature a 16-megapixel cameral with optical image stabilization. However, HTC may ditch the dual lens design from the M8. Look out for the HTC One M9 in March 2015.

Sony Xperia Z4: Last month, Sony made the shocking announcement of a "turnaround strategy" that will involve staggering changes within the company. Basically, Sony is looking to shrink its TV and smartphone lineup to place more emphasis on its popular Playstation video gaming division. That said, a new Sony Xperia Z4 smartphone is slated to unveil at the Mobile World Congress in Barcelona on March 2015. We expect the Xperia Z4 to continue to deliver a robust phone with top rated waterproofing as well as top tier hardware including a 20+ MP camera with 4K video. Stay tuned as we find out how Sony plans to polish the PS4 Remote Play experience on the Xperia.

OnePlus Two: Last but not least is the best phone that you've never heard of. The current OnePlus One is known as the "Flagship Killer," boasting virtually every conceivable high-end hardware all for just the starting price of $199. However, the only problem with the OnePlus One was its exclusivity (the phone can only be purchased if the buyer has received an invite).

The OnePlus One is the only phone on the list with the open-source OS known as CyanogenMod, based on the Google Android. According to insiders, the OnePlus Two will now feature new Android 5.0 Lollipop software as standard. What's more, the team also vaguely mentioned that the new device will be even more customizable than before and will feature a number of surprises along the way.
