iPhone 6 vs. Galaxy S5: design

The Samsung Galaxy S5 is rumored to come with a metal casing instead of the usual polycarbonate one.

Samsung Electronics Co. Ltd (LON:BC94) (KRX:005930) has reportedly signed a deal with Catcher, the same company that make casing for the MacBook Air, iPad and HTC One. There have also been reports that Samsung may launch a new line of smartphones called Galaxy F that feature a metal design, while the Galaxy S5 would come in the usual plastic design.

Meanwhile, Apple Inc. (NASDAQ:AAPL) has hardly made any changes in the design of its latest smartphone 5S. But this time, the company is expected to remove the Home button from the iPhone 6, and make the screen work as a TouchID sensor. The redesigned chassis will complement the new security features.

iPhone 6 vs. Galaxy S5: display

Sources told the Wall Street Journal  that Apple Inc. (NASDAQ:AAPL) may finally introduce a large size iPhone 6 with 4.8-inch to 5.7-inch display. The company is trying to compete with phablets from Samsung Electronics Co. Ltd. (LON:BC94) (KRX:005930) and other vendors. There have also been reports of an edge-to-edge screen with view-lock technology that lets users take video footage at different angles. The American tech giant recently invested $578 million in GT Advanced Technologies, which makes sapphire crystal. Reports suggest that the entire screen of the iPhone 6 will be made up of sapphire crystal, which is scratch-proof and tougher than concrete.

So far, Apple Inc. (NASDAQ:AAPL) has used LCD displays in its smartphones. But Cult of Mac reports that the iPhone 6 may feature OLED displays. Moreover, the Cupertino-based company recently won a patent to manufacture a curved display. Experts believe that the iPhone 6 could be the first device from Apple Inc. (NASDAQ:AAPL)’s stable to sport a curved display. Apple Inc. (NASDAQ:AAPL) may also use face detection technology in its next smartphone.

The Samsung Galaxy S5 is rumored to maintain the screen size of its predecessor. The Galaxy S5 is speculated to sport a Super AMOLED, ultra-high definition screen with 4K display. Samsung Electronics Co. Ltd (LON:BC94) (KRX:005930) has already unveiled the curved display with its Galaxy Round, so expectations are high that the Galaxy S5 may also feature curved display.

iPhone 6 vs. Galaxy S5: operating system

The iPhone 6 is rumored to feature iOS 8, the improved version of the current operating system. The iOS 8 is unlikely to be visually different than the iOS 7. But its biggest feature would be Maps, according to KnowYourMobile. In contrast, the Samsung Galaxy S5 is rumored to sport the latest version of Android, which is 4.4 Kit Kat. But there have been reports that Samsung Electronics Co. Ltd. (LON:BC94) (KRX:005930) may use its own operating system Tizen rather than Android.

The iPhone 6 may feature a refocusble Lytro camera that allow you to refocus an image even after the picture has been taken. It’s called the plenoptic technology. Moreover, Apple Inc. (NASDAQ:AAPL) signed a deal with Sony Corp. to purchase camera sensors. The Japanese company produces 12- and 13-MP camera sensors that take much less space without affecting the image quality.

In contrast, the Galaxy S5 is speculated to feature a 16-MP camera with ISOCELL technology that can take better pictures in low-light environments. The Electronic Times News reported that the Galaxy S5 is likely to sport the optical image stabilization (OIS), which is used in LG G2.

The Samsung Galaxy S5 is also rumored to sport a 64-bit Exynos 5430 processor. The Galaxy S5 may come with 4GB RAM to utilize the 64-bit chip at the fullest. ARM recently said that Samsung Electronics Co. Ltd (LON:BC94) (KRX:005930) has placed orders for new chips for its upcoming smartphone. But there is uncertainty over which smartphone the new chips will be used in, because the Korean company launches several devices every year.

iPhone 6 vs. Galaxy S5: battery

Apple Inc. (NASDAQ:AAPL) has consistently increased the battery life of the iPhone by about 10% with each generation. The Cupertino-based company has been aiming for a 24+hours of battery life. That may be possible if the company enhances its processor to improve the battery life. Moreover, Apple Inc. (NASDAQ:AAPL) is speculated to increase the size of its next smartphone, which means the company can pack a larger battery in it. Reports suggest that the iPhone 6 may come with a wireless charger that could charge multiple devices simultaneously.

The Galaxy S5 is speculated to feature a 4000mAh battery, the kind of battery no smartphone has ever seen. Most smartphones come with 2200-2600mAh battery. But Samsung Electronics Co. Ltd. (LON:BC94) (KRX:005930) is working on improving the battery life of its devices.

iPhone 6 vs. Galaxy S5: release date
