Apple’s next devil – the iPhone 5 – is expected for October/September release. The new iPad, which debuted on March 7, throws light on what Apple will possibly equip in its iPhone 5. The 4G LTE connectivity in the upcoming iPhone is almost certain.

The new iPad tells us a lot about the upcoming iPhone 5. It would be rather strange if Apple does not bring 4G LTE technology to iPhone 5, after featuring the new iPad with it. 4G technology will give a big boost to mobile data speeds. More bandwidth simply means multi-player online gaming. As better graphic chip is being expected in the upcoming iPhone, it can unleash a whole new world of mobile gaming. Intense graphics games like Counter Strike and Call of Duty may find way to the new iPhone. Quad-core processor chip is also being expected.

There are lots of 4G smartphones available in the market. Apple is always aware of latest technologies but eventually is slow in adaptation. Last year, it was rumored that the upcoming iPhone, which turned out to be iPhone 4S, will be blessed with 4G data speeds. Even in case of iPhone 3G, Apple switched to 3G technology at the time it became increasingly popular in newly releasing phones. But somehow, the tech giant did not accommodate with new trends. Apple fans will be extremely disappointed if the iPhone maker again fails to deliver a 4G compatible iPhone.

With the new iOS 5.1 update, iPhone 4S shows a mysterious 4G icon. We know that iPhone 4S is not 4G compatible and switches to HSPA+ network on AT&T which is faster than the regular 3G network. Mobile downloads speeds on LTE network can go as high as 15 Mbps, while 3G data speeds are even below 2 Mbps. Verizon says that its 4G data speeds can reach between 5 Mbps to 12 Mbps. Download speed on iPhone 4S with iOS 5.1 can go above 2Mbps level, but still it is far below 4G standards.

Battery life is of most concern in development of iPhone 5. iOS devices are always praised for their excellent battery life. But, LTE-enabled smartphones have gained a bad rep for poor battery life. In the whole, 4G Android smartphone lineup, Droid Razr Maxx is the only device that impresses buyers in terms of battery life. The new iPad is 4G-compatible and gives same battery life as iPad 2. But the battery is bigger, making the device slightly thicker than its predecessors. Designing a battery efficient 4G smartphone with sleek design is a challenge for any smartphone manufacturer. But, Apple is going to pack iPhone 5 with a better battery. And, it will be a great achievement if Apple is successful in designing a slim yet battery-efficient iPhone.
