VietNamNet Bridge – Smart phone users nowadays tend to demand “big, powerful, long-lasting phones”. “Big” means “large screen”, while “powerful” means “high speed processing unit” and “long-lasting” means the powerful battery which allows to make long conversations.

How big is enough?

When iPhone 2G with 3.5 inch screen appeared on the Vietnamese market, it caught the special attention from hi-tech connoisseurs, because the product has a much larger screen comparing with other kinds of products available at that time on the market which only had less than 3 inch screens.

The demand for large screen phones has become bigger over the last two years. Smart phone users all want the screens to be big enough to satisfy their “visual demand” to serve the entertainment functions, such as watching film clips, playing games or surfing webs.

Dell was considered the first manufacturer who designed 5 inch screen for Dell Streak model. However, the smart phone with the largest screen is Samsung Galaxy Note, which has 5.3 inch screen. Meanwhile, HTC is now still holding the record about the family of smart phones with largest screens.

Hi-tech connoisseurs have shifted to use large screen smart phones, though the screens, of courses, cannot be as big as the screens of tablet PC. Nhat Linh, who lives in Tan Binh district in HCM City, has spent 14 million dong to buy HTC Sensation just because the product has a large screen of 4.3 inch.

“Why do I choose the model? Because the product has a screen large enough to surf on webs, receive and send emails,” he said.

Minh Phuong, a fourth year student of the HCM City University of Technology, feels happy with the second hand Dell Streak he has bought at 7 million dong which has a 5 inch screen. “It is clearly wonderful to play HD games or watch film on 5 inch screen. You can also operate more easily with larger screens,” he said.

Tien Thanh, Director of an electronics import company in HCM City, also said that he has bought a smart phone just because it has large screen, though the product is really expensive – 19 million dong. Meanwhile, Manh Trung, a real estate broker, said that he has bought a 4.65 inch smart phone just because of his poor eyesight, and he always makes mistakes when operating on a small screen phone.

What does it mean by “powerful”?

As for many people, the luxurious appearance of smart phones is enough to show their upper classes in the society. However, the young people, who well understand technologies, prove to be choosier when buying phones. Besides the large screens, they always demand the products with powerful processing units.

“Powerful processing units allow to run all the functions of smart phones in a smoothest way. The more powerful the processing units are, the higher quality the products can bring to users,” said Tran Quoc Hoan, a senior executive of HTC in Vietnam.

Several years ago, 1GHz was considered “wonderful”. However, things have changed greatly. K-Touch W700 is now using duo core processing unit Tegra by Nvidia with the speed of 1.9GHz, HTC Sensation XL is using the one with the speed of 1.5GHz. About tens of products available on the market have the processing units with the speeds of 1GHz and higher.

Long-lasting batteries – the unanswered question

In principle, large screen phones require more regular battery charging. The products with large screens, high processing speed and many features always consume energy. Therefore, users need to turn off unnecessary connections and reduce the brightness of the screens. Most of the smart phones do not have compatible spare batteries. Therefore, the best solution for smart phone users is to bring adapters with themselves.

Though the battery manufacturing technologies have developed strongly recently, the development still cannot catch up with the phone devices.

Galaxy Note now has the capacity of 2500mAh, but this is still cannot satisfy users. Tien Dung from Binh Thanh district in HCM City said he wishes the capacity could be 4000 mAh.
