As science and technology develops rapidly, the traditional cell phone which could only send short messages and make phone calls is not enough for modern society, people are expected to own a mobile phone that can not only communicate with others but as a way of entertainment, this is the reason why smartphones come into being.
Wikipedia gives smartphone a definition as follows: A smartphone is a mobile phone that offers more advanced computing ability and connectivity than a contemporary basic feature phone. As plenty of manufacturers who produce smartphones, there are a lot of models for us to choose from, this is a buying guide for you when you choose a smartphone.
1. Appearance. The first thing you notice is the appearance. Before you buy a smartphone you would have no idea on the color, contour, bar phone or candybar phone, touch-screen or keypads, or both. A pretty-looking mobile phone makes people feel great. Manufactures never stop designing their cell phones with distinctive appearance. But it seems that when one manufacture designs a pretty facade, others would imitate it, just with another brand. But appearance can be deceiving. A practical advice is that besides the looks, compare their screen and keypad. Which screen and keyboard is more comfortable, everyone has his hobbyhorse.
2. Functions. Besides the traditional use of making phone calls and sending SMS (short messages) or MMS (Multimedia Messaging Service), a smartphone also has the following extra functions: GPS, Bluetooth, Multi-media, Wi-Fi, high-pixel Camera, Network and other functions, as we use application programs to expand applies, compatibility to the applications is very important. Frankly speaking, some of the functions maybe useful in our daily life; on the contrary, they may expend the battery power, so my advice is that choose the right one but not the functional one. oppo a53
3. Brand. As the amount of mobile phone users becomes larger and larger, many brands appear; different brands have their own advantages. For example, Nokia is famous for its quality, it has hardly damage if a Nokia mobile phone falls down by carelessness; the designs of Sony Ericsson cell phones are always attractive; and iPhone is fashionable. The five well-known smartphone brands around the world are Nokia (N97, E72, C5, X6, N95, 670…)/BlackBerry (9650, 9630, 8700…)/Motorola (ME600, CILQ, Droid, A1200, V8…)/Apple (iPhone, iPhone3GS, iPhone 4)/HTC (HTC Hero, HTC HD2, HTC Desire…).
4. Battery Life. We feel troubled when we have to charge our mobile phone batteries once a day, maybe twice or more a day. Why? Because smartphone has many functions such as surf the internet, play mobile games, connect Wi-Fi or use Bluetooth which would consume your battery fast. Especially the 3G smartphones, they demand high-capacity battery. Frequently recharging damages the battery. So, if you don’t want to recharge your battery often, choose a large capacity battery. Maybe in the future, external portable power sources will be the standard configuration and solve this problem.
