What are the advantages and disadvantages of BlackBerry 9900?

1. Good call quality; Even if you make a phone call in a noisy street, you can make a clear call without affecting the other party's hearing your voice.

2. The signal is good; This is because it can automatically select the one with good signal quality in GPRS, EDGE and GSM networks, and of course, changing networks will increase power consumption slightly. EDGE is a technical scheme for the transition from GPRS to the third generation mobile communication. GPRS is commonly known as 2.5G, EDGE is commonly known as 2.75g, and 3G is needless to say.

The appearance is ok, thinness has become the mainstream, and it has also become synonymous with sameness. In fact, the appearance of the blackberry for a long time is actually very attractive, after all, the work is there. Moreover, there is an alternative feeling. In the past, even some BlackBerry friends in the forum said that the reason why I chose BlackBerry was that I felt that the mobile phone with a very MAN shape felt very similar, and the more I used it, the more I liked it. And BlackBerry's excellent workmanship is not comparable to Nokia's.

4. Excellent materials and workmanship; Because there are many excellent mobile phones. So it can't be said to be the best. In the sun, the screen is not reflective, and the voice of the call is loud and clear.

As a business mobile phone, all the supports are supported, such as Shenma Bluetooth, Shenma WIFI, software application, basic, navigation key+full keyboard layout, plus rich shortcut keys, accurate input and convenient recording.

6 durable, this has not been verified, it is temporarily added.

Talk about shortcomings:

1. As the most prominent email function of BlackBerry, it has not been supported in China before, but there are business eggs in recent years, which are very expensive. The cheapest 70 yuan/month at present. The service fee is relatively high, and if the company can't reimburse it, the expenditure is still a bit high. It is equal to not using the most awesome function of BlackBerry.

2. The entertainment function is low. In the face of the powerful Android system, BlackBerry as a business entertainment software is very unsatisfactory. In short, it is suitable for business applications.

The battery capacity of 3.9900 is small, and the standby time is painful. The 9900 is equipped with 1GCPU and 1G memory, and the battery capacity is only 1250MA. If you use it a lot (surfing the Internet, chatting on Q, watching multimedia), you won't last for 24 hours, even worse than the old 8700, which can last for 4 days. Other batteries have a slightly smaller capacity.

Personal opinion, I hope it will help you.
