As a mobile phone fan, experience tells you that the price around 2000 is the world of domestic mobile phones. At this price, Samsung and HTC are either out of date or change water. Instead of buying a second-rate non-domestic mobile phone, it is better to choose a domestic big brand mobile phone with high cost performance. I recommend several representative models with the same price: 1500. In the price range, I recommend Huawei G700 quad-core 5-inch 720P-p screen 2G RAM8G ROM, support 32G memory card expansion of 8 million 2.4 aperture back-illuminated camera front 1.3 million camera 2 150mah battery, and ensure Huawei's good quality after heavy use in a day. Good experience, thanks to the powerful calculation and storage of 2G RAM, no matter how many tasks there are, there is no pressure. Games and videos have been on the market for some time and have withstood the test of the market. It is recommended to focus on them. If you care about standby power, you must mention Lenovo. I don't know which one you used doesn't operate smoothly. Anyway, my A830, my friend's P770 and P780 are all very good! Recommend Lenovo P780: Quad-core mobile phone with 5-inch 720P HD screen Corning Gorilla glass touch screen1G Ram4g ROM 8 million 2.0 aperture back-illuminated camera 4000mah battery supports OTG function and super touch screen technology. My colleague has been using it all the time, and the shooting effect kills all mobile phones at the same price, with outstanding battery life and ultra-sensitive touch screen technology. Whether it is white gloves worn by traffic police or rubber gloves worn by doctors, you can get in touch with mobile phones smoothly. OTG's function is practical and high-end, and the multimedia expansion capabilities such as mouse, game pad and USB flash drive can be externally connected, leading the mobile phone at the same price. The system runs smoothly, with good operating experience and no jamming phenomenon. In particular, endurance is rare in smart phones. P series focuses on high-end business, and it is recommended to focus on it. At the price of 2000, only high-end quad-core mobile phones, 4.7-inch 720P super retina screen 2G RAM8G ROM and 32G memory card expansion13 million Sony stacked cameras are recommended. 100 pixel camera, just look at these configurations and you will know that it has strong shooting, gaming and multitasking capabilities. The key is that it is also a high-end three-proof mobile phone, which can operate the mobile phone in water, and it is the first to solve the technical problem that the smart phone cannot operate in water. It just went on the market in September, and the price of 1888 is absolutely dominant. It is the most cost-effective three-proof high-end intelligent machine. The specific configuration and evaluation can be Baidu, so I won't go into details. The model is Huawei Glory 3 Outdoor. Some people say OPPO find5 is good. After playing for a few days, the experience was good, the screen and camera were good and the operation was smooth. Personally, I just don't like it because I don't support memory card expansion. The endurance is not so good. 1080P screen and Qualcomm 8064 CPU consume a lot of power, and the power drops rapidly when playing games, so it is essential to charge twice a day. You can pay attention to it, 2499 is ok, and the sound quality is good. If you don't care about the smaller screen, MX2 can also pay attention to it. Meizu is recognized as a quality control and labor party, which is not comparable to ordinary mobile phones. It is a personalized boutique mobile phone. 1699 is a great value. The visual area and effect of a 4.4-inch screen are comparable to those of a 4.6-inch ordinary 720P screen, with excellent comprehensive performance and good user experience. That's all. So far, these are the only things worth starting with. They are not futures. You can buy it if you want. Personal suggestions for your reference, original answers, I wish you a satisfactory mobile phone.
