Within 3 thousand, the most suitable mobile phones for freshmen are all here.

In high school, besides "it will be easy when you go to college", our parents often say "I'll buy you a new mobile phone when you graduate".

However, the biggest problem for prospective college students to buy mobile phones is that they don't know which one to choose and how much budget to report to their parents for approval.

Now all brands have laid out full-price mobile phones, and the advertising methods are becoming more and more complicated. Which parameters really need reference, and which configurations really affect the use of mobile phones? Every manufacturer is telling you different answers.

This time, taking "cost performance" as the only measure, ten mobile phones with a price of less than 3,000 yuan were selected from the airport and recommended to college students who are about to become college students or have plans to change their mobile phones.

At present, realme and Redmi can be said to be two giants, which can put aside the brand premium and provide super high cost performance.

One of the costs of high cost performance is that the mobile phone's appearance recognition is very low, or it can't get excellent design.

The real mobile phone is a rectangular black lens module, and some huge LOGO are added in different positions on the back cover.

Redmi's Redmi K40 series lens module adopts "gas stove" design, which is not beautiful, but at least it has its own characteristics. Red rice Note 10 Pro adopts "can" design, inherits the design of Xiaomi 10 Ultra, and opens up the recognition with other mobile phones.

The recommended iQOO, Black Shark, Xiaomi, Yijia and other mobile phones also have their own design languages. One plus 9R looks similar to flagship machine one plus 9, and its appearance is more expensive.

However, these are all things that can be solved by a mobile phone case. The glass you stare at every day may be longer than your sleep time. Maybe you should pay more attention.

Whether watching videos or playing games, the quality of the screen can determine whether your entertainment experience is good or not. When we face a screen, the most obvious perception is its clarity and color performance.

Whether the mobile phone screen is clear or not, the most critical parameter is ppi. The screen resolution and screen size * * * all determine the ppi size of a screen. The calculation of ppi is also very simple, and the formula is:

At the Apple conference in the fall of 20 10, Jobs gave the definition of mobile phone screen. At a distance of 0/2 inch (305 mm) from the human eye/kloc, when the ppi of the mobile phone screen reaches more than 300, the human eye cannot distinguish the pixels, which is the "retina screen".

The IPhone 4 became the first IPhone equipped with a retina screen with 326 ppi pixels per inch.

Today, thousand yuan mobile phones are also equipped with 1080p or higher resolution screens. Realme Q3, the lowest price among the ten mobile phones we recommend, costs 1 199 yuan in official website, and the screen can reach 405 ppi per inch.

Another hardware that was decentralized to the thousand yuan mobile phone is the organic light-emitting diode screen.

In the LCD screen widely used in the past, sub-pixels need the whole backplane to illuminate and display colors. This structure has many layers, and the sub-pixels showing black will also be illuminated by the light of the backplane, and what the human eye sees is actually deep gray.

The sub-pixel structure of OLED is very simple, and each pixel can be turned on and off independently. This kind of screen is not only much thinner, but also turns off the lights when it is dark. This kind of black is "true black".

Because of their different working principles, the contrast of OLED screen is much higher than that of LCD. In addition, compared with LCD screen, OLED screen has the advantages of power saving and more bending.

Of course, there are different levels of OLED screens. The subpixel arrangement of OLED screens used in low-cost mobile phones will adopt the legendary "Zhou Dongyu arrangement", so the actual ppi of such screens will be discounted by 2 to 3 times compared with the original calculated value. However, Redmi K40 and Black Shark 4 use Samsung's latest E4 screen, and the display effect is better than other mobile phones with the same price.

It is worth mentioning that Xiaomi 10S and One Plus 9R have all been tinted.

In the field of cost-effective machines, Xiaomi 10S and One Plus 9R are absolutely crushed by separate screen adjustment. Holding such a mobile phone on the bed in the dormitory, whether you are brushing videos or playing games in bilibili, your eyes can appreciate the accurate color rendering of every frame on the screen.

Just as a university without roommates is not a university, a mobile phone without game mode is not worthy of being called a mobile phone (except iPhone).

The ten mobile phones recommended this time all have game modes, but the real game experience still depends on the mobile phones specially designed for games: Redmi K40 Game Enhanced Edition and Black Shark 4.

The biggest difference between these two phones and regular phones is that they are both equipped with pop-up shoulder keys, and the extra two physical keys can double your operating experience.

However, whether you can play the game well depends on the chip.

In fact, Tianji 1200 and Snapdragon 870 are both flagship chips, and the ten selected mobile phones are worthy of "cost performance" largely because they are equipped with these two chips.

In addition, a mobile phone with high refresh rate and high sampling rate can give you a smoother experience whether you are brushing videos or playing games.

The two game phones recommended this time are also the two with the highest display frame rate and touch sampling rate. Black Shark 4 has reached the refresh rate of 144 Hz and the touch sampling rate of 720 Hz. You can't eat chicken with such a screen. It shouldn't be your mobile phone, it's your own problem.

In addition, the game phone also has a cooling module specially designed for games, and a microphone layout specially designed for voice. If there is a high demand for games on mobile phones, these two game phones that are not very strange in appearance are worth considering.

For students who like to take photos, if there are requirements for the quality of photos, it is suggested to choose from the mobile phones with a price of 2000 yuan+,among which iQOO Neo5, Xiaomi 10S and One Plus 9R have better camera performance.

Their main cameras are equipped with optical anti-shake function, which is no less than changing a more expensive photosensitive element, which can greatly improve the quality of taking pictures.

Even if you always sit in the last row of the classroom and only use your mobile phone to take the PPT of "This page is to be tested", these three mobile phones can ensure that you can take clearer photos. The stacking madman Xiaomi even used 10/100 million pixel photosensitive elements. Theoretically, Xiaomi 10S can take the clearest photos.

If you want to shoot vlog, Xiaomi 10S who can shoot 8K video is the first one. This is the highest video quality that these mobile phones can shoot, which can provide more room for adjustment in the later period.

In fact, at the price below 3,000 yuan, the main budget of the mobile phone camera is spent on the main camera, and other lenses either have poor performance or are directly used to make up the number.

For the main camera of a mobile phone, by identifying the model of the photosensitive element, you can know the pixel of this lens and the size of the photosensitive element, which is convenient for you to make a choice when buying.

In addition to photosensitive elements, lenses, algorithms and adjustments, and chips, these are all important parts that directly determine the final imaging quality.

Therefore, at present, many mobile phone manufacturers only talk about pixel behavior when promoting photos, which can be understood as hooliganism.

HMX used in Xiaomi 10S is the most powerful photosensitive element, and Sony's IMX598 and IMX682 are not bad. IMX586 has been adjusted for many years under the banner of Yijia, and its performance is not bad.

Even though some parameters of the two photosensitive elements used in models below 2000 yuan+look higher, the actual photos and videos are much worse in resolution and color reproduction.

In the dormitory, we all have an idea before going to bed, "charge the battery for a while and then take the mobile phone to bed."

Many college students will put a charging treasure for bed charging, but the charging power of the ten recommended mobile phones has reached more than 30W, and the charging speed is not bad. Charging treasure on the bed may gradually become a thing of the past.

Xiaomi 10S provides 30W wireless charging, and students who like to put it aside for a while can choose. Redmi K40 Game Enhanced Edition supports 67W wired charging, and the attached L-shaped charging cable is convenient for charging while continuing to open a group in the canyon.

Black Shark supports 120W wired charging, which can be fully charged in 17 minutes, eliminating the power anxiety when playing games.

However, due to various self-developed fast charging protocols, the fast charging speed claimed by many mobile phones can only be achieved with special wires and chargers.

At present, the common fast charging protocols on the market are PD, QC and PE. The unique fast charging protocols developed by ourselves include Huawei's FCP/SCP, vivo's and iQOO's flash charging, Xiaomi's and Redmi's MIFC's encrypted flash charging, and OPPO's VOOC flash charging is compatible with one plus WARP and my own DART flash charging.

In order to ensure that your mobile phone charges at full speed, remember to use the original wire and charging head.

After charging, the battery capacity determines how long your mobile phone can last. The recommended mobile phone capacity is 4400mAh-5065mAh. The bigger the battery, the more comfortable you will be sitting in the library fishing and playing games.

However, the large battery directly leads to the uncontrollable weight of the mobile phone. In order to make you play games more leisurely, the recommended two mobile phones, Redmi and Black Shark, both weigh more than 200g, which is quite a challenge for trouser pockets in summer.

After everyone in the dormitory turns off the lights and goes to bed, whoever can turn on the air conditioner in the bed to adjust the temperature will be the father of the whole dormitory tonight.

In addition to grabbing the air conditioner remote control, you can also buy a mobile phone with an infrared sensor. Among the ten mobile phones recommended this time, Redmi's and Xiaomi's mobile phones are equipped with infrared, so they won't get tired of hearing "Dear Dad" in the dormitory.

In addition, NFC function is almost standard on mobile phones. You can use it to simulate the access card of the dormitory, and you don't have to worry about not being able to enter the dormitory when you go downstairs to deliver food. You can also use it to pay by bus when you go out. Touching the gate is much more elegant than scanning the code to get on the bus.

There is also an "extremely advanced" 3.5mm headphone jack, which is a must for music lovers. With it, you can also reduce the consumption of Bluetooth headsets.

We sorted out the three functions of these ten mobile phones, and we bought the right watch.

It can be seen that the directions of these ten mobile phones are different, so how to choose?

If your budget is less than two thousand, then the following three mobile phones are all similar.

Realme Q3 is suitable for students with limited budget. The chips and battery life of lower-priced mobile phones may not meet the demand in the next two or three years. This mobile phone has the highest cost performance.

Realme Q3 Pro and Redmi Note 10 Pro take the light and thin route, and the other takes the stack route. The price is similar, and you can choose according to your needs. The latter is very suitable as a backup machine at home. After all, you can turn on the air-conditioning TV or something.

If the budget can reach 2000 yuan, you can choose between realme GT Neo Flash Edition and Redmi K40. It is still a thin route and a piled route.

If you are a mobile game party, these two mobile phones for games are highly recommended. Unfortunately, both of them are profile fingerprint recognition.

If you have a good budget and need more photos and videos, then the following three mobile phones will definitely meet your needs.
