Qianyuan dark horse - music as 2 X528 mobile customized version of the box comment

Due to the growing disillusionment of the Red Rice NOTE by adults, the task of buying a suitable machine has fallen to me. Price limit 1k or so, during the considered millet 4 / red rice series, although the MIUI is good just a lot of advertising is less and less cost-effective direct PASS; charm blue series of quality control word of mouth is also more and more complaints continue PASS; Huawei once signal The quality of the call is not as good as it used to be, and colleagues around me bought me to change the machine for several times to keep me away from it; Nubian mini feels good, but it's a pity that the high-priced shell is pseudo-glass. The system's criticism is also very worrying. Continue to PASS. ; The new out of 360 is very good but unfortunately the shadow of the 360 ​​family barrel too heavy to choose, and then stared at the other recommended by the music as 2, only to find the machine configuration with good value on the consideration.

Last store card, the final purchase is to buy a mobile customized version of the X528 at the local wholesaler price of 990 yuan.

Buy a custom machine just for the Qualcomm 652 chip, it is not optimistic about MediaTek X20.

On the box:

The package contains a host, a charging head, a type-c data cable, a type-c headset interface, comes with a clear water jacket.

ID no border is very coordinated under the black wallpaper background, the three virtual keys on the chin do not touch does not show, do not show when always feel empty is not used to

The edge of the metal matte polished texture, the light is even higher at the end of the atmosphere. Say it is gold, looks closer to rose gold, this color men use not quite right, lady is very good. Friends of the value of the sun alone said that the cut-off I did not feel that this Taiwan will be cut.

Three-section front design

The back of the aircraft is thinner than the iphone6, and more coordinated; the camera is slightly raised, the mirror fingerprint recognition touch is very good, support the screen to unlock the bright screen, the success rate of hand water recognition is much higher than the iphone6.

The physical buttons are centered on the upper right side, and the volume keys are separated from the opening key by a groove.

The SIM card slot is at the top of the left side of the fuselage, and the volume keys on the right side are symmetrical. The light sense on the top of the camera is symmetrical with the front camera to the center of the receiver.

The bottom of the fuselage is also symmetrical, it seems that this designer is very like OCD.

----------------------------- Appearance Partially Ended ------------------ -----------------

Buying new machines can't help running away

The ranking is not high, which is 10,000 lower than the music score of X20 version. It can be seen that MediaTek's X20 is very good at running. However, to buy this is to take a look at the balance of Qualcomm 652, running points low does not matter.

The device information is as follows:

Fast charge test: 20:45, 22% power


22:21, electricity 100%, spent 1 and a half hours, 0-100% is expected to take 2 hours, scores also live

Mild use of two days no problem, put one night on the power consumption of 1%, but the APP installed not much to 10, pre-installed software can delete deleted, in addition to music as their own app is the other Delete it properly.

One interesting setting is the unlock pattern. Pressing the power button to light the screen requires a move to move the screen up. If the position is centered, the position of the unlock pattern follows the middle.

Left side up, left side

Right side up, right side

It is very considerate for one-handed operators to consider, praise.

The contents of other aspects of the operation, other sun bills have been mentioned not repeat.

----------------------------- Photography ------------------- -------------------

Hand on a iphone6, used to do photo comparison is a bit bullying music, but the feeling is still enough after the comparison, iphone6's rear camera is said to be IMX220's upgrade section of 8 million pixels, music as the rear camera 2 is 16 million Pixel OV1688.

The following comparison chart on iphone6 ​​and LeEco2:

Iphone1

Le 1

Iphone2

Le 2

Iphone4

Le 3

Iphone4

Iphone7

Le 6

Iphone8

LeTV's imaging is warm, the shooting viewing angle is large, iphone6 ​​is cold, the viewing angle is too small, music as the noise is more than the iphone, the darkness of the night scene is dark, and there is some incompatibility with the propaganda on the night view.

Iphone6

Le 5

Music as the end of the photosensitive element larger than the iphone, aperture is larger, so the macro shot iphone depth of view a lot, but the blur should be more than iphone to please some. The recent shooting distance from LeTV is about 2cm farther than the iphone.

Overall, the effect of the camera is very worthwhile for this price point, but the advantage of high-pixel is not reflected, too much on the iphone tuning, I hope the firmware can be optimized later.

Finally, here is a summary:

Advantages: 1, good-looking, all-metal feel good, lightweight;

2, the hardware configuration meets this price, and it can even be said to be excellent value for money;

3, touch screen touch good, rapid response without stickiness;

4. There is no advertisement in the home video play APP, and the speeds of the three major operators are all levers.

5, camera focus quickly, do not run coke, imaging level is good;

Disadvantages: 1, fast charge for the 4000mha battery, the speed is not fast;

2, the so-called ID without borders, against non-black wallpaper, it does not look good, always can not always use black

However, it's better to get the frame out;

3, the camera's tuning still needs to be strengthened, it is best to increase the adjustment aperture options, otherwise the total sharpness under large aperture

It is worse;

4, comes with the software store quite rubbish, no speed under the mobile broadband, there is a pile of useless push

Recommended, it is recommended that you install one other use;

5, LeTV LIVE button position can not be adjusted, the function is very good, slightly inadequate.

To sum up, the value is a word, and the valued friend who wants to get started is slightly early.

Linear Power Supply

A Linear Power Supply is an electronic device designed to provide a precise and stable DC voltage output from an AC input. It utilizes a linear regulator to maintain a constant output voltage despite variations in input voltage or load current.
Working Principle
Transformer Stage: The AC input voltage is first stepped down by a transformer to a lower AC voltage level.
Rectification: The transformed AC voltage is then converted into pulsating DC voltage through a rectifier circuit, typically using diodes.
Filtering: A filter circuit, often consisting of capacitors, removes ripple from the pulsating DC voltage to produce a smoother DC output.
Regulation: A linear regulator adjusts the output voltage to maintain a precise and stable level, despite changes in input voltage or load conditions. This is achieved by dissipating excess power in the form of heat.
Key Features:Stable Output、Low Noise、Excellent Regulation、Simple Circuitry
