Nexus 4 brothers Optimus G hands-on experience | love computer games - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Nexus 4 is the famous fourth generation son of Google. It is welcomed by many users because of its excellent cost performance and son's pedigree. And in Nexus 4 Under the light of the Nexus 4, we seem to have ignored its "predecessor" - LG Optimus G. This phone has many similar design elements with the Nexus 4, and is more powerful in configuration.

I believe everyone is familiar with the configuration of Nexus 4. Let's take a look Optimus G configuration ：

Model: LG F180L (Korean version)

CPU: Qualcomm Snapdragon S4 Pro APQ8064 Quad Core 1.5GHz

Operating system: Android 4.1.2

Screen: 4.7 inch 1280 * 768 resolution True HD IPS screen

SIM card type: microSIM

Storage space: 32GB (expansion not supported)

RAM：2GB

Connection: Bluetooth ®, Wi Fi ® IEEE 802.11 a/b/g/n, Micro USB, 3.5mm audio interface

Camera: 13 million pixel backlit F/2.4 aperture, 1 million front.

Battery: 2100mAh, non removable

Others: NFC

Phone size: 131.9x68.9x8.45mm

Mobile phone weight: 145g

In terms of configuration, Optimus G is more powerful than Nexus 4 in terms of configuration. Its 13 megapixel camera and 32G storage space are its advantages. The most gratifying thing is that from the perspective of the reformer market, the market price of Optimus G is about 100 yuan lower than that of Nexus 4, and the cost performance advantage is very obvious.

For the twin brothers Optimus G and Nexus 4, their differences in shape and configuration are very small. This article focuses on the differences between Optimus G and Nexus 4.

appearance

From the front, Optimus G has a typical LG style. Due to the use of the full fit screen and the fact that the touch key is not lit, it is almost invisible, so the front looks black except for the logo and the camera, which is also a popular "high-end black". Of course, compared with Nexus 4, it is more low-key when it does not even have a logo ▼

Optimus G earpiece ▼

Compared with Nexus 4, Optimus G has three touch keys on the front, and these three keys have their own white backlight. Compared with virtual keys, ordinary users are more likely to accept touch keys ▼

The signal light of Optimus G is relatively "stingy". There is a small led signal light on the left side of the front camera, which is opposite to the big signal light and Optimus G Pro The signal lights of the Home key should be low key ▼

The Optimus G is square, while the Nexus 4 is round. There is a piece of glass on the back of both, so users should pay special attention to prevent falling when using it. The positions of their cameras and speakers are the same ▼

Difference of back pattern ▼

Optimus G uses 13 million cameras, so the position of the lens will protrude ▼

The Nexus 4 on the side is made of anti slip material, while the Optimus G is made of piano paint ▼

The left side of the fuselage is also the same height, which is the volume key and SIM card slot ▼

The top is a noise reduction microphone and a 3.5mm interface. Of course, Optimus G is a Korean version, and it is ▼ with an antenna

At the bottom are the microUSB interface and the main microphone, as well as the two landmark screws. Many users think this is a failure in the design of the Nexus 4 ▼

UI

Since Optimus G uses LG's official system, and Nexus 4 uses Google's native Android system, there is a big difference between the two in terms of system and UI. Of course, we have introduced LG's system in the evaluation of Optimus G Pro, and Google's native Android is also a system that everyone is familiar with. Here is a brief introduction of Optimus G's UI.

Compared with Optimus G Pro, the location of Optimus G's starter is more tight. The layout of Optimus G's starter is 4 * 4, while that of Optimus G Pro is 5 * 5, and the search column of Optimus G cannot be deleted ▼

In the system menu, drop-down bar, etc Optimus G Pro Basically the same. It is worth noting that Optimus G does not have the function ▼ of QSlide apps

Launcher and lock screen can add many special effects, which is also LG's UI feature ▼

Optimus G has a unique feature that it comes with a "four core control" option, in which the Eco mode can be turned on. After turning on this mode, two CPU cores can be turned off. We all know that the power consumption and heat generation of APQ8064 are relatively objective. This setting can effectively control the CPU power consumption. Of course, what needs to be sacrificed is the CPU performance ▼

The built-in 25G free space is a big advantage of Optimus G. ▼

performance

Like Nexus 4, Optimus G also uses APQ8064 1.5G plus 2G Ram. The difference is that Optimus G uses LG's own system. How about LG's optimization level of APQ8064? Let's take a look at the performance measurement

Theoretical test

Antu rabbit evaluation

Optimus G got a very "standard" APQ8064 score, which exceeded 20000 ▼

Optimus G performs well in this GPU test ▼

GLBenchmark 2.7

In the GPU performance test of version 2.7, the performance of Optimus G is not much different from that of other APQ8064 devices (Offcsreen frames: 14fps), but in version 2.5, Offscreen is only 21fps (normally around 30fps), and the performance is relatively poor. The reason for this is mentioned below ▼

BaseMark X

For the new GPU test software built on the Unity 4.0 engine, the frame number of Optimus G in the On Screen mode is not much different from that of Nexus 4 at the same level, but there is a big gap in the Off Screen test ▼

practical application

Optimus G does not show any surprise in this single thread test, and it is also similar to other mobile phones that use APQ8064 ▼

Video soft solution

Video software decoding is also an important test item to measure the general performance of CPU. This test item tests the multithreading performance of CPU, which is different from the video hard solution. It is a method to test the CPU's computing ability. What is tested here is a 1080P 60fps ref=16 MP4 video. The number of frames of Optimus G is 23, which belongs to the normal range ▼

game

The following tests two mainstream large-scale games, Dungeon Hunter 4 The average number of frames of is 30 (general scenes, highest special effects) ▼

In some complex scenes, there are only 24 frames on average, and the picture appears stuck ▼

The average frame number of real car 3 is 29, and the frame number performance is also average ▼

Modern war 4, average frames 28, poor performance ▼

Frequency reduction problem

From the above test, we can see that the GPU involved in the test process is prone to exceptions. What is the reason for this? We can see the frequency control policies of CPU and GPU ▼ by viewing System/etc/thermald.conf

It can be seen from the figure above that when the temperature reaches 42 degrees, the CPU frequency drops to 1188MHz, the GPU drops to 320MHz, and the GPU drops to 200MHz when the temperature reaches 44 degrees. This explains why the scores of so many previous tests are not ideal.

In addition, we check the CPU frequency through the system information Pro. In modern war 4, although the CPU frequency remains the highest frequency, actually only dual core operation is enabled, which will also affect the performance of the game to some extent ▼

Even when the dual core is turned on, the temperature of Optimus G is very high, and the maximum temperature of the screen surface has reached 45 ℃ ▼

When the temperature of the mobile phone is too high, the frequency of the soft solution video will be reduced, as shown in the figure below. Although the four cores of the CPU are all turned on, the CPU is reduced to 1.1G ▼

photograph

The photographing of the Nexus 4 has always been a weak part, while the camera of Optimus G is 13 million pixels, which is better than the Nexus 4 in terms of parameters. The following is a comparison of the actual shooting effect

From this photo, the Nexus 4 has a serious color deviation problem, and the picture is smeared seriously, and the sharpness is not as good as Optimus G.

In this picture, the performance of the two is similar, but it can be seen that the noise of Nexus 4 is more serious than that of Optimus G.

Finally, I would like to mention a more "against the sky" way of playing. Due to the high consistency of hardware, some developers even swiped the BootLoader of the Nexus 4 into Optimus G. This means that Optimus G can enjoy the powerful resources of the Nexus 4. Of course, directly swiping the ROM of the Nexus 4 will cause some small problems, such as the abnormal operation of its 32G and 13 million cameras. For Optimus G itself, many native style ROMs such as AOKP and CM10.1 have appeared, which has greatly improved its playability ▼

summary

Optimus G, as the "original" of the Nexus 4, has remarkable performance in all aspects. Compared with the Nexus 4, it has great advantages in photographing, and LG's performance in UI is also satisfactory. Optimus G performs generally in games, which is mainly caused by GPU frequency reduction. Of course, we can use some unconventional methods to solve this problem, but due to the high heat generated by the mobile phone itself, even if there are these methods, they are all solutions that address the symptoms rather than the root causes. The key problem is that the heat control and heat dissipation design are not good enough. In terms of daily use, LG's UI feels good and smooth enough. Compared with the market price of 2300 yuan, Optimus G is still a phone worth buying.
