Starting from the second half of 2012, many flagship phones using Qualcomm APQ8064 platform, which advanced quad-core CPU Krait schema match the new Adreno 320 graphics processor provides strong support for these phones. On the CES2013, Qualcomm released a new set of Xiao long 600 platform, to take APQ8064 's place. As the first Xiao long 600 cell phone, Optimus g Pro high hopes were, of course, its actual performance, we will pass the evaluation to explore.
LG Optimus g Pro parameter

Seen from the parameters, LG Optimus g Pro is undoubtedly represents the highest level of today's cell phone, machine highlights that Gao Tongxiao Dragon 600 processor, of course, he code-named APQ8064T, seen from the model, or know it and our common APQ8064 is "twin" is Adreno GPU 320. Krait 200 upgrade CPU core from APQ8064 to Krait 300, high pass known as the highest 40% of performance. Of course this is a nominal value, the actual level, or to look at the actual experience. In addition, Optimus g Pro screen is also a major attraction, and Samsung Galaxy Note II the same size screen, but at resolutions up to 1920*1080 and using LG their True HD IPS+, display is definitely present on the top of the screen.
Design
Seen from the front, Optimus g Pro and Galaxy exactly the same Note II, there was a 5.5-inch big-screen, below has a solid Home key, next to the two touch-sensitive keys. Optimus g Pro, by design, more color, using the design of ultra thin border
Receiver and also similar to the flagship Optimus 2X LG has, next to the earpiece is a distance sensor, light sensor, and a front-facing camera
Galaxy Home keys Note II is very narrow, and on both sides of the touch keys and Samsung design instead, returns on the left, the menu on the right
Home also has a "hidden feature" is light, and the effect is gorgeous and colorful
Seen from the back, Optimus g design and Samsung Galaxy s Pro III is similar to Optimus Pro g back joined the blinking and Nexus 4 similar grid pattern, this is LG's flagship common design
The back Horn and Flash are provided on both sides of the camera
Top noise-reducing microphone, IR and 3.5mm interface
Is microUSB interface on the bottom and the main microphone
Is a shortcut button on the left side of the fuselage (customization), and volume key
Open key on the right side and an open Groove
After open the back cover, you can see a silver design, battery covers a large area, capacity up to 3140mAh, back cover for NFC coil
Support TF card extension, next to the micro-SIM card
Display
Optimus g Pro's big selling point is that a 5.5-inch full HD IPS screens, but Word of mouth is better LG original screen, here is this screen performance, color gorgeous
Ted Baker note 3 covers
Run full HD game images
But it is regrettable that, Optimus g Pro is not popular now all fit on the screen, and black box around the screen is wide, with the white fuselage, gives the feeling is not very good
Although it is 5.5 inches, but due to the high resolution 1080P, PPI has reached 400, well beyond the "retina" level, very high degree of precision
IPS screen's viewing angles are very good, but in the "diagonal of death" will still be on some partial color
This "left-blue, yellow right" identification of many dubbed LG's performance was an important feature of the phone screen.
The system UI
Due to LG UI and a lot of work into, make up, the evaluation of Optimus g Pro UI will be described in detail. LG's UI gives the feel and style of the Samsung TouchWiz interface is similar, but on some of the details of the deal will still be quite a lot of difference.
First, the system's Launcher, style and TouchWizh are identical, even the application icon is on the table right below the level of the menu, but compared to Samsung, LG is the secondary menu icon support for custom locations, and not just in the lower right corner
-System initiator is rich in special effects, support for custom and animated transitions are very beautiful, also supports system subject switch, but not as many as
Add the plug-in launcher plug-in features plug-in not many
Desktop icons at first glance does not seem to be too many features, in fact, LG also spent a lot of effort on an icon, some system comes with support for icon size, but also supports icon replacement, giving users plenty of customization options seemed very user-friendly
Because I hand this Optimus g Pro is Korea operators to customize, so in many parts of the system will see a lot of custom software, and many need to be after the root cannot be deleted
Some system software through the application manager uninstall
Secondary menu may seem relatively normal, and other mobile phone there is no significant difference between
More functions of the drop down bar, also has a strong three-star style, and can provide a shortcut to edit, in addition to brightness and QSlide apps feature
QSlide apps is some program shortcuts in the dropdown settings, but does not support adding custom applications, only comes with several systems and software to support this mode
More characteristic was QSlide programs can support multiple Windows apps (supporting up to two suspension Windows), and the window to where you want to move, and the size of the window can also be defined. Following are floating Windows calculator and browser demo
To unlock the interface, Optimus g Pro unlock interface is very diverse, you can set up multiple unlock animation effects, as shown in the figure, which is often in a number of third-party screen lock software to be able to see, but LG animation transition very natural. Lock screen clock also has a number of options, you can select the digital clock, analog clock, calendar, and weather, and a variety of lock screen content
Set interface more conventional, more just color scheme changes and, of course, add some features, the system is based on the Android 4.1.2
Long press the Home key to display multiple task switching and Task Manager, power on the system RAM available around 1G
Network Setup, support global roaming settings. Optimus g Pro in the NFC the coil on the back cover, NFC-enabled feature, which is now the flagship model one of the necessary functions
Many display settings changes, in addition to supporting similar to Samsung's "smart screen" (that is, detecting eye when looking at the screen, the screen kept open), you can touch lamps, Led Home key settings, Home button is backlit to support setting, but unfortunately, you cannot customize the backlight color
Gesture and one-hand operation, these two functions are there suspicion of Samsung
One hand support the dial pad and LG keyboard
On the fuselage side a QButton buttons, you can customize the keys function, shortcut to open any application
Other features
Optimus g Pro comes with powerful video processing, video, photo, audio splicing
Also supports editing of video, adjust sound and other functions, it is suitable for users who have special requirements for video
Through infrared at the top of the fuselage, Optimus g Pro can also be used for remote control such as TV, air conditioning, the next picture shows the remote control TV
Performance
Performance of the parts is undoubtedly the focus of this evaluation, as Xiao long 600-processor cell phones, our actual performance of the SoC are also full of expectation. APQ8064 mix 1080P screen a lot of games have suffered different degrees of Caton, Xiao long 600 will be significantly improved? Mycophenolate Mofetil 600 processor model APQ8064T, uses the Krait 300 core quad-core processor 1.7GHz, matching Adreno 320, the overall performance is now top of the SoC level we Xiao long 600 performance will also be more comprehensive testing.
Theoretical performance
Rabbit test (3.1.2), although it was "entertainment" nature of the software, it can still see some problems.
Initial test score is not very ideal, "only" around 20,000 points, and lots of APQ8064 mobile phone, even on the graphics test scores or lower
GLBenchmark 2.5, this is a old graphics test software, Optimus g Pro and APQ8064 phones there is no significant difference (most Egypt HD 29 frames of reference value of APQ8064 cell phone at about 30 frames), it seems that Xiao long 600 Adreno 320 APQ8064 there is not much improvement
Rabbit 3D test, this is a rabbit special test to measure split, has more accurate evaluation on mobile GPU performance, Optimus g Pro played well, achieved an average score of 22.6, Adreno 320+1080P devices, this is a pretty good achievement
The Web performance test
After the author of the test, even with "run dedicated" browser Chrome Beta and Baidu, in many cases scores less Optimus g Pro's browser, this is obviously the browser optimization problems, so the test used in the browser.
Sunspider, this is a very common Web Javascript performance test, single-threaded capability test CPU, Optimus g Pro has outstanding performance, total is 894.1ms (see Xperia Z:1296ms, lower value is better), this is the best I've tested the Qualcomm processor, can be comparable to the Exynos known for CPU performance 4412
Google V8 JavaScript Test,Optimus g Pro good play in this test, the score is 2174 (see Xperia Z:1788)
Vellamo, which is Qualcomm launched a test HTML performance of mobile phone software, Optimus g Pro in this test are still eye-catching performance, HTML5 is 2481 (see Xperia Z:2210)
Game testing
General running test is a little too theoretical, buy high-performance mobile phone many users will attempt to big game, so here will be also added to the game testing, with the FPS meter frame detection software to detect frames.
Need for speed 17
EA company classic racing game, picture quality in mobile games also at the highest levels, the load is also very high, Optimus Pro only 18 g frame (Xperia Z:21 reference frames), is not running smooth, even as some APQ8064+1080P's mobile phone
Real racing 3
EA recently launched high-quality racing, on the GPU is very high, Optimus g Pro only averaged 16 frames (see Xperia Z:20 frame) levels, runs extremely smooth
Wild biker 7 (1.0.5)
Emphasizing version 1.0.5, because the latest version to a new picture quality evaluation of the high-pass GPU, past high-pass GPU are in lower effects, and finally "turn over", Adreno 320 drag racing in this version of the wild 7, picture quality excellent. Optimus Pro g average about 20 frames in this game (Xperia Z:27 reference frames), very smooth
Wild blood
Wild blood is 2012 action game masterpiece, but optimized for Android devices is not very good, so far no pieces of equipment can run smoothly, Optimus g Pro is only an average of 22 frame (refer to the Xperia Z:24 frames)
Blade Slinger
This is a new action game, known as mobile gaming best picture from the screen really is mobile gaming leader. Optimus g Pro is finally ushered in a smooth running of the games, frames 30 frames (see the Xperia Z:30 frame)
Modern warfare 4
Because this game is not like a wild drag racing 7 updated version of it on the Adreno 320 support is still insufficient and the overall picture quality at a relatively low level, although the picture quality is not high, but Optimus g Pro is the card, only 22 average number of frames (see Xperia Z:32 frames)
Epic Citadel, which is a display of the game, since frames test, Optimus g Pro has also managed to save some face, frame number 55.9, it is the 1080P device inside the top level
Some users may question the accuracy of frame software. Indeed, the opened frame detection software can slow game performance, but only 20 frames in a test of the reach of cell phones, may actually run smooth do? We use a simple and direct method to verify the problem. In the tests, 17 average number of frames in the need for speed is about 18. Close frame detection software, mobile phone directly from the cooling to start the game, and used a timing device. From the diagram we can clearly see, even excluding the outside interference, fully functional cases, Optimus g Pro in actual 1 minutes 21 seconds of the game, it takes 1 minute 45 seconds to complete
Reduced frequency problems
On the block issue, there has been a lot in the previous generation APQ8064 phone, Nexus 4, Optimus g, Z5 has reduced frequency problems in products such as, which is in use for some time, even in daily use at room temperature will appear different CPU frequency drop, below we will block for testing.
First rabbit (3.2.1), continuing the LG "good tradition", at the entrance to rabbit's instant, automatically lock the CPU frequency to high frequency, if not open runs will remain locked in the high frequency. This author has explored before, this is a popular "run optimization" method, not a cheat. As shown in the figure, CPU share low, but quad full high frequency
And then begin the rabbit test, when it was 41% when the test, CPU block to 1.1GHz, this phenomenon is not difficult to explain why Qiang Ruxiao Dragon 600, runs just over 20,000
Then we had freezing test environment is the fridge, ran improve obviously, more than 25,000 points, reaching the highest level now
Then attach a new 3.2. running version 1 is still running freezing conditions, some lower scores compared to the old version, it may be the software algorithms and error problem
Then there is still the refrigerator test, test software is GLBenchmark 2.5.1, the project is Egypt HD. Test scores higher than room temperature, a 2fps increase, to 31fps
May will has users questioned, run points software as test cannot description problem, author also specifically using has actual application to confirmed this a problem, using BSPlayer 1.8 for soft solutions video of test, video format is 1080P 60fps ref=16 of MP4 video, a began play video of when, also is "full blood" run, average frame number reached 30 frame around, even can comparable Orion seat 4412
But by the time play a minute, annoying block phenomenon, directly down to the 1.1G, frame number has plummeted to about 20 frames
Use CPU SPY detect CPU frequency changes, but in the case of play a little video, CPU frequency is often reduced to 1.1GHz, or even 918MHz, Optimus g Pro frequency reduction is a serious problem
Additional testing
In LG Qualcomm SoC devices in the past, there will be a "lower resolution" settings. Described in the system is "aspect ratio correction" is in fact mandatory for specified applications reduce the resolution (down to 800*480), the intent is to avoid compatibility problems with the 16:9 screen, we can also turn on this setting to see whether the game was not smooth lifting frame
Real racing 3
By imposing lower resolution, frames improve a lot, already running the game, number 29 (1080P 16), of course, to run the game to the left and right sides of the frame with black edge, game quality decrease
Need for speed 17
After the lower resolution, frames 17 need for speed upgrade is very large, over 40 frames (1080P 18)

Video decoding
For a 1080P mobile phone, play full HD video is very good, that Optimus g Pro video decoding capabilities and how? Because Optimus g Pro uses a full HD screen, so test all of 1080P videos here, using BSPlay 1.8 for the player, the following is played
Clannad OP,MP4,1920x1080,H.264 High Profile L5.1
Video frame: 24 actual player number: 23.84 (hardware decoding)
Ted Baker note 3 cover
Battlefield Valkyries 3 OP, MKV,1920x1080,H.264 High Profile L4.0
Video frames: 30 actual playing frames: 29.51 (hardware decoding)
Microsoft WMVHD official video, WMV, 1440x1080,VC-1, MP@HL
Video frame: 23 actual playing frames: 23 (software decoding, since players can be hard solution)
Fate/Stay Night OP,FLV,1920x1080,H.264 High Profile L4.0
This video hard a little too large for the phone, test goal it is to look at the video of soft solutions Optimus g Pro will appear when frequency reduction, from the practical standpoint, even soft solutions video case, decoding Optimus g Pro is a single core, are often not up to even the most high frequency
As can be seen from the test, Optimus g Pro video hardware decode capability is still quite strong, 1080P MP4, MKV and WMV files can be hard solution, with a 5.5-inch full HD screen, video experience is very good.
In addition, sell buy Optimus Pro g 32G Rom, available capacity is about 23G, and support more than 4G individual files, external TF card support exFat
Photos
Optimus g Pro uses a 13 million-megapixel back-illuminated camera aperture is F2.4,LG phone photo quality is not good, the Optimus g Pro lasted for 13 million-pixel camera on the Optimus g, what are the actual performance? We look at the Optimus g Pro Photo performance.
Camera interface is clean, various options are not difficult to understand, but still and Samsung are similar in style, here are some settings for contrast, visible layout is largely similar to the options but LG appear more graphical (above, LG, and Samsung under)
Comparison of shortcuts (on the LG, Samsung under)
While taking pictures like the menu style and Samsung, but Optimus g Pro Photo has its own characteristics. In addition to supporting other than volume button the shutter, the biggest bright spot is that it supports "manual focus" feature, this functionality comes with the camera is rare, but for the average user, believe it is biased "fool" cell phone photos
From the picture quality, Pro and LG Optimus g like the previous style, sharpness is generally screen smudge marks are also very serious, so here are some picture (click to see original image)
Night camera white balance no, noisy and more (click to view original image)
Overall, the LG in the past 8 million pixels phone, Optimus g Pro are still elevated, but compared with competitor products at the same level, Optimus g Pro is also a big gap and hope LG photos optimization will do better in future.
Temperature
A lot of APQ8064 phones in temperature are very general, and heat is large, and the APQ8064T in the more high frequency, but Qualcomm claims has improved due to the processor core, so power consumption is relatively better, we pass the practical test to verify whether this is true.
After 20 minutes the game tests, Optimus Pro g fuselage maximum temperatures around 34 degrees (non-handheld, cell phone no load condition), the temperature is not too high, of course we would also like to note that it has serious problems down, and high temperatures are also expected
Battery life
Optimus g Pro uses a removable 3140mAh battery, supporting the 5.5-inch screen and a huge power high frequency quad-core processors. From the practical standpoint, thanks to the battery capacity is large enough, Optimus g Pro battery life performance. Large 3D game after a 20-minute and 30-minute WiFi Internet, residual 82% power. Optimus g Pro comes with power management or power consumption trend, according to this law, normal strength in time could be closer to 5 hours of continuous use
Additional GLBenchmark 2.5 battery life test (100% brightness, 60FPS high-strength test), as can be seen from the chart, the more serious CPU frequency reduction, in terms of battery life is better than down, with Optimus g Pro, large capacity battery, so in this test of endurance ability
Signal
Since this is the Korean version of the F240L, so unfortunately does not support mobile EDGE, using a mobile card users if you are using the phone with Internet speeds will be even worse. While China Unicom users can use 3G network. Signal strength, Optimus g Pro performance satisfactory, the signal strength at the same location better than Galaxy Note II 5~6dBm,2~3asu
Summary
Optimus g Pro is a phone that was both surprised and disappointed by people, in shape, UI design and configuration are LG's sincerity. Work relative to the Optimus 4X era of HD products have quite a bit of progress, Director of UI design, while Samsung's shadow, but in a lot of detail has its own characteristics. On the hardware configuration, first mycophenolate mofetil 600 processor does seem gimmicky, 5.5 inch 1080P screen is amazing. But from actual using Shang view, Optimus g Pro is is sorry himself of configuration and worth, most serious of problem is CPU of drop frequency, even is in at room temperature Xia soft solutions video will appeared exaggerated of drop frequency phenomenon, this is somewhat justified, in actual test in the, in some large game in the performance also is poor, this and itself of CPU drop frequency and GPU effectiveness are about. Sorry is that Optimus g Pro in cryogenic environment is required to play the Xiao long 600 performance. Pictures, Optimus g Pro extended LG style standard is far from satisfactory. As the first 1080P cell phone LG, Optimus g Pro is to "Galaxy Note II-killer" appeared, but from a practical view, except for the screen and UI features, Optimus g Pro basic overall disadvantage relative Galaxy Note II. From LG's own product progress, Optimus g Pro is also a rare good faith work, hope it via a future firmware upgrade, can gradually improve block and camera algorithms play out Xiao long the real power of 600 and 13 million cameras.
