谷歌的Nexus4智能手机测评
Editor's Note (April 20, 2013): The following review has not yet been edited for grammatical errors. A final draft of the review will be released soon.
For the original German review, see here.
Google is establishing itself as a hardware supplier owing to the growing success of its sold smartphones and tablets. Although Google has never contracted its subsidiaries with the build of the devices, it is common belief that Google is the manufacturer. However, the Nexus 4 is an LG Electronics product. To the dismay of many customers, the first Nexus 4 devices were sold out within no time in Google's Play Store. The second wave that was available from December 6th was again out of stock just before Christmas. Seen objectively, this is no surprise. The combination of price and state-of-the-art hardware is not the only selling point. Its innards are comprised of a quad-core Krait with 1500 MHz and 2 GB of working memory alongside the Adreno 320 GPU. The buyer can select between a storage capacity of 8 or 16 GB. There are no color options; it is only available in black. Google's new super weapon was a hot topic and was eagerly awaited even before it was launched. Read in our review whether it can meet the high expectations and how we rate it compared with the devices from the competition.
编者按（4月20日，2013年）：以下尚未被编辑语法错误。不久将公布最终草案审查。
对于的德国原装审查，在这里看到。
谷歌确立了自己作为一家硬件供应商由于其售出的智能手机和平板电脑的日益成功。尽管谷歌已经没有承包，其附属公司构建的设备，它是共同的信念，谷歌是制造商。然而，Nexus4的是LG电子的产品。众多客户的不舍，第一次的Nexus4设备没有在谷歌的Play商店的时间内被抢购一空。第二次浪潮是从12月6日就在圣诞节前再次脱销。客观地看到，这是毫不奇怪。价格和国家的最先进的硬件组合不是唯一的卖点。它的内部结构是由四核的Krait1500 MHz和2 GB的工作记忆了Adreno320 GPU一起。买方可以选择8位或16 GB的存储容量。有没有颜色可供选择，它只是提供黑色。谷歌的新的超级武器是一个热门话题，并热切期待，甚至在它推出。阅读我们的审查，是否能满足很高的期望，我们将如何从竞争中脱颖而出的设备相比。
Case
The design of Google's Nexus 4 has not undergone any significant changes compared with the Samsung Galaxy Nexus. It is still a plain black block at first glance. However, it becomes apparent that various materials have been used and that it is in no way an ill-considered design when looking closer at the device. Just like the iPhone 4 range, the non-removable back cover is glass. Consequently, almost the device's entire surface is glass. Only the rim is made of two polycarbonate components. The lower, bigger part is matte black and encloses both hardware buttons and naturally the ports. The upper part features a dark silver color and serves as the display bezel. The display's left and right outer edge exhibits a slight downward curve. Samsung's Galaxy S3 features a similar curve but in the exact opposite direction. The display bezel does not protrude and consequently does not provide the screen with additional protection against scratches.
Probably everyone knows this problem: You just polished the touchscreen and five minutes later you would again like to reach for the microfiber cloth. Cleaning the Nexus 4 is worth twice the effort because the back is just as susceptible for fingerprints as the front.
The casing's different materials make a very high-quality and very rigid impression. The smartphone can be twisted marginally with moderate force but is largely pressure resistant. Our test model exhibited one particularity. A clattering noise was heard from the inside when we shook it. The noise is produced by the camera's image stabilizer and is absolutely normal.
The casing is still only available in black and its size has only been modified insignificantly. With a length of 133.9 mm, it is marginally shorter than the Galaxy Nexus (135.5 mm). However, it is thicker, wider and heavier. The Nexus 4 has a width of 68.7 mm (difference: + 1.9 mm), a thickness of 9.1 mm (difference: + 0.2 mm) and weighs 4 grams more than its precursor. Thus, the Nexus range follows the current smartphone trend of increasing size. The manufacturer LG manages to install a 0.05 inch larger screen due to the slightly larger dimensions.
谷歌的Nexus 4的设计，未发生任何重大变化相比，三星Galaxy Nexus的。它仍然是一个普通的黑块乍看之下。然而，很明显的，已经使用了各种材料，它是没有办法在设计时考虑不周，仔细一看在设备。就像iPhone 4的范围内，不可拆卸的后盖是玻璃。因此，几乎设备的整个表面是玻璃。只有轮辋的两个聚碳酸酯组件。较低，更大的一部分是磨砂黑和封闭的硬件按钮和自然的端口。上部设有一个暗银色作为显示屏挡板。显示器的左侧和右侧外缘呈现略有下降曲线。三星的Galaxy S3设有一个类似的曲线，但在完全相反的方向。显示屏挡板并不突出，因此不提供额外的保护，防止刮花屏幕。
几乎所有人都知道这个问题：你刚刚擦亮了触摸屏和五分钟后，你会再次达到超细纤维布。清洁的Nexus 4是值得努力的两倍，因为背面是前面的指纹一样敏感。
外壳的不同的材料做一个质量非常高的，很死板的印象。智能手机可以轻微扭曲力适中，但主要是耐压。我们的测试模型展出的特殊性。时时听到噪音时从里面我们握手。噪声是由相机的图像稳定器，是绝对正常的。
仍然只提供黑色外壳，其大小只修改不显着。随着长度为133.9毫米，这是稍微小于Galaxy Nexus的（135.5毫米）。但是，它是更广泛和更厚，更重。在Nexus 4具有的宽度为68.7毫米（差：+ 1.9毫米），厚度为9.1毫米（差：0.2毫米）重量4克超过它的前体。因此，Nexus的范围如下规模日益扩大，目前智能手机的趋势。厂商LG管理安装0.05英寸的大屏幕，由于稍大尺寸。
Connectivity
The Nexus 4 closely follows the interface positioning of Samsung's Galaxy S3 contender. The very similar array cannot be denied, regardless of whether it is the 3.5 mm headset jack, volume rocker or power button. Like in the Samsung Galaxy Nexus, the successor features a micro-USB port which enables transmitting an HDMI or a VGA signal. Nothing stands in the way of multimedia entertainment on a big screen with the right cable. More information about that can be found here. Besides its use as a multimedia interface, the micro-USB port has two other important functions. It can be used as a removable drive when linked to a computer or for recharging the battery via the modular charger. Like in all iPhones, the 2100 mAh battery is not removable and can only be exchanged by a technician. As mentioned in our review of the Nexus 10, Google doesn't want to confuse the user and thus omits a micro-SD for memory expansion. Since this is also true for the Nexus 4, the potential buyer should carefully consider how much capacity is needed before ordering.
Our test device features a flash memory of 16 GB (net: 12.92 GB useable). There is also a model with 8 GB of memory capacity available.
Nexus4紧跟三星的Galaxy S3竞争者的接口定位。非常相似的阵列不能否认，不管它是否是3.5毫米的耳机插孔，音量键或电源按钮。像三星Galaxy Nexus的继任设有一个微型USB端口，使传输HDMI或VGA信号。没有什么突出的多媒体娱乐的方式在大屏幕上用正确的电缆。更多相关信息可以在这里找到。除了其作为多媒体接口的使用，微型USB端口有两个其它重要的功能。它可以被用来作为可移动的驱动器连接到计算机时，或通过模块化充电器对电池充电的。在所有的iPhone一样，2100毫安时的电池是不可拆卸的，只能由技术人员交换。我们的评论中提到的Nexus10，谷歌不希望来迷惑用户，从而省略了的micro-SD扩展内存。由于这也是真正的Nexus4，潜在的买家应仔细考虑订购前需要多大容量。
我们的测试设备具有16 GB（扣除：12.92 GB可用）闪存。还有一个8 GB的可用存储容量模型。
Software
There's no need to worry about updates. It is not an insignificant advantage when both hardware and software come from the same developer. The so far excellent update situation of the Nexus 4 will first deteriorate in a few years. Google's latest flagship is powered by the Android operating system Jelly Bean 4.2.1. Superfluous bloatware will not annoy the user and he can take delight in a very powerful and slim operating system. Shortly after the release of version 4.2, there was an update to the current version because of various bugs. The latest 4.2 version includes a few new features. One of these is dubbed "Photo Sphere" and enables taking 360° panorama shoots. This feature is very intuitive and using it works right away with a remarkable result. The navigation bar has always been an integral part of Android and is indispensable for the system. To increase utility even more, a subtle and at first nondescript facelift was performed. Now it is possible to exhibit further widgets in the right upper area when the message bar is opened. "Daydream" can be used when the device is connected to the charger or in a docking station. This feature is easiest explained with the word "screensaver". The current time, a slide show or other contents glide over the dimmed screen when the corresponding setting is selected beforehand.
软件
有没有必要担心更新。这不是一个无关紧要的硬件和软件两方面的优势时，来自同一开发商。到目前为止优良的更新情况的Nexus4将首先在几年恶化。是由谷歌的最新旗舰Android操作系统果冻豆4.2.1。多余的英国媒体报道不会骚扰用户，他可以把快乐建立在一个非常强大和苗条的操作系统。 4.2版本发布后不久，有一个更新到当前版本，因为各种错误。最新的4.2版本包括了一些新的特点。其中之一是被称为“摄影圈”，使360°全景拍摄。这个功能非常直观，使用它的工作原理，具有显着的结果。导航栏一直是Android和系统是不可缺少的一个组成部分。为了提高效用，甚至更多，一个微妙的，并在第一不伦不类换装。现在它有可能表现出进一步的消息栏打开时，在右上区域的部件。 “白日梦”时，该设备可用于连接到充电器或对接站。此功能是最简单的解释，“屏幕保护”。当前的时间，幻灯片或其他内容滑过暗淡的屏幕上时，预先选择相应的设置。
The Nexus 4 features a vast array of communication modules. The high-end device even sports an LTE chip although neither LG nor Google specifies it. Consequently, this chip is disabled and cannot be used (in Germany). An HSPA+ 42 module is installed in order to nevertheless ensure a sufficient speed in the mobile data network. This makes a theoretical downstream speed of 42.2 megabits per second in the UMTS network possible. Naturally, features like NFC (near-field communication), Bluetooth 3.0 and GPS are a must. According to the spec sheet, the main Wi-Fi module supports 802.11 b/g/n standards. However, a reader pointed out the 5 GHz capability according to standard 802.11 a. We often noticed that the Wi-Fi module had problems reconnecting to a previously identified access point during the test period. This can only be remedied by manually deactivating and reactivating the Wi-Fi module. We did not experience any problems with other access points during our tests.
The installed GPS module connects within a few seconds indoors when standing next to a window. The accuracy increases outdoors and in "line of sight". We did not ascertain any unexpected connection interruptions in our test scenario.
Nexus4，提供一系列的通信模块。高端的设备甚至体育虽然既不也不LG谷歌指定的LTE芯片。因此，该芯片被禁用，并且不能用于（在德国）。然而，确保有足够的速度在移动数据网络的HSPA +42模块安装在。这使得理论下行速率42.2兆比特每秒UMTS网络中的可能。当然，NFC（近场通信），蓝牙3.0和GPS等功能是必须的。根据规格表，主要的Wi-Fi模块支持802.11 B / G/ N标准。然而，读者指出，在5 GHz的能力，根据标准的802.11 a。我们经常发现，Wi-Fi模块重新连接到以前发现的接入点的问题在测试期间。这只能补救手工关闭或重新激活的Wi-Fi模块。在我们的测试中，我们没有遇到任何问题，与其他接入点。
安装的GPS模块连接站在旁边的一个窗口时，在几秒钟内，在室内。增加户外和“视线”的准确性。我们没有确定是否有任何意外的连接中断，在我们的测试场景。
Cameras & Multimedia
On behalf of Google, LG installs two camera modules in the Nexus 4. The primary camera alongside a flash is on the back and features a resolution of 8 megapixels. The front-facing camera can be used as a webcam for video calls via Skype. It features a fairly low resolution of 1.3 megapixels. Both cameras can record videos in Full HD quality. The front-facing camera achieves a resolution of 720p (1280 x 720 pixels) and the primary camera records in 1080p (1920 x1080 pixels). The primary camera's small sensor responds with slightly blurred details to moderate indoor light. Many cameras have great difficulties reproducing badly illuminated objects. This is often reflected in heavy image noise. The 8 megapixel sensor delivers a decent picture although the entire representation is much darker than that of the reference camera. Like most front-facing cameras, the picture quality is unfocused and too low to take snapshots. The primary camera shoots good outdoor pictures. The focus is compelling and the brightness deviation decreases compared with the reference camera.
相机及多媒体
代表谷歌，LG两个相机模块安装在Nexus4。旁边一个闪光灯的主摄像头的背面，设有一个8百万像素的分辨率。通过Skype作为一个摄像头用于视频通话的前置摄像头可用于。它拥有一个相当低的分辨率为1.3百万像素。两款相机可录制全高清质量的视频。前置摄像头达到了分辨率为720p（1280 x 720像素）和1080P（1920 X1080像素）的主摄像头记录。主摄像头的小型传感器响应稍微模糊的细节，室内光线适中。许多相机有很大的困难，音响严重照明对象。这往往体现在重型图像噪声。虽然整个表示暗很多比参考摄像机，800万像素的传感器提供了一个体面的画面。像大多数面向前方的摄像机，图像质量是重点不突出，和过低的拍摄快照。主摄像头拍摄良好的户外写真。是引人注目的焦点与参考相机相比，亮度偏差减小。
Photo Sphere
Almost every smartphone now features an 8 megapixel camera sensor. To stick out from the masses, Google installs a nifty feature in its newest Android version. "Photo Sphere" enables taking pictures in a 360° panorama shoot by lining up several frames. The result surprised and awed us at the same time. Great pictures were possible right away and it was easy in contrast to taking such a panorama shoot with a digital SLR camera. It feels like you are standing in the middle of a room and can see every angle of the object when viewing the 360° panorama in Android's standard gallery.
照片球
现在几乎所有的智能手机拥有一个800万像素的摄像头传感器。要坚持从广大人民群众，在其最新的Android版本谷歌安装了一个漂亮的功能。 “照片球”使拍照360°全景拍摄的排队几帧。惊讶和敬畏的结果，我们在相同的时间。大图片，并马上很容易对比与数码单反相机拍摄的全景。这感觉就像你站在中间的一个房间，可以看到每一个对象的角度观看时的360°全景Android的标准图库。
Accessories
We have gotten used to the fact that manufactures not always overwhelm us with a diversity of accessories. This supposition was again confirmed since the included accessories are very sparse. Besides the smartphone, we only found a modular power supply and a quick start guide in the box. Regrettably, Google does not even include a headset for its bestseller. However, it is also questionable whether the customer can demand that in view of a current price of EUR 349 for the 16 GB version.
Google touts the Nexus 4 with the option of recharging the device without any charging cords. An optional, inductive charging mat on which the Smartphone is placed is required for that. A compatible, third-party charger is available for EUR 49.99.
Warranty
Google offers a 12 month warranty period. The buyer can take advantage of an additional 12 month warranty after the warranty expires.
饰品
我们已经习惯了这样的事实，制造商并不总是压倒我们的多样性配件。再次证实这种假设，因为所包括的配件非常稀疏。除了智能手机，我们只发现了一个模块化电源和包装盒中的快速入门指南。令人遗憾的是，谷歌甚至不包括其最畅销的耳机。然而，这是否也值得商榷，顾客可要求，鉴于当前的价格349欧元，16 GB的版本。
谷歌宣称的Nexus4的选项没有任何充电线充电设备。是必需的，一个可选的，感应充电智能手机放在垫子上。兼容的，第三方充电器是49.99欧元。
保
谷歌提供了一个12个月的保修期。买方可以利用一个额外的12个月的保修期，在保修期满后。
Input Devices & Controls
A capacitive touchscreen that responds to simultaneous use of ten fingers is used for inputting. All touches are implemented accurately and quickly. The device also copes with all kinds of touch gestures. The default Android keyboard is preinstalled. Owing to the large 4.7 inch screen, the touch keys are sufficiently sized to ensure accurate typing. The keyboard often covers small screens by far over 50% in landscape mode. This is not the case in the Nexus 4. The Galaxy S3 and iPhone 5 still rely on a physical home button. The Nexus range now omits this button and only uses touch control on the screen. The three touch buttons "back", "home" and "multitasking" rotate along with the screen by 90° in landscape mode. This also means that approx. 5 millimeters of the screen are always "lost". We think that the competition's concept, such as that of Samsung's Galaxy range, makes more sense. The main navigation buttons are outside the touchscreen.
响应十个指头同时使用的电容触摸屏，用于输入。所有涉及准确，迅速地实施。该器件还应对各种触摸手势。默认的Android键盘预装。由于4.7英寸的大屏幕，触摸按键有足够的大小，以确保准确的打字。键盘往往占地面积小屏幕在横向模式下远远超过了50％。这不是在Nexus4的情况下。银河S3和iPhone5仍然依赖于一个物理的主页按钮。现在的Nexus系列省略了此按钮，仅在屏幕上，采用触摸控制。三个触摸式按键“返回”，“家”和“多任务”旋转与屏幕在横向模式下90°。这也意味着，约。 5毫米的屏幕总是“丢失”。我们认为，竞争的概念，如三星的Galaxy系列，更有意义。主导航按钮之外的触摸屏。
Display
A resolution of 1280 x 768 pixels in a 4.7 inch screen is not the measure of all things. The screen would have to provide more than the actual 320 ppi to secure itself a place in the premium sector (iPhone 5: 326 ppi). But that is complaining on a high level. In return, the screen in the Nexus 4 impresses with rich color reproduction. The average brightness of 275.3 cd/m² is at most enough for a place in the upper midfield. HTC's 8X (293.8 cd/m²) achieves slightly better rates but it is remote from the brilliant screen in the iPhone 5 (486.8 cd/m²). The illumination of 93% leads to a virtually homogeneous brightness distribution in every area and is on a consistently high level. Differences are not visible to the human eye. We recorded a black value of 0.24 cd/m² using the Gossen Mavo Monitor. This results in a very high contrast of 1179:1.
分辨率为1280 x 768像素，4.7英寸的屏幕是不是衡量一切事物。屏幕将提供超过320 ppi的实际，以确保自身在高端市场（iPhone 5的326 PPI）的地方。但是，抱怨在一个较高的水平。作为回报，在Nexus4的屏幕具有丰富的色彩再现令人印象深刻。 275.3坎德拉/平方米的平均亮度是足够的地方在上中场。 HTC8X（293.8坎德拉/平方米）小幅达到更好的利率，但它是远程从辉煌屏幕的iPhone 5（486.8坎德拉/平方米）。导致93％的照明亮度几乎均匀分布在各个领域和始终如一的高水平上。差异的人的眼睛是不可见的。我们记录了一个黑色的价值0.24坎德拉/平方米使用的戈森MAVO的监视器。这将导致在一个非常高的对比度为1179:1。

The device would benefit from a higher maximum brightness in outdoor use because the screen pane is very reflective. The high contrast alongside the high brightness compensates the reflections and enables viewing the content to a sufficient extent.
该设备将受益于更高的最大亮度在户外使用，因为屏幕的窗格是非常反射。旁边的高亮度高对比度补偿反射，使观看的内容到足够的程度。
This part of our reviews is consistently getting shorter owing to the In-Plane-Switching technology (IPS). The liquid crystal screen in Google's Nexus 4 is extremely viewing angle stable. The contrast and color fidelity are maintained up into the slightest angles.

Our test device exhibited a good to very good color accuracy. Red and magenta presented the strongest deviations but remained within the range with a DeltaE 2000 of approximately 5.
Performance
Google's Nexus 4 comes with a range of interesting hardware features. LG and Google have agreed upon the latest high-performance components. The SoC (system on a chip) is a Snapdragon S4 Pro model number APQ8064. It is built in a 28nm technology and works in accordance with the ARMv7 instruction set. The quad-core features a clock rate of 1.5 GHz and a 2 MB level 2 cache. One of the most forward-looking features is certainly the generously sized working memory. Competing models still rarely feature 2 GB. The graphics unit is just as well equipped. The Adreno 320 GPU ensures enough power for multimedia applications.
That much to theory. In contrast to the low supply in Microsoft's Windows Store, Google supplies enough synthetic benchmarks to attain a precise overview of the performance. On the whole, the Nexus 4 achieved throughout satisfactory results in the synthetic tests. In a direct comparison with the iPhone, the Cupertino model presented up to 5 fps less in GLBenchmark 2.5. The competitors from Samsung and HTC were also defeated in AnTuTu Benchmark v2. The flagships of the other manufacturers achieved an approximately 30% lower score. Surprisingly, Asus' Padfone 2 achieved considerably better scores in this and in the Linpack benchmark, although the same SoC is installed. In a smartphone comparison, the Nexus 4 manages its way to the top ranks in the synthetic benchmarks.
谷歌的Nexus4配备了一系列有趣的硬件功能。 LG和谷歌已经同意后，最新的高性能组件。该SoC（片上系统）了Snapdragon S4 Pro的型号APQ8064。它是建立在一个28nm技术，并按照ARMv7指令集。四核具有一个时钟速度为1.5 GHz，2 MB二级高速缓存。最具前瞻性的特点之一肯定是宽敞的工作记忆。竞争机型仍然很少配备2 GB。图形单元一样装备精良。了Adreno320 GPU，确保足够的电力供多媒体应用。
那么多理论。在低电源在微软的Windows应用商店，谷歌提供足够的合成基准的表现获得准确的概述。就整体而言，在Nexus4，取得了综合测试整个令人满意的结果。在直接与iPhone相比，Cupertino的模型提出了GLBenchmark2.5少5幅。竞争对手三星和HTC也被击败在AnTuTu的基准V2。其他厂商的旗舰达到降低约30％的得分。令人惊讶的是，华硕的PadFone2取得更好的成绩相当，在这方面及Linpack基准测试，虽然安装了相同的SoC。的Nexus4智能手机的比较，管理方式的合成基准顶尖行列。

The score does not look quite as good in the browser-based performance tests. Our test device provided a lower score than Samsung's Galaxy S3, Asus' Padfone 2 or Apple's iPhone 5 in all tests. As usual, the small exception is Google's V8 v7. The Nexus 4 achieved a 43% better score than HTC's 8X. But that is unfortunately not enough to reverse the rather low score.

We used AndroBench 3 for the last part of our test series. It assesses the flash memory's write and read performance rates. The Nexus 4 almost managed 50 MB/s in sequential read of 256 KB files. Neither Asus' Padfone 2 nor the Galaxy S3 did a better job here. The difference is even clearer in sequential write.

Portable devices are getting bigger and the screen resolution higher. Thus, using the smartphone as a multimedia player would be the obvious thing to do. However, the higher the resolution the more work the SoC has with playing Full HD videos. Many low-performance smartphones do not achieve more than 25 frames per second. We used the trailers from the movies James Bond: Skyfall and Transformers 3: Dark of the Moon in Full HD quality for the test. The hardware has enough capacity to render everything easily.
便携式设备正在变得更大，更高的屏幕分辨率。因此，使用智能手机作为多媒体播放器将是显而易见的事情。然而，较高的分辨率，更多的工作SoC具有播放全高清视频。很多低性能的智能手机没有达到每秒25帧以上。我们用拖车从电影中詹姆斯·邦德：SKYFALL变形金刚3：黑暗的月亮在全高清画质的测试。硬件有足够的容量，轻松呈现一切。
Games
This is similar for the games assortment in the PlayStore. We did not find any 3D games that were a problem for the Nexus 4. For example, GTA III did not even push the device to the maximum temperatures that we ascertained in the "Temperature" part of this review. 2D games, like the popular Angry Birds, will consequently run smoothly.
这是类似PlayStore的游戏品种。我们没有找到任何的3D游戏，是一个问题的Nexus4。例如，GTA III甚至没有设备推到最高温度，我们确定在“温度”检讨的一部分。 2D游戏，如流行的愤怒的小鸟，会因此而顺利运行。
Sound Quality
The speech quality is tested based on several test calls in different surroundings. The called party could hear us well in all situations and perceived our call as clear and intelligible. The maximum volume is high enough to make calls from the passenger seat in a car. We were also satisfied with the performance of the installed hands-free equipment and its sufficient volume.
语音质量测试的基础上在不同的环境中的几个测试呼叫。被叫方可以听到我们在所有情况下，清楚和易于理解和感知我们的呼吁。最大音量是高到足以使在一辆汽车的乘客座位的呼叫。我们也与安装免提设备和足够量的表现感到满意。
Emissions
Temperature
The passively cooled smartphone achieved a maximum temperature of 43.2 degrees Celsius in the screen's upper center area during full GPU and CPU load. This is a temperature difference of nearly 11 degrees to the devices lower left area. However, we never managed to push the Nexus 4's temperatures to the specified rates because the performance reserves will usually never be completely exhausted, except in the full load simulation. The smartphone's maximum idle temperature is 37.9 degrees Celsius, so when used for occasional Internet browsing, making calls and no computing-intensive tasks are performed. The temperatures never climbed to a concerning rate or made working with the device impossible during the course of our tests. The power supply's maximum temperature of 37.9 degrees Celsius is also within an acceptable range.
Update: The idle temperatures of the Nexus 4 are very dependent on background tasks. The idle temperatures reach the above mentioned rates after initial Smartphone setup. After that, 27 - 31°C are usually measured without load.
温度
被动冷却的智能手机实现的最高温度摄氏43.2度，在屏幕的上部中心区域在完整的GPU和CPU负载。这是近11度的设备的左下区域的温度差。但是，我们从来没有成功的Nexus4的温度推到指定的利率，因为性能储备将通常不会被完全耗尽，除了在满负荷仿真。智能手机的最大的闲置温度为摄氏37.9度，所以在使用时偶尔上网浏览，拨打电话并没有计算密集型任务的执行。的温度没有爬过的关于速度，或使用我们的测试过程中的移动设备是不可能的。电源供应器的最高温度为摄氏37.9度也是在一个可接受的范围之内。
更新的Nexus4的闲置温度都非常依赖于后台任务。最初的智能手机安装后，空闲温度达到上面提到的价格。在此之后，27 - 31°C通常无负载测量。
(±) The maximum temperature on the upper side is 43.2 °C / 110 F, compared to the average of 35.1 °C / 95 F, ranging from 21.9 to 63.7 °C for the class Smartphone.
(±) The bottom heats up to a maximum of 42.3 °C / 108 F, compared to the average of 33.9 °C / 93 F
(±) In idle usage, the average temperature for the upper side is 34.7 °C / 94 F, compared to the device average of 32.8 °C / 91 F.
Speakers
The device's sole speaker for playing music is located on the back. Regrettably, it cannot serve with a rich and clean sound. The sound turns very tinny and bland at approx. 60% of maximum volume. The speaker virtually neglects lower pitches. The sound overdrives and becomes unpleasant when the volume is increased even more. Because the back of the device is sleek and flat, the speaker is completely covered when the Nexus 4 is placed on an even surface. This very audibly reduces the maximum volume and the sound is distorted.
该器件的唯一喇叭播放音乐是位于背面。遗憾的是，它不能成为一个丰富而干净的声音。大约原来非常尖细，平淡的声音。最大音量的60％。扬声器几乎忽略了较低的球场。声音过驱动和音量时更增加变得愉快。由于该设备的背面是光滑和平坦的，扬声器被完全覆盖时的Nexus4放置在平坦的表面上。这非常可听地降低最大音量和声音失真。
Energy Management
Power Consumption
To extend the time between two battery recharges, it is advisable to keep the power consumption low and not use power-guzzling applications. The Nexus 4 is satisfied with 0.7 to 1.4 watts in idle mode. The screen should be manually set to its minimum brightness and the wireless modules should be disabled to achieve a consumption of only 0.7 watts. The consumption is twice as high with 1.4 watts when the maximum brightness is used and the Wi-Fi module is on. We have to note that the SoC was not fully loaded, so computing-intensive programs were not running in the foreground. The power consumption climbs to 3.9 watts when the quad-core is loaded using the Classic mode of the Android app Stability test. The consumption climbed to the maximum of 6.5 watts when we added simulated GPU load. Samsung's Galaxy S3 consumes a maximum of 3.4 watts and the battery reference from Cupertino is satisfied with only 2.9 watts.
耗电量
延长两个电池充电之间的时间，最好是保持低功耗，功耗高耗能的应用，而不是使用。 0.7至1.4瓦，在空闲模式下的Nexus4是满意的。屏幕应手动设置其最小亮度应禁用无线模块，实现了消耗仅为0.7瓦。消耗1.4瓦的最大亮度时使用的Wi-Fi模块是高两倍。我们必须注意的SoC满载，所以计算密集型程序没有在前台运行。攀升至3.9瓦功耗四核时，使用经典模式的Android应用程序稳定性试验加载。攀升至6.5瓦的最大消费时，我们增加了模拟GPU的负载。三星的Galaxy S3的最大功耗为3.4瓦，电池参考从苹果感到满意，只有2.9瓦。

Battery Runtime
The non-removable battery lasted for 2 hours and 36 minutes before it had to be recharged in the aforementioned full load scenario with a consumption of 6.5 watts. Despite its lower power consumption, an iPhone 5 does not last much longer (2 hours and 2 minutes). The Reader's test is closer to reality. The brightness was manually set to 150 cd/m², the Wi-Fi module was on and a script continuously opened Internet sites. We ascertained a runtime of 7 hours and 20 minutes in this scenario. The Nexus 4 is defeated. Although the Galaxy S3 also sports a 2100 mAh lithium ion battery, it lasts an hour longer without the charging cord. Both smartphones however are beaten by the endurance behemoth iPhone 5. It sets the standard extremely high with almost 16 hours in the Reader's test.

Verdict
Google has demonstrated its skills as a hardware manufacturer in the recent past and convinced with very good performance in the tablet sector. Both Google's Nexus 10 and Nexus 7 delivered a throughout remarkable performance. The smallest device from the latest Nexus family can seamlessly connect to this performance. Its build is compelling and we like the design despite its plain black color. The WXGA (1280 x 768 pixels) IPS screen's average brightness of 275.3 cd/m² is much lower than the iPhone 5's Retina screen. It is nevertheless enough to easily display content outdoors. All common wireless modules and interfaces are available apart from the omitted micro-SD slot. The battery also can be recharged via an optionally available induction charger. The eager multimedia user does not have to worry about the performance getting tight. Neither playing Full HD videos nor sophisticated 3D games push the SoC and its 2 GB of working memory to the limits. The primary camera's quality also presented a good result in our tests and the innovative "Photo Sphere" software feature earns a bonus point. The battery runtime is noticed adversely. Both the Galaxy S3 and iPhone 5 do a better job. We can only hope that the battery runtime will be increased via Google's excellent software update policy.
Altogether, Google's Nexus 4 (made by LG) is a promising device. The premium smartphone only marginally misses "Very Good". Problems with reconnecting to an existing Wi-Fi network are annoying in practice and will hopefully be eliminated by a software update. We not only find the hardware but also the price compelling. Such a high-end smartphone fused with guaranteed updates to the latest Android version for EUR 299 (8 GB version) or EUR 349 (16 GB version) will certainly be a challenge for the competition.
谷歌已经展示了它的技能作为一个硬件制造商在最近的过去，相信在平板电脑行业有非常不错的表现。谷歌的Nexus10和Nexus7发表了整个表现可圈可点。从最新的Nexus系列最小的设备可以无缝连接，以这样的表现。它的构建是引人注目的，我们喜欢的设计，尽管其纯黑色的颜色。 WXGA（1280 x 768像素）的IPS屏幕的平均亮度为275.3坎德拉/平方米远低于Retina屏幕的iPhone 5。但它仍然是足以轻松户外显示内容。所有常见的无线模块和接口，除了省略的micro-SD插槽。该电池还可以通过一个可选的感应充电器充电。渴望多媒体用户不必担心表现越来越紧。无论是播放全高清视频，也没有复杂的3D游戏推SoC和2 GB的工作记忆的限制。主摄像头的质量也提出了很好的结果，在我们的测试和创新的“照片球”软件功能赢得奖金点。电池运行时注意到不利影响。银河S3和iPhone5做一个更好的工作。我们只能希望通过谷歌的优秀的软件更新政策将增加电池的使用时间。
总之，谷歌的Nexus4（LG）是一种很有前途的设备。溢价智能手机只能勉强错过“非常好”。重新连接到现有Wi-Fi网络的问题在实践中很烦人，将有望被淘汰的软件更新。我们不仅可以找到硬件，但价格也引人注目。这样的高端智能手机融合，保证更新到了最新的Android版本为299欧元（8 GB的版本）或349欧元（16GB版）肯定会有竞争的挑战。
