诺基亚 Lumia 820 智能手机测评
Editor's Note (January 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.
Nokia's influence as a market leader in the mobile sector has ebbed over time. One reason for this was the belated break with its outdated Symbian operating system for an alternative. Now Microsoft relies on a select group of manufacturers for launching Windows Phone 8, to whom Nokia belongs alongside Samsung and HTC. Unlike the competition, Nokia focuses solely on Microsoft's newest operating system and thus wants to regain its former superiority.
Nokia places the Windows Phone 7.5 based Lumia 800 successor between its premium model Lumia 920 and the entry-level Lumia 620 device. Thus, the midrange Lumia 820 smartphone has to compete against HTC's 8X. To achieve this, Nokia packs a few features into the Lumia 820, which the Lumia 920 already presented. For example, the primary camera from Carl Zeiss though only with a 5 megapixel resolution alongside a dual LED flash, a few proprietary apps, a PETA band LTE module and a high-def 4.3 inch AMOLED screen featuring 217 ppi. Moreover, 8 GB of flash memory are available, which can be expanded up to 64 GB via a micro SD card. Nokia currently charges EUR 499 (RRP) for this bundle. Is it justified? To find out, we sent Nokia's Lumia 820 through our exhaustive test course.
编者注（1月20日，2013年）：下面的检讨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。
诺基亚在移动领域的市场领导者的影响力已经消退，随着时间的推移。原因之一是迟来的突破过时的Symbian操作系统的替代。现在微软依赖于一组选定的厂商推出的Windows Phone8，诺基亚属于三星和HTC一起。竞争不同的是，诺基亚只专注于微软最新的操作系统，因此想重拾昔日的优势。
诺基亚的Windows Phone7.5基于Lumia 800的继任者之间的溢价模型的Lumia920和入门级的Lumia620设备。因此，中端的Lumia820智能手机，HTC的8X抗衡。为了实现这一目标，诺基亚包到的Lumia820，其中的Lumia920已经提出了一些功能。例如，从卡尔蔡司主摄像头虽然只有500万像素的旁边了双LED闪光灯，几个专有的应用程序，PETA的频段LTE模块和高清晰度4.3英寸的AMOLED屏幕，具有217 ppi的分辨率。此外，8 GB的快闪记忆体，可通过micro SD卡可扩展到64 GB。诺基亚目前这种捆绑收费499（RRP）欧元。它是有道理的吗？为了找到答案，我们派出了诺基亚的Lumia820，通过我们详尽的测试场。
Case
A stylish basic could also be a fitting name for our test device. The non-slip, matte-black coated rear shell is made of rigid polycarbonate and can be swapped with white, blue, red, yellow, purple and gray covers. In contrast to the Lumia 920's unibody design, the Lumia 820's chassis is divided. The exchangeable 1650 mAh battery can be accessed when the lightly rounded rear cover is removed. The slots for a micro SIM and micro SD card is beneath that. The casing's shape is nice to hold and reminds us of HTC's Mango-based Titan (Windows Phone 7.5) which featured the same build but in an aluminum chassis. The Lumia 820 makes a very stable impression despite the prevalent plastic.
The casing can only be warped marginally even when high force is applied. The device is comfortable to hold, which is due to its pleasant feel with the rounded forms as well as the high weight of just below 160 grams. The dimensions of 123.8 x 68.5 mm (w x d) at a height of 9.9 mm do not look fragile but a screen size of 4.3 inches has to be accommodated. HTC's 8X looks much less bulky and although it features almost the same size (132.4 x 66.2 x 10.2 mm), it weighs 30 grams less - not to mention the much slimmer and smaller iPhone 5. These massive differences suggest a backlog in development compared with experienced manufacturers. However, it could also be an attempt to stick out from the competition.
时尚的基础，为我们的测试设备也可能是一个合适的名字。防滑，磨砂黑色涂层后壳制成的硬质聚碳酸酯与白色，蓝色，红色，黄色，紫色和灰色盖可以互换。相反的Lumia920的一体式机身设计，Lumia820的机箱被分成。轻轻圆润的后盖被删除时，可更换的1650毫安时的电池，可以访问。为微SIM卡和micro SD卡插槽下方。外壳的形状是很好地去把握和让我们想起HTC的芒果的Windows Phone7.5（泰坦）精选相同的构建，但在铝机箱。 Lumia820的一个非常稳定的印象，尽管流行的塑料。
套管只能是扭曲甚至轻微高力施加。该设备是舒适举行，这是由于其愉快的感觉，圆润的形式以及高重量低于160克。尺寸为123.8 x68.5毫米（宽X深）在9.9毫米的高度不显得脆弱，但可容纳4.3英寸屏幕尺寸。 HTC的8X看起来不太笨重，虽然它的功能几乎相同的尺寸（132.4所述66.2×10.2毫米），重量为30克 - 更不用提更苗条，更小的iPhone 5。这些巨大的差异表明了积压在发展比较有经验的制造商。然而，它也可能是企图坚持从竞争。
Connectivity
Nokia's Lumia 820 is only available in one flash memory version. Unlike the Lumia 920 premium model however, the 8 GB flash memory in our test device can be expanded up to 64 GB via micro SD cards. The potential buyer should order one right away because only around 5 GB of the 8 GB are really useable. Microsoft additionally offers 7 GB of online storage in the cloud via SkyDrive.
As to interfaces, Nokia also follows the minimalistic standard of the genre. The 3.5 mm jack on the casing's upper edge allows connecting the included in-ear headset and enhances the sound via the Dolby headphone. Data sharing is possible via the micro USB port on the smartphone's lower edge. The Lumia 820 is also charged over this port. Nokia optionally offers a replacement cover that enables wireless charging.
诺基亚的Lumia820是唯一可在一个闪存版本。不同的Lumia920溢价模型，但是，在我们的测试设备8 GB快闪记忆体可扩展到64 GB通过Micro SD卡。潜在买方应下令一个正确的了，因为只有大约5 GB，8 GB真的可用。另外，微软还提供7 GB的在线存储空间，通过SkyDrive在云中。
至于接口，诺基亚也遵循简约的标准的流派。外壳的上部边缘上允许的3.5毫米插孔连接附带的耳塞式耳机，提高了声音通过杜比耳机。数据共享是可能通过微型USB端口智能手机的下缘。 Lumia820的充电也通过此端口。诺基亚可以提供更换盖板，使无线充电。
Software
Microsoft's Windows Phone 8 operating system powers the Lumia 820, which we previously examined in the review of HTC's 8X. The user interface is the same on every device and the smartphone manufacturer cannot modify it. The animated tile surface might be a matter of taste, but we find it very appealing. Its use is intuitive and clearly arranged. The only option for the manufacturer to individualize the software is to install self-developed apps.
The Lumia 820 comes with the usual bloatware (e.g. sports app, news app, hotel search app, etc.), but they fortunately not get out of hand. Of course Nokia did not miss the opportunity of installing many proprietary apps. Among others, we find Nokia Drive Beta+ free navigation app (the corresponding maps comes from Navteq) and Nokia Maps. With exception of Google Maps, similar apps from iOS or Android are usually very expensive. Comprehensive support software dubbed Nokia Care is also installed. All proved to be very well-developed apps that worked reliably in the practical tests.
Communication & GPS
As to the communication options, the test device is in no way inferior to the Lumia 920. The fast 802.11 a/b/g/n Wi-Fi standard is also implemented in the Lumia 820, which enables transmissions in both the 2.4 and 5 GHz frequency range. The connection worked very reliably even with a few rooms between the device and the router. GSM, including support for the four main frequencies (850, 900, 1800 and 1900 MHz), Edge, HSPA+ (UMTS / 3G) and PETA band LTE. Unlike the iPhone 5, Nokia's Lumia 820 does not only support Long Term Evaluation (LTE) via the German Telecom, but all 4G frequencies available in Germany. The SIM card slot underneath the battery accepts micro SIM cards. A compulsory Bluetooth module is also installed, though in the somewhat outdated 3.0 +EDR version. Besides that, Nokia installs a NFC chip (Near Field Communication) in the Lumia 820, which is not yet widely distributed in Germany. Moreover the Lumia 820 communicates with position satellites via A-GPS and Glonass. The test device exhibited a stable connection quality, which was very good outdoors and barely deteriorates indoors, as already the Lumia 920. Its accuracy is also high.
Telephony
The telephone tile is at the home screen's top left in the Windows Phone 8 default settings. Like all tiles, its size can be modified or it can be deleted when preferred. An alphabetically ordered app list, which also includes the telephone app, appears when wiping to the left. The handling is intuitive and the functions are available to the same extent as known from other operating systems. In addition to the number pad, the user can also access personal contacts, a search field or the mailbox here. Convenient: Numbers displayed in an email or browser window can be directly called without having to awkwardly copy and paste them in the telephone app.
Cameras & Multimedia
Nokia installs an 8 megapixel, or 3264 x 2448 pixel primary camera alongside a dual LED flash in the Lumia 820. The Lumia 820 also features autofocus. It can conveniently be accessed over the dedicated camera button on the casing's right and features two very palpable pressure points. The camera is triggered when it is kept pressed in standby. A short tap is enough when it is on. Nokia uses a Tessar objective from the renowned brand Carl Zeiss as the lens. The fixed aperture value is f2.2 at a focal length of 26 mm. A x4 zoom slightly enlarges distant objects but also increases the image noise. This also occurs when the minimum focal range of 10 cm to the object is undercut. Videos can be recorded in Full HD (1080p) with 30 frames per second and are good in sufficient brightness. The flash can be added here when necessary. The diverse settings have been completely adopted from the Lumia 920 premium model. Regrettably, a menu point for directly selecting the image quality has also been omitted. Nevertheless, options like ISO and exposure values or picture mode are appealing. The camera makes good pictures in an appealing quality providing that the ambient light is sufficient. Depending on the setting, the LED flash is automatically enabled and reduces the image noise. According to Nokia, the LED illuminates objects up to a distance of 3 meters, which we could almost confirm in our tests. Nevertheless, it does not completely prevent image noise. Pictures drift into a distinct warm hue with slightly distorted colors in artificial light.
The front-facing camera has noticeably been slimmed in comparison with the Lumia 920. It merely features a low VGA resolution of 0.3 megapixels, which is simply no longer up-to-date. The picture quality in the test was below average. Focused pictures were not possible even after several attempts and the image noise is disproportionately visible. The front-facing camera is at most suitable for the occasional video chat in good light.
软件
微软的Windows Phone 8操作系统的Lumia 820，这是我们以前研究在回顾HTC的8X。每个设备上的用户界面是一样的，智能手机制造商不能修改它。动画瓷砖表面可能会是一个品味的问题，但我们觉得它非常有吸引力。其采用的是直观的，有明确安排。个性化的软件的制造商是唯一的选择，安装自主研发的应用程序。
的Lumia 820与通常的臃肿软件（酒店搜索应用程序，应用程序，如体育新闻的应用程序，等等），但幸运的是，他们不不可收拾。当然，诺基亚没有错过安装许多专有的应用程序的机会。其中，我们发现诺基亚硬盘测试版+免费导航应用程序（相应的地图是从Navteq）和诺基亚地图。随着谷歌地图，类似iOS或Android的应用程序的异常通常是非常昂贵的。被称为诺基亚客户服务的全面支持的软件也被安装。所有被证明是非常发达的应用程序，在实际的测试工作可靠。
通信与GPS
通信选项，测试设备是丝毫不逊色的Lumia 920。快速802.11 A / B / G / N Wi-Fi标准的Lumia 820，从而使传输在2.4和5 GHz频率范围内也实行。即使有几间房设备和路由器之间的连接工作非常可靠。 GSM，包括四个主要的频率（850，900，1800和1900 MHz），边缘，HSPA +（UMTS / 3G）和PETA频段LTE的支持。不同的是iPhone 5，诺基亚的Lumia 820不支持通过德国电信的长期评价（LTE），但在德国所有的4G频率。 SIM卡插槽在电池的下面接受微型SIM卡。一个强制性的蓝牙模块也安装了，虽然有点过时的3.0 + EDR版本。除此之外，诺基亚的Lumia 820，这是尚未广泛分布在德国安装了NFC芯片（近距离通信）。此外，Lumia 820的位置通过A-GPS和GLONASS卫星通信。测试设备表现出稳定的连线品质，这是很不错的户外和室内几乎没有恶化，已有的Lumia 920。其精度也很高。
电话
电话瓷砖在Windows Phone 8的默认设置是在主屏幕的左上角。像所有的瓷砖，它的大小可以修改或首选时，可以将其删除。按字母顺序排序的应用程序列表，其中还包括电话应用程序，擦拭时出现的左侧。处理是直观和功能都可以从其他操作系统相同程度。除了数字键盘，用户也可以访问的个人联系人，搜索字段的或这里的邮箱。方便：一封电子邮件或浏览器窗口中显示的数字，可以直接调用，无需笨拙复制并粘贴在电话应用程序。
相机及多媒体
诺基亚安装一个800万像素，3264×2448像素的主摄像头，双LED闪光灯的Lumia 820一起。的Lumia 820还具有自动对焦。它可以方便地访问专用相机外壳的右边的按钮，并设有两个非常扪的压力点。相机被触发时，它保持待机状态下按下。一个简短的自来水时，它是足够的。诺基亚采用了Tessar的目标从知名品牌卡尔·蔡司镜头。固定光圈值为F2.2的焦距为26毫米。一个x4变焦略有放大远处的物体，但也增加了图像噪声。这也发生，当最小焦距范围为10厘米的物体被削弱。画可以与每秒30帧的记录，可在全高清（1080）在足够的亮度，是很好的。闪光灯可以添加必要时。多样的设置已经完全采用的Lumia 920溢价模型。令人遗憾的是，菜单中直接选择图像质量也被省略。然而，ISO和曝光值或图像模式的选择，如呼吁。相机会提供一个有吸引力的质量，环境光线充足的好照片。根据设置，LED闪光灯，自动启用和降低图像噪声。据诺基亚LED照亮物体的距离为3米，在我们的测试中，我们几乎可以确认。然而，它并不能完全防止图像噪声。图片漂在人工光的颜色稍微扭曲成一个独特的温暖色调。
前置摄像头的Lumia 920相比明显瘦身。它只是具有低的VGA分辨率的0.3百万像素，这简直是不再日期。在测试中的画面质量低于平均水平。聚焦的图片是不可能的，即使在多次尝试后，图像中的噪声是不成比例可见的。是最适合在良好的光线，偶尔视频聊天的前置摄像头。
Accessories
The customer gets the usual accessories for Nokia's Lumia 820 at a current street price of EUR 400. Besides the smartphone and the 1650 mAh battery, there is a user's manual, USB cable with the corresponding charger and an in-ear stereo headset alongside three alternative ear plugs in the colorful box. Other accessories are commended on Nokia's product page. For example, rear shells in diverse colors and some that enable wireless charging, as well as the corresponding charging cradle. The Lumia 820 even works with the charging pillow from the beanbag chair manufacturer Fatboy. Moreover, Nokia entered a prestigious collaboration with the well-known accessories manufacturer Monster and offers a Bluetooth headset matching to the smartphone.
Warranty
Opposing the trend, Nokia includes a 24 month warranty on the Lumia 820. The battery and accessories are covered for 12 months. Strangely, the charger is excluded and is only protected for 6 months.
饰品
客户得到常用配件诺基亚的Lumia820，在目前的零售价400欧元。除了智能手机和1650毫安时的电池，有一本用户手册，USB数据线与相应的充电器，在色彩缤纷的方块旁边三个替代耳塞入耳式立体声耳机。其他配件是诺基亚的产品页面上赞扬。例如，后壳在不同的颜色和一些启用无线充电，以及相应的充电底座。甚至可与Lumia820的充电枕头豆袋椅制造商肥仔。此外，诺基亚与知名配件制造商的怪物，并进入一个著名的合作提供了一个蓝牙耳机，智能手机相匹配。
保
反对的趋势，诺基亚的Lumia820包括一个24个月的保修。覆盖12个月的电池和附件。奇怪的是，充电器被排除在外，仅6个月保护。
Input Devices & Controls
Inputting text via a virtual QWERTY keyboard needs a bit of practice because of the cramped key field. But after that, it is a piece of cake. The slightly wider keys in landscape mode enhance the positive impression even more. Regrettably, Nokia does not completely use the available room and the key layout remains unaltered. We adversely noticed that approximately two thirds of the available room is taken up from the on-screen keyboard in landscape mode so that the displayed screen is very small. The address bar is positioned directly above the keyboard when using Internet Explorer and facilitates one-handed use. The automatic screen rotation when turning the smartphone is implemented quickly. Using the touchscreen is overall smooth and precise; fingers glide with agreeable ease over the glass surface.
通过一个虚拟的QWERTY键盘输入文字，需要一点点的做法，因为局促的关键领域。但在那之后，它是一块蛋糕。按键在横向模式下稍宽提升积极的印象，甚至更多。令人遗憾的是，诺基亚并没有完全使用可用房间的按键布局保持不变。我们不利注意到，约三分之二的可用房间是采取了从屏幕上的键盘，这样在横向模式下显示的画面是非常小的。地址栏直接定位在键盘上方，使用Internet Explorer时，方便单手使用。自动屏幕旋转时，打开智能手机的迅速落实。使用触摸屏是整体的平稳和精确的手指滑向同意容易在玻璃表面。
The Lumia 820's screen dubbed "ClearBlack AMOLED" by Nokia features a 15:9 aspect ratio at a screen diagonal of 4.3 inches (10.9 cm) and has a resolution of 480 x 800 pixels. Nokia builds in a contrast-enhancing polarization filter and an ambient light sensor that automatically adjusts the brightness when enabled. The casing does not stick out on the screen's edges and leaves the screen's glass unprotected. The pixel density of 217 ppi was subjectively compelling in the test. However, contenders like HTC's Windows Phone 8X or Nokia's Lumia 920 easily surpass this rate with 342 ppi and 332 ppi respectively. Even Apple's iPhone 5 or Google's Nexus 4 clearly outperform the test device with 326 and 320 ppi.
The screen only places itself in the lower midfield with an average brightness of 297 cd/m² and a maximum of 318 cd/m². The device is superior to the maximum 283 cd/m² of Google's Nexus 4 but lags slightly behind the 293.8 cd/m² of HTC's Windows Phone 8X. The upper brightness ranks is still reserved by Apple's iPhone 5 with 486.8 cd/m². Even Nokia's Lumia 920 scores a much higher 321.9 cd/m². Regardless of that, Nokia's Lumia 820 supplies the same, very good brightness distribution of 89 percent as already the Lumia 920.
被称为“”诺基亚的ClearBlack AMOLED屏幕的Lumia820的屏幕对角线为4.3英寸（10.9厘米），并设有一个15:9的宽高比，分辨率为480×800像素。诺基亚建立在对比增强偏振过滤器和环境光传感器，可以自动调节亮度时启用。外壳不会在屏幕的边缘伸出，离开屏幕的玻璃未受保护的。 217 ppi的像素密度是测试主观引人注目。然而，像HTC的Windows Phone8X或诺基亚的Lumia920的竞争者很容易超过这个速度分别为342 ppi和332 ppi的。即使苹果公司的iPhone5或谷歌的Nexus4显然会优于326和320 ppi的测试设备。
在屏幕上只放置在较低的中间位置的平均亮度为297坎德拉/平方米，最大为318坎德拉/平方米。该设备是优于最大283坎德拉/平方米的谷歌的Nexus4，但稍稍落后于HTC的Windows Phone8X293.8坎德拉/平方米。上亮度队伍仍然保留苹果的iPhone5486.8坎德拉/平方米。即使是诺基亚的Lumia920的分数高得多的321.9坎德拉/平方米。不管，诺基亚的Lumia820提供的相同，89％的Lumia920已经很好的亮度分布。

Brightness Distribution: 89 %
Center on Battery: 288 cd/m²
Contrast: 28800:1 (Black: 0.01 cd/m²)
The theoretical black value of 0.01 cd/m² and a calculated contrast of 28800:1 for construction-related reasons is first rate. The OLED technology completely turns off pixels that are to remain black, which results in a very dark black. We notice a very focused picture, crisp and bright colors as well as a breathtaking contrast subjectively. A higher brightness would have enhanced this impression even more. Overall, a very good presentation from the Lumia 820.
黑色的理论值0.01坎德拉/平方米，计算出对比度28800:1与建筑有关的原因是一流的。的有机发光二极管技术完全关断保持黑色，这会导致一个非常深的黑色的像素。我们注意到一个非常专注的画面，清晰和鲜艳的色彩以及一个惊人的对比主观。更高的亮度会提高更是这样的印象。总体而言，一个非常好的介绍的Lumia820。
Theoretically, Nokia should be able to perfectly cope with outdoor use in view of a maximum brightness of 318 cd/m². However, the brightness could have been a bit higher considering the very reflective glass surface and thus ensure perfect legibility even in direct sunlight. Otherwise, the displayed content remained well readable even outdoors.
从理论上讲，诺基亚应该能够完美地配合在户外使用的最大亮度为318坎德拉/平方米。然而，亮度可以高一点，考虑反射玻璃表面，从而确保完美的清晰度，即使在阳光直射。否则，显示的内容保持良好的可读性，即使在户外。
Owing to the 4.3 inch screen's AMOLED technology, the viewing angles remain stable from every position. Restrictions are only experienced in unfavorable light. Otherwise color distortions or brightness losses do not occur even at extreme angles, as can be seen on our screenshot of a slanted view. However, the picture is a bit overexposed and is not really faithful. The viewing angle category does not give reason for complaint seen with the naked eye.
由于4.3英寸的屏幕的AMOLED技术，可视角度保持稳定，从每一个位置。限制只在不利的光线经历。否则，色彩失真或亮度损失不发生，即使在极端角度，我们倾斜视图截图上可以看到。然而，实际情况是有点曝光过度，是不是真的忠实。视角类别不给用肉眼看到投诉的原因。
Performance
Nokia's Lumia 820 is powered by the same unit as used in the Lumia 920. Qualcomm's Snapdragon S4 Plus MSM8960 dual-core processor with a clock frequency of 1.5 GHz and 1 GB of working memory enable high work speeds. Apps are opened quickly and use is always smooth. Thus, the test device operates on a par with Windows Phone 8 premium models, such as HTC's Windows Phone 8X or Nokia's big Lumia 920.
The browser benchmarks underpin this. Google's V8 benchmark recorded a score of 783 and places the device just behind HTC's Windows Phone 8X and Nokia's Lumia 920, both with 785 points. A score of 1758 points places the Lumia 820 in front of the Lumia 920 with 1194 points in Browsermark 2.0. However, it is surpassed by the Nexus 4 with 1839 points. The test device finished Sunspider 0.9.1 after 923.2 ms. The Lumia 920 needed 915.3 ms and the iPhone 5 finished after 935.4 ms. The result of 333 points in Peacekeeper's benchmark is on a par with the Lumia 920 (334 points).
诺基亚的Lumia820采用的Lumia920中使用相同的单位。高通的Snapdragon S4加MSM8960双核处理器的时钟频率为1.5 GHz，1 GB的内存工作实现高的工作速度。迅速打开应用程序和使用一帆风顺。因此，测试设备上运行的Windows Phone8超值的机型，如HTC的Windows Phone8X或诺基亚的大的Lumia920相提并论。
浏览器基准测试支撑。谷歌的V8基准录得783分，仅次于HTC的Windows Phone8X和诺基亚的Lumia920，与785点和放置设备。在前面的Lumia920的得分为1758分的地方的Lumia820 Browsermark2.0与1194点。但是，它超过了1839点的Nexus4。试验装置完成后的Sunspider0.9.1923.2毫秒。所需的Lumia920915.3毫秒，iPhone 5的935.4毫秒后完成。 333点，在维护和平的基准结果是上相提并论的Lumia920（334点）。

* ... smaller is better
The Lumia 820 scored well in the synthetic benchmarks. Our standard AnTuTu Benchmark v2 is currently not available for Windows Phone 8. However, the AnTuTu Benchmark v0.8.0 beta is only slightly different according to the developer. The Lumia 820 achieved a total score of 11644 points, which is right behind the 12281 points achieved by HTC's Windows Phone 8X. The other scores are very similar to those of the Lumia 920 and are impressive.
Lumia820的高分在合成基准。我们的标准将AnTuTu基准v2是目前没有可用的Windows Phone8。然而，将AnTuTu基准v0.8.0 beta是根据开发人员只是略有不同。 Lumia820的达到11644分的总成绩，这是正确的背后HTC的Windows Phone8X达到12281点。对方得分是非常相似的Lumia920和令人印象深刻。
Games
Qualcomm's SoC (system-on-a-chip) sports an Adreno 225 GPU for graphics. There still aren't many games available in the Windows Phone 8 store and particularly demanding 3D games are still scarce. We tested Angry Birds Star Wars, Flight Control, Plants vs. Zombies, Shoot 1UP and Need for Speed: Hot Pursuit on the Lumia 820. The entire test portfolio exhibited short loading times and a smooth gameplay. It was fun to control games using the precise touchscreen besides the accurately working position and accelerometer, and left us craving for demanding tracks which will hopefully soon be available.
高通的SoC（系统级芯片）运动的Adreno225 GPU的图形。还有许多游戏在Windows Phone8店提供特别苛刻的3D游戏仍然是稀缺的。我们测试星球大战“，飞行控制，植物大战僵尸，愤怒的小鸟拍摄1UP和极品飞车：热力追踪的Lumia820。整个测试组合表现出短的加载时间和流畅的游戏。这是使用精确的触摸屏除了准确位置和加速度计来控制游戏的乐趣，并为要求苛刻的轨道，希望这将很快可以给我们留下的渴求。
Speech Quality
The Lumia 820's telephone app does its job very well. Several test calls exhibited a flawless voice and audio quality when making calls with the test device. Background noise is kept within limits and is sooner to be ascribed to the network quality than the device. The volume is sufficient even for calls in louder surroundings. The hands-free function over the mono speaker installed in the lower edge is also acceptable. However, sound reproduction is extremely tinny particularly in higher volumes. The sound quality is treble-heavy and lets mids and bass recede into the background. It also becomes obvious that the microphone could have been a bit more sensitive in louder surroundings.
The included Wh-208 headset corresponds to that of the Lumia 920 and features a mixed quality. Although it is still alright for calls, a high-quality headset or headphones should be used for playing music, games and movies.
Lumia820的电话应用程序做的工作非常出色。几个测试要求与测试设备拨打电话时，表现出一个完美的语音和音频质量。背景噪声保持在一定限度内，迟早是要归因于该设备的网络质量比。量是足够的，甚至电话，在响亮的环境。的下边缘安装在单声道扬声器的免提功能也是可接受的。然而，特别是在较高的体积极其尖细声音再现。音质高音沉重，让中频和低音退化到后台。它也成为明显的麦克风已经有点高涨的环境更加敏感。
包括WH-208耳机对应的Lumia920，并设有一个质量良莠不齐。虽然它仍然是不行了呼叫，一个高品质的，应使用耳机或耳机播放音乐，游戏和电影。
Emissions
Temperature
The smartphone is usually held in a hand during use. Consequently, a good temperature management is essential for pleasant handling. While the test device remained within an acceptable range when idling with averagely 29.7°C on the front and 28.5°C on the rear as well as a maximum of 31.2°C, the Lumia 820 regrettably blundered during load. The device acknowledged the one hour stress test with a maximum temperature of 43.4°C on the back. The touchscreen heated up to 48°C. The Lumia 920 scores worse despite the same components. HTC's Windows Phone 8X shows that there is no need for this with a maximum surface temperature of 43.4°C. However, we never managed to reproduce any scenario where holding the Lumia 820 got unpleasant because it was too hot during normal use.

智能手机通常是在使用过程中在手。因此，良好的温度管理是必不可少的处理宜人。虽然试验装置保持在一个可接受的范围之内，平均为29.7℃下空转时，在正面和28.5°C的后部，以及一个最大为31.2℃，的Lumia820在负载过程中遗憾地失蹄。该装置承认了一个小时的压力测试，最大温度为43.4℃下的背。触摸屏，加热到48℃。的Lumia920的分数差，尽管相同的部件。 HTC的Windows电话8X显示此也没有必要用的最大表面温度为43.4℃。然而，我们从来没有成功地再现任何情况下举行的Lumia820有不愉快的，因为它是太热，在正常使用过程中。
(-) The maximum temperature on the upper side is 48 °C / 118 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 43.3 °C / 110 F, compared to the average of 33.9 °C / 93 F
(+) In idle usage, the average temperature for the upper side is 29.7 °C / 85 F, compared to the device average of 32.8 °C / 91 F.
Energy Management
Power Consumption
The Lumia 820's screen and CPU use the lion's share of power. Idle mode consumes between 1.5 and 3.2 watts. The Lumia 920 consumes more with 2.1 - 3.9 watts in this state, but it also has a bigger screen. HTC's Windows Phone 8X is more energy-efficient with 2 to 2.6 watts although the configuration and screen diagonal are virtually identical. Our Voltcraft VC 940 recorded a consumption between 4.4 and 5.7 watts during load. The Lumia 820 even surpasses the bigger Lumia 920 here, which consumed a maximum of 5.4 watts. HTC's 8X ranged between 3.7 and 5.6 watts during load. In return, Apple's iPhone 5 proves to be a downright energy saving champion with a maximum consumption of 2.9 watts. The included 6.5 watt power supply unit is sized adequately.
耗电量
Lumia820的屏幕和CPU使用电源的大部分份额。空闲模式消耗1.5瓦和3.2瓦之间。的Lumia9202.1 - 3.9瓦在这种状态下消耗更多的，但它也有一个更大的屏幕。 HTC的Windows Phone8X更节能2〜2.6瓦，虽然配置和屏幕对角线尺寸几乎是相同的。我们VOLTCRAFT VC940消费录得4.4和5.7瓦之间，在负载。 Lumia820的甚至超过了更大的Lumia920，这消耗了最大5.4瓦。 HTC的8X介于3.7和5.6之间的瓦负载时。作为回报，苹果的iPhone5被证明是一个彻头彻尾的一个最大功耗为2.9瓦的节能冠军。包括6.5瓦的电源单元的大小充分。

Battery Runtime
Nokia states a maximum standby runtime of 360 hours for the Lumia 820's lithium ion battery with a capacity of 1650 mAh. We also tested the battery life in different application scenarios. The test device's maximum battery runtime using minimum brightness and enabled energy saving mode was 18.5 hours. For this, a read script is processed in the benchmark. HTC's Windows Phone 8X only achieved just below 15 hours despite a bigger 1800 mAh battery. With its even smaller, strong 1440 mAh battery, Apple's iPhone 5 endurance runner easily outperforms all contenders (approx. 22 hours). The Lumia 820's 6.1 Wh battery finished the WP Bench load test in maximum brightness after almost 2 hours, which is standard for this device category. Our practical Wi-Fi test is performed in medium brightness, so 168 cd/m² in this case and using a browser script that opens another website every 40 seconds. The Lumia 820 lasted for impressive 12 hours, which is a whole 3 hours more than HTC's 8X. Apple's iPhone 5 and the Lumia 920 also accomplish considerably longer runtimes here. We ascertained a call time of roughly 6 hours via the UMTS network. The light, 54 gram PSU fully recharges the battery in a bit over 3 hours.
电池运行时间
诺基亚的Lumia820的锂离子电池容量为1650毫安，待机360小时的运行时间规定最大。我们还测试了电池的寿命，在不同应用场景。测试设备的最大电池运行时使用最低亮度和启用节能模式下为18.5小时。对于这一点，读出的脚本是在基准处理。 HTC的Windows Phone8X略低于15小时，尽管只实现一个更大的1800毫安时的电池。凭借其更小的，强大的1440毫安时的电池，苹果的iPhone5耐力亚军轻易地胜过所有竞争者（约22小时）。 Lumia820的6.1瓦电池完成WP工作台负载测试在最大亮度经过近2个小时，这是此设备类的标准。我们实际的Wi-Fi测试是在中等亮度，所以168在这种情况下，使用浏览器脚本，打开另一个网站，每40秒的CD/平方米。的Lumia820延续了令人印象深刻的12小时，这是HTC的8X整个3小时以上。苹果iPhone5的Lumia920也相当长的运行时间在这里完成。我们确定了通话时间约6小时，通过UMTS网络。光，54克电源完全充电的电池，有点超过3小时。
Verdict
Nokia offers a decent midrange smartphone with its Lumia 820. The good build and rigid casing are compelling. The device scores with its high-contrast, relatively bright 4.3 inch touchscreen featuring a resolution of 480 x 800 pixels and a very good color reproduction. The brightness could however be a bit higher for outdoor use. Other plus points are the intuitive, smooth operation and numerous Nokia apps. The components provide an appealing application performance alongside acceptable power consumption. The resulting battery runtimes reaped in a "Good" from us. The lush configuration, featuring a decent primary camera, NFC and LTE for all networks as well as dual-band Wi-Fi also belongs to the assets. The low gross storage capacity of 5 GB is countered by a micro SD card reader. One drawback of the Lumia 820 is that it does not belong to of the lightest of its kind. Moreover, the high temperature development in load was noticed adversely. We also found the headset's unbalanced sound disappointing.
Ultimately, the Lumia 820 receives a purchase recommendation from us. Buyers who can live with the listed shortcomings will find a decent smartphone for EUR 400 in the Lumia 820. It could have good chances on the market when Microsoft's Windows Phone 8 store has grown.
诺基亚提供了一个体面其Lumia820的中端智能手机。好身材和刚性外壳引人注目。该器件分数其高对比度，相对明亮的4.3英寸的触摸屏，分辨率为480×800像素和一个很好的色彩再现。然而，亮度可以高一点，适合户外使用。其他的加点是直观的，运行平稳，众多的诺基亚应用程序。组件提供了一个有吸引力的应用程序旁边可接受的功耗表现。收获了一个“好”从我们所产生的电池运行时间。郁郁葱葱的配置，设有一个体面的主摄像头，NFC和LTE，以及所有网络双频无线网络也属于资产。反驳低总存储容量为5 GB的微型SD卡读卡器。 Lumia820的一个缺点是，它不属于最轻的一种。此外，高温负荷发展注意到不利。我们还发现，耳机的声音不平衡失望。
最终，Lumia820的接收一个购买推荐我们。买家谁可以忍受上市的缺点，将找到一个体面的400欧元的Lumia820智能手机。微软的Windows Phone8店已经成长时，它可以在市场上有很好的机会。
