诺基亚 Lumia 820 智能手机测评

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。

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。

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。

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。

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。
