诺基亚 Lumia 2520(Nokia Lumia 2520)于 2013 年底推出，但受到市场和可用性(marketing and availability)非常低迷的影响。随着时间的推移，它开始慢慢进入更多市场，我们最近开始接触它。我们非常好奇地对其进行测试，看看Windows RT 8.1的表现如何。此外，我们真的很想看看我们从诺基亚 Lumia 系列(Nokia Lumia lineup)中习惯的构建质量(build quality)是否已经转化为这款平板电脑。在对诺基亚 Lumia 2520(Nokia Lumia 2520)进行了两周的测试后，我们准备在本次评测中分享我们的结论：
诺基亚 Lumia 2520 开箱
正如您在下面的屏幕截图中看到的，诺基亚 Lumia 2520使用的包装与带有(Nokia Lumia 2520)Windows Phone的(Windows Phone)Lumia智能手机的包装非常相似。
打开包装盒后，您会立即看到平板电脑。
在您的后面会找到电源线(power cable)和电源适配器(power adapter)、SIM 门(SIM door)钥匙、平板电脑使用快速指南、保修单和一些其他宣传单。
不幸的是，诺基亚电源键盘(Nokia Power Keyboard)不包括在内，您需要单独购买。此外，不包括耳机，以防您可能会从诺基亚(Nokia)品牌的平板电脑中期待它们。
硬件规格
诺基亚Lumia 2520(Nokia Lumia 2520)配备 10.1 英寸IPS LCD 显示屏(IPS LCD display)，具有 218 ppi 像素密度和全高清分辨率(density and Full HD resolution)。它受到Gorilla Glass 2的保护，并增强了户外可见度。为其供电的处理器是四核Qualcomm Snapdragon CPU，运行速度为2.2 GHz . 配备 2GB RAM 内存(RAM memory)和 32GB 总存储空间(storage space), 可使用MicroSD 卡(MicroSD card)扩展. 平板电脑尺寸为 168 x 267 x 8.9 mm (高 x 宽 x 厚(Height x Width x Thickness)) 或 6.6 x 10.5 x 0.3 英寸。它的总重量为 615 克或 1.36 磅。电池的容量为 8120 mAh，比大多数 Windows 8.1 平板电脑的续航时间更长。
安装的操作系统(operating system)是Windows RT 8.1。你不知道那是什么？嗯，它是微软(Microsoft)为ARM处理器创建的Windows 8.1版本，就像这款平板电脑上使用的那样。这意味着您不能在Lumia 2520上使用任何桌面应用程序，除了与其捆绑的Microsoft Office 版本。(Microsoft Office version)使这款平板电脑与众不同的另一件事是后置摄像头。它具有 6.7 兆像素、4 倍数码变焦、蔡司(ZEISS)光学元件，并且能够录制全高清视频(Full HD videos)每秒 30 帧。这使它成为平板电脑上最好的相机之一。它唯一的缺点是它没有闪光灯。前置摄像头是平均 1.2兆像素的摄像头，可用于在(megapixel camera)Skype上进行快速视频聊天。与许多Windows 8.1平板电脑不同，这款具有 3G 和 4G 连接性。您可以插入SIM 卡(SIM card)并使用它连接到Internet。在无线连接方面(wireless connectivity)，Lumia 2520支持 802.11 a/b/g/n 标准，但不支持 802.11ac。此外，它不会检测 5 GHz 频率(GHz frequency)的无线网络。只有那些在 2.4 GHz 频率(GHz frequency)上的。
我们很高兴它还包括一个GPS 芯片(GPS chip)，它允许您使用与Lumia 2520捆绑的Here Maps等导航应用程序。您可以在此处找到此设备的完整硬件规格：Nokia Lumia 2520 的详细规格(Detailed specifications for the Nokia Lumia 2520)。
使用诺基亚 Lumia 2520
在设计和制造质量方面，诺基亚 Lumia 2520(Nokia Lumia 2520)非常出色。诺基亚(Nokia)将我们喜爱的关于Lumia智能手机的一切都转化为这款平板电脑。Lumia 2520 看起来不错，拿在手里的感觉很好，很容易拿着和随身携带。另外，它非常坚固。
屏幕很棒。我们喜欢ClearBlack 技术(ClearBlack technology)、出色的视角和色彩再现(color reproduction)。与许多Windows平板电脑不同，Lumia 2520可以在户外轻松使用。屏幕在阳光下的可见度比我们测试过的其他平板电脑要好得多。
初始设置后，我们立即运行Windows Update。不幸的是，将 Lumia 2520 更新到最新版本的Windows RT 8.1和最新更新需要很长时间。您应该为这项任务留出几个小时。此外，虽然Windows得到更新，但平板电脑的响应速度不如正常情况下，并且在此期间用户体验有点乏善可陈。我们不喜欢Windows Update查找、显示和安装(Windows Update)更新(updates)的速度非常慢的事实。在本次评测的前面我们提到诺基亚 Lumia 2520(Nokia Lumia 2520)拥有 32GB 的存储空间(storage space)。完成所有Windows 更新后(updates)，我们为自己的文件和应用程序留下了大约 12 GB 的存储空间。(storage space)如果您打算大量使用OneDrive、在此平板电脑上同步许多文件并在其上安装许多游戏，那么这并不是很多。如果是这种情况，您应该考虑使用MicroSD 卡扩展(MicroSD card)存储空间(storage space)。在我们完成所有Windows更新(updates)（包括一些固件更新(updates)）之后，Lumia 2520在性能方面表现出色。一切(Everything)运行顺利，应用程序启动速度快，我们可以轻松地同时执行多任务和使用多个应用程序。我们对它的表现非常满意。根本没有滞后。说到自主权， 诺基亚 Lumia 2520 续航(Nokia Lumia 2520)一天没有任何问题。从这个角度来看，它是迄今为止我们测试过的最好的Windows平板电脑。(Windows)平板电脑的音质也不错。您将享受使用MixRadio(MixRadio)听音乐和使用视频(Video)应用程序或VLC 播放器(VLC Player)观看电影的乐趣，这些应用程序现在也可用于Windows RT 8.1。诺基亚 Lumia 2520(Nokia Lumia 2520)的右侧有一个microHDMI 端口(microHDMI port)和一个micro USB 3.0端口。(micro USB 3.0)尽管它们都非常有用，但您需要购买与这些端口配合使用的单独电缆，这会增加拥有这款平板电脑的成本。
这款平板电脑具有蓝牙连接(Bluetooth connectivity)功能，您可以轻松连接到蓝牙鼠标(Bluetooth mice)、键盘和其他设备。但是，由于它使用的是Windows RT 8.1，因此您永远无法将Lumia 2520变成真正的生产力设备(productivity device)，因为您无法访问桌面应用程序。是的， Office 2013(Office 2013)的捆绑副本很有用，但您只能在Desktop上使用。此外，我们希望我们能够使用诺基亚电源键盘(Nokia Power Keyboard)，但现在很难找到这个配件。
总体而言，诺基亚 Lumia 2510 是一款出色的设备硬件，但它被一个相当弱的操作系统所破坏：Windows RT 8.1，这限制了它的实用性。(Overall, Nokia Lumia 2510 is a great device hardware wise, which is spoiled by a rather weak operating system: Windows RT 8.1, which limits its usefulness.)
基准性能
我们对诺基亚 Lumia 2520(Nokia Lumia 2520)进行了多次测试和测量，并决定将其与我们过去测试过的另外两款类似设备进行比较：东芝 Encore 2(Toshiba Encore 2)和Prestigio MultiPad Visconte 3。首先(First)，我们测量了诺基亚 Lumia 2520(Nokia Lumia 2520)启动所需的时间。由于使用的是Windows RT 8.1，我们无法安装我们通常使用的Bootracer应用程序，因此我们使用秒表并手动测量。Lumia 2520平均在 29 秒内启动，这是一个非常好的结果。
然后，我们从Windows 应用商店运行(Windows Store)3DMark 应用程序(3DMark app)来测量游戏性能。在Ice Storm Unlimited测试（目前最详细的测试）中，Nokia Lumia 2520获得了很高的分数——17051 分，比东芝 Encore 2(Toshiba Encore 2)高出 18% 。
您还可以查看在每次测试运行(test run)中每秒获得了多少帧。正如这些图表所示(graphs show)，诺基亚 Lumia 2520(Nokia Lumia 2520)在休闲游戏场景中提供的性能令人印象深刻，并且击败了许多其他Windows 8.1平板电脑。
为了评估电池使用时间(battery time)，我们使用了Peacekeeper基准，它告诉我们在浏览网页时电池的续航时间。如下图所示，诺基亚 Lumia 2520(Nokia Lumia 2520)持续了 8 小时 40 分钟，令人印象深刻。
此外，充电时间(charging time)非常快。诺基亚Lumia 2520(Nokia Lumia 2520)在 1.5 - 2 小时内充满电，具体取决于它是否完全放电，以及在充电时我们是否将其保持开启或关闭。
正如您从我们有限的测试中看到的那样，诺基亚 Lumia 2520 提供了出色的性能、超长的电池使用时间和非常快速的充电速度。(As you can see from our limited testing, the Nokia Lumia 2520 delivers stellar performance, great battery time and very quick charges.)
与诺基亚 Lumia 2520(Nokia Lumia 2520)捆绑(Are)的应用程序
诺基亚 Lumia 2520(Nokia Lumia 2520)捆绑了多个应用程序，但令人惊讶的是它没有垃圾软件。以下是您将在上面找到的内容：
-
Lumia Storyteller - 此应用程序会自动将您的所有照片和视频分组到称为故事的单独事件中。您可以浏览和修改您的故事，然后以故事视频或交互式网页的形式查看并与朋友分享。一个有趣的应用程序，也是从 Windows Phone 迁移而来的。
-
MixRadio - 尽管MixRadio已被 Microsoft 出售给 Line，但该应用程序仍然有效，您可以从世界任何地方免费流式传输音乐。这是一个很棒的应用程序，将受到许多用户的喜爱。
-
我的诺基亚(My Nokia)- 此应用程序提供有关使用 Lumia 2520 的教程、诺基亚支持的链接以及向诺基亚/微软提供有关您的设备的反馈的可能性。
-
诺基亚视频导演(Nokia Video Director)- 使用此应用程序，您可以使用自己的视频作为起点创建自定义视频。您可以合并不同的剪辑、添加音乐、文本等。
-
运营商通知(Operator Notifications)- 如果您的 Lumia 2520 中插入了 SIM 卡，您可以使用此应用程序接收移动运营商的通知。不幸的是，它不适用于所有移动运营商，因此此应用程序不会对所有用户有用。
-
Microsoft Office 2013 - 它包括 Excel、OneNote、Outlook、PowerPoint 和 Word。
我们非常喜欢与诺基亚 Lumia 2520 捆绑的应用程序。它们不会降低此设备的性能，并且为用户提供了额外的价值。我们希望更多的 Windows 设备供应商能够效仿这一策略。(We very much enjoyed the apps that are bundled with the Nokia Lumia 2520. They do not decrease the performance of this device and they offer additional value to users. We wish more vendors of Windows devices would copy this strategy.)
判决
诺基亚 Lumia 2520(Nokia Lumia 2520)提供了惊人的硬件、出色的构建质量和出色的性能。硬件方面(Hardware wise)，它是您可以使用的最好的平板电脑之一。但是，它有一个重要缺点：操作系统(operating system)及其应用程序生态系统。Windows RT 8.1没有很多应用程序，并且现有的应用程序与Android 和 iOS(Android and iOS)上的应用程序质量不同。这使得该平台变得不那么有用，因此，Lumia 2520不能用作生产力设备(productivity device)，只能用作媒体消费设备(consumption device)。话虽如此，我们还是推荐诺基亚 Lumia 2520(Nokia Lumia 2520)适用于需要平板电脑来完成简单任务的用户，例如：浏览网页、查看Facebook、Skype、YouTube、休闲游戏和其他媒体消费活动。该设备的制造质量和硬件非常出色。
Nokia Lumia 2520 Review - Amazing Hardware Spoiled By Windows RT 8.1
Nokiа Lumia 2520 waѕ launched at the end of 2013 but it has suffеred from very lackluster marketing and availability. As time passed, it started to slowly make its way into more markets and we recently got our hands on it. We were very curious to test it and see how Windows RT 8.1 fares on it. Also, we really wanted to see іf the build qυality that we got used to from the Nоkia Lumia lineup has translated into this tablet. After testing the Nokia Lumia 2520 for two weeks, we are ready to shаre our conclusions in this review:
Unboxing The Nokia Lumia 2520
As you can see in the screenshot below, the packaging used for the Nokia Lumia 2520 is very similar to that used for the Lumia smartphones with Windows Phone.
When you open the box, you will immediately see the tablet.
Behind you will find the power cable and the power adapter, the SIM door key, a quick guide to using the tablet, the warranty, and some other leaflets.
Unfortunately, the Nokia Power Keyboard is not included and you need to purchase that separately. Also, there are no headphones included, in case you might expect them from a Nokia branded tablet.
Hardware Specifications
The Nokia Lumia 2520 has a 10.1" IPS LCD display, with 218 ppi pixel density and Full HD resolution. It is protected by Gorilla Glass 2 and it has enhanced outdoor visibility. The processor powering it is a quad-core Qualcomm Snapdragon CPU running at 2.2 GHz. It comes with 2GB of RAM memory and it has 32GB of total storage space which can be extended using a MicroSD card. The size of the tablet is 168 x 267 x 8.9 mm (Height x Width x Thickness) or 6.6 x 10.5 x 0.3 inches. It weighs a total of 615 grams or 1.36 pounds. The batter has a generous capacity of 8120 mAh, making it last longer than most Windows 8.1 tablets.
The operating system installed is Windows RT 8.1. You don't know what that is? Well, it is the Windows 8.1 version that was created by Microsoft for ARM processors like the one used on this tablet. And what this means is that you can't use any desktop applications on the Lumia 2520 except the Microsoft Office version that's bundled with it. Another thing that sets this tablet apart from others is the rear camera. It has 6.7 megapixels, 4x digital zoom, ZEISS optics and it is capable of recording Full HD videos at 30 frames per second. This makes it one of the best cameras that you can find on tablets. Its only downside is that it doesn't have flash. The front-facing camera is an average 1.2 megapixel camera that works for quick video chats on Skype. Unlike many Windows 8.1 tablets, this one has 3G and 4G connectivity. You can insert a SIM card and use it to connect to the Internet. In terms of wireless connectivity, Lumia 2520 supports the 802.11 a/b/g/n standards but it doesn't support 802.11ac. Also, it doesn't detect wireless networks on the 5 GHz frequency. Only those on the 2.4 GHz frequency.
We enjoyed the fact that it also includes a GPS chip which allows you to use navigation apps like Here Maps which is bundled with the Lumia 2520. You can find the full hardware specifications of this device here: Detailed specifications for the Nokia Lumia 2520.
Using The Nokia Lumia 2520
In terms of design and build quality, the Nokia Lumia 2520 is simply excellent. Nokia took everything that we love about Lumia smartphones and translated that into this tablet. Lumia 2520 looks good, feels good to hold in your hands, it is easy to hold and carry around. Plus, it is very sturdy.
The screen is great. We love the ClearBlack technology, the great viewing angles, and the color reproduction. Unlike many Windows tablets, the Lumia 2520 can be easily used outdoors. The screen's visibility in sunlight is much better than that of other tablets that we have tested.
After the initial set up, we immediately ran Windows Update. Unfortunately, updating Lumia 2520 to the latest version of Windows RT 8.1 and the latest updates takes a very long time. You should set aside a couple of hours just for this task. Also, while Windows gets updated, the tablet is not as responsive as it is in normal conditions and the user experience is a bit lackluster during this time. We did not enjoy the fact that Windows Update was very slow to find, display and install updates. Earlier in this review we mentioned that Nokia Lumia 2520 has 32GB of storage space. After making all our Windows updates, we were left with approximately 12 GB of storage space for our own files and apps. That's not a lot if you plan to use OneDrive heavily, sync many files on this tablet and install many games on it. If that's the case for you, you should consider extending the storage space with a MicroSD card. After all our Windows updates were done, which included some firmware updates as well, the Lumia 2520 rocked in terms of performance. Everything ran smoothly, apps started fast, we could easily multi-task and use several apps at once. We were very pleased with its performance. There was simply no lag. When it comes to autonomy, Nokia Lumia 2520 doesn't have any issues in lasting you for a day. From this perspective, it is the best Windows tablet that we have tested so far. The sound quality is also good for a tablet. You will enjoy listening to music with MixRadio and watching movies using the Video app or VLC Player which is now available also for Windows RT 8.1. Nokia Lumia 2520 has a microHDMI port and a micro USB 3.0 port are on the right side. Even though they are both very useful, you need to purchase separate cables that work with these ports, which increase the cost of owning this tablet.
This tablet features Bluetooth connectivity and you can easily connect to it Bluetooth mice, keyboards, and other devices. However, since it is using Windows RT 8.1, you can never turn the Lumia 2520 into a true productivity device because you don't have access to desktop applications. Yes, the bundled copy of Office 2013 is useful but you can't use anything more than that on the Desktop. Also, we wish we had access to the Nokia Power Keyboard but this accessory is hard to find nowadays.
Overall, Nokia Lumia 2510 is a great device hardware wise, which is spoiled by a rather weak operating system: Windows RT 8.1, which limits its usefulness.
Performance In Benchmarks
We ran several tests and measurements on the Nokia Lumia 2520 and decided to compare it with two other similar devices that we have tested in the past: Toshiba Encore 2 and Prestigio MultiPad Visconte 3. First, we measured the time it takes for Nokia Lumia 2520 to start. Since it is using Windows RT 8.1, we could not install the Bootracer application that we generally use, so we used a stopwatch and measured things manually. The Lumia 2520 booted, on average in 29 seconds, which is a very good result.
Then, we ran the 3DMark app from the Windows Store to measure gaming performance. In the Ice Storm Unlimited test (the most detailed test available), Nokia Lumia 2520 obtained a great score - 17051 points, which is 18% higher than that of the Toshiba Encore 2.
You can also see how many frames per second were obtained in each test run. As these graphs show, the performance offered by Nokia Lumia 2520 in casual gaming scenarios is impressive and it beats that of many other Windows 8.1 tablets.
To evaluate the battery time we used the Peacekeeper benchmark which tells us how much the battery lasts while browsing the web. As you can see in the graph below, the Nokia Lumia 2520 lasted 8 hours and 40 minutes which is downright impressive.
Also, the charging time was really fast. The Nokia Lumia 2520 charged fully in 1.5 - 2 hours, depending on whether it was fully discharged and whether we kept it turned on or off while it was charged.
As you can see from our limited testing, the Nokia Lumia 2520 delivers stellar performance, great battery time and very quick charges.
Apps That Are Bundled With The Nokia Lumia 2520
Nokia Lumia 2520 has several apps bundled with it but it is surprisingly crapware free. Here's what you will find on it:
-
Dreamworks Dragons Adventure - A cute casual game that is based on the movie How to Train Your Dragon 2. Your children will enjoy playing it.
-
Here Maps - The Windows 8.1 version of the Here Maps app allows you to download offline maps to your tablet and use them when you are on the go.
-
Lumia Storyteller - This app automatically groups all your photos and videos into individual events called stories. You can browse and modify your stories, then view and share them with friends as story videos or interactive web pages. An interesting app that was also migrated from Windows Phone.
-
MixRadio - Even though MixRadio was sold by Microsoft to Line, the app still works and you can stream music for free, from anywhere in the world. It's a great app that will be loved by many users.
-
My Nokia - This app offers tutorials about using the Lumia 2520, links to Nokia support and the possibility to provide feedback about your device to Nokia/Microsoft.
-
Nokia Video Director - With this app you can create custom videos using your own videos as a starting point. You can merge different clips, add music, text, etc.
-
Operator Notifications - You can use this app to receive notifications for your mobile operator if you have a SIM card plugged into your Lumia 2520. Unfortunately, it doesn't work with all mobile operators so this app won't be useful to all users.
-
Microsoft Office 2013 - It includes Excel, OneNote, Outlook, PowerPoint, and Word.
We very much enjoyed the apps that are bundled with the Nokia Lumia 2520. They do not decrease the performance of this device and they offer additional value to users. We wish more vendors of Windows devices would copy this strategy.
Verdict
Nokia Lumia 2520 offers amazing hardware, great build quality and great performance. Hardware wise it is one of the best tablets that you can get your hands on. However, it has one important drawback: the operating system and its ecosystem of apps. Windows RT 8.1 doesn't have many apps and those that exist are not of the same quality like those found on Android and iOS. This makes the platform less useful and, because of it, Lumia 2520 cannot be used as a productivity device, only as a media consumption device. We this being said, we do recommend Nokia Lumia 2520 to users that want a tablet that they will use for simple tasks like: browsing the web, checking Facebook, Skype, YouTube, casual games and other media consumption activities. The build quality and the hardware of this device are simply excellent.
