微软 Lumia 550(Microsoft Lumia 550)是第一款搭载Windows 10 Mobile的平价智能手机，于 2015 年12 月(December 2015)发布，据传即使对于那些买不起微软 Lumia 950等高端设备的人来说，它也能带来良好的(Microsoft Lumia 950)用户体验(user experience)。Windows 10移动版(Mobile work)在低预算智能手机上是否能像在更昂贵的设备上一样顺畅运行？(Does)Microsoft Lumia 550是否比其前身Microsoft Lumia 535更好？在过去的一周里，我们每天都在使用Lumia 550，我们想在这篇详细的评论中分享我们对这款智能手机的看法：
硬件规格和包装
Microsoft Lumia 550包装在一个小纸箱中(cardboard box)，类似于所有Microsoft Lumia设备所用的纸箱。在正面，您会注意到只有两种可用颜色的设备图片：黑色和白色。
包装盒背面有一些关于手机规格的简要信息。您将了解到它提供 4G LTE 连接(LTE connectivity)、4.7 英寸高清显示屏(HD display)、5 MP 摄像头(MP camera)和高通骁龙处理器(Qualcomm Snapdragon processor)。
打开包装盒后，您会看到智能手机。
在所有纸板下面，您会找到电池、充电器和用户指南(user guide)。包装中没有捆绑的耳机或USB 数据线(USB cable)，但以这个价格，它不会让人感到意外。
硬件方面，微软 Lumia 550(Microsoft Lumia 550)搭载四核高通骁龙 210(quad core Qualcomm Snapdragon 210)处理器，运行频率为1.1GHz(GHz)。它包括 1GB 的RAM和 8GB的存储空间(storage space)，可通过microSD 卡(microSD card)扩展至高达 200 GB。
Microsoft Lumia 550配备 4.7 英寸高清 LCD 显示屏(HD LCD display)，分辨率为 1280x720 像素，像素密度为 315 ppi。该显示器还包括Glance 屏幕(Glance Screen)、增强的户外可读性、Lumia 颜色配置文件(Lumia Color profile)、RGB 条纹(RGB Stripe)、宽视角和自动亮度控制(brightness control)。触摸屏采用电容式多点触控技术。
电池是可更换的，它的容量为 2100 mAh，旨在持续长达 10 小时的网页浏览时间(web browsing time)。
该智能手机有一个 5 兆像素的后置摄像头，具有自动对焦和 LED 闪光灯(autofocus and LED flash)，能够以每秒 30 帧的速度录制 720p 的视频。前置摄像头的分辨率为 2 MP ，与(MP resolution)Microsoft Lumia 535上的 5MP 前置摄像头相比有所下降。在连接性方面，该设备配备蓝牙 4.1(Bluetooth 4.1)、USB 2.0、GPS 并支持(GPS and support)802.11 b/g/n wireless networking标准。因此，这款智能手机只能使用 2.4 GHz 频率(GHz frequency)连接到无线网络。
Lumia 550比 Lumia 535 小，但更厚，尺寸为 136.1 x 67.8 x 9.9 毫米（5.3'' x 2.6 '' x 0.38 ''），重量为 141.9 克（5 盎司）。
您可以在此处找到这款智能手机的所有硬件和软件规格(hardware and software specifications)：Microsoft Lumia 550 规格( specifications)。
设计和建造质量
Microsoft Lumia 550采用与其他(Microsoft Lumia 550)Lumia型号类似的优质材料，提供简洁、简洁的设计。它不是优质的，但在这个价格是你能得到的最好的。智能手机有一个光滑的、可更换的聚碳酸酯(polycarbonate cover)外壳，只有黑色或白色可供选择。微软(Microsoft)决定不再像诺基亚(Nokia)那样使用彩色封面，我们认为这是一个错误，因为智能手机用户总是更喜欢定制，而不是更少。在下图中，您可以看到我们测试的白色版本的外观。在背面，您会找到相机、闪光灯和扬声器。
智能手机没有一体成型结构，如果您取下盖子，您将可以使用电池、SIM 卡(SIM card)插槽和 microSD存储卡(memory card)插槽。
与任何其他Lumia 智能手机(Lumia smartphone)一样，您会在右侧找到power/lock button和音量(volume rocker)键。不幸的是， Microsoft Lumia 550没有硬件相机按钮(hardware camera button)，这本来会非常有用。此外，它还有用于Back、Windows 和 Search(Windows and Search)的软件按钮，而不是硬件按钮。在上边缘，您会找到 3.5 毫米音频插孔，在底部是USB 连接器(USB connector)。
Microsoft Lumia 550上的LCD 高清显示屏(LCD HD display)没有Lumia 535版本上的康宁大猩猩玻璃 3(Corning Gorilla Glass 3)保护(protection present)，它不是防刮玻璃，面板是普通LCD，而不是IPS LCD。亮度由环境光传感器(ambient light sensor)自动辅助，因此室外能见度相对较好。使用Lumia 颜色(Lumia Color)配置文件，您可以调整显示器的颜色类型，范围从自然到鲜艳，或色温(color temperature)。
在对比Lumia 550与Lumia 535的显示效果时，我们发现Lumia 550的(Lumia 550)像素密度(pixel density)较高，细节还原(detail reproduction)度更好，但色彩不如Lumia 535显示的鲜艳明亮，即使您设置Lumia 颜色配置文件(Lumia Color profile)上的颜色饱和度(color saturation)为“鲜艳(Vivid)”。不过，微软 Lumia 550(Microsoft Lumia 550)的黑色更深，对比度更好。在视角方面， Lumia 550(Lumia 550)和Lumia 535没有明显差异，尽管这两款智能手机都不擅长这一领域。
设计和制造质量对于该设备的价格来说是好的。你不会觉得你得到的比你付出的少，你会对它的外观和感觉感到满意，即使它使用的是通用设计。Lumia 550不是很大，手小的人也可以轻松使用，尽管有些人可能会觉得它太厚了。
Microsoft Lumia 550上的智能手机体验(smartphone experience)
Microsoft Lumia 550的智能手机体验(smartphone experience)总体上很好，我们的电话通话质量也很好。在电话交谈或电话会议中可以清楚地听到声音。也可以通过按下按钮来记录通话。录音以音频文件的形式存储在智能手机的存储空间中，您可以稍后随时播放。
尽管这款智能手机的包装不包含任何耳机，但我们还是用一些售后产品测试了音频质量。听音乐或看视频时，音频质量很好。智能手机的后置扬声器质量中等(medium quality)。对于一些声音改进，您可以使用Windows 10(Windows 10) 移动版(Mobile)中的音频设置提供的均衡器。
如果您从Windows Store玩很多游戏并拍摄大量照片，那么 8GB 的存储空间(storage space)将很快被填满。为了解决这个问题，您需要购买一张 microSD 卡来增加可用空间。为使设备正常工作，我们建议您购买优质的(quality one)（例如 microSD 10 级(class 10)）。
微软 Lumia 550(Microsoft Lumia 550)拥有 2100毫安时的电池(mAh battery)，在正常使用的情况下足够使用一整天。如果您要玩很多游戏、听音乐或使用(music or use) GPS 导航(GPS navigation)，电池的消耗会相对较快。
我们注意到微软 Lumia 550(Microsoft Lumia 550)的速度相当慢。从一帧到另一帧的转换是可见的，对命令的响应很慢。如果您习惯于快速设备，您可能会发现这个问题非常烦人。响应速度慢(speed responsiveness)的原因可能是操作系统(operating system)不完善，优化不够。最后，Windows 10 Mobile尚未最终确定。微软(Microsoft)仍在为大众市场做好准备，尽管它开始销售安装了该操作系统(operating system)的智能手机。我们希望随着系统的完善，这个问题能够得到解决。
使用这款智能手机一周并测试它的各个方面，我们发现它可靠且用户友好。Microsoft Lumia 550配备了普通硬件，结合Windows 10 移动平台(Mobile platform)，提供了不错的用户体验(user experience)，即使有时设备速度很慢。
Microsoft Lumia 550上的相机体验(camera experience)
正如我们之前提到的，智能手机有一个不错的 5 MP 主摄像头和一个 2 MP 前置(MP front)摄像头。使用主摄像头，您将能够以 720p 和 30fps 的分辨率拍摄好照片并拍摄高清视频(HD videos)。此外，后置摄像头(rear camera)具有自动对焦技术和 LED 闪光灯(technology and LED flash)。此外，您可以更改白平衡、感光度 ( ISO )、快门速度(shutter speed)和亮度。如果您不知道这些功能是什么，我们建议您将它们全部设置为Auto。2 MP 前置(MP front)摄像头不是很好，考虑到Lumia 535型号有一个 5 MP前置摄像头，我们觉得这真的很烦人(MP front)相机。总体而言，相机不会以任何方式发光，它可以完成工作并提供质量不错的照片。对于Facebook(Facebook)和其他流行的社交网络服务(networking service s.)来说已经足够好了。您可以在下面找到包含一些图片的图库，包括使用前置 2 (front 2) MP 相机拍摄(MP camera)的自拍照。
再次谈到视频录制时，相机非常好，但不要指望任何专业。凭借其 720p视频分辨率(video resolution)，录制的视频剪辑具有不错的质量。与 Lumia 535 相比，它绝对是一个改进，但它仍然模糊且缺乏细节。显然，我们不能在这个价位(price point)谈论视频稳定(video stabilization)。下面，您可以观看目标正在移动的视频示例(video sample)。
接下来，我们录制了一个演示，在该演示中我们捕获了更多静态环境。如您所见，质量比上一部电影要好，但同样没有任何亮点。
对于这款价格实惠的智能手机来说，相机体验(camera experience)非常好。您将很难在相同的价位上(price point)找到更好的东西。

Microsoft Lumia 550 review - The affordable Windows 10 Mobile smartphone
Microsoft Lumia 550 is the first affordable smartphone with Windows 10 Mobile, released іn Decembеr 2015, and it was rumored to bring a good user exрerience even to those who can't afford a premium devіce lіke the Microsoft Lumia 950. Does Windowѕ 10 Mobile work smoothly on а low-budget smartphone as it does on more expensive devices? Is Microsoft Lumia 550 better than its predeceѕsor - Microsoft Lumia 535? We'νe been us ing the Lumia 550 on a daily basis for the past wеek and we would like to share our oрinіon about this smartphone, in this detailed reνіew:
Hardware Specifications & Packaging
Microsoft Lumia 550 is packaged in a small cardboard box similar to those used for all Microsoft Lumia devices. On the front you will notice a picture of the device in the only two available colors: black and white.
On the back of the box there is some brief information regarding the phone specifications. You will learn that it offers 4G LTE connectivity, it has a 4.7" HD display, a 5 MP camera and a Qualcomm Snapdragon processor.
When you open the box, you will see the smartphone.
Beneath all the paperboards, you will find the battery, the charger and the user guide. There are no bundled headphones or a USB cable in the packing, but at this price, it can't come as a surprise.
In terms of hardware, Microsoft Lumia 550 is powered by quad core Qualcomm Snapdragon 210 processor, running at 1.1 GHz. It includes 1GB of RAM and 8GB storage space which can be expanded with a microSD card up to 200 GB.
Microsoft Lumia 550 has a 4.7'' HD LCD display with a resolution of 1280x720 pixels and a pixel density of 315 ppi. The display also includes Glance Screen, enhanced outdoor readability, Lumia Color profile, RGB Stripe, wide viewing angle and automatic brightness control. The touchscreen uses a capacitive multipoint-touch technology.
The battery is replaceable, it has a capacity of 2100 mAh and it is designed to last up to 10 hours of web browsing time.
The smartphone has a 5 megapixels rear camera, with autofocus and LED flash, capable of recording video at 720p with 30 frames per second. The front-facing camera has a 2 MP resolution, a downgrade compared to the 5MP front camera found on the Microsoft Lumia 535. In terms of connectivity, the device comes with Bluetooth 4.1, USB 2.0, GPS and support for the 802.11 b/g/n wireless networking standards. As a result, this smartphone can connect only to wireless networks using the 2.4 GHz frequency.
Lumia 550 is smaller than Lumia 535 but it's thicker, having a size of 136.1 x 67.8 x 9.9 mm (5.3'' x 2.6'' x 0.38'') and a weight of 141.9 grams (5 ounces).
You can find all the hardware and software specifications of this smartphone, here: Microsoft Lumia 550 specifications.
Design & build quality
Microsoft Lumia 550 offers a clean, simplistic design using good quality materials similar to that of other Lumia models. It's not premium quality, but at this price is the best you can get. The smartphone has a glossy, exchangeable polycarbonate cover available only black or white. Microsoft decided to quit using colorful covers like Nokia did, which is a mistake in our view, because smartphone users will always prefer more customization, not less. In the picture below, you can see what the white version that we tested looks like. On the back you will find the camera, the flash and the speaker.
The smartphone doesn't have a unibody construction and if you remove the cover you'll have access to the battery, the slot for the SIM card and the slot for the microSD memory card.
Like any other Lumia smartphone, on the right side you'll find the power/lock button and the volume rocker. Unfortunately Microsoft Lumia 550 doesn't have a hardware camera button which would have been very useful. Also, it has software buttons for Back , Windows and Search , instead of hardware ones. On the upper rim you'll find the 3.5 mm audio jack and on the bottom the USB connector.
The LCD HD display on the Microsoft Lumia 550 is without the Corning Gorilla Glass 3 protection present on the Lumia 535 version , it's not scratch resistant glass and the panel is a plain LCD instead of an IPS LCD. The brightness is assisted automatically by the ambient light sensor so the outdoors visibility is relatively good. Using Lumia Color profile you can adjust the type of colors of your display which will range from natural to vivid, or the color temperature.
When comparing the display of Lumia 550 with that of the Lumia 535, we have found that Lumia 550 has better detail reproduction dues to its higher pixel density but the colors are not as vivid and bright as those displayed by Lumia 535, even if you set the color saturation on Lumia Color profile to "Vivid". However, Microsoft Lumia 550 has a deeper black and a better contrast. In terms of viewing angles, there are no significant differences between Lumia 550 and Lumia 535, though none of these two smartphones excels in this field.
The design and the build quality are good for the price of this device. You won't feel that you are getting less than what you have paid for and you will be pleased with the way it looks and feels, even if it uses a generic design. Lumia 550 is not very large and it can be used easily by people with small hands although some may find it too thick.
The smartphone experience on the Microsoft Lumia 550
The smartphone experience with Microsoft Lumia 550 is generally good and so was the quality of our phone conversations. Voices are heard clearly in phone conversations or conference calls. Calls can also be recorded with the press of a button. The recordings are stored as audio files on your smartphone's storage, which you can play later, at any time .
Even though the packaging of this smartphone doesn't include any headphones, we tested the audio quality with some aftermarket ones. When listening to music or watching videos, the audio quality was good. The back speaker on the smartphone is of medium quality. For some sound improvements, you can use the equalizer provided by the audio settings in Windows 10 Mobile.
If you play many games from the Windows Store and you take a lot of pictures, then the 8GB of storage space will fill very quickly. In order to solve this problem you'll need to purchase a microSD card to increase the space available. For the device to work proper ly, we recommend that you buy a quality one (e.g. microSD class 10).
Microsoft Lumia 550 has a 2100 mAh battery, which is good enough for the entire day in conditions of normal use. If you'll play many games, listen to music or use GPS navigation, the battery will drain relatively fast.
What we noticed is the fact that Microsoft Lumia 550 is rather slow. The transition from one frame to another is visible and the response to commands is slow . If you are used to fast devices, you may find this issue very annoying. The low speed responsiveness might be caused by the unpolished operating system and its insufficient optimization. In the end Windows 10 Mobile is not yet finalized. Microsoft is still getting it ready for mass-market, even though it started selling smartphones with this operating system installed. We hope that, as the system is perfected, this issue will be resolved.
Using this smartphone for a week and testing every aspect of it, we found it to be reliable and user friendly. Microsoft Lumia 550 packs average hardware which, combined with the Windows 10 Mobile platform, offers a decent user experience, even if sometimes the device can be slow.
The camera experience on the Microsoft Lumia 550
As we mentioned earlier, the smartphone has a decent 5 MP main camera and a 2 MP front camera. With the main camera you'll be able to take good photos and capture HD videos at a resolution of 720p and 30fps. In addition, the rear camera has autofocus technology and LED flash. Also, you can change the white balance, the sensitivity (ISO), the shutter speed and the brightness. If you don't know what these features are, we recommend that you set them all to Auto. The 2 MP front camera is not excellent and we find this really annoying considering that the Lumia 535 model had a 5MP front camera. Overall the camera doesn't shine in any way, it does the job and it offers decent quality photos. Good enough for Facebook and other popular social networking service s. Below you can find a gallery with some pictures, including selfies which were taken with the front 2 MP camera.
When it comes to video recordings, again, the camera is quite good but don't expect anything professional. With its 720p video resolution, the recorded video clips have decent quality. It's definitely an improvement compared to Lumia 535 but it's still blurry and lacking in details. Obviously, we cannot talk about video stabilization at this price point. Below, you can watch a video sample in which the target is moving.
Next, we recorded a demo in which we captured more static surroundings. As you can see, the quality is better than the previous movie, but again it doesn't shine in any way.
The camera experience is good for a smartphone this affordable. You will have a hard time finding something better at the same price point.
Read the next page in this review to learn how well Windows 10 Mobile works on this smartphone and how well it fares in benchmarks.
