联想 Tab K12 的评价

乍一看,联想 Tab K12 和联想 Idea Tab Plus 相似得令人困惑。然而,仔细观察就会发现它们在功能、供货范围和其他细节上的不同:Tab K12 只提供一年保修,这对商务设备来说很正常。但对于欧盟的个人用户,经销商保修期仍为 24 个月。

Tab K12 还附带一个充电器。软件没有一些预装的臃肿软件,而且针对公司的集中管理进行了更好的优化。在中欧,你主要得到的版本与 5G,我们批评没有可用的想法 Tab 加。另一方面,你必须在交付范围内没有手写笔,但你也得到 12 GB 的 RAM 作为回报。

就其本身而言,联想 Tab K12 是一款令人信服的 12 英寸平板电脑,铝制外壳相对较轻,GPS 定位精确。充电速度相当快,电池续航时间也令人信服。此外,它还配备了无 PWM 显示屏和出色的扬声器。

不过,蹩脚的 WLAN 功能和只能达到及格水平的性能以及没有指纹传感器都令人讨厌。

Pros

+ 可使用笔输入
+ 轻质外壳
+ 精确的 GPS
+ 提供 5G 版本
+ 无 PWM 闪烁
+ 充电快,运行时间长
+ 完整的扬声器音效

Cons

- 仅限 4 年更新
- 仅支持 WiFi 5
- 无指纹传感器
- 性能一般
- 仍有臃肿软件
- 供货范围不包括手写笔

价格和供应情况

联想 Tab K12 在amazon.de有售,价格约为 420 欧元(约合 485 美元)。

不过,其他在线零售商的售价也较低,约为 350 欧元(约合 404 美元)起。

联想 Tab K12 并非完全默默无闻:联想的 Idea Tab Plus就是近亲。不过,Tab K12 的目标是通过特殊的商务功能来加分,它配备了电源装置、更大的内存,甚至可以根据要求提供 5G。不过,你也必须忍受较短的保修期。

我们将对这款商务版 Tab K12 进行仔细研究,看看是否值得投资。

外壳 - 令人印象深刻的轻质铝机箱

Tab K12 的铝制机身重 530 克(约合 1.2 磅),就其尺寸而言非常轻巧,但看起来仍然很结实,几乎无法扭动。

机壳上似乎印有高质量的天线,但由于背面还有一条宽塑料条,我们怀疑天线就藏在塑料条后面,其他部分只是装饰。

7 毫米(约 0.3 英寸)的显示屏边缘相当纤薄,但平板电脑仍然可以可靠地握持和操作。

该平板电脑具有 IP52 防护等级,可防止灰尘和溅水,因此不应浸入水中。颜色只是略带蓝灰色。

功能 - 带有大量内存的平板电脑

我们的测试设备配备 12GB 内存和 256GB 大容量存储。我们还配备了 5G 模块,但也有存储容量更小和仅 WLAN 的型号。种类繁多表明,企业客户可以很好地进行配置。

遗憾的是,USB 端口只能按照 USB 2.0 标准传输数据,不能输出图像信号。底部的三个 Pogo 引脚可以连接键盘盖。

microSD 读卡器

平板电脑最多可使用 2 TB 存储卡。在我们使用 Angelbird V60 参考卡进行的测试中,数据传输速率高于平均水平。

软件 - 少一点臃肿的软件

我们的测试设备配备了Android 16 和 2025 年 11 月起的安全更新,因此联想在提供及时更新方面似乎做得不多。在Android 17 之前应该会有新的操作系统,在 2029 年 9 月 1 日之前应该会有安全更新。对于这个价位的平板电脑来说,这其实还算可以,但欧盟实际上规定了更长的更新时间。

特殊模式允许在窗口或分屏视图中打开应用程序。如果公司有许多平板电脑在使用,还可以改进管理选项。联想还减少了预装的臃肿软件,以加快设置速度。尽管如此,有些应用程序仍然是预装的,这在专业环境中是难以理解的。

可持续性

包装不含塑料,制造商通常会在几个月后提供维修说明和备件。

没有关于二氧化碳排放量或所用材料的信息。

通信与全球导航卫星系统 - WiFi 5 速度缓慢,令人失望

在 Wi-Fi 环境中,它的速度并不快;Wi-Fi 5 已是最好的了。使用我们的参考路由器华硕 ROG Rapture AXE11000,数据传输速率达到了预期水平,而且相当稳定,但同类平板电脑有时要快得多。

路由器安装了 5G 模块。它提供的频率范围很广,因此平板电脑可以在许多国家使用移动互联网。在我们的测试中,随机测试的接收质量大多不错。

除了 GPS、GLONASS 和伽利略系统外,SBAS 系统也能提供更精确的卫星定位。

我们的自行车之旅显示,尽管在道路和小径上的定位并不完全准确,但定位效果良好。该平板电脑可用于导航,没有任何重大限制。

录制前置摄像头

主摄像头分辨率为 1300 万像素,提供自动对焦功能,而前置摄像头为 800 万像素,只能进行固定对焦。

图像质量可以接受,但真正的摄影发烧友会很快回到智能手机上。

您还可以使用主摄像头扫描文件,使用前置摄像头进行视频会议。两者都能很好地工作,但必须确保有足够的光线。

配件 - 可使用笔输入

包装中包括一个 45 瓦的充电器和一根 USB 数据线,以及一个用于打开卡槽的 SIM 卡工具。

您必须单独购买触控笔;例如,联想提供的带蓝牙功能的 Tab Pen Plus 售价约为 59 欧元(约合 68 美元)。键盘盖可从联想或第三方供应商处购买,有多种款式。

输入设备和操作 - 指纹传感器丢失

触摸屏反应迅速,屏幕的 90 Hz 帧速率意味着输入也能很快完成。

没有指纹传感器,只能使用 2D 面部识别进行生物解锁。这种方式虽然足够可靠,但安全性较差。因此,最好不要在平板电脑上保存商业机密。

我们在对 Idea Tab Plus 的评测中详细介绍了笔输入的感觉。 Idea Tab Plus.

显示屏 - 无 PWM 的 IPS 屏幕

子像素记录
子像素记录

幸运的是,Tab K12 的 IPS 屏幕不会出现 PWM 闪烁,因此也适合较为敏感的人群使用。分辨率为 2,560 x 1,600 像素,像素密度高,显示效果细腻。

在明亮的环境光线下,屏幕亮度约为 630 cd/m²。在较小的表面上,这一数值会略有增加。该平板电脑可在户外使用,但在阳光直射下很难看到屏幕上的任何内容。

色彩显示偶尔会有些不准确,整体略微偏绿。

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7962 (minimum: 5 - maximum: 343500) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

性能 - 越多越好

联发科 联发科 Dimensity 6400联发科 Dimensity 6400 的性能足以满足中端市场的需求,但与此同时,正如我们的基准比较所示,在这个价格范围内,你也可以买到性能更强的平板电脑。此外,SoC 并不总是能保证真正的流畅运行。

在图形性能方面,你不应该指望在最高设置下流畅地玩要求苛刻的游戏。上网冲浪通常会快速流畅。内存速度不是很快,但数据传输足够快。

四个扬声器产生的音效不错,音量也足够大。音量大时,声音会变得有些单薄,但略微可闻的低音通常可以弥补这一点。

没有 3.5 毫米音频接口,音频连接使用 USB 端口。此外,还可以通过蓝牙连接扬声器和耳机,蓝牙有许多重要的编解码器。
