案例
尽管IdeaPad Flex 7i机箱与IdeaPad Flex 5i相同，但有一个简单的方法可以从视觉上将这两种型号区分开来。IdeaPad Flex 7i放弃了沿左侧边缘的专有AC充电端口，因为它只使用USB-C充电。不幸的是，联想没有增加第二个USB-C端口来进行补偿。这是少数没有两个或更多USB-C端口的USB-C笔记本电脑之一，如果你有USB-C外围设备，这可能是令人沮丧的。
与Flex 5i一样，仍然支持Thunderbolt 4，以支持各种坞站。

配件和保修
除了交流电适配器和文件之外，零售盒中没有任何额外的东西。有源手写笔是单独出售的。
如果在美国购买，制造商提供为期一年的有限保修。
显示
显示屏可以说是区分IdeaPad Flex 7i和Flex 5i的最大区别因素。Flex 5i采用了1200p的IPS触摸屏，sRGB覆盖率仅为60%，而我们的Flex 7i采用了更高分辨率的2240 x 1400p面板，sRGB覆盖率接近100%。升级的幅度很大，用户仅凭肉眼就能分辨出其中的差别。
然而，也有一些缺点，包括与1200p Flex 5i面板相比，最大亮度、对比度和响应时间都略有下降。值得庆幸的是，它们还不足以真正减损更深的色彩和更高的像素密度。同时，更快的90赫兹刷新率选项目前只保留给成本较高的瑜伽系列。

* ... smaller is better
显示屏开箱后的校准效果很差，这对于像IdeaPad Flex这样的中端系列来说是很常见的。色温太暖，灰度随之受到影响，正如我们下面的Calman屏幕截图所示。然而，一旦正确校准，平均灰度和色彩deltaE值将分别下降到0.7和0.6。建议应用我们上面的校准过的ICM配置文件，或者自己校准显示器，以更好地利用其全部sRGB色彩。
Display Response Times
ℹ
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.| ↔ Response Time Black to White | ||
|---|---|---|
| 33.6 ms ... rise ↗ and fall ↘ combined | ↗ 18.8 ms rise |  |

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 89 % of all devices are better.

Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||
业绩
测试条件
在运行以下任何性能基准之前，我们通过Windows将我们的设备设置为性能模式，并通过联想Vantage设置为极限性能模式。建议用户熟悉Vantage，因为它是关键更新、系统设置、保修选项等的控制中心，如下面的截图所示。
联想Vantage上有三种电源模式。极限性能、智能冷却和节省电池，分别与Windows性能、平衡和省电模式相关。该系统默认设置为智能冷却。
处理器
CPU的性能非常好，相对于其他具有相同性能的笔记本电脑来说，我们期望它能达到这样的水平。 酷睿i7-1255U处理器的其他笔记本电脑相比，它的性能非常出色。尽管如此，它的速度只比 酷睿i5-1235U比IdeaPad Flex 5i快5-10％左右。你将不得不考虑使用酷睿P系列或 Ryzen 7 6800U以获得更显著的整体性能提升。例如，较大的15.6英寸Flex系列包括Core P选项。
Turbo Boost的可持续性是有限的。当循环运行CineBench R5 xT时，我们最初的1377分会在第二次循环时下降到1165分，代表性能下降约15%。在运行Prime95时也可以观察到性能的下降，详见下面的压力测试部分。

系统噪音
尽管性能不同，但风扇的噪音特性和行为与我们在Flex 5i上测量的基本相同。当运行游戏等高要求的负载时，风扇的最高噪音为38 dB(A)，而浏览或流媒体等低要求的负载则安静得多，为28 dB(A)或更低。请注意，智能冷却模式下的风扇噪音上限为36.3分贝（A），略低于极限性能模式下的38分贝（A）。该系统仍然比大多数其他14英寸可折叠电脑更安静，包括Inspiron 14 7420 2合1.

压力测试
当在Extreme Performance模式下运行Prime95时，CPU时钟频率和温度将提升到3.4 GHz和49 W，持续约20秒或直到核心温度达到92 C。此后，时钟频率和温度将下降，直到分别稳定在2.5 GHz和71 C左右，并且最终的板卡功耗为25 W。因此，在运行要求较高的应用程序时，你会想启用极限性能模式。
运行更高的负载，如游戏，将看到一个稳定的GPU时钟速率和温度1137兆赫和65℃，分别比1100兆赫和58℃在 HP Dragonfly Folio G3由相同的GPU驱动。
如果用电池供电运行，CPU的性能会下降。在电池上进行3DMark 11测试，物理和图形得分分别为12601和6302分，而在主电源上则为16437和6220分。

能源管理
消耗功率
总体功耗略高于我们在类似条件下对IdeaPad Flex 5i的记录，这可能是由于Flex 7i的原生分辨率显示器略高，而且其整体性能水平更快。
在运行Prime95时，我们能够从小型（约11 x 4.8 x 3厘米）65瓦的USB-C交流适配器记录到71瓦的最大功耗。由于系统的Turbo Boost潜力有限，这一速率只持续了20秒左右。当长时间运行高要求的负载时，消耗量反而会在35W到45W之间。

电池寿命
电池容量从Flex 5i的53Wh提高到Flex 7i的59Wh。然而，我们的Flex 7i设备的运行时间缩短了约两个小时。
从空电到满电大约需要90分钟。第一个充电周期可能非常慢，但随后的周期应该会快很多。在联想Vantage上，快速充电是默认启用的。

Pros
+ 全sRGB覆盖是标准配置
+ 良好的CPU和GPU性能
+ Wi-Fi 6E是标准配置
+ 支持Thunderbolt 4
+ 相对安静
Cons
- 只有一个USB-C接口用于充电和数据
- 固态硬盘的性能节流
- 显示屏有明显的重影
- 显示器需要校准
- 扬声器很弱
结论 - 对于这个价格来说，显示和性能都很棒
与IdeaPad Flex 7相比，IdeaPad Flex 7向前迈出了几步，也向后退了几步。 笔记本Flex 5.它有一个稍大的电池，但电池寿命似乎没有任何延长。它现在只支持USB-C充电，但只有一个USB-C端口用于充电和配件。最后，触摸屏的分辨率更高，颜色更深，但响应时间和亮度分别稍慢和更暗。
IdeaPad Flex 7i配备了一个优秀的1400p触摸屏，比其他大多数在1000美元以下价格范围内的14英寸转换机要好。除此以外，与竞争对手相比，该机型没有其他突出之处。
幸运的是，这些缺点还不足以克服该机型的核心优势。更具体地说，该显示器比Inspiron 14 7420的显示器更清晰、更鲜艳。 Inspiron 14 7420 2-in-1 而性能比搭载酷睿i5的IdeaPad Flex 5更快，而不需要更大声或更热。这两个优势将是在类似价格下选择联想机型而不是其他机型的主要原因。对于未来的机型，联想绝对应该整合第二个USB-C端口，以提高多功能性。
价格和可用性
2022年的IdeaPad Flex 7i是，现在在亚马逊发货为1100美元，在我们的确切配置。否则目前在Lenovo.com没有库存。.
