Lenovo Tab M7平板电脑评测:装了安卓Go的Kindle杀手

Mike Wobker, 👁 Daniel Schmidt, Andrea Grüblinger (translated by Zewei Shen), 02/25/2020
Android Tablet Touchscreen

非常廉价。 凭借第二代Tab M7,联想将价格非常低廉的平板电脑推向市场,尽管其硬件性能较差,但仍能获得很好的表现。 多亏了Android Go,没有不必要的软件,而且仅售79欧元(约合88美元),即可提供您期望从此类设备获得的几乎所有功能。

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: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18215 (minimum: 5 - maximum: 2500000) 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.
       Response Time Black to White
34.8 ms ... rise ↗ and fall ↘ combined↗ 17.6 ms rise
↘ 17.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
50.4 ms ... rise ↗ and fall ↘ combined↗ 29.2 ms rise
↘ 21.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 83 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.3 ms).

Lenovo Tab M7没有强大的功能。 基准性能测试结果不是很好,而且Wi-Fi和存储空间差强人意。 说到续航时间,具有如此低功耗的设备可能会从其3500mAh电池中受益匪浅。

Lenovo Tab M7是正在寻找具有原生Android体验的简单平板电脑的人的选择。

归根结底,我们非常喜欢Tab M7。 构建质量很稳定,与Amazon Fire 7不同,它没有厚厚的,令人讨厌的屏幕边框。基础版的Android Go仅售79欧元(约合88美元),是亚马逊Fire OS的很好替代品,后者具有许多专有的亚马逊应用程序。 那些正在寻找便宜小巧的平板电脑(主要用于上网和偶尔观看视频的人)的Lenovo Tab M7代表着价格相对合理的相对较高质量的设备。
