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 8746 (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.
       Response Time Black to White
48 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 26 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 99 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 26 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

联想的C2不仅是一个电池巨擘:它还提供了一个稳固的机身,能拍摄相当清晰照片的主摄像头与绚丽明亮的屏幕。此外,扬声器不会太差,发热有限,并且电池续航良好。电池也是可拆卸的,所以联想C2可以说是拥有持续作战能力的“猛兽”。所有这些,在某些情况下,可以在网上以不到100欧元(约106美元)的价格获得。 

这个智能手机是联想一个真正值得庆贺的成就,虽然存在缺陷,但是它们大多是细节上的:使用免提功能时有可察觉的背景噪声,主摄像头录视频能力远远不如拍照片的能力。在这个价格范围内,SoC比起其他智能手机的功能,有点不够那么强大,而且一些游戏只能在较低的图像质量设置下运行。但总的来说,联想C2可以在速度上跟上与其价格相似的智能手机。只不过存储访问真的很慢...

C2,联想为市场带来了的拥有优秀性价比的智能手机:在摄像,显示和电池续航方面,它远超同类竞争对手。性能的局限使它无法与其他价格更昂贵的设备竞争。

非常好的性价比,使联想C2值得推荐给任何正在寻找续航时间长的入门级智能手机的用户。联想C2目前是这个价格范围内最好的设备之一,前提是你愿意牺牲一点系统性能。
