Pros
Cons
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。
