饰品我们已经习惯了这样的事实，制造商并不总是压倒我们的多样性配件。再次证实这种假设，因为所包括的配件非常稀疏。除了智能手机，我们只发现了一个模块化电源和包装盒中的快速入门指南。令人遗憾的是，谷歌甚至不包括其最畅销的耳机。然而，这是否也值得商榷，顾客可要求，鉴于当前的价格349欧元，16GB的版本。谷歌宣称的Nexus4的选项没有任何充电线充电设备。是必需的，一个可选的，感应充电智能手机放在垫子上。兼容的，第三方充电器是49.99欧元。保谷歌提供了一个12个月的保修期。买方可以利用一个额外的12个月的保修期，在保修期满后。
响应十个指头同时使用的电容触摸屏，用于输入。所有涉及准确，迅速地实施。该器件还应对各种触摸手势。默认的Android键盘预装。由于4.7英寸的大屏幕，触摸按键有足够的大小，以确保准确的打字。键盘往往占地面积小屏幕在横向模式下远远超过了50％。这不是在Nexus4的情况下。银河S3和iPhone5仍然依赖于一个物理的主页按钮。现在的Nexus系列省略了此按钮，仅在屏幕上，采用触摸控制。三个触摸式按键“返回”，“家”和“多任务”旋转与屏幕在横向模式下90°。这也意味着，约。5毫米的屏幕总是“丢失”。我们认为，竞争的概念，如三星的Galaxy系列，更有意义。主导航按钮之外的触摸屏。
分辨率为1280x768像素，4.7英寸的屏幕是不是衡量一切事物。屏幕将提供超过320ppi的实际，以确保自身在高端市场（iPhone5的326PPI）的地方。但是，抱怨在一个较高的水平。作为回报，在Nexus4的屏幕具有丰富的色彩再现令人印象深刻。275.3坎德拉/平方米的平均亮度是足够的地方在上中场。HTC8X（293.8坎德拉/平方米）小幅达到更好的利率，但它是远程从辉煌屏幕的iPhone5（486.8坎德拉/平方米）。导致93％的照明亮度几乎均匀分布在各个领域和始终如一的高水平上。差异的人的眼睛是不可见的。我们记录了一个黑色的价值0.24坎德拉/平方米使用的戈森MAVO的监视器。这将导致在一个非常高的对比度为1179:1。

谷歌的Nexus4配备了一系列有趣的硬件功能。LG和谷歌已经同意后，最新的高性能组件。该SoC（片上系统）了SnapdragonS4Pro的型号APQ8064。它是建立在一个28nm技术，并按照ARMv7指令集。四核具有一个时钟速度为1.5GHz，2MB二级高速缓存。最具前瞻性的特点之一肯定是宽敞的工作记忆。竞争机型仍然很少配备2GB。图形单元一样装备精良。了Adreno320GPU，确保足够的电力供多媒体应用。那么多理论。在低电源在微软的Windows应用商店，谷歌提供足够的合成基准的表现获得准确的概述。就整体而言，在Nexus4，取得了综合测试整个令人满意的结果。在直接与iPhone相比，Cupertino的模型提出了GLBenchmark2.5少5幅。竞争对手三星和HTC也被击败在AnTuTu的基准V2。其他厂商的旗舰达到降低约30％的得分。令人惊讶的是，华硕的PadFone2取得更好的成绩相当，在这方面及Linpack基准测试，虽然安装了相同的SoC。的Nexus4智能手机的比较，管理方式的合成基准顶尖行列。
比分看起来并不那么好，在基于浏览器的性能测试。我们的测试设备提供比三星的GalaxyS3，华硕的PadFone2或苹果的iPhone5在所有测试中得分较低。像往常一样，小的例外是谷歌V8卷。Nexus4的取得更好的成绩比HTC的8X43％。但不幸的是，没有足够的扭转相当低的分数。
*...smallerisbetter
我们的测试系列的最后部分，我们使用AndroBench3。评估闪存的写入和读取性能率。Nexus4的几乎50MB/s的连续读取256KB文件。无论是华硕的PadFone2，也不是银河S3在这里做一个更好的工作。所不同的是，即使在连续写清楚。

便携式设备正在变得更大，更高的屏幕分辨率。因此，使用智能手机作为多媒体播放器将是显而易见的事情。然而，较高的分辨率，更多的工作SoC具有播放全高清视频。很多低性能的智能手机没有达到每秒25帧以上。我们用拖车从电影中詹姆斯·邦德：SKYFALL变形金刚3：黑暗的月亮在全高清画质的测试。硬件有足够的容量，轻松呈现一切。
