We've conducted a detailed review of the Z4, looking into its battery, how easy it is to use the camera, and whether the CPU performance is high or low. Not only that, but we've also evaluated how portable and easy to hold it is, as well as how nice the display is.

Z4's battery performance

The battery performance of the Z4 is 2050mAh, which is a normal capacity. Compared to other smartphones, the Z4 has a normal amount of battery life. There is nothing to be worried about with everyday use. However, if you are using the internet or playing a game for a long time, you might feel a bit frustrated with the battery life.

The Z4 has a width of 2.7inches (69.2mm), a length of 5.2inches (132.9mm), and a thickness of 0.4inches (10.3mm). It might be possible to operate it with one hand, but depending on the person it might feel big. In addition, the weight of the Z4 is about 5.0oz (143g). Even if you are operating it with one hand it feels almost weightless. However, depending on the person, you may feel tired after using it for a while.

Assessing the overall ease of carrying the Z4 in terms of size and weight, it will not be a problem for everyday use.

Z4's screen

Z4 has a 4.5 inch display. It is large enough and you will rarely encounter issues due to the screen size. However, note that it is not very suited for writing long text.

In terms of screen quality, Z4's screen appears pixelated when displaying images and videos. You will notice some overall roughness as well.

Z4's CPU specs

With the 1.5GHz×4(Quad core) for processing power, the Z4 has relatively low performance, and for gaming, watching movies and the like it may feel slightly lacking in power. However, for usage such as net browsing, phone calls, Twitter and Instagram you probably won't feel much stress.

The Z4 has only 1GB of RAM, quite a small amount. Cases of insufficient RAM occur regularly so even when using light apps there will be instability in operation and jerkiness.

Evaluating the overall speed of operation of the Z4, it is a low-end smartphone and even in everyday use feels jumpy and jerky. There will probably be a lot of cases when you feel that it is lacking in performance.

Z4's storage size

The data storage capacity of the Z4 is 8GB, and if its main use is for texting and social media then there is no problem, but if you plan to use it for things like photography, filming, and games, you should go with one that is a step up.

The Z4 is compatible with SD cards, so it is possible to increase the capacity easily. Therefore, you probably do not need to be concerned with the storage capacity.

Z4's general rating
