AT&T Z222 Specifications, Tests and Review

Design of AT&T Z222 has dimensions of 74.7 mm × 36.6 mm × 13.8 mm and weight of 92 g.

The screen size reaches 2" inches. Smaller phone displays are not necessarily a disadvantage. They are easier to use with one hand. However, displays of these sizes don't provide the same experience when watching videos or playing games, so they're better suited for less demanding users. It means, if you're a basic user and you don't expect to use your phone for activities like watching videos or playing games on regular basis, this size is perfectly adequate. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.

Operating memory significantly affects the performance of the entire phone. AT&T Z222 has an operating memory of 64 MB. Phones with less than 4 GB of RAM are better suited for undemanding users who use phone more for basic needs and some essential applications only. But if you are a heavy user, reach for at least 6 to 8 GB of RAM, which is the standard today, or 12 GB for the really demanding ones.

The rear camera of the AT&T Z222 has only one lens. Single lens is more typical for older phones or lower-end phones with lower quality cameras. The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 0.3 Megapixel. However, if you are looking for perfect photos, in addition to resolution, don't forget to focus on at other parameters such as lens aperture or pixel size.

The battery size of AT&T Z222 is 900 mAh. Nevertheless, battery capacity is not the only factor that affects the phone's battery life. For example - the size of the display, the performance of the processor, the use of data functions and, of course, the intensity of use of phone in general all have a significant impact on battery life. Standard for most smartphones today is a battery capacity of around 4500 to 5000 mAH. Phones with this battery size usually guarantee a phone life of at least 1 day. Older or cheaper smartphone models can then reach battery capacities typically around 2500 mAH and below. With this capacity, you may find that if you use your phone heavily, you may need to recharge your phone during the day.

Standby time is 195 hours. The value indicates how long your phone will last on a single charge when you are not actively using it. The battery life when making calls is, like standby time, a figure that tells us how long the phone will last on a single charge when making continuous calls. For the AT&T Z222 it is 240 minutes.

AT&T Z222 supports 3G. 4G connectivity is still common today, although the latest phones already have 5G connectivity. 3G connectivity is now more of a thing of past and can only be found on older models.

Bluetooth 2.0 EDR makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
