Alcatel 1S (2021) Specifications, Tests and Review

The Alcatel 1S (2021) has a height of 165.64 mm, a width of 75.59 mm and a thickness of 8.8 mm. The weight of the phone is 190 g.

The screen size reaches 6.52" inches. With a large display, phone offers a great experience for watching videos, playing games and reading. The best phones today are 6.5'' or more. They have the advantage of a large display area that allows you to see more content than with conventional display sizes. 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.

Display Resolution of Alcatel 1S (2021) is 1600 x 720 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px.

Alcatel 1S (2021) is equipped with MediaTek. The number of processor cores is 8. It is a number of cores that plays an important role in evaluating the performance of phone as it is responsible for computing operations. Smartphones already commonly have a core count of around 4 to 8. Multi-core processors can perform better and reduce the processing time of a request to a minimum, which is reflected in the responsiveness of the phone, e.g. in the speed of opening applications. The processor frequency indicates how many instructions phone can process in 1 second. The higher the frequency, the better the performance. Standard processor frequency range today is between 1.8 GHz and 2.8 GHz. Alcatel 1S (2021) reaches the frequency of 1.8 GHz.

The processor also includes the graphics accelerator IMG GE8320.

The phone´s internal memory capacity is 32 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. This memory capacity is ideal for those who have a few basic apps and a few dozen photos on their phone. If you don't expect to use your phone to play games or need to store high-resolution photos, this size should be sufficient. There is almost no probability you're likely to see this low capacity on new smartphones. The standard memory today is around 64 and 128 GB. The best phones have internal memory of 256 GB or more. Luckily, most smartphone manufacturers nowadays offer models with different memory sizes to suit every user.

An additional option to increase the storage capacity of this model is to insert a memory card.

RAM memory of the Alcatel 1S (2021) is 3 GB. Most powerful phones currently have an operating memory of 12 GB or more, which is especially useful for demanding users such as gaming enthusiasts. Normally, phones nowadays have 6 to 8 GB of RAM, which means that the phone can easily handle normal operation and more demanding applications. Operating memory of less than 4 GB is found in lower-end phones or older models, and they are suitable for low-end users who don't use demanding applications and have the phone more for basic use.

The rear camera of the Alcatel 1S (2021) is equipped with 3 lenses, with each lens having a different role in taking pictures. Most common lens you'll see on smartphones is a wide-angle lens, telephoto lens or macro lens. A wide-angle lens is mainly used to capture landscapes and other spatially larger compositions where a wide field of view is needed. A telephoto lens is designed for photographing subjects at a distance and often has an optical zoom. A macro lens is ideal for close-ups and small objects. The resolution of the main lens is 13 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. Pixel size is 1.12 μm. Average value is typically around 0.8 μm to 1.8 μm on better mobile phones, and again, the higher the number, the higher the photo quality.

The size of the camera's sensor also influences the final quality of the photos. Alcatel 1S (2021)´s main lens is designed with a sensor size of 1/3.06". The higher the value after the slash, the higher the resulting photo quality. The aperture of main lens reaches F/2.0 value. The best phones have a lens with an aperture of up to F/1.5, where more light can pass through sensor and photos will be of a high quality even in low light conditions. However, lenses with apertures around F/1.8 to F/2.2 are the most common. The lower the number after the slash, the better the photo quality. Some users will also appreciate facial recognition feature, which allows camera to recognise the face of person in frame and automatically focus on it.

Second camera
The field of view of second lens reaches 87.3 degree(s). The resolution reaches size of 2 Megapixel. Pixel size in this case is 1.12 μm. Furthermore, the second lens is equipped with aperture of F/2.4.

Third camera
The field of view reaches 84 degree(s). The resolution of third lens is then 2 Megapixel. The pixel size that significantly affects quality of photo is 1.65 μm. Last but not least, third lens is equipped with a lens aperture of F/2.4.

Front camera
The front camera of phone Alcatel 1S (2021) has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 5 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo. The pixel size itself is 1.12 μm. The main lens is also equipped with aperture of F/2.2. The field of view of front camera is 76 degree(s).

A nice bonus here is the facial recognition function.

The battery size of Alcatel 1S (2021) is 4000 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 512 hours and it expresses the maximum time your phone can last on a single charge when you are not actively using it. Talk time, or we can say battery life when making calls, then indicates amount of time your phone will last from a full charge if you are constantly on a call. Alcatel 1S (2021) is provided with a talk time about 1920 minutes.

Alcatel 1S (2021) supports 4G. 5G connectivity, which is slowly replacing standard 4G connectivity, is still more the preserve of the latest phones. The operating system in this case is Android 11.

Basic connectivity standards also include Bluetooth 5.0, making it easy to communicate wirelessly with other devices such as headphones, tablets, speakers and smartwatches.
