Google Pixel 3 128 GB Specifications, Tests and Review

The Google Pixel 3 128 GB has a height of 145.6 mm, a width of 68.2 mm and a thickness of 7.9 mm. The weight of the phone is 148 g. Many users will also appreciate the waterproof design.

The screen size reaches 5.5" 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. Owing to OLED technology, the display offers a true representation of colours, especially black. The resulting contrast is significantly higher and colours appear more vivid. OLED technology is now part of most smartphones, while LCD displays are becoming a thing of the past in mobile phones. OLED displays also have lower power consumption compared to LCD technology.

Display Resolution of Google Pixel 3 128 GB is 2160 x 1080 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. Display´s pixel density is 443 ppi and represents another significant factor affecting image sharpness besides resolution. The higher the value, the sharper the image. Average value is currently about 350-400 ppi, which guarantees a fine and sufficiently sharp image. Finest modern phone displays reach 450 ppi and above.

Google Pixel 3 128 GB is equipped with Qualcomm Snapdragon 845. 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. Google Pixel 3 128 GB reaches the frequency of 2.5 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 630.

The phone´s internal memory capacity is 128 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. For everyday use and storing photos, songs or movies, this medium-sized internal storage is ideal. The advantage is also a lower price of phones equipped with this storage capacity. Best phones today range from 256 GB to 1 TB. That size is suitable for the most demanding users who shoot a lot of high-resolution photos or videos in 4K. Nevertheless, you'll have to pay extra for these higher capacities. Luckily, most smartphone manufacturers nowadays offer models with different memory sizes to suit every user.

RAM memory of the Google Pixel 3 128 GB is LPDDR4X SDRAM - 4 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 Google Pixel 3 128 GB 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. The resolution of the main lens is 12.2 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 1.4 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 aperture of main lens reaches F/1.8 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. An undeniable advantage is the optical image stabilisation, which makes image significantly more stable without any loss in quality. Cheaper phone models are equipped with electronic stabilisation, which has a negative effect on the resulting image quality.

Front camera
The front camera of Google Pixel 3 128 GB is equipped with 2 lenses, with each lens having a different function when taking pictures. The main front lens is designed as a Wide-angle lens. The resolution of front lens reaches 8 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo. The main lens is also equipped with aperture of F/2.2. The field of view of front camera is 107 degree(s).

Second front camera
You won't see a second front lens on most smartphones yet. Having more than one front lens in Google Pixel 3 128 GB is thus rather exceptional in world of phones. The resolution of second front lens reaches 8 Megapixel. The lens aperture is designed to F/1.8.

The battery size of Google Pixel 3 128 GB is 2915 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. Many users will also welcome the wireless charging feature. Wireless charging keeps your phone from overheating and also protects the connector from wear and tear. On the other hand, it does cause some power loss.

Google Pixel 3 128 GB 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 9.0 Pie.

Fans of modern technology will appreciate NFC function, which allows, among other things, contactless mobile phone payments, but also finds other uses in connectivity, such as unlocking the door or loading the menu in restaurant using the NFC tag. Basic connectivity standards also include Bluetooth 5.0 LE, making it easy to communicate wirelessly with other devices such as headphones, tablets, speakers and smartwatches.
