The screen size reaches 6.67" 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 ASUS Zenfone 8 Flip is 2400 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.

The refresh rate is 90 Hz. This value indicates how many times per second display shows new information. Previously, 60 Hz was considered the standard, but today the average frequency for mid-range phones is more like 90 Hz. Modern phones now reach frequencies of around 120 Hz and above. Higher frequencies mean a better user experience when browsing the internet and especially when playing games.

PROCESSOR ASUS Zenfone 8 Flip
Processor Type (CPU) Qualcomm Snapdragon 888 5G
Processor Number SM8350
Clock Speed 2.84 GHz Better than 97 % of phones rated.
Processor Core Qty 8-core Better than 99 % of phones rated.
Graphics System (GPU) Qualcomm ADRENO 660

ASUS Zenfone 8 Flip is equipped with Qualcomm Snapdragon 888 5G. 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. ASUS Zenfone 8 Flip reaches the frequency of 2.84 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 660.

MEMORY ASUS Zenfone 8 Flip
RAM LPDDR5 SDRAM - 8 GB Better than 96 % of phones rated.
Internal Memory Size (Storage Capacity) 256 GB Better than 98 % of phones rated.
Memory Interface UFS 3.1
Supported Flash Memory Cards (Expandable Memory) microSDHC, microSD, microSDXC - up to 2 TB

The phone´s internal memory capacity is 256 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. Best phones like this one have 256 GB to 1 TB of memory, which is already enough for even the most demanding geeks who use the phone to create videos, take high-resolution photos and play more demanding games. The downside is that with most phones, you'll have to pay extra for that kind of storage capacity. 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 ASUS Zenfone 8 Flip is LPDDR5 SDRAM - 8 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.

FRONT CAMERA

The rear camera of the ASUS Zenfone 8 Flip 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 main lens is designed as Wide-angle lens. The resolution of the main lens is 64 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 typically around 0.8-1.8 μm in better mobile phones. The higher the value, the better the quality of the resulting photo should be. In the case of main lens, the pixel size reaches 0.8 μm.

The size of the phone's sensor is also among the parameters that affect quality of the photo. In case of ASUS Zenfone 8 Flip, it is 1/1.7". Focus mainly on the value after the slash, where the higher it is, the better photo quality will be. 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.

Second camera
The second lens of rear camera is designed as Ultra wide-angle lens. The resolution reaches size of 12 Megapixel. Pixel size in this case is 1.4 μm. Furthermore, the second lens is equipped with aperture of F/2.2.

Third camera
Lens number three represents the Telephoto lens. The resolution of third lens is then 8 Megapixel. The pixel size that significantly affects quality of photo is 1.4 μm.

BATTERY AND CHARGING ASUS Zenfone 8 Flip
Battery Capacity (Battery Size) 5000 mAh Better than 99 % of phones rated.
Fast Charging Technology Qualcomm Quick Charge 4.0, Power Delivery 3.0 Better than 86 % of phones rated.
Recharge Time (Charging Time) 1.7 hours Better than 75 % of phones rated.
Battery Technology Lithium polymer

The battery size of ASUS Zenfone 8 Flip is 5000 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. The fast charging function will also please many people. Owing to fast charging, phone charges up to several times faster, which you will appreciate, for example, on the go.
