The screen size reaches 6.4" 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 OPPO Reno4 5G 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. Display´s pixel density is 409 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.

The refresh rate is 60 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 OPPO Reno4 5G
Processor Type (CPU) Qualcomm Snapdragon 765G
Clock Speed 2.4 GHz Better than 87 % of phones rated.
Processor Core Qty 8-core Better than 99 % of phones rated.
Graphics System (GPU) Qualcomm ADRENO 620

OPPO Reno4 5G is equipped with Qualcomm Snapdragon 765G. 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. OPPO Reno4 5G reaches the frequency of 2.4 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 620.

MEMORY OPPO Reno4 5G
RAM LPDDR4X SDRAM - 8 GB Better than 94 % of phones rated.
Internal Memory Size (Storage Capacity) 128 GB Better than 90 % of phones rated.
Memory Interface UFS 2.1

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 OPPO Reno4 5G is LPDDR4X 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.

Camera Features (2nd Front) 3-piece lens

The rear camera of the OPPO Reno4 5G 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 48 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 0.8 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. OPPO Reno4 5G´s main lens is designed with a sensor size of 1/2". The higher the value after the slash, the higher the resulting photo quality. The aperture of main lens reaches F/1.7 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.

Second camera
The second lens of rear camera is designed as Ultra wide-angle lens. The field of view of second lens reaches 119 degree(s). The resolution reaches size of 8 Megapixel. Furthermore, the second lens is equipped with aperture of F/2.2.

Third camera
The resolution of third lens is then 2 Megapixel. Last but not least, third lens is equipped with a lens aperture of F/2.4.

Front camera
The front camera of OPPO Reno4 5G is equipped with 2 lenses, with each lens having a different function when taking pictures. The resolution of front lens reaches 32 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 0.8 μm. The main lens is also equipped with aperture of F/2.4.

Second front camera
You won't see a second front lens on most smartphones yet. Having more than one front lens in OPPO Reno4 5G is thus rather exceptional in world of phones. The resolution of second front lens reaches 2 Megapixel. The lens aperture is designed to F/2.4.

BATTERY AND CHARGING OPPO Reno4 5G
Battery Capacity (Battery Size) 4020 mAh Better than 85 % of phones rated.
Fast Charging Technology SuperVOOC 2.0 Flash Charge Better than 86 % of phones rated.
Recharge Time (Charging Time) 36 min Better than 94 % of phones rated.
Standby Time 390 hours Better than 57 % of phones rated.
Talk Time 1560 minutes Better than 89 % of phones rated.
Run Time Details Standby: up to 390 hrs
Talk: up to 1560 min
Playback (Music): up to 37 hrs
Playback (video): up to 17.1 hrs

The battery size of OPPO Reno4 5G is 4020 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 390 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. OPPO Reno4 5G is provided with a talk time about 1560 minutes. You'll also enjoy the fast charging function, which allows for faster power flow and thus up to several times faster charging of the phone.
