Apple iPhone SE (3rd generation) Specifications, Tests and Review

The Apple iPhone SE (3rd generation) has a height of 138.4 mm, a width of 67.3 mm and a thickness of 7.3 mm. The weight of the phone is 144 g. Many users will also appreciate the waterproof design.

The screen size reaches 4.7" inches. Phones with smaller displays are easier to use with one hand. The experience is less pleasant compared to phones with large displays. However, if you're buying a phone for basic use and don't want, for example, a good gaming experience or a large screen for watching movies, this size should be good enough for you. LCD displays are currently taking a back seat. This is mainly due to higher power consumption. In addition, they have the disadvantage of lower colour contrast, which can be reflected e.g. in the resulting photos. On the other hand, phones with LCD displays are in general cheaper than those with OLED technology.

Display Resolution of Apple iPhone SE (3rd generation) is 1334 x 750 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 326 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.

Apple iPhone SE (3rd generation) is equipped with Apple A15 Bionic.

The phone´s internal memory capacity is 64 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.

The rear camera of the Apple iPhone SE (3rd generation) 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 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. 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.

Digital zoom in this case offers zooming up to 5x. Of course, the higher the lens value, the more distant object can be zoomed in. Nonetheless, the disadvantage of digital zoom is that the quality and sharpness of photo deteriorates when using it. 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 phone Apple iPhone SE (3rd generation) has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 7 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.

Today, wireless charging feature is popular and appreciated by many users. You don't have to worry about your phone overheating, and it's also practical in that you don't wear out your phone's connector unnecessarily.

Apple iPhone SE (3rd generation) supports 5G. 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 iOS 15. This model also offers ability to pay by phone with Apple Pay.

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, making it easy to communicate wirelessly with other devices such as headphones, tablets, speakers and smartwatches.
