The screen size reaches 5.6" 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 Microsoft Surface Duo 256 GB is 1800 x 1350 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 401 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.

Internal Memory Size (Storage Capacity) | 256 GB | Better than 98 % of phones rated. |
Memory Interface | UFS 3.0 |
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.
RAM memory of the Microsoft Surface Duo 256 GB is 6 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 battery size of Microsoft Surface Duo 256 GB is 3577 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 240 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. Microsoft Surface Duo 256 GB is provided with a talk time about 1620 minutes.
