DISPLAY Sharp AQUOS Crystal 306SH
Display Type LCD display
Screen Size (Display Size) 5" Better than 56 % of phones rated.
Screen Resolution (Display Resolution) 1280 x 720 pixels Better than 63 % of phones rated.
Display Format HD
Pixel Density 294 ppi Worse than 74 % of phones rated.
Colour Depth 16.7 million colours Better than 98 % of phones rated.

The screen size reaches 5" 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. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.

Display Resolution of Sharp AQUOS Crystal 306SH is 1280 x 720 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 294 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.

PROCESSOR Sharp AQUOS Crystal 306SH
Processor Type (CPU) Qualcomm Snapdragon 400
Clock Speed 1.2 GHz Worse than 67 % of phones rated.
Processor Core Qty Quad-core Worse than 57 % of phones rated.
Graphics System (GPU) Qualcomm ADRENO 305

Sharp AQUOS Crystal 306SH is equipped with Qualcomm Snapdragon 400. The number of processor cores is 4. 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. Sharp AQUOS Crystal 306SH reaches the frequency of 1.2 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 305.

MEMORY Sharp AQUOS Crystal 306SH
RAM 1.5 GB Worse than 59 % of phones rated.
Internal Memory Size (Storage Capacity) 8 GB Worse than 72 % of phones rated.
Supported Flash Memory Cards (Expandable Memory) microSDHC, microSDXC - up to 128 GB

The phone´s internal memory capacity is 8 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. This memory capacity is ideal for those who have a few basic apps and a few dozen photos on their phone. If you don't expect to use your phone to play games or need to store high-resolution photos, this size should be sufficient. There is almost no probability you're likely to see this low capacity on new smartphones. The standard memory today is around 64 and 128 GB. The best phones have internal memory of 256 GB or more. 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 Sharp AQUOS Crystal 306SH is 1.5 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 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 8 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. Some users will also appreciate facial recognition feature, which allows camera to recognise the face of person in frame and automatically focus on it.

Front camera
The front camera of phone Sharp AQUOS Crystal 306SH has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 1.2 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo.

BATTERY AND CHARGING Sharp AQUOS Crystal 306SH
Battery Capacity (Battery Size) 2040 mAh Worse than 52 % of phones rated.
Talk Time 780 minutes Better than 63 % of phones rated.
Battery Technology Lithium Ion

The battery size of Sharp AQUOS Crystal 306SH is 2040 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. 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. Sharp AQUOS Crystal 306SH is provided with a talk time about 780 minutes.
