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 Siemens ST55 is 120 x 160 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 rear camera of the Siemens ST55 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.

Digital zoom in this case offers zooming up to 4x. 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.

The battery size of Siemens ST55 is 750 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 standby time for this phone is 140 hours and tells us how long the phone lasts on a single charge when you're not actively using it. The phone Siemens ST55 will last one charge with constant phone calls 270 minutes.
