In addition, display performance is steadily improving, and high-resolution displays are being introduced. High-performance cameras of 10 million pixels or more equipped with HD video shooting and LED flash are adopted.
As described above, the smartphone employs a large-screen display while adopting a thin-thickness design in order to enhance portability and design sensibility in addition to its high functionality, and thus has a weak point in external impact and durability.
Accordingly, the smartphone protection case includes a grip portion protruding in a semi-cylindrical shape on the case body, which is provided to protect the outer surface of the smartphone, so that it is possible to conveniently take a picture in the photography mode together with the appearance of the smartphone.
In particular, the smartphone protection case according to the present invention may further include a button portion that functions as a shutter button and a slide button portion for a zoom-in / zoom-out function in a photographing mode of a smartphone in a grip portion.
Accordingly, it is possible to conveniently use the photo shooting function while protecting the appearance of the smart phone.
However, such a smart phone has a feature of having batteries for portability. The batteries must be periodically charged. In this case, the users have to charge the battery by electrically contacting the smartphone with the charger provided when the smartphone is purchased.
Therefore, the user can not solve the problem of still having to move to the place where the power supply unit is installed in order to charge the battery.
For this reason, there is a problem that, when the user has to drive the mobile smart phone urgently at a position away from the wireless power supply, when the battery power is exhausted, an emergency occurs in which the smartphone can not be used.
