Chinese company Xiaomi has decided to be ahead of everyone in innovation and has applied for a patent for a smartphone with a solar battery mounted on the back panel.

It is noted that the use of a solar battery will practically not increase the thickness of the smartphone. According to the concept of the device, the phone will also have two cameras, frameless display and a fingerprint scanner inside the screen.

Also, there is no place on the smartphone where you can see the front camera, suggesting that it may be paired with a fingerprint sensor.
