Xiaomi is working on a smartphone with a solar battery

Mobile device developers are striving to increase the battery life of gadgets in every possible way. However, engineers are limited by the size of the internal space and the mass of the device. Therefore, experiments continue with various additional ways of supplying energy for the battery of smartphones.

Xiaomi has filed a patent with the World Intellectual Property Office, which proposes to install a solar battery on the back of the smartphone. 

Constant charging of the device should theoretically provide the user with an unlimited supply of energy on a sunny day.

The patented device in front looks like a standard smartphone, though devoid of a cutout or hole for a selfie camera. There is also no hint of the now popular periscope camera that extends from the smartphone’s body. It can be assumed that the front camera will be located under the screen, they are also supposed to place a fingerprint scanner in the same place.

Most of the back panel will be occupied by a solar battery, however, space has been left for placing a double vertical main camera.

Installing a solar panel on a smartphone allows you to reduce the time for recharging, as well as provide the ability to make calls in remote areas where there may be no electricity. The only problem remains the efficiency of the panels, which so far leaves much to be desired. However, to make an emergency call, a short charging time of the smartphone will be enough.

Samsung first tried to use its own solar panel to get additional energy in mobile phones in 2009, when the consumer was offered two models equipped with such panels.

The Samsung Guru E1107 phone provided a 5-10 minute conversation after recharging in the sun for one hour. The main target audience for the Guru E1107 was consumers from countries with poorly developed energy infrastructure when people often found themselves inaccessible to power grids.

The second Samsung Blue Earth S7550 phone had a nearly similar solar panel in performance but was made of plastic made from recycled bottles. This device even had internet access.

Conducted experiments with solar panels for mobile communications and LG, which in 2010 produced the cover for the LG Pop GD510, equipped with recharge from the Sun. The efficiency of this power system was almost 2 times higher than that of Samsung phones. Three minutes of conversation provided only 11 minutes of recharging in the sun.

It is hoped that over the past 9 years, the efficiency of solar panels has increased several times and will provide a modern smartphone with enough energy.
