Samsung’s trifold smartphone features reverse wireless charging.

Samsung has filed a patent for reverse wireless charging technology for a three-part foldable smartphone with a front display. Samsung has later developed many foldable smartphone models, the most current of which are the Galaxy Z Fold 3 and Galaxy Z Flip 3. In the future, Samsung is anticipated to release further foldable phone variants. Consider a Samsung smartphone that can be rolled up. LetsGoDigital has reported on a Galaxy Z Fold model with a vertical hinge.

In addition, the South Korean manufacturer seems to be actively developing a tri-fold smartphone. Earlier this year, it was speculated that Samsung’s first dual-folding phone was slated for late 2021. We now know that plan won’t be realized. Despite this, the development of this Galaxy foldable phone continues steadily. For example, in August of this year, Samsung Display presented a preview of a “Galaxy Z Flex” which can be folded into 3 parts. Meanwhile, Samsung Electronics is developing new technologies and possibilities to take the user experience of a tri-fold phone to the next level.

With a smartphone with reverse wireless charging, you can use the phone’s battery to charge other devices, such as Galaxy Buds, a smartwatch, or another phone. The patent documentation shows that Samsung also wants to implement this technology in its trifold smartphone. Since the phone consists of three parts of the screen, the necessary adjustments will be made. Wireless power transmission is located in both the second and third parts of the housing. In this way, the user can place the device to be charged between the foldable phone, after which the charging begins the process, as shown in the patent images above. Normally, you should place the device on the back of the phone. By placing the device to be charged between the two parts of the screen, better power transfer can occur, according to the documentation. Speed ​​gains can also be achieved because two wireless charging coils are integrated instead of one.

For example, if you charge your smartwatch, health information such as heart rate, stress level, sleep index, and blood pressure will also appear on the front display.
