Samsung Electronics filed a patent with WIPO (World Intellectual Property Office) and the USPTO (United States Patent and Trademark Office) for a ‘method for controlling a plurality of batteries and electronic device.’ The patent was published on 3 January 2019.

The patent describes a Samsung folding smartphone with two batteries, one in each housing. The design is similar to the Galaxy Fold, as Samsung has shown at the Developers Conference. In other words, the Samsung smartphone unfolds into a tablet-format device. By using a double battery, larger battery capacity can be realized. To prevent both batteries from flowing simultaneously, and thus, in fact, draining too quickly, Samsung has developed the following technology.

Both batteries are provided with a charging circuit. Both charging circuits are connected to each other by means of a current control circuit. In addition, a switch is applied. In this way, voltage differences between battery 1 and battery 2 can be effectively controlled. The battery capacity and impedance may differ from each other. The batteries of the Samsung Galaxy foldable smartphone can be charged both wired and wireless.

The processor detects which battery has the highest battery level, so as to use the battery with the most energy. This works the same for charging, the battery with the least remaining power being charged first. If the temperature of one of the batteries is too high, the other battery is automatically switched on.

Remarkably enough, this patent speaks again about the application of a holographic display. Last month LetsGoDigital reported on a Samsung 3D hologram smartphone, where it is possible to project holographic images in the air. A similar function is also described in this patent.

The patent description does not give any information about the battery capacity. According to the aforementioned research report from CGS-CIMB Research, the foldable Samsung Galaxy smartphone will be provided with a total battery capacity of 5,000 to 6,000 mAh.

The research firm also reported that the foldable Samsung smartphone will have a dual camera with both 12-megapixel resolution. In addition, the phone is supposedly equipped with an 8-megapixel selfie camera.

Furthermore, the Samsung Galaxy foldable smartphone will be equipped with a modified Android OS in combination with the new Samsung One UI. The beta program of this new user interface is currently extensively tested. Probably the first foldable smartphone from Samsung is powered by the Exynos 9820 / Snapdragon 855 processor with 8GB RAM memory and 128GB storage memory. It is possible that other memory variants are also released.

Concurrent LG has in the past also applied for a patent for a foldable LG smartphone with a double battery. An additional display also requires a larger battery capacity. With the advent of the foldable smartphone, a double battery seems to be inevitable.
