[Galaxy Book Pro Series Tech Talk] ⑦ Battery

Q&A: Samsung Electronics developers on the strengths of the Galaxy Book Pro series.

Q. What changes have been made to the battery of the Galaxy Book Pro series?
The new Galaxy Pro series features a thinner body.
Of all the parts in a PC, the battery traditionally takes up the most space.
In terms of battery size, it can be compared to half a sheet of A4 paper and about the volume of half a larger orange.
To reduce the overall thickness of Galaxy Pro series devices, the battery thickness had to be reduced the most.

Q. How thin is the battery in the Galaxy Book Pro series?
For context, the battery thickness of the Galaxy Note20 is around 5.4mm(t).
The Galaxy Book Pro series 15-inch model features a battery thickness of 4.70mm(t), and the 13-inch model has a battery thickness of 4.39mm(t).

The outside structure of the battery is called the frame, which supports each cell.
The cells were made to be thinner, and every circuit inside the frame, we used thinner materials as well.

Q. How is the battery structured?
The battery is made of cells. The left side is the polymer cell, and the right side is the square cell used in phones. Four lithium polymer cells make up one pack, and this is the battery pack built into the product.

Q. Why is it difficult to make the battery thinner?
To make the battery thinner, several parts must be made smaller, but as the battery is also
a major component related to the safety of the device, there are parts that cannot be reduced.
The safety-related parts have not been changed, and we instead focused on designing the rest of the battery components with the highest possible compression rates to build a battery pack 10% thinner than the previous model.

Q. The battery has become thinner, but is the capacity still the same?
We designed the battery to maintain its capacity by leveraging a concept called the energy density of a battery which puts a lot of energy in the same space. In using this concept, we were actually able to make a product with an energy density higher than its previous version.

Q. Does a high-efficiency battery help protect the environment?
We have built a long-life battery algorithm into the product.
If you look at the carbon footprint of five years of battery conservation, it can be converted into the amount of energy equivalent to about 2,000 pine trees, and the same amount of electricity generated by a Hydroelectric Power Plant for six months. In fact, we’re proud to say that with this technology, we won the Ministry of Environment’s “CO2 Reduction Award” in 2019 and the Korean Green Product Award in 2020.

Q. Do you have any tips on prolonging battery life?
Galaxy Book Pro series devices support the Battery Life Extender + mode for long-term users.
This function optimizes battery life by avoiding stress factors on the battery during charging or
discharging. Users can enjoy optimized battery performance by first going into the Task
Manager and turning on the Battery Life Extender Plus in Samsung Settings.
