How we created an advanced cooling system in the #GalaxyS7 and #GalaxyS7edge

Not all of the Galaxy S7 and S7 edge’s features are obvious. Some improvements are intrinsic to the experience but go largely unnoticed by the average consumer. The smartphone’s cooling system is one such feature. Although not as eye-catching as curved glass, thermal control is directly responsible for a device’s performance and lifespan and vitally important to the user experience. We sat down with Principle Engineer Kyungha Koo, Senior Engineer Haejin Lee, Senior Engineer Joenggyu Jo, and Senior Engineer Sanghyun Yi to discuss the challenges and breakthroughs of developing the Samsung S7 and S7 edge’s cooling system.

Q. How is the cooling system of the Galaxy S7 and S7 edge different from conventional technology for smartphone thermal radiation?

Koo: Using smartphones applications such as games and videos requires the hardware to perform at high levels and therefore generate heat. When the temperature reaches a certain point, the application processor (AP) decreases clock rates to prevent excessive heat build-up. Therefore, many studies have been conducted to figure out how to effectively radiate heat from smartphone devices during use.

The most important part of the Galaxy S7 and S7 edge’s cooling system is the thermal spreader (Heat Pipe). We use a spreader that is only 0.4mm in diameter, making it the thinnest in the market today. Unlike the conventional thermal spread sheet technology, the thermal spreader uses changes in the phases of water to radiate heat. It has a porous structure on the inside where water absorbs heat, turns it into steam and moves it through pipes. After losing heat, the steam liquefies and turns back into water in the structure. This continuous cycle dispels heat. Generally, its thermal conductivity is more than 50 times higher than that of copper. The entire process happens inside a small space that is only 0.2mm wide.

Q. Why did you embed the cooling system?

Jo: The latest Galaxy S7 and S7 edge have a high performance AP and enabling extended use of these features concerned us. To disperse more heat effectively, we embedded the thermal spreader. This ensures high performance and also lessens surface heat at the same time.

Q. Did you have to adjust the development process due to the cooling system?

Yi: Throughout the smartphone development process, the controlling heat remains an important focus for us. In order to introduce a new feature to smartphones, the hardware and software have always been subject to changes and adjustment during development.

The Galaxy S7 and S7 edge were designed to optimize the cooling system from the start. This is a new approach. The related R&D divisions and departments shared a common goal to effectively maximize the use of the cooling system. After much research, we were able to launch a smartphone that minimizes excessive heat from the device.

Q. Does this cooling system continue to work while the smartphone is in use?

Lee: Yes, the cooling system continues to work while the smartphone is in use. An easier way to think of it is that the cooling system acts like a network of roads. When there is no traffic, you can use regular roads, but if there is traffic congestion, highways are useful to spread out the traffic volume. The thermal spreader is that highway. It spreads the heat evenly to prevent the smartphone from overheating.

Q. How effective is the cooling system to controlling heat?

Jo: The cooling system is in fact the hardware thermal spread solution. However, due to the spatial limits of smartphones, the cooling system’s cooling capacity alone is not enough to cool the device. We need to calculate the amount of electric current and optimize the heat control algorithm to minimize occurring heat. In other words, the new thermal spreader hardware controls the heat more effectively but the software heat-control algorithm must be made compatible to ensure best performance.

The Galaxy S7 and S7 edge are the first to implement the latest cooling system, so we thoroughly evaluated whether the system would affect other circuits or the performance of other functions while cooling down the device. Additionally, since the cooling system required new technical components, we worked closely with related teams to ensure the device remained cost effective to our customers.

Q. How did you get the ideas for the cooling system and its compositions?

Koo: There were three major ways. First, we improved conventional thermal conductive materials. We also applied the thermal solution to not only smartphones, but wearable devices, cameras, tablets, PCs and other products. So another way to improve the system is to execute cross-platform reference on thermal solutions applied to different devices and optimize its performance. In that process, we sometimes make an entirely new thermal solution for a certain product. Last but not least, testing out new materials is an indispensable part, so through diverse channels like our internal laboratory and external academic circles, we collected information and conducted reviews for potential use in our products.

Q. What was the most difficult aspect of developing the cooling system?

Lee: There were many technical challenges during the development phase, including the challenge of actually installing the cooling system without altering the overall slim design of the smartphone. We couldn’t find an existing thermal spread that was as thin as we wanted, so we set out to develop our own. Since this was our first time implementing a thermal spreader, we had to go through a trial process to figure out the best standards to measure the system’s effectiveness. However, in the end, we were able to successfully develop a thermal spreader and received positive feedback from consumers.

Yi: Another challenge was cutting a groove on the bracket to install the cooling system. The larger the cooling system, the larger the groove required to house it – and a large groove can compromise the strength of the device. However, we eventually came up with a perfect place that was big enough to house the cooling system yet maintained the strength of the device. As a result, the thermal spreader in the Galaxy S7 is 30% bigger than the original design.

How we optimized battery and charging on the #GalaxyS7 and #GalaxyS7edge to be ready whenever you are
 
The Galaxy S7 and S7 edge have been designed to be ready whenever you are. Greater battery capacity, faster charging, and optimized hardware and software resourcing help the Galaxy S7 and S7 edge deliver the type of usability and convenience users have come to expect without compromising Samsung’s design heritage.
 
We sat down with Youngho Seo and Seonyoung Park of the Mechanical R&D, and SeungChul Choi and Chulwoo Park of the Advanced Component Technology department at Samsung to discuss what went into these optimizations and the challenges they faced when working to balance the three most important elements of the battery usage triangle – efficient and larger battery size, extended running time, and faster and safer charging.
 
Q. What are some of the challenges of developing smartphone batteries?
 
Youngho Seo: Customers often feel that their battery on their smartphone is not enough — they want it to last longer. Although it should be possible to increase battery capacity to meet the user’s expectations, there are technical difficulties at play that make it difficult to do so. Finding ways to overcome these obstacles is the toughest challenge in battery development.
 
Seonyoung Park: Another challenge in battery development is the long trial period. Smartphone batteries have to be tested for many years in order to prove they deliver the same performance, even after hundreds of recharges. This obviously takes a long time.
 
Q. What did you focus on the most in working to improve the battery of the Galaxy S7 and S7 edge?
 
Youngho Seo: A key focus was to improve the battery’s energy density, which is the amount of energy stored in a specific size of a physical space. We were determined to design a battery with increased capacity—but without adding any bulk—in order to preserve the Galaxy S7’s compact design. As a result, higher energy density was applied to the Galaxy S7 and S7 edge, equipping both phones with battery capacities of 3,000mAh and 3,600mAh respectively.
 
Q. What other steps were taken to increase the battery running time of the Galaxy S7 and S7 edge?
 
Seungchul Choi: In order to extend battery life, it is crucial to have both a larger power storage capacity and minimal electricity consumption rate-per-hour. Power consumption will increase unless battery usage is optimized by adding components like the smartphone chipset design to its application. To extend the Galaxy S7’s battery life, we worked across the many departments that led the development of the Galaxy S7 at every stage — from planning to verification. When too much energy was used while developing new features, we conducted thorough reviews and worked together on solutions to provide the same function while consuming less energy.
 
In addition, various options were introduced to the new phone to reduce energy consumption, such as the App power saving feature, which is a function that lets users set a specific time during which the application is inactive and can save power within the Smart Manager.
 
Q. Have you made any improvements to the battery to reduce the charging time?
 
Chulwoo Park: Samsung has provided a fast-charging feature since 2014 when we launched the Galaxy Note4. When the Galaxy S6 launched last year, we added algorithms to enhance stability during fast charging. In the Galaxy S7 and S7 edge, the usability has been improved even further with the addition of a new algorithm for longer battery life.
 
The fast charging technology needs to not only save time – but do it safely. We do this by ensuring that there is no excess electricity inflow through the product other than the amount required for charging. This is possible through bilateral communication, which monitors the power charging levels between the device and charger. In addition, safety features inside the charger protect the smartphone and battery against possible issues such as dirt, or water interference.
 
Specifically, the Galaxy S7 and S7 edge have a seven-step safety feature that is applied to the charger and battery to enhance consumer protection.
 
Q. Since the Galaxy S7 and S7 edge are water and dust resistant, would it be safe to charge them when they’re wet?
 
Chulwoo Park: For safety purposes, the Galaxy S7 and S7 edge have an ID pin in the USB port that will detect that the device is connected to the charger. If a foreign substance like water is sensed by the ID pin, the charger will not work. It is recommended that phones are kept free from moisture and any other foreign substance before charging.

Getting to Know the Design of the #GalaxyS7 and #GalaxyS7edge
 
The Galaxy S7 and Galaxy S7 edge are testaments to Samsung’s unrelenting pursuit of creating human-centric devices in both form and user experience. Our design approach for the Galaxy S7 and S7 edge was to create a device that not only resonates to your touch, but one that also captures your attention the first time you lay eyes on it.  
 
To strike this balance we aimed to simplify our design by adding complex technology to its production. The new Galaxy S7 edge front glass is designed with 3D thermoforming technology, a process that has allowed us to give the device a seamless depth unseen in a smartphone until now. All you need is to pick up the device and feel the difference in your hands.
 
We lowered the profile of our side buttons and rear camera, further accentuating the fluid design of the Galaxy S7 and S7 edge. In addition to a streamlined design, we achieved IP68 certification (water and dust resistance) on both devices to allow your phone to go anywhere that you do. All without sacrificing the design with rubber flaps.
 
The Galaxy S7 and S7 edge come in four colors: Black Onyx, Gold Platinum, White Pearl, and Silver Titanium. Black Onyx, one of the newly developed colors, applies a unique pattern that fractures light into a unique ebony hue found only on the S7; Gold Platinum, is reminiscent of smoky quartz; Silver Titanium mixes white and silver for a stern yet vivid feel. Whichever you choose, each color affects the glass material in a distinct and unique way.

The road to water and dust resistance on the #GalaxyS7 and #GalaxyS7edge

The Galaxy S7 and Galaxy S7 edge are designed to be water and dust resistant. Samsung rose to the challenge of addressing one of the largest pain points for consumers by developing an innovative technology that didn’t interfere with the beauty of the phone’s design.

We sat down with Suk Chul Park and Jung Min Choi, senior engineers in the Mechanical R&D team, to ask them about the challenges and rewards of making the Galaxy S7 dust and water resistant.

Q. What differentiates a water and dust resistant phone from other devices on the market?

Choi: Normally, when a mobile phone is exposed to water, the liquid leaks into the body, eroding its hardware and causing electrical shorts. These phones are designed with special materials or tapes that safeguard them when they are exposed to small amounts of water. However, these measures cannot protect them against larger quantities of water.

In contrast, water and dust resistant phones are equipped with a more advanced technology that prevents moisture from reaching their inner workings. This technology allows people to use the phone safely, even in very wet environments.

Q. What is most notable about the water and dust resistant features of the Galaxy S7 and S7 edge?

Park: Most other water and dust resistant phones come with bulky detachable covers or a clunky design, but the Galaxy S7 and S7 edge offer excellent protection without sacrificing the aesthetics of the phone.

To ensure exceptional water and dust resistance, we conducted rigorous experiments to find the right materials to seal the device’s USB port without using protective caps. We were looking to do this without compromising the device’s compact look and feel.

It is definitely not easy to apply the water and dust resistance to a mass-produced flagship smartphone, but to design a metal-body phone without a cap was a huge challenge as well.

Q. What technology did you use to accomplish this?

Choi: To start, we looked at making potentially vulnerable parts more water and dust resistant. Non-corrodible materials like Nickel and Platinum were selected for frequently used parts such as the USB port or earphone jack, not to harm the functionality.

Another point was to use special elastic material during assembly for sealing to block the moisture. When assembling individual parts like USB port, earphone jack or SIM card tray, there has to be a slight hiatus. Special silicon-type material is used to close that gap to prevent water from getting into the phone.

Q. What unique development challenges did you have to tackle when making the Galaxy S7 and S7 edge?

Choi: Finding the right liquid-sealing material was probably the biggest challenge. We needed a material that was fairly solid to repel water, but also flexible enough to function as a sealant.

We also needed it to be easily removable to allow people to make repairs to the device, and also to ensure it would not be affected by temperature and humidity changes. Finding the right materials involved a lot of trial and error.

Park: One of those efforts was to apply water and dust resistant feature within the limited bezel space in order to maintain its size.

In particular, the Galaxy S7 edge has an extremely narrow bezel and curved display which made it impossible to apply water protective tape around the edge. To maintain and highlight the curved display of the Galaxy S7 edge, a different approach was needed. The material and location of the water protective tape were changed and liquid sealing material was used for the curvy area and to connect the taped part. The curved display is also made up with water resistant material.

Q. What did you need to do to enable functionality without negatively affecting the devices’ aesthetic appeal?

Park: Through our research, we were able to develop ultra-thin water protective tape that provides high levels of water and dust resistance. We also developed a special sealant that can protect against water in both flat and curvy parts of the devices.

Special connection technology was also used to seal the space between the device’s metal frame and plastic parts for the antenna placement, replacing the plastic resin method used in previous devices. We also used non-corrodible materials and an erosion-free coating to protect the exposed parts of the device from humidity.

Q. Is it possible to use the Galaxy S7 and S7 edge underwater? Can users take them to the waterpark or the beach?

Choi: It won’t present any problems if you use these devices under fresh water for a short time, but it is recommended that you do so according to the product specifications. In fact, the Galaxy S7 and S7 edge are certified with an IP68 rating, which is the highest rating available for water and dust resistance of electronic appliance. However, ratings do not guarantee a device’s performance beyond the specified depth of water, or in liquids other than water.

We would recommend against using the phones for longer periods of time under high-pressure water taps, or in the ocean or other saltwater environments.

Revolutionizing low-light photography on the #GalaxyS7 and #GalaxyS7edge

Smartphone cameras continue to improve and the Galaxy S7 and Galaxy S7 edge are ahead of the curve. The Galaxy S7 uses a Dual Pixel image sensor for the first time in a smartphone camera to tackle low light photography like a professional-grade camera. The all-new sensor allows for fast and accurate shooting without sacrificing image quality, regardless of lighting conditions. 

The Power of Dual Pixel Sensor

Dual Pixel technology has traditionally been utilized in high-end DSLR cameras to send light to two image sensors separately to adjust the focus, just like the human eye, for improved autofocus performance.

Using the same technology, the Galaxy S7 and S7 edge come equipped with 1.4 μm pixels (a 56 percent increase in size compared to the Galaxy S6) and a large F1.7 aperture (which allows for 25 percent more brightness). Combined, these features enable for 95 percent more light, making it the ideal phone for capturing the moment no matter the lighting. Furthermore, the S7 employs autofocusing at considerably faster speeds, allowing for faster shooting.
 
Brighter, Better Selfies

In 2002, Samsung developed the first phone built with a front-facing camera. Since then it has continued its efforts to improve the selfie experience- increasing pixel resolution, supporting wide-angle photography, and introducing a brighter lens to the front camera.

The front camera on the Galaxy S7 and S7 edge features an F1.7 lens to deliver bright, clear selfies, even in low light. It also supports a Selfie Flash feature, which enables the user to use the Super AMOLED display of the phone as a camera flash when taking selfies in a low light environment.
 
The camera flash on the Galaxy S7 and S7 edge has a greater but softer light-emitting surface than that of an LED flash. The result is a much softer surface lighting effect without the harshness of a front LED flash. Plus, once the device’s camera recognizes your face, you can adjust the intensity and direction of the light in order to make your selfies even more expressive.
