Changing Charging for the Better

According to Product Planner Jeongmin Moon, the development team incorporated Wireless PowerShare technology into the Galaxy S10 line to offer users the freedom to go about their day without being tied down by cables and chargers.

“We wanted to solve the inconvenience of having to carry around multiple chargers and cables when you’re out and about, or having to interrupt your day to stop at places like cafes just to charge your phone,” said Moon. “So we came up with the idea to essentially make the Galaxy S10 a wireless charger in and of itself.”

Since the release of the Galaxy S6, the first Galaxy device to offer wireless charging, more and more smartphones and wearables have begun to feature the technology as well. This, Yusu Kim noted, is another reason why Samsung prioritized incorporating wireless battery-sharing technology into the Galaxy S10 line.

“Wireless PowerShare allows you to easily share your battery’s power anytime, anywhere,” said Kim. “And as more devices begin to support wireless charging, more people will be able to experience the convenience that the technology creates.”

The technology behind wireless battery sharing and wireless charging is quite similar. A wireless charger receives DC (direct current) charge and converts it to AC (alternating current) with the battery coil before transmitting it to the receiving smartphone. The phone will then convert the AC charge back to DC and save the energy in the battery. Each Galaxy S10 device features a circuit that enables this two-way conversion, which essentially allows the phones serve as wireless chargers as well.

As mentioned above, the list of Wireless PowerShare-compatible devices includes not only smartphones, but, in an industry first, wearables1 like Samsung’s Galaxy Watch and Galaxy Buds as well. As Juhyang Lee explained, the process of enabling the technology to work with such a wide range of devices was quite a difficult task.

“The sizes of these devices’ batteries are all different, so the most difficult part of the process was finding an optimal spot for the receiving coils that would result in maximum efficiency,” Lee explained. With the smartwatch, she recalled “the receiving coil was particularly small, so it took some time to find the most efficient approach. However, after months and months of extensive research, we produced a solution that meets our strict reliability standards.”

A Smarter Approach to Battery Management

Of course, in order to share its charge with another device, your Galaxy S10’s battery must possess enough power to efficiently operate your phone. (At least 30 percent, to be precise.) To offer users more freedom to utilize this useful function, the Galaxy S10 line features AI technology that optimizes battery usage based on how you use your phone.

When building this technology, the developers focused particularly on the battery consumption of infrequently used apps. As Hongjung Son explained, “Out of all the apps that users have on their phones, only a small number are used every day. And the ones that aren’t used consume battery power in the background.”

“To limit these apps’ background activities,” he continued, “we incorporated AI technology that organizes apps into different categories, such as ‘frequently used,’ ‘occasionally used,’ and ‘rarely used.’”

The team also enabled the new smartphones’ Adaptive Power Saving mode to activate automatically² based on users’ usage patterns. Hyeonsu Lee described how it works: “If, for example, a user usually uses their phone for 30 minutes on their way to work, Adaptive Power Saving mode will automatically activate if their commute happens to get extended.”

“And because this mode is AI-powered,” he added, “the more it’s used, the more accurate it becomes.”

The efficiency of the Galaxy S10’s battery has been amplified with stronger hardware. At 7.8mm thick, it’s thinner than the Galaxy S9’s 8.5mm battery, and its capacity has been increased by 10 percent (from 3000-3500mAh to 3400-4100mAh)³.

A Powerful Vision

Each member of the product planning and development teams agrees that Samsung’s latest battery innovations will unlock unprecedented user experiences.

Moon concluded the interview by shedding some light on the company’s ultimate goals for its charging technology. “With Wireless PowerShare, we not only expect to resolve some of the inconvenient aspects of charging your devices,” said Moon. “We also expect people to communicate and engage with one another more.”

“Listening carefully to users’ feedback has enabled us to consistently improve our Galaxy smartphones,” added Kim, “and it will continue to do so. Going forward, we’ll continue to strive to develop battery technology that offers the very best in terms of users’ convenience and experience.”

¹ Using Wireless PowerShare, you can charge Samsung and Qi-certified phones, and wearables such as Galaxy S9, S9+, S8, S8+, S8 Active, S7, S7 edge, S7 Active, S6, S6 edge, S6 Active, S6 edge+, Note9, Note8, Note FE, Note5, and wearables such as Galaxy Watch Active, Gear Sport, Gear S3, Galaxy Watch (46/42mm), and Galaxy Buds. It may not work with certain accessories, covers, or other brand devices. Wireless PowerShare may also affect call reception or data services, depending on your network environment.

Actual battery life may vary depending on network environment, usage patterns and other factors.

Exploring Next Generation Battery Technology

Lithium-ion batteries were first commercialized in 1991, and widely applied to markets for mobile devices and electric vehicles. However, with standard lithium batteries requiring charging times of at least an hour to fully charge, even with quick charging technology, and considered to have reached their limit for capacity expansion, there have been numerous attempts to explore use of new innovative materials. Among the materials looked at, graphene has widely become the primary source of interest as the representative next generation material.

In theory, a battery based on the “graphene ball” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60 degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles.

In its research, SAIT sought for an approach to apply graphene, a material with high strength and conductivity to batteries, and discovered a mechanism to mass synthesize graphene into a 3D form like popcorn using affordable silica (SiO2). This “graphene ball” was utilized for both the anode protective layer and cathode materials in lithium-ion batteries. This ensured an increase of charging capacity, decrease of charging time as well as stable temperatures.

Dr. Son In-hyuk, who led the project on behalf of SAIT, said, “Our research enables mass synthesis of multifunctional composite material graphene at an affordable price. At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles is growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends.”

SAIT’s research results are covered in-depth in this month’s edition of the science journal Nature Communications in an article entitled, “Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities.” SAIT has also filed two applications for the “graphene ball” technology patent in the US and Korea.

*Graphene is a single layer of carbon atoms from graphite, and is receiving much attention in the battery and display industry due to its physical, chemical stability. Graphene is 100 times more effective than copper in conducting electricity and displays remarkable electron mobility – 140 times faster than silicon – which makes it an ideal material for fast charge.

Samsung Newsroom sat down with Sangkyu Lee, Senior Vice President of the Reliability Group, Mobile Communications Business, Samsung Electronics, to discuss more about the company’s endeavors to lead the way in product safety.

Q. What was your main priority in developing the Galaxy S8?

Sangkyu Lee: More so than ever before, we consistently worked to identify and incorporate features and functions that would provide real value for the consumer.

So often, manufacturers get caught up in specs in an attempt to outdo the competition. But rather than concentrating on numbers, we aimed to deliver practical value and safety.

For example, rather than focusing on short-term benefits – such as decreasing charging time by a few, insignificant minutes – we concentrated on maintaining the durability of the battery over the long term and specifically over hundreds of charging cycles. As a result, the Galaxy S8 will sustain its longevity better than previous models, offering more value to the consumer.

Q. What actions did you take to accomplish these goals?

Sangkyu Lee: First, we optimized the design of the Galaxy S8 itself around the battery, which we consider to be one of the most important components of a smartphone.

At the battery design layer, we adopted preventative measures to identify and address potential device safety vulnerabilities with improved battery safety standards. For instance, we created more space around the battery in order to accommodate a new bracket design to protect the battery against physical force, even when the smartphone is dropped. Likewise, we also adjusted the design to eliminate pressure on the electrode and prevent leakage of battery substrate.

At the software layer, we made improvements to our software protection algorithms that govern battery temperature, battery charging current and charging duration to reinforce safety.

Q. In addition to these design changes, what are some other ways Samsung is evaluating product safety?

Sangkyu Lee: In addition to the comprehensive inspection tests carried out by our battery manufacturer, Samsung has also incorporated its own assurance measures to improve product safety from the component level to the assembly and shipment of devices.

Included in our thorough 8-Point Battery Safety Check that we used to test the Galaxy S8 are enhanced tests – Durability Test, Visual Inspection, X-Ray Test, Disassembling Test and △OCT Test – as well as newly applied measures such as the Charge and Discharge Test, TVOC Test and Accelerated Usage Test.

Furthermore, we formed a battery advisory group of external advisers including academic and research experts to ensure Samsung maintains a clear and objective perspective on battery safety and innovation.

Q. Has the device received any third-party certification?

Sangkyu Lee: As a result of our extensive efforts, Samsung successfully completed all inspections that are required by global governments and national standards. We also carried out safety inspections through third-party research institutions.

Assessment results from UL and Exponent, among others, show that the Galaxy S8 battery was determined to comply with all applicable requirements.

Q. In addition to the measures you’ve discussed, are there any other ways Samsung is addressing product safety going forward?

Sangkyu Lee: We have also expanded Product Liability (PL) Analysis Centers throughout the world, which are equipped with state-of-the-art machinery and knowledgeable personnel.

The centers help to ensure that Samsung is prepared to respond to unexpected situations – should they arise – with speed and transparency. Of course, consumer cooperation is imperative, as we need to be able to quickly access and address the issue at hand to create a solution that will benefit all users.

This is just another example of how Samsung is working to continue making product safety our top priority.

Read on to learn more about Samsung’s 8-Point Battery Safety Check.

From as early as the planning stage of the Galaxy S8, Samsung Electronics implemented enhanced battery design standards and safer software protection algorithms. In particular, the company thoroughly checked the quality of the Galaxy S8 battery via an 8-point Battery Safety Check.

This inspection includes a number of enhanced tests, such as the Durability Test, Visual Inspection, X-Ray Test, Disassembling Test and △OCT (Delta Open Circuit Voltage) Test, as well as newly applied measures such as the Charge and Discharge Test, TVOC (Total Volatile Organic Compound) and Accelerated Usage Test.

Component Assembly

Samsung’s smartphone batteries first go through quality assurance tests conducted by the battery manufacturers. Batteries that pass these tests are then reviewed thoroughly in the component assembly stage at Samsung Electronics.

Following the Charge and Discharge Test, the battery’s durability is checked through extreme temperature stress, overcharging and puncture tests, among others. Next, the batteries are visually inspected and undergo the X-Ray Test, which examines the interior of the battery cell to identify abnormalities, such as the deformation of the outermost negative electrode.

In addition, batteries are disassembled to inspect their internal condition, including the position of the insulation tape, folding and damage of the separator, and the location of the welding spot of each tab.

The ΔOCV test, meanwhile, is performed to determine if there are any current leakages caused by foreign substances at the electrodes.

TVOC Test

Completed Device

When the Galaxy S8 is completed, the product goes through a final Charge and Discharge Test during the shipment inspection. This means that by the time the smartphone is assembled as finished product, a total of three sample Charge and Discharge Tests have been conducted.

Lastly, in the Accelerated Usage Test, smartphone functions (such as playing video or using the camera) are executed under conditions similar to those of actual consumer usage, in a condensed time frame.

Collectively, this series of checks that spans the overall battery handling process helps to ensure product quality, redefining what’s possible in product safety.

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.

The more and more that smart devices can do, the more important it is to make sure your device is functioning at its best. This means preserving the battery life, but also managing storage and RAM and keeping everything safe from security threats.

In the beginning of the year, Samsung introduced the Smart Manager, which helps users scan and optimize their smartphone, all at once. Available since the launch of the Galaxy S6 and S6 edge, the performance of Smart Manager and the devices that support it has been improving. The Galaxy S6 edge+ and Note5 come preloaded with improved battery usage, including app optimization, and security features.

Opening the Smart Manager app shows its four main components: Battery, Storage, RAM and Security. You can view and optimize your device through closing running apps and uninstalling unnecessary apps. The Security menu scans your phone for malware and other security threats. My Knox is also available to download for even more security. To boost your device’s speed and performance in a single click, use “Clean All.”

Long Live Your Battery

Smartphone users don’t always realize they can remove apps which are infrequently or never used. Sometimes apps are running in the background, consuming battery power. After selecting Battery within the Smart Manager, users can prevent wasting battery power through “App Optimization.”

For each app, users can choose between “Always Optimizing,” “Automatically Optimizing” or “Disable For.” “Always Optimizing” stops the app from using battery power. You can also select how often the apps will be optimized (every 3, 5 or 7 days). If you choose the “Automatically Optimizing” for every 3 days, the app will stop using battery power from the last usage for three days. Once the app is set for “Disable For,” you will stop receiving alerts from the app. If you don’t want to miss notifications from instant messaging apps, it’s best not to select “Disable For.”

The Battery screen also displays the percentage of remaining battery power and how long it is expected to last. By selecting Battery Usage, you can view the processes that have been running since your last full charge. Power Saving Mode and Ultra Power Saving Mode also display expected length of battery life if you need to conserve battery power. To view battery consumption of each application, select Detail.

Clean Up

To free up storage space from temporarily stored files, Smart Manager automatically scans and deletes any unnecessary data. After opening the Smart Manager app, select Storage. You can see how much of your available storage has been used. The Details button at the top of the screen shows more information about your device’s total space, available space, system memory, used space, cache data and miscellaneous files.

You can also manually delete data stored on your device. Users can check the current storage status by selecting “User Data” within the Storage menu. This displays how much space each type of files is using. If you choose the applications, you can find which apps are used more frequently. Viewing by frequency of use makes it easy to disable or uninstall unnecessary applications.

RAM

RAM is where temporary files are stored when your device runs an application. Clearing the RAM on your device will improve your device’s performance, freeing space so your device can run faster.

The RAM screen displays the percentage of used RAM, the active applications and how much RAM they are currently using. You can see how many background apps are currently using RAM space, so it helps you choose which applications to close. You can also select “End All”.

Protect Yourself

It’s possible for users to install apps or viruses unknowingly. This could lead to a breach of personal information or damage of the device. In less extreme cases, the unauthorized apps could slow down the device performance or use too much battery power.

Smart Manager automatically scans for malicious software, apps that use unusually high amounts of battery power, apps that make unusual errors and provide solutions for these issues. Users can ensure comfort and security by removing or closing unwanted apps. Samsung devices with Smart Manager provide anti-malware solutions through a partnership with Intel Security.

Take Control

With Smart Manager, Galaxy smartphone users can feel reassured that their devices are safe and secure, and running optimally. By having access to usage, storage, memory and security data, users can take matters into their own hands to know that they have a safe and comfortable space to work and play. Smart Manager is currently available for the S6, S6 edge, S6 edge+, S5, S4, Note5, Note4 and Note3, and the available devices will be expanded.

Advanced wireless charging

Samsung Galaxy S6 and Galaxy S6 edge set new industry standard in universal wireless charging with fully embedded WPC and PMA certified wireless charging technology. This means both models are compatible with most wireless charging pads currently available on the market. The Galaxy S6 and Galaxy S6 edge support both WPC (Wireless Power Consortium) and PMA (Power Matters Alliance) international wireless charging standards, allowing users to enjoy wireless charging more widely and conveniently than ever before.

Samsung began exploring wireless charging technology in the mid-2000s, and released its first smartphone with wireless charging capabilities in 2011 with the Droid Charge. The Galaxy S4, Galaxy S5, Galaxy Note 3, Galaxy Note 4 were all subsequently equipped with the same capability, enabling users who purchased a separate wireless charging back cover and a wireless charging pad to take advantage of the technology.

With the Galaxy S6 and Galaxy S6 edge, users will not have to worry about having to use separate accessories in order to charge their devices wirelessly. It simply works with any wireless pad in the market that meets WPC or PMA standards. This addition was possible because of Samsung’s efforts to minimize the thickness of wireless charging hardware components and improve efficiency.

Samsung’s engineers didn’t want to compromise beauty to power or the other, so they wanted to maintain the sleek and beauty of the Galaxy S6 and Galaxy S6 edge while having them perform at max level. This required that the coil, the key component for wireless charging, be made the smallest as possible.

To do so, Samsung abandoned all existing methods, combining two separate coils and adding two overlapping layers of magnetic shielding to prevent the magnetic field from leaking. As a result, the engineers were able to produce a component that was only 0.27mm thick, just 1/3 the thickness of the same part used in the Galaxy S5. Samsung also minimized size and cost by developing single components that could achieve the same output that had required multiple components in previous models. Samsung’s improved technology will have a real impact on the everyday lives of users no longer needing to carry bulky power cords everywhere they go.

Fast charging technology

In addition, the Galaxy S6 and Galaxy S6 edge now charge faster than ever – 1.5 times faster than the Galaxy S5. In fact, 10 minutes of charging, when plugged in with its charger, will provide users with enough power for 4 hours of usage*. This built-in supercharging technology helps users secure their power, especially when they need it most.

These improvements are the result of the advancement in Samsung’s Fast Charging technology, which debuted with the Galaxy Note4. Furthermore, the power consumption of the displays, AP, memory chips and other components of Galaxy 6 and Galaxy 6 edge have been optimized to enable up to 20 hours of use on a single charge. The smartphone automatically reduces power consumption based on each person’s use patterns.

Managing power usage

Samsung has also introduced a Smart Manager application that provides users with an overview of the applications with high battery consumption with just a single touch on the screen, allowing them to easily and conveniently manage their battery usage. With all of Samsung’s groundbreaking innovations in charging technology, the Galaxy S6 and S6 edge are truly remarkable devices that showcase Samsung’s dedication to bettering the devices that are available to consumers.
