Apple Watch Illustrates the Battery Life Challenge for Wearable Technology

Editor’s note: We introduce guest blogger Mike Salas, VP Marketing, Ambiq Micro. Mike has over 23 years of semiconductor experience leading both large businesses for established technology companies as well as small company startup operations. Prior to joining Ambiq Micro, he was the Vice President and General Manager of the Microcontroller Division at Silicon Labs. Before Silicon Labs, he was the founding CEO of Layer N Networks (acquired by Thales e-Security). He has also held senior management roles at PMC-Sierra and Texas Instruments. He holds a B.S. in Electrical Engineering from the University of Texas at Austin.

The Apple Watch exemplifies the current state of wearable technology. Unveiled last month, Apple’s first product “designed to be worn” embodies much of what’s going on in the wearable industry — from the exciting, such as useful but cool and secure functionality, personalization, appealing styles, and comfortable yet sleek form factors, to the most challenging aspect… battery life. Despite all of the advances in other areas, the Apple Watch is expected to still require daily recharging when it comes to market in early 2015.

There are three basic ways to address battery life for a given device: choose a more advanced battery technology, improve charging, or increase efficiency. Let’s have a look at each approach as it relates to the Apple Watch.

Apple has not yet told us how its forthcoming watch will be powered, or how often it will need to be re-charged.

Apple has not specified how the still evolving Apple Watch will be powered, but most likely it will use the currently leading battery technology for mobile devices, Lithium (Li)-ion batteries with cobalt-oxide electrodes. Li-ion battery technology was developed in the 1970s, with commercialization of the cobalt-oxide electrode material in 1991. Though this battery technology dwarfs its rivals in performance, it is nearing its theoretical limits. Newer battery concepts are in development, such as Li-ion batteries with tin nano-crystal electrodes that are more effective at absorbing and releasing Li-ions than cobalt oxide electrodes, potentially doubling the energy capacity. However, these and other next-generation battery chemistries with even greater potential are a ways from being commercially available.

With a battery life of just a day or so, the Apple Watch needs a convenient charging routine to become a viable product. Inductive charging is the solution, with a small charging pad/connector that uses magnets to easily snap to the back of the Apple Watch. Once the watch and pad adhere to each other, energy is transferred wirelessly by magnetic induction from the transmitting coil in the charging pad to the receiving coil in the watch. No matter how simplified the process is though, a daily recharging requirement really puts a dent in the user experience.

On the efficiency front, the Apple Watch has a lot of opportunities to whittle down the power use because it is loaded with power hungry features. Besides being a very accurate watch that works with the iPhone to check its timekeeping against the definitive global time standard, the device includes a color touchscreen, phone, messaging, email, Bluetooth connectivity for headphones, secure payment capability, and an array of sensors for fitness tracking. A custom main processor is at the heart of the Apple Watch, with a design surely optimized and every operation surely scrutinized for low power consumption. Apple further elevates efficiency by employing an always-on motion co-processor to collect and keep all motion data on the device while the main processor sleeps.

After all this though, we are still talking about battery life for wearables in terms of days. Real breakthroughs will only come by taking on the battery life challenge at its most fundamental level, the IC architecture. One promising possibility is the use of subthreshold design techniques. A recent technical whitepaper by Ambiq Micro goes into the subject in depth. “Subthreshold Design – A Revolutionary Approach to Eliminating Power” can be found here.

    Since the Apple Watch must always be tethered (wirelessly) to an iPhone, a 6Whr charging source is always 2 feet away.  So it seems as long as the iPhone has a maglock with inductive power coupling, the power problem is substantially solved (i.e. maglock to phone when you go to sleep at night–no matter where you are).

    In fact, it seems that using the Watch might actually extend iPhone battery life since a much smaller screen is regularly illuminated rather than the full screen of an iPhone.

    We shall all know pretty soon….

    I believe driving force in iWatch will be how simple and user friendly they are, as i don't think it will be easy to tap your earphones in watch and attend call or listen music, this is actually very new technology packed in this small watch so battery life of device is still undecided or unpredictable.

    @samicksha some of the basic smartwatches on the market such as the Pebble can last up to a week on a single battery charge, but those devices lack touchscreens and use low-power white displays to achieve longer uptime between recharges. I believe Apple has acquired companies to meet his problem.  LuxVue, a power-efficient micro-LED, and Passif, a power-efficient chip manufacturer but those acquired technologies could take years to integrate into new products.

    @Scott Apple is experiencing multiple development issues with its iWatch, reports of the iWatch's battery problem first surfaced in early 2013, indicating that prototypes of the watch were seeing just few days of battery power before needing to be recharged. Battery life still a major issue for the Apple's device, which is said to utrilize a 100mAh battery. Apple tried several different charging technologies for the device, including solar charging (even wireless charging). But solar charging was a bust, and the company decided to ship with wireless charging, which could help to reduce the burden of frequent charges.

    “So it seems as long as the iPhone has a maglock with inductive power coupling, the power problem is substantially solved (i.e. maglock to phone when you go to sleep at night–no matter where you are).”

    @Scott:  Is this something that has already been practically implemented in the watch, or is it a feature you're suggesting? In either case, how useful and reliable do you think the magnetic charging technology is? Can it be purely relied on? Does the performance get hampered when the distance increases?

    ” Apple tried several different charging technologies for the device, including solar charging (even wireless charging). But solar charging was a bust, and the company decided to ship with wireless charging, which could help to reduce the burden of frequent charges”

    @NetCrawl: What about charging through the movement of the hand? That technology was already there in some of the old watches and it seems like there may be a possibility of reusing it. This may prove to be an important alternate charging source.

    @tzubair,

    The Apple on line video shows an inductive charging solution with a maglock.  The maglock function is similar to the maglock on the Macbook line, but the Watch also includes an inductive charging path.  The Macbook line doesn't have inductive charging.

    I think inductive charging works just fine if the coupling is managed.  With a maglock, the coupling is locked, so alignment is a non-issue.

    There probably are technical issues, but I think they may have a bigger problem with the style aspects of the product.

    Watches are a fashion statement.  How many people want a bulky Rolex?  Or a bulky Tag Heuer?  Answer:  Lots of people, if they could afford them.

    Apple, just five months ago, hired the VP of Sales for Tag Heuer.  What does someone with that title know about electronic computing technology?  I think that hire is a statement about where they see impending problems.

    I actually think the hire was smart.  Just should have been done a few years ago when Apple was thinking about style.  It appears they waited until the style was done and said, “Go sell it!” Mr. Watch Style Expert.

    The approach though is quintessential Steve Jobs.  “The customer doesn't know what they want.”  So Apple will teach them.  Maybe that works for new types of products (i.e. iPod).  Not so sure about that approach when applied to a centuries old market like watches.  So we will shortly see….

    @samicksha, no doubt this is new technology but there are already such products available in the market. It would be interesting to see how different the Apple product will be from those products and what new features Apple is going to add to attract buyers.

  13. amrutah
    December 24, 2014

    @Tzubair:

        I need to know about the maglock that Scott mentioned, but for the wireless charging which is basically a inductive charging, the primary and secondary need to have a strong coupling co-efficient.  As the distance increases the coupling can decrease and reducing the efficiency.

      The Inductive charging will take some more time to get popular, its costly, further needs to isolate from surrounding EM fields.

  14. amrutah
    December 24, 2014

    “What about charging through the movement of the hand?”


    @Tzubair: True that this kind of technology is existing, hand movement based, walking based, solar charging and so on.  These make the device bulky, they are slow charging solutions and mainly for low-power devices.  For smartphones and smart gadgets which need more power these may not be useful technologies.  These can be add-on technology (somthing hybrid) to the wired or wireless technology.

  15. amrutah
    December 24, 2014

    @yalanand:  I would like to know what Mike's thoughts are on this.  But what I understand

    1> With device being in sub-threshold the input has to be very small so that the device doesn't waver into the saturation region or cut-off region.

    2> The sub-threshold is basically a weak inversion device and most of the models need to mature.

    3> since the dynamic range is small handling the noise is a big issue.

    Steve,

      I have been hearing about the carbon nanotubes as a replacement for the batteries.  Why is this not happening? Given the power density it can hold most of these wearable device can get much smaller.

    @tzubair, Apple has been exploring wireless charging technology for years, holding a bevy of patents covering both inductive and magnetic resonance charging. Apple already won a patent for a charging dock that could switch between data synchronization, diagnostics, or charging based on the orientation of the device on the dock. 

  18. Netcrawl
    December 24, 2014

    @Scott, inductive charging technique, which operate without requiring direct conductive connections, have been developed for certain applications. Apple's inductive charging solution involves winding an audio cable for the electronic device around a charging mechanism multiple times so that one of more conductors in the audio cable form an inductive receiving coil. Then, a magnetic field is created through the charging mechanism to induce a current in the inductive receiving coil and finally, the induced current in the inductive receiving coli is used to charge a battery for the device.

    No doubt in that @Yalanand, Apple has proven track record of attracting cutomers, but matter of fact here is, Apple is unhappy with current performance and the situation is very much still in flux. Apparently, Apple is doing many different things to improve battery longevity, by the time the device launches in 'early 2015′.

    “I think inductive charging works just fine if the coupling is managed.  With a maglock, the coupling is locked, so alignment is a non-issue.”

    @Scott: I think inductive charging would definitely be needed with the watch and the maglock may not work because the alignment would change constantly. I'm not sure how reliable inductive charging would be and how much time would it take to charge compared to normal wired charging.

  22. Scott Elder

    @tzubair,

    Watch this video starting at 5:30.  http://www.apple.com/watch/films/#film-design

    The inductive solution at such a close range is probably very efficient.  Perhaps >80%.  Maybe more if the solution is resonant.  And unlike other inductive solutions, this one is perfectly aligned with lock.  Technically, the solution should work quite well.

    “lets not forget that old watches were less power hungry. These new watches have all sorts of functionality which requires more power compared to the old watches.”

    @yalanand: Yes, they were less power hungry but I think the charging output was enough to meet the demand. In this case, I think the technology can be modified a bit to increase the output to cater to the new power requirements in the watch. At least the concept can be implemented.

    “Apple has been exploring wireless charging technology for years, holding a bevy of patents covering both inductive and magnetic resonance charging”

    “These can be add-on technology (somthing hybrid) to the wired or wireless technology.”

    @amrutah: I agree. In the beginning it can serve as a hybrid technology but as time goes by, we may see it getting stronger and more reliable. This may lead it to becoming the mainstream charging technology.

    @nasimson Apple is clearly looking to be positioned in the middle of this environment by adding some layers of security, simplicity and last, eliminate as much friction and hassle as possible from ecommerce transactions. This is alwayss good for consumers, especially Apple users. The company has laid a foundation and seeing as the market appears to be on the cusp of a transition to adopt NFC (Near Field Communication) at many retailers, it will be ineteresting and exiting to see if and how Apple davances this market and Apple has the right user base and strategy to do it.

    It depends the system design has to address the terms and supply domians properly.

    My Low power design might be at 0.5V supply domain, while the input is coming from a 0.9V low power supply domain.  In such a scenario, the input might be big enough ( large signal effect) for my design to saturate to either of the rails.

    @samicksha, with battery size dictated by form-factor hardware vendors must find better ways to extend the life of their products. For Apple, I think one part of the equation is the technology behind its M7 processor in the new iPhone 5S. This secondary processor, developed by Dutch company NXP Semiconductors, allows the iPhone 5S to collect sensor data without using the power-hungry main processor, and with the iWatch rumored to contain a number of health and sensors, this processor will be even more important and big help in extending the iWatch's battery life.

    @Ranasinghe: I do agree that charging via hand movement can be a problem if you don't wear the watch for a while. However, this is a back up charging technology and not the main one. Other than this, the size issue can be resolved I guess because the newer watches are getting smaller in size each day as far as their circuit is concerned.

Apple's biggest competition is Android and truly, an android device can do twice the tasks an apple iPhone can do at half the price, so that is a big factor.

    December 31, 2014

    @chirshadblog: Yes, but in today’s fast moving world people have a lot of money and less time, hence comes things like smart watches that allow people to manage time by making them know about appointments, let them know how much calories they are burning by walking to the office etc. In my opinion though, smart watches are not needed.

  67. SunitaT
    December 31, 2014

    @yalanand: there are other options to increase the battery life as well. For the most basic thing, we are forgetting that old digital watches could run on solar power, and since solar panels and smart watches have come a long way, we can ensure that smart watches are powered by the thinnest solar power strip we have ever seen. This could solve the battery problems.

    @SunitaTO, Apple really knows how to create buzz with consumers and media, they dominate the media space with its new product launches. Apple cultivate an air of secrecy and intrigue to fuel speculation and buzz about their new products. Many tech companies go to great length to preserve confidentiality during their product development pahse, but Apple is different, its a master of the teaser marketing campaign, dragging on the suspense for as long as possible ( creating what we called excitement ). For months before the release date, the media conversation and buzz builds to deafening levels, Apple stokes the buzz by providing virtually no information about their new products.

    @chrishadblog, I agree with you, Apple products have always been designed, delightful and friendly, I say friendly because they focus on a “friendly” customer experience. They focus on removal of complexity in favor of ease of use with innovative features like SIRI or personal assistant and many more. Not only does Apple have history of innovations, they wow their customers through design and packaging, they design their products brilliantly.

    AMOLED is known to help improve battery life insmartphones, another benefit of AMOLED is that it can be extremely thin, light and rugged.

    @Netcrawl, thanks for sharing the benefits of AMOLED. Do you think in future all the products will shift to AMOLED or is there any new technology which is competing with AMOLED ?

    December 31, 2014

    I don't agree with you on it. Apple is not only famous for its design but also for its innovative features

    @chirshadblog, I am not saying that Apple is not famous for its innovative features, all I am saying is design is key strength of Apple and it has helped Apple differentiate itself from rest of the products.

  79. yalanand
    December 31, 2014

    By creating buzz for their products, Apple also create demand and market for their products.

    @Netcrawl, this may not be true always. Lets not forget what happened to iPhone 6. Since the product was not good pepole preferred buying older version iPhone rather than latest iPhone.

    I do agree that charging via hand movement can be a problem if you don't wear the watch for a while.

    @tzubair, I think we have can have multiple power sources to the watch. We can also inlucde solar panels which can continuously charge the battery. Having multiple power sources will help us avoid battery getting drained out.

    @SunitaT0: Apple has few of the best apps for iWatch (involving GPS and health) and better sync features which stands out, but as you said the cost factor is a big thing if it needs to compete with the androids.

    “I don't like the design of the Apple Watch. It does not have a classic design like the Moto 360. It looks cartoonish.”

    @SunitaT0: I think it fits well with the overall Apple design catalog. While you may find it a bit “cartoonish”, Apple's fanboys may be drooling all over it.

    Not just innovation, but disruption as well. Apple has disrupted the music industry (ipod), publishing industry (ipad), phone industry (iphone), software industry (appstore), telecom industry (facetime, AppleSIM). Now let lets see how much the iwatch disrupts the fitness tracking.

    @yalanand: exactly so. Apple products look so different and premium. Obviously the Apple logo is eye catching and is a symbol of wealth and power. Even though I have a much more powerful phone than the iPhone 5, I would still ogle at an iPhone because it just looks that pretty.

  93. SunitaT
    December 31, 2014

    The newest version of iPhone was seriously bizzare in terms of feasible design. When bendgate was created, I was shocked from thinking about what hit the sales of the iPhone would take, but after some shocking and hilarious months (shocking for Apple, duh, and hilarious for other competitors of Apple) people seem to have taken into buying this stuff again, and this time around they keep it in their hands.

    @amrutah, Apple has its own followers who dont mind paying extra for features that Apple provides. Apple commands this extra price for its brand and hence it doesnt have to worry about cost factor.

    @yalanand there's a better version of AMOLED we called Super AMOLED, Super AMOLEDs are another type of AMOLED, and its simply referring to Samsung AMOLED panels. Super AMOLED reduce the thickness of the screen by integrating the touch response layer with the display itself, it handle sunlight better than AMOLED displays and are also better on power consumption.

  106. Netcrawl
    December 31, 2014

    @dassan.an I think we can copy Apple's technique, if you want to build buzz about your products (like Apple does ) and maybe someday get your stuff to their level, we need to focus more on customer side and design. 

  107. Netcrawl
    December 31, 2014

    @dassan.an I agree with you, Apple has created a brand value that has attracted a passionate of brand community of followers who identify with the brand's innovativeness, simplicity, efficiency and coolness. These are fans who lock into the entire family of Apple products and must have the latest gadget right when it comes out- a phenomenom to behold.

    @yalanand its Super AMOLED, a better version of AMOLED display technology that integrates a capacitive touchscreens layer directly into the display instead of overlaying it on top of the display. Its a thinner design that uses less power and reflects less light and works better outdoors, it reflects one-fifth as much sunlight compared to the first generation AMOLED.

    @nasimson you're right about Apple, wearable technology (like the iWatch) could accelerate an already strong health and wellness trend, and could address health care system inefficiencies. Its probably the next era of computing, and will have a far-reaching impacts by creating a new category and disrupting or even accelerating change within industries.

    >> Yes there are many other brands but you cannot replace the quality of apple

    That is an illusion. There are many better products in the market with better ROI than Apple products. It is easier to make a phone for $566 than one for $200. Look at the value, some are better. Your analysis must include cost.

    >>  Even though I'm a die hard apple fan, im not sure how well the iWatch does because it has a very little to offer towards the market compared to its price

    I am yet to buy Apple Watch purely because I do not see the value from the product. Unless I need a new watch, there is no need. I agree that the second generation of the watch may be great. At the moment, the utility is not that compelling for me to spend money on it

  113. fasmicro

    >> I think you cannot copy apple techniques. You can copy only the design

    Absolutely, the most important element in Apple is the software. The deisgn is part of the game. If you get around the software, Apple loses its competitiveness. I think by keeping it private, Apple will keep its dominant position for a long time. That is a differentiator in the industry

  114. amrutah
    January 2, 2015

    @SachinEE: I think more than the brand factor, the apple has very intuitive OS and software that commands more cost.  Although no software is bug-free, the recent software bugs were the disrepute to Apple.

    In the hardware aspect, circuit designer might look at the ESD protection circuit using TVS diode. Specially, wearable device might be low dynamic resistance. These low capacitance diodes do not store any charge or affect high speed signal integrity and data transfer rate.

    @fasmicro: Indeed, when you check the performance and the smoothness between the 2, you can feel the difference. You do not get iPhones, which gets stuck but when you take Android based phones there are. That shows the difference between the 2 systems and its configurations.

    As supplement of power source, either solar or vibration might be used in the future iWatch with wireless charging. I guess that Lithium-ion type battery might be used for that. Apple engineer could face a challenge of putting all alternative energy source in a limited package size.

  119. ue2014

    >>>>>>>>> There are many better products in the market with better ROI than Apple products >>>>>

    I also agree with this. What keep Apple so demanding is its Brand Name & Value created for it and the software what they used (As discussed later in this discussion). 

  120. ue2014
    January 30, 2015

    Creating such a value for a Brand Name like Apple is not an easy or overnight process. After much hard work, when it is created; it's more difficult to maintain such standards set at the market. 

    Once a aperception and a value is created in consumer mind about your product, that organization should live upto it in all aspects of their product. If not that would damage their Brand Image and values.
