A battery is a combination of electrochemical cells composed of three fundamental components: cathode, anode, and electrolyte. A chemical reaction occurs in a cell when the cathode and anode of the battery are connected to an external device, allowing electrons to flow via the circuit. A smartwatch is a touchscreen digital watch with several other functions besides timekeeping, as most manufacturers use lithium-ion (Li-Ion) batteries. Li-ion rechargeable batteries guarantee a long battery life as they enable many charge-discharge cycles without a memory effect.

Increasing Awareness Regarding Fitness to Boost Market Proliferation

The market is expected to see an increase in smartwatch adoption due to the rising propensity for fitness tracking and health monitoring capabilities. Companies have developed smartwatches with innovative health monitoring features such as SpO2 and blood oxygen sensors, electrocardiograms, a stress monitor, and calorie counter. Numerous companies, such as Noise, Fossil Group, Inc., Fitbit, and SAMSUNG, are bringing smartwatches with health checking feature. For example, in September 2021, Apple, Inc. launched the new Apple Series 7 smartwatch model, which has multiple health monitoring features such as natural sleep tracking, electrocardiogram (ECG) sensor, blood oxygen saturation, heart health monitoring, and improved fall detection.

The growing popularity of fitness among youth and the increasing acceptance of fitness tracking devices should help increase the consumption of such products. The International Health Racquet and Sportsclub Association stated in January 2020 that 33% of the millennial generation and 14% of Generation Z were classified as members of health clubs in the U.S. in 2018. The world is likely to experience increased demand for the product due to increasing awareness regarding smart devices. Unitednations.org noted in May 2018 that the global urban population had increased to 4.2 billion in 2018 from 751 million in 1950.

DRIVING FACTORS

Growing Demand for Portable Electronic Devices to Propel Market Growth

The income level of the world's population is rising, allowing them to spend more on housing and equip their homes with emerging technological products. Most electronic devices used in personal activities and households, such as tablets, smartphones, watches, laptops, and remote controls, are rechargeable and boast high battery life.

Demand for wireless electronics is increasing with the rapid rise in internet connectivity and digitization. Physical activity monitoring and measurement, environmental sensing, real-time data collection, and communication are some of the main applications which are essential features of smartwatch devices and are expected to meet customers' fundamental needs. In addition, increased fitness awareness has led to the integration of Artificial Intelligence (AI).       

Furthermore, the growing demand for wearable electronic devices such as smartwatches has fueled the demand for smartwatch battery. Advances in battery technology and increasing consumer disposable income have fueled the growth of the global market. Benefits such as lightweight nature, long battery life, and fast charging capability are the factors that are expected to support the smartwatch battery market growth

Advanced Features of Smartwatches to Elevate Market Proliferation

Day-to-day fitness activities, such as steps taken, calories burned, distance covered, and others, can be easily monitored and tracked by smartwatches. Smartwatches can be easily connected to smartphones via wireless connectivity or the Bluetooth function. This also helps the athlete or any client to plan their daily tasks. In addition, smartwatches also have good verbal commands, play music, access notifications, call and mobile payments, etc. This multitasking feature also increases demand for smartwatch. This factor is consequently surging the demand for smartwatch battery.

In addition, the ongoing technological advances made by key players are also stimulating the demand for smartwatches as they are technical products that require constant research and development for various functions. In this context, Fossil launched its sports smartwatch in 2019. It is powered by the QUALCOMM snapdragon wear 3100 processor and runs Google's redesigned wear OS. This product is ideal for all health and activity enthusiasts.

RESTRAINING FACTORS

Availability of Smartwatch Alternatives to Hinder the Market Growth of Smartwatch Battery 

The alternative to smartwatches is regular watches/traditional watches, which have a strong existence in the marketplace. A conventional watch is an analog dial with hour and minute hands. Regular or traditional watches can offer the advantage that smartwatch does not provide, i.e., longevity. In addition, traditional watches have excellent designs and look more aesthetic compared to smartwatches, which is also expected to hinder the adoption of smartwatches. Furthermore, low-income consumers prefer regular watches which will act as a challenge for businesses in this domain.

Moreover, technical glitches in smartwatches are challenging to fix. The battery life of traditional watches is way better than smartwatches. More importantly, some smartwatches come with faulty sensors. This might happen due to a lack of calibration or a low-end sensor. This results in failure of tracking fitness related data. Further, minor bugs that accumulate over time can mislead the user's interpretation. Therefore, digital watches are often aimed at a smaller group of buyers. This factor is consequently hindering market expansion of smartwatch battery.
