In 2014, Apple Pay released an update to work on iPhone 6 and Apple Watch very similar to Google Wallet, but for Apple devices only (https://www.theverge.com/2014/9/9/6127587/apple-watch-works-with-apple-pay-to-replace-your-credit-cards).

On the other hand, the battery and charging-related issues are the main pain points of iPhone 7. Referring to the market performance of iPhone 6, the battery problem has been widely complained about and discussed among consumers, so Apple introduced a battery replacement plan for iPhone 6 in a low price (from 79 dollar to 29 dollar). Nonetheless, the battery and charging performance of iPhone 7 is still the focus, and questioned about by consumers. For adapters, it can be considered jointly with ‘Lightning’ which is also negative, since a new important change for iPhone 7 is the ‘Lightning to Headphone Jack Adapter’. The new change brings some inconvenience to consumers, since they need one more adapter which is easily lost and broken. From the functional perspective, users cannot charge and use headphones simultaneously. That means if the iPhone is in low power and needs charging, the users have to stop all activities using headphones. Moreover, Bluetooth is also commented on negatively, which indicates that an improvement on this traditional function may be needed. Actually, the Bluetooth is a classical function of phones. However, the comments about Bluetooth is also complex. The wireless headphone relies on Bluetooth to connect with phone, and the related connection issues are possibly attributed to Bluetooth in users’ descriptions. Moreover, with the emergence of wearable products such as Apple watch and other health monitoring devices, they need to be connected to phones via Bluetooth. Therefore, the feedback related to the wireless devices and connection issues are unavoidably mentioned with Bluetooth by users.

These multiple functionality devices however, require external electricity/batteries to power them up. As the number of the applications increases, the power consumption increases, consequently limiting the duration in which the device can be utilized. An apple watch, for example, has most of the applications of a normal mobile phone, with additional features such as heart rate monitoring. The apple watch has a built-in rechargeable Lithium-ion battery that can last up to 18 h (at very minimal application usage) before requiring it to be recharged (Apple Inc, 2017)

In conclusion, results of the present study indicate that the Apple Watch 6 was the most accurate for measuring heart rate for all activities, whereas the accuracy of heart rate measurements varied between the different types of activities for the Polar Vantage V and Fitbit Sense (from high to poor accuracy). In addition, all 3 devices showed poor accuracy for assessing energy expenditure across all activities.
