Apple Watch Series 7 to Focus on One Major Upgrade
The upcoming Apple Watch Series 7 will focus on one important feature in an attempt to tempt existing Apple Watch users that have an older device to upgrade, according to recent reports.
Apple may skip adding new health sensors to this year's Apple Watch Series 7 in favor of improving the device's battery life. The company is said to be adopting new double-sided System in Package (SiP) technology to reduce the size of Apple Watch's processor. Economic Daily News claims that the smaller "S7" chip will free up internal space for a battery with a larger capacity or additional health sensors.
Since Apple is now believed to have delayed the introduction of new health sensors like blood glucose and body temperature monitoring until 2022 at the earliest, the freed up space is more likely to facilitate a larger battery.
Reliable Apple analyst Ming-Chi Kuo has previously said that the Apple Watch Series 7 could feature a significant redesign. The new design could include a flatter case, similar to the iPhone 12 or the iPad Pro, that may increase internal space for a larger battery.
The 44mm Apple Watch Series 6 uses a 1.17Wh battery that is 3.5 percent larger than the battery in the same Series 5 model, while the 40mm Apple Watch Series 6 includes a 1.024Wh battery that is 8.5 percent larger than the battery in the Series 5.
Despite having faster charging speeds, the addition of new features and sensors in successive Apple Watch models has seen battery life stay relatively constant over the years. As with previous Apple Watch models, Apple advertises the Series 6 as offering "all-day" battery life up to 18 hours.
One reason to prioritize battery life for the Series 7 could be to heavily promote the improvement in order to lure owners of older Apple Watch models to upgrade. This could be particularly attractive to users who have an Apple Watch with a battery that has gradually deteriorated over the years due to normal chemical aging.
Increasing the battery capacity could also allow Apple Watch to better compete with rival smartwatches that tend to market their multi-day battery life as a tentpole feature, such as the Fitbit Versa 3, which can work for over six days on a single charge.
Aside from potential battery improvements, Apple Watch Series 7 is also expected to feature improved wireless and Ultra Wideband connectivity, slimmer display bezels, and the use of a new lamination technique that brings the display closer to the front glass, with updated screen technology.
