It's Time For Battery Life of Samsung Galaxy and Apple Smart Watches To Improve

It's time for the rapid pace of battery advancement to start showing up in smart watches, especially Apple Watches, whose batteries fall far short of Samsungs. Oddly, Apple has pretty much avoided upgrading the battery of the iPhone, resulting in the watches inconveniently having to be charged daily.

Samsung Galaxy Watch 6 vs. Apple Watch Series 9

Samsung Galaxy Watches have approximately 2.25 times the battery duration of Apple Watches, showing the need for Apple to prioritize a substantial upgrade to their watch battery technology.

The Apple Watch Series 9 currently provides only about 18 hours of battery life, while the Samsung Galaxy Watch 6 boasts up to 40 hours.

A Single Charge Will Provide Smart Watches With Enough Battery Life to Last A Week

With advances in battery technology, it's a matter of a few years before these watches should work for a week on a single charge.

"TDK, the largest maker of smartphone batteries in the world, said Monday that it has successfully developed a material that could be used in a new battery with “significantly higher energy density” than its existing cells. Energy density refers to how much energy a battery can store relative to its size or weight. The material will be used in TDK’s CeraCharge solid-state battery, which it says has an energy density of 1,000 watt-hours per liter — approximately 100 times more than its conventional solid-state battery." - via Quartz

Overall, advancements in battery technology, such as improvements in lithium-ion chemistry and packaging, continue to drive higher energy densities, enabling longer battery life and smaller form factors in modern watches, particularly smartwatches.
