When it comes to smartwatches, the expectation is generally that one can wear them throughout the entire day without fail. Hence, one of the most important features of a smartwatch is its battery life: if the battery dies in 2 hours, what good is the watch at all?

However, battery life is a very nuanced thing, especially in the field of smartwatches where they are not all designed for the same purposes. Generally speaking, the more functionality a watch has, the less battery life it has - marking a notable tradeoff for consumers.

For example, an Apple Watch might be designed for standard tasks like texting, calling, and running other apps, while a Whoop watch might solely care about tracking health. As a result, the Apple Watch prioritizes its display, leading to greater energy consumption and shorter battery life. Meanwhile, a Whoop watch doesn’t even have a display, so it naturally will have a longer battery life.

Naturally, this begs the question: what even constitutes a “smartwatch”? In this piece, we’re going to look at the smartwatches with the best battery life on the market in 2023. In an attempt to level the playing field, we’re only going to consider watches with displays, since the display is generally the number one consumer of power in a device.

Read on to learn about seven smartwatches with the longest battery life in 2023.
