Apple Watch Battery Comparison Chart: Size, Battery Life and Charge Time

By Daniel Segun •  Updated: 12/12/21 •  5 min read

Several Apple Watch models have been released over the years. For your next Apple Watch purchase, you should check out the battery’s capacity, how long it lasts, and how long it takes to charge. Here’s a simple Apple Watch battery comparison chart…


The Apple Watch is the world’s most popular wearable. As smartwatches go, the Apple Watch is normally what people think of when they hear the term smartwatch. However, as you will see in this guide, the Apple Watch does have one small problem: battery life.

The battery life on the Apple Watch – even Apple’s latest models – is not very good. With Apple Watch, you will have to charge up the wearable every day – or every other day if you’re lucky. The reason for this, however, is simple: Apple Watch does a lot of stuff but it has a small battery.

Apple clearly sees the Apple Watch’s many features and abilities as a fair trade-off for battery life. Me? I prefer a wearable that doesn’t need charging every 24 hours. This is why I use Garmin watches which not only last way longer (anywhere from a week to a month, depending on the model) but they are also far better at tracking your running activities.

Still, Apple Watch is immensely popular. And in the table below, you can see how big the battery is inside each of Apple’s Apple Watch models, as well as how long it takes to charge up.

And if you’re looking to compare the SIZES of different Apple Watch models, Check out our complete list of Apple Watch sizes here.

From the Apple Watch 1st generation, there have been five more generations of the Apple Watch produced. Here are the differences:

Wrapping Up…

Apple Watch battery sizes of the same series are more similar than others. The charge time and all-day battery life of the earlier series are about the same, and the same goes for the previous versions. Only the bigger 42mm version of the Apple Series 2 and 3 Watches has a battery size of up to 300 mAh.
