The newest entry on this list, OnePlus followed up its lackluster original Watch from 2021 with this beauty, the OnePlus Watch 2, which more than makes up for the shortcomings of the original. Along with the rated 100 hours of battery life (or about 4 days), you can also flip it to Power Saver mode to extend that up to 12 days. Unlike with other smartwatches that shut down virtually every feature to save power, you'll still be able to access things like sleep tracking, heart rate, and even some fitness exercises as well as notifications.
Beyond that, it employs VOOC fast charging so you can be up and running in no time with a quick plug-in to the proprietary charging puck using the included charging brick. The dual-engine architecture, meanwhile, further extends battery life by using one chip to run basic background activities and others to kick in only when needed to run more complex apps, like maps or music controls.
Loaded with Google's Wear OS 4, you'll get plenty of pre-loaded Google apps along with others you can download right from the watch. That includes everything from Maps to even Google Assistant. Durable and elegant in design, the OnePlus Watch 2 is a sleek option to rival any of the best Android smartwatches on the market today.
How to choose
Which long battery smartwatch is best?
Why you can trust Android Central Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
Of course, youre going to choose the perfect smartwatch for you based on more than just battery life. But for some, thats a deciding factor between the two models you might be considering. If youre often away on adventures, youll benefit from a solar charging model like the Garmin Instinct 2 Solar.
All of the best Fitbit smartwatches offer good battery life, often at least a week, so you cant go wrong with that brand when it comes to the battery lasting for a good amount of time. The Fitbit Versa 4 is a good option to consider if you want premium features balanced with favorable battery life. Garmin makes fabulous smartwatches as well, like the Garmin vivoactive 4, and most of the brands smartwatches have batteries that last up to a week. Keep in mind that with the best running watches, from Garmin or other brands, using the built-in GPS can be a battery drain. But you still come out ahead.
From a budget standpoint, you cant go wrong with a brand like Amazfit, and the Amazfit Band 7 is a solid option for casual athletes and average users that youll love wearing. It employs more of a band design but still offers tons of smartwatch features. If you prefer the traditionally larger smartwatch screen instead, you can consider the Amazfit GTS Mini, which has the larger design and is still affordable, though it isnt as feature-rich as some of the other smartwatches on this list.
While the OnePlus Watch 2 works with any Android phone using 8.0 or higher, it's perfectly paired to a OnePlus device. (I used it with both the OnePlus 12 and the Google Pixel 8 and it works wonderfully with both). It's stylish, responsive, and you'll find that with regular, everyday use, you'll get through a full workweek before needing to recharge.
All the best Android smartwatches boast at least decent, at most amazing, battery life. Youll find that charging becomes part of your routine, whether it needs to be done daily, weekly, or less often. But the less you need to charge, of course, the better.
