Dozens of brands offer smartwatches under $100, and it's no easy task to figure out which ones are worth spending your hard-earned money on, regardless of your budget. Battery life is also an important consideration when choosing one, even when you're looking for a more affordable option. We looked into the most affordable smartwatches with the best battery life and found two standouts: the Amazfit Bip 6 and the Xiaomi Redmi Watch 5, both of which claim up to 14 days of battery life, but realistically last somewhere between seven and 10 days.

To find the most affordable smartwatches with the best battery life, we considered manufacturer claims and also did our own research. No one wants their smartwatch dying while they're going about their day. Ideally, a smartwatch's battery will last several days before it needs to be charged.  We scoured verified reviews for budget smartwatches and read discussions on forums like Reddit, where several people have shared their experiences with different brands and models. According to the manufacturers, these watches can last at least two weeks on a single charge, and in real-world tests by verified customers, they lasted roughly a week or more.

The Amazfit Bip 6 is a fitness-tracking smartwatch with GPS capabilities, and Amazfit says it lasts up to 14 days with normal use. Consumer Reports recommends the Bip 6 as the best budget-friendly smartwatch, too. Reviewers say that even with heavy use, the watch lasts them five days or more before it needs a recharge, and it charges quickly, too. The watch currently costs $79 on Amazon. We couldn't find any reviewers who mentioned their Amazfit lasting a full two weeks on a single charge, but the 5 to 10-day battery life many customers report is impressive regardless.

The Xiaomi Redmi Watch 5 is a basic smartwatch that provides phone notifications and tracks your steps, activity, sleep, and heart rate. It lacks GPS capabilities, but it's also very affordable at just under $45. Xiaomi doesn't make any specific claims about battery life on the product's Amazon page, but the Xiaomi website claims the battery can last for up to 18 days.  According to several customer reviews, the battery can easily last for a week or more on a single charge, or much longer in battery saver mode.
