Smartwatches With the Longest Battery Life

Go well over a day without charging your wearable

The Apple Watch received praise for many things when it first launched, but battery life isn't one of them. Rated for 18 hours of use between charge—for versions including the Apple Watch 2—this wearable needs to be plugged in every night. That cuts it for some, but it isn't ideal or convenient for everyone. Luckily, there are plenty of other options that let you stray from the cable for longer than a day. Read on to learn which smartwatches are your best bet when it comes to longevity.

What Is a Smartwatch and What Do They Do?

This one's a more recent entrant into the smartwatch space, and the company behind it made a big splash when it claimed its device can last up to 30 days. It's unclear how exactly the company managed such an impressive battery life, but apparently part of the equation is the proprietary, low-power operating system. 

Like with smartwatches, getting that extremely long battery life comes with some sacrifices, including settling for a black-and-white display rather than a color screen that delivers crisp and bright images. There's also no touchscreen. However, Vector has merged with fitness tracker giant Fitbit, so its future watches will likely bring more activity-tracking features to the table.

Vector Watch prices range from $219 to $349, and there's a huge variety of styles. Some of them are so classy they might be considered some of the most attractive smartwatches currently on the market.

The final smartwatch on this list is definitely on the expensive side. The Proximity sports a circular display and has the classic good looks you expect from a regular wristwatch, but it also has some high-tech features. When paired with your phone via Bluetooth, the device alerts you to any new calls, messages, emails, calendar reminders, and more.

The Proximity smartwatch was discontinued, but you may still find it via third-party resellers.

But let's get to the battery-saving feature: This watch is solar-powered, which means it works best when it gets sufficient exposure to light. In fact, Citizen warns that some of the watch's functions won't work as well when it doesn't receive enough sunlight, in order to preserve the watch's battery life. This might not sound exactly like a particularly smartwatch, and it's true: You do have to make several trade-offs. The advantage, though, is that you get months of battery life, so it's a win when it comes to convenience.
