OnePlus has announced that its Watch 3 will be available on February 18 in the US and Europe. The new watch boasts a battery life of five full days on a single charge.

That's up to 120 hours.

For comparison, my Pixel 3 watch is lucky to get thirty to forty hours on a full charge, and on days I go for long runs, that time is shortened to around 24 hours.

Having a watch that lasts 120 hours on a single charge could be a real boon, especially for those who travel a lot and don't want to pack yet another charger. And, according to 9to5Google, that time can be extended to 16 days by using the Watch 3's power savings feature.

Chips and batteries

The OnePlus Watch 3 makes this possible by employing two separate chips: A Snapdragon W5 and a BES2800 MCU. Note that the BES2800 MCU is an efficiency chip, which means it's not as powerful as those used in flagship watches. However, if you need long battery life for your wearable, the OnePlus Watch 3 will be the one to beat.

When you couple the efficient chips with a new Silicon NanoStack Battery (which moves the watch's battery from 500 mAh to 631 mAh) battery life on the Watch 3 will be hard to beat.

Along with the extended battery life, the Watch 3 now sports a titanium alloy bezel and a Sapphire Crystal display that will be available in two colors: Emerald Titanium and Obsidian Titanium. There's also a new rotating crown that makes it easier to navigate the menu system. This should be considered a big move forward, given the crown on the previous OnePlus watches wasn't capable of scrolling through menus.

Price and availability

As far as price goes, there's no indication on the official site, but you can subscribe to what I'm assuming is the OnePlus newsletter to get$30 off the watch.
