When you're choosing the best Apple Watch in terms of battery life, there's only one place to look. The Apple Watch Ultra 2 can run for longer than any other Apple wearable between visits to the charger and it's the model to go for if battery life is a key feature for you. But as strong as the Apple Watch Ultra 2's 36-hour battery life (or 72 hours in Low Power Mode) might be, it still isn't the best you can find in a smartwatch. Not by a long shot.
That's something that has been very much proven following the unveiling of the new OnePlus Watch 2, a product that was shown off for the first time at the ongoing Mobile World Congress (MWC) event in Barcelona, Spain. The wearable, which is obviously aimed more at Android phone owners than those carrying an iPhone 15, has battery life for literal days. Days upon days, in fact.
