Apple Watch Ultra 2 battery and charging: What you need to know
The first Apple Watch Ultra, released in September 2022, was an important watershed moment for Apple. It marked the arrival of its first truly premium smartwatch, which not only set itself apart with a couple of unique features, but also boasted an improved design with a much larger titanium case with a sapphire screen and a much larger battery inside. 

With a dedicated dive computer, a more precise GPS, a customizable Action Button, and a super-loud siren that will alert anyone in your immediate vicinity of your whereabouts, the Apple Watch Ultra is quite different from the rest of the Apple Watch lineup. 

Now that the Apple Watch Ultra 2 is official, it's clear as day that Apple is gearing towards yearly updates for its rugged lineup of super-premium smartwatches. Not that we're complaining, no; in fact, the pioneering Apple Watch Ultra reinvigorated our collective interest in Apple's wearables and received high praises for its expertise.

  • 564mAh

The Apple Watch Ultra 2 comes with a 564mAh battery inside. It doesn't deliver much better battery life than the first Apple Watch Ultra, though, and still allows for up to "180 time checks, 180 notifications, 90 minutes of app use, and a 60-minute workout with music playback from Apple Watch via Bluetooth, over the course of 36 hours. Apple also says thatApple Watch Ultra 2 (GPS + Cellular) usage includes a total of 8 hours of LTE connection and 28 hours of connection to iPhone via Bluetooth over the course of 36 hours."

In our experience, and as far as regular everyday usage goes, the Apple Watch Ultra 2 is good enough for two to even three days of usage, depending on how hard you utilize all of its hardware and software features. Once the honeymoon phase is over and you don't play around with it too much, you'll definitely see longer periods between charges.

In terms of charging, the Apple Watch Ultra 2 supports fast charging with a compatible USB Type-C to MagSafe-puck cable and at least a 20W wall adapter. 

Yet, unlike regular Apple Watches, the Apple Watch Ultra takes a bit longer to charge as it has a larger battery in comparison. All in all, it takes roughly an hour and a half to fully top up the Apple Watch Ultra. If you don't want to wait that long, a completely usable 80% charge that also goes easier on your battery takes around an hour.
