Apple Watch Ultra Battery Life: Key Facts and LTE Impact

Apple has really stirred up excitement with its new Apple Watch Ultra. This impressive piece of tech marks Apple’s biggest redesign of the Apple Watch since it first hit the market. With its rugged build, dedication to adventurous activities, and surprisingly long-lasting battery, the Apple Watch Ultra is ready to make a statement at its official launch later this month. Before this big debut, though, some regulatory filings have given us a sneak peek at its impressive specifications.

Exploring the Apple Watch Ultra’s Battery Capacity

The folks over at MySmartPrice were among the first to share some tantalizing details about the Apple Watch Ultra’s battery. These specifications reveal that this smartwatch sports a battery that’s a whopping 76% larger than the one you’d find in the 45mm Apple Watch Series 8, and an astounding 92% larger than the 41mm version. With numbers like these, it aligns perfectly with Apple’s promise of the Apple Watch Ultra lasting up to 36 hours on a single charge. That’s double what the Series 8 offers!

Using LTE with the Apple Watch Ultra

If you’re curious about the Apple Watch Ultra’s battery performance with LTE, trust me, you’re not alone! Apple officially claims up to 36 hours of battery life, but this figure isn’t quite set in stone. Once you activate LTE, expect some adjustments. According to Apple, the Apple Watch Ultra can run for around 18 hours on LTE alone. That’s pretty good for keeping you connected all day long!

As Apple explains, their 36-hour battery estimate hinges on a blend of 8 hours using LTE and 28 hours connected to an iPhone via Bluetooth over that period. It’s interesting to note that Apple hasn’t revealed similar LTE-only battery details for the Apple Watch Series 8, despite providing an 18-hour figure based on 4 hours of LTE usage paired with 14 hours of Bluetooth connection over the same timeframe.
