Apple Watch Ultra 4 Arrives in Nepal With Better Battery Life

The Apple Watch Ultra 4 has finally arrived in Nepal, following its global launch in September 2026. As the successor to the Ultra 3, expectations are ultra high.

The Ultra 3 had earned a solid reputation as an adventure watch. But battery life made potential buyers think twice, especially compared with the Garmins of the world.

Does Apple address the Ultra 3’s shortcomings with the Ultra 4 and make a stronger case for itself? But before that, let’s take a look at what it costs.

The Ultra lineup has generally lived up to its rugged, feature-packed reputation, but its predecessors haven’t been without their shortcomings. So, I’m curious to see what Apple has improved this time around, and whether anything that needed fixing has been left untouched.

Let’s take a closer look!

Apple Watch Ultra 4 Overview

Apple has kept the Watch Ultra 4’s design consistent across generations. Put the Ultra 4 and Ultra 3 side by side, and you’d be hard-pressed to tell them apart. Both retain the same 49mm Grade 5 titanium case, raised Digital Crown housing, and orange Action button.

The Ultra 4 is available in Natural Titanium and Black Titanium, both with a satin finish. The black version gets a diamond-like carbon coating for added scratch resistance, while the titanium case is 3D-printed layer by layer to reduce material waste.

The Ultra’s design has its perks beyond looking rugged, too. Its exclusive Wayfinder and Modular Ultra watch faces make good use of the large display. Wayfinder doubles as a compass and turns red in Night Mode for better visibility in the dark, while Modular Ultra squeezes extra information like seconds, altitude, and depth around the screen’s outer edge.

The Ultra 4 has grown slightly heavier. The Natural Titanium version goes from 61.6 grams on the Ultra 3 to 63 grams, while the Black Titanium version jumps from 61.8 to 63.1 grams. The Ultra 3 was already criticised for feeling bulky; adding weight isn’t exactly the direction we’d have hoped for.

The Ultra 4 carries over the Ultra 3’s 49mm Always-On Retina OLED display with LTPO3 technology, and 1-nit minimum and 3,000-nit peak brightness. The display is protected by a sapphire crystal as always.

The Ultra 4 carries forward its predecessor’s strongest features. It’s designed to operate in temperatures ranging from -20°C to 55°C and has been tested against selected MIL-STD-810H environmental conditions.

It also carries an IP6X dust-resistance rating and meets the EN13319 standard. As such, it is WR100 water-resistant and can support high-speed water sports and recreational scuba diving to 40 meters.

Those numbers may look mind-blowing, but they aren’t major upgrades, since the Ultra 3 already offered all these core display and durability features.

The Ultra 4 gets Apple’s newer S11 chip, replacing the Ultra 3’s S10. The internal cores on both chips may be the same, but their capabilities definitely are not. The new chip is derived from the latest A20 Pro chips and has higher bandwidth.

All this translates to improved step tracking, smarter health features, and new Audio Intelligence tools. One of the more interesting additions is Live Rewind, which lets you revisit a transcript of the previous 15 seconds of a conversation, alongside Siri Recap for summarising key points.

Live Rewind and Siri Recap features won’t arrive until beta in late 2026. Likewise, you’ll also need an Apple Intelligence-enabled iPhone 16 or later (excluding the iPhone 16e) to use them.

The Ultra 4 features a new Health Sensing System which measures heart rate every five seconds throughout the day, while HRV readings are available up to 24 times more frequently than on the Ultra 3. Apple claims it offers the most accurate heart-rate tracking of any Apple Watch to date.

Another interesting addition is Readiness, a score from 0 to 10 that considers your recent activity, training load, vital measurements, and sleep. It then suggests whether to recover, pace yourself, or go for it.

Apple has also redesigned its step-counting system to improve step counts and distance estimates, particularly during indoor walks and runs. The Ultra 4 retains ECG readings, blood oxygen monitoring, temperature sensing, sleep stages, and sleep scores, alongside notifications for possible sleep apnoea and hypertension.

But these aren’t exclusive perks to the Ultra 4 only, as the standard Apple Watch Series 12 also gets the new Health Sensing System, Readiness, and improved step tracking, too.

For outdoor activities, the Ultra 4 offers dual-frequency GPS, offline maps, compass waypoints, and Backtrack to retrace your route. Apple claims it delivers the most accurate GPS of any sports watch, though the Ultra 3 already had dual-frequency GPS.

It supports running, cycling, swimming, and recreational diving up to 40 metres. The Depth app tracks depth and water temperature, while Fall Detection, Crash Detection, Emergency SOS, and an 180-metre emergency siren add safety features.

Satellite connectivity can be useful for remote treks, but Emergency SOS via satellite isn’t currently supported in Nepal. Many of these outdoor features also carry over from the Ultra 3.

Battery life has long been one of the Apple Watch Ultra’s biggest weak points. With the Ultra 4, Apple has finally squeezed out more endurance.

It lasts up to 50 hours, compared with 42 hours on the Ultra 3. That’s an extra eight hours, or roughly a 19% improvement. Low Power Mode now stretches battery life to 84 hours, while Max Extended Workout supports up to 45 hours of tracking. Charging has improved, too, with a 15-minute top-up offering up to 18 hours of use, compared with 12 hours on the Ultra 3.

The Apple Watch Ultra 4 runs watchOS 27 and is designed to work with compatible iPhones. Apple lists compatibility with the iPhone 11 or later, including the second-generation iPhone SE or later, running iOS 27 or later.

It supports cellular connectivity, 5G, dual-frequency GPS, Bluetooth 5.3, and a second-generation Ultra Wideband chip. The latter supports features such as Precision Finding for a misplaced compatible iPhone.

So, has Apple finally fixed the Ultra’s battery problem? Not quite. The jump from 42 to 50 hours is a step in the right direction, but the Samsung Galaxy Watch Ultra 2 — the only real competitor for the Apple Watch Ultra in Nepal — pulls ahead.

Samsung rates it for up to 60 hours with Always-On Display enabled and 80 hours with it disabled, with fast charging that hits 40% in around 30 minutes. It also works with Android phones, which remain the majority in Nepal.

But if you are the kind of person who is keen on getting the Apple Watch Ultra 4, however much it costs, it is safe to assume you already have an iPhone. In that case, the Ultra 4 is undoubtedly the most capable package with improved health tracking, a Readiness score, and better battery life than before.

Then again, do take a moment to consider whether you actually need all that capability, like the scuba diving depth tracking. Also, are you fine carrying all that heft on your wrist on the daily? If not, most of the meaningful health upgrades are already on the Series 12. Maybe that’s the better pick for you.
