Samsung's galaxy watch ultra 2: a massive battery boost masking a charging nightmare
Samsung’s latest Galaxy Watch Ultra 2 promises a three-day battery life, a significant leap from its predecessor. But that impressive longevity comes at a steep price: a frustratingly slow charging speed that threatens to negate the benefits of its expanded power reserves.
The hype around 800mah – and why it matters
Rumors of a 35% increase in battery size, swelling from the Ultra’s 600mAh to a hefty 800mAh, were met with considerable excitement. The Ultra 2 managed to achieve this upgrade without significantly increasing the watch's dimensions – a genuine feat of engineering. And, frankly, the extended battery life is a welcome change, offering users a tangible advantage over competitors like the Apple Watch Ultra.
The charging conundrum
However, the reality of charging this new powerhouse is far less appealing. Our testing, using Samsung’s own magnetic charging puck and a 25-watt charger, revealed a painfully protracted four-hour charge time. It’s a stark contrast to the swiftness we’ve come to expect from modern smartwatches and a considerable disappointment for a device boasting such impressive stamina.
A comparative look
Let's put this into perspective. While a larger battery demands more time to recharge, four hours is simply unacceptable. The Apple Watch Ultra 3, for example, can return 55-60% charge in a 30-minute burst, and even the aging Apple Watch Series 11 can achieve an 80% top-up in the same timeframe. The Google Pixel Watch 4 offers similarly rapid charging, delivering around 80% in just 30 minutes. Samsung’s approach leaves a considerable gap, transforming what should be a liberating feature into a genuine inconvenience.
The ecosystem equation
Smartwatches are fundamentally 24/7 devices – constantly monitoring sleep, tracking activity, and providing health insights. Users expect a quick, convenient top-up to sustain this continuous operation. Apple and Google have prioritized faster charging speeds precisely because of this demand. Samsung’s slow charge rate undermines the very premise of a device built for constant wear.
The bottom line
Samsung has undeniably addressed battery anxiety with the 800mAh powerhouse, but simultaneously introduced a new frustration: charging anxiety. The promise of three days of use is compelling, yet the extended charging time renders it significantly less appealing. It’s a classic case of a brilliant feature overshadowed by a critical flaw – a truly wasted opportunity. This isn't innovation; it's a demonstrable oversight that could significantly impact the Ultra 2’s overall success.
