Samsung's galaxy watch ultra 2 boasts record-breaking 35% bigger battery, but charging times are abysmal

Samsung's latest smartwatch, the Galaxy Watch Ultra 2, is packing an unprecedented 800mAh battery, a 35% increase from its predecessor. This sonic boom in stamina has been hailed as a major coup for the Korean tech giant, allowing the device to last a record-breaking three days on a single charge.

But there's a catch: slow charging times put a damper on the experience

While a three-day battery life is an impressive feat, it's rendered nearly useless when paired with sluggish charging times. In our tests, the Galaxy Watch Ultra 2 took a mind-boggling four hours to fully recharge using Samsung's 25-watt charger and magnetic puck.

This slow charging pace is particularly egregious for a smartwatch designed to be a 24/7 companion. With modern smartwatches catering to users who wear them all day and night, charging windows become increasingly hard to find.

Apple and Google have both recognized this issue, focusing on delivering faster charging speeds to their respective smartwatch offerings. In contrast, Samsung's Galaxy Watch Ultra 2 struggles to provide a quick top-up, let alone a full charge in under an hour.
