Samsung's wearable offerings are probably the best alternatives to the Apple Watch. Its partnership with Google for the Wear OS-based Galaxy Watch4 series seems to have done wonders for everyone involved, as the company achieved its highest quarterly smartwatch shipments last year. However, battery life is one of its Achilles' Heel as it is not big enough to last a couple of days nor does it charge quickly. A leak from a couple of weeks ago hinted that the 40mm Galaxy Watch5 could sport a bigger battery to fix this issue. Another leak today confirms that the 44mm variant of the watch will also ship with a bigger battery.

The initial leak was spotted by the folks over at SamMobile in a South Korean regulatory filing, revealing that the watch will house a 276mAh unit, a step-up from the 247mAh cell found inside the Galaxy Watch4. The latest leak also comes courtesy of a listing in Safety Korea's database (via SamMobile). It confirms that the 44mm Galaxy Watch5 carrying the model number EB-BR910ABY will feature a 397mAh battery, a decent upgrade from the 44mm Galaxy Watch4's 361mAh cell. There's no information on the Classic variant yet, but with any luck, it'll also have a beefier battery.

All that said, an increase in battery capacity simply doesn't translate into better battery life. It also depends on factors like the efficiency of the chipset and the hardware it's pushing. The addition of new sensors — including a rumored skin thermometer meant to measure body temperature on the fly — could defeat the gains made with the larger battery capacity.

Even though information about the watch has started to trickle out, it's unlikely that the Watch5 will be released soon. If the company sticks to its usual calendar, we can expect them to be unveiled at an Unpacked event in the third quarter of 2022. The rumor cycle around the watch has picked up the pace, so expect to hear more about it in the coming weeks.
