Samsung’s official specs still rate the Galaxy Watch Ultra 2 at up to 60 hours with always-on display, matching the original model despite a battery increase to 800mAh from 590mAh.
The unchanged estimate comes even after Samsung swapped the watch to Qualcomm’s Snapdragon Wear Elite chip and shipped it with Wear OS 7, which had promised better efficiency.
Possible drains include the new 5,000-nit display—up from 3,000 nits—and a slightly higher 498x498 resolution, though those changes do not clearly explain the missing battery-life gain.
The same pattern appears in the broader lineup: Galaxy Watch 9 models got larger batteries and the same Qualcomm chip, yet Samsung still advertises up to 40 hours without always-on display across generations.
Samsung has not explained the discrepancy; if the figures are current rather than outdated marketing copy, they raise fresh questions about Snapdragon Wear Elite efficiency.
