The battery of the upcoming Apple watch series 6 is likely to have been filed with Korea Testing Institute and discovered by twitter user @ yabhishekhd.On june 23rd south korea's regulatory agency KTR certified a unit of 1.17 Wh with a capacity of 303.8 mAh, which approves and tests new hardware before it is sold publicly.
Judging from the shape, capacity and size of the A2327 battery, the battery seems destined for future Apple Watch. The current Apple Watch Series 5 battery capacity is 296 mAh, the model is A2181, visually the same. Batteries are also listed in the declaration
The 303.8mah capacity of the new Apple watch will be larger than that of previous generations. This can be compensated for by canceling the force touch sensing layer, which has actually failed in watchos 7. In the future Apple watch, without this component, the internal space can be made available for a slightly larger battery.
Apple claims that the apple watch series 5 provides 18 hours of battery life, but since the new battery is only slightly larger, it is unlikely that there will be a significant increase in the battery life of the series 6. For a compact device like the apple watch, any significant improvement in battery life is more likely to come from improved power efficiency than from larger batteries.
Earlier this week, it was rumored that the apple watch series 6 might have blood oxygen monitoring, which could consume more power and require larger batteries.
The apple watch series 6 model, which is expected to be launched in the fall, is said to have faster performance, better water resistance, and improved wireless transmission for faster Wi Fi and cellular speeds.
