HIGHLIGHTS
- The Exynos W920 was debuted in the Samsung Watch 4 generation.
- A 276mAh battery might be found in the Samsung Galaxy Watch 5 40mm.
- The 44mm model might have a 397mAh battery.
The battery life of Samsung's Galaxy Watch 4, which gives the first experience built on top of Wear OS 3 and has some pretty nice features, isn't the best.
According to SamMobile, the South Korean tech giant is planning to release the Samsung Galaxy Watch 5 with significantly bigger batteries for the 40mm and 44mm variants.
According to a Safety Korea certification, both sizes will be enhanced in the following generation. It will be another incremental enhancement; week-long battery life for full-fledged smartwatches is still not realistic.
The Samsung Galaxy Watch 5 40mm (EB-BR900ABY) battery will be 276mAh, up from 247mAh (+29mAh). The battery of the bigger Watch 5 44mm (EB-BR910ABY) will be 397mAh, up from 361mAh (+36mAh).
Of course, battery life is determined by two factors: battery capacity and hardware efficiency. The Exynos W920, a 5nm processor launched in the Watch 4 generation, is more efficient than the 10nm Exynos 9110 used in the Watch 3 series and the 12nm Snapdragon Wear 4100 used in certain non-Samsung watches.
According to reports, 4nm foundries are nearing capacity, therefore a new, more efficient wearable chipset is improbable.
According to previous rumours, Samsung has discovered a method to incorporate a thermometer inside the next-generation watch, which will be used to check skin temperature, important for detecting early indications of illness and tracking ovulation cycles. The Galaxy Watch 5 will not be released until the second half of this year.
