The Apple Watch is considered the best-selling watch in the world. In addition to a redesign, the Apple Watch Series 4 boasted the ECG function.
Apple has now published a comprehensive support document for the new Apple Watch. There are also interesting details about the battery. According to the report, it is 20 percent smaller than in the 3rd generation.
Apple Watch Series 3 (42mm): 1.34 Wh
Apple Watch Series 4 (44mm): 1.12 Wh
Apple Watch Series 3 (38mm): 1.07 Wh
Apple Watch Series 4 (40mm): 0.86 Wh
Despite the lower battery capacity, there is no negative impact on the running time of the Apple Watch Series 4. The reason for this lies in the technology. The S4 chip is significantly more efficient than its predecessor. In addition, the new LTPO OLED display (Low-Temperature Polycrystalline Oxide) is considered to be particularly energy-efficient.
