An official specification sheet shows that, despite what has been claimed this week in the event of a third party failure, the Series 4 has lowered the battery capacity slightly compared to the Series 3, even if it does not seem to affect the operating time.
The battery cell in the 44 mm series 4 has a power of 1.12 watt-hour compared to the 1.34 of the 42 mm-series 3, the blade indicates. Similarly, the 40 mm series 4 only has 0.86 watt-hour versus the 38 mm series 3 & # 39; s 1.07.
Apple is launching the Series 4 on the market when it achieves the same battery life of 18 hours as before. This is probably due to an improved energy consumption, for example due to the introduction of LTPO (low temperature polycrystalline oxide) for its display.
The sheet is marked by MacRumors earlier today.
Better battery life is still one of the most common requirements for the Apple. Models can sometimes take two days or longer with light use, but only a day or less when people benefit from demanding functions such as training or mobile phone calls. Rival smartes, like Fitbit's, can run for three or four days, even with the addition of extra functions, such as sleep monitoring.
