Over 30% Larger Display
The display is the defining feature of Apple Watch, and Series 4 pushes it further than ever. The challenge was to make it bigger without noticeably increasing the size of the case or compromising the battery life. Narrower borders enable a viewing area that’s over 30 per cent larger, while a new display technology called LTPO improves power efficiency, helping you get through the day on a single charge.
Optical Heart sensors
The optical heart sensor has been part of Apple Watch from the beginning, allowing you to quickly check your heart rate. Now it can also detect if your heart rate falls below a specified threshold for a period of 10 minutes when you appear to be inactive, triggering a low heart rate notification. This can be a sign of bradycardia, which can be serious if the heart is not pumping enough oxygen-rich blood around the body.
S4 SiP with a Faster 64-bit Dual-Core Processo
The S4 is more than just a processor. It’s a complete Silicon in Package (SiP), with the entire system fabricated onto a single component. This architecture allows Apple Watch to pack amazing capabilities into a tiny space. In fact, Apple Watch is the only product in the world that runs completely on a SiP.
