Apple Watch Series 6 & Apple Watch Series 4 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Apple Watch Series 6 rather than the Apple Watch Series 4.
Why Do I Recommend The Apple Watch Series 6?
- The Apple Watch Series 6 features the S6 SiP processor for faster app loading and smoother overall performance, whereas the Apple Watch Series 4 uses the older S4 chip.
- Apple Watch Series 6 has an Always-On Retina Display for quick time and metric visibility without wrist movement, while the Apple Watch Series 4 uses a standard display.
- It includes a Blood Oxygen Sensor to monitor SpO2 levels for better wellness insights during sleep and workouts, whereas the Apple Watch Series 4 has no blood oxygen measurement capability.
- The Apple Watch Series 6 supports dual-band Wi-Fi (2.4GHz and 5GHz) for stronger and faster wireless connectivity in crowded networks, while the Apple Watch Series 4 supports only 2.4GHz Wi-Fi.
- Apple Watch Series 6 has 32GB internal storage to keep more music, apps, and podcasts accessible offline, whereas the Apple Watch Series 4 comes with 16GB storage.
- It comes with an Always-On altimeter to display real-time elevation during activities like hiking and climbing, while the Apple Watch Series 4 includes a traditional altimeter that does not continuously update elevation.
- The Apple Watch Series 6 supports faster charging to reduce downtime and allow more time being worn for fitness and sleep tracking, whereas the Apple Watch Series 4 uses slower charging.
- Apple Watch Series 6 includes the U1 Ultra-Wideband chip for improved device location precision and better future-proofing for ecosystem features, while the Apple Watch Series 4 has no U1 chip.
Maybe the Apple Watch Series 4 can make you comfortable because it’s a little bit cheaper than the Apple Watch Series 6. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
