“Sleep Score” is a major health feature that has graced watchOS 26. Though Apple showcased it as one of the major highlights of the Apple Watch Series 11, SE 3, and Ultra 3, it’s not restricted to the latest watchOS devices. That means so long as your watch is running the watchOS 26 update, you can view the Sleep Score on any Apple Watch model. If that’s what you are looking for, follow along to get started:
1. To begin, launch the Health app on your paired iPhone.
2. Now, tap on the “Summary” tab at the bottom.
3. Then, head over to the Sleep category and select Sleep Score.
4. It’s worth highlighting that Apple measures sleep quality with ratings of Excellent, High, OK, Low, or Very Low, based on three key factors:
- Sleep duration (50 points)
- Bedtime consistency (30 points)
- Sleep interruptions (20 points)
Keep in mind that points are deducted if you sleep too little, go to bed late, or experience frequent interruptions.
- Excellent means you achieved enough restorative rest.
- High indicates you slept well overall.
- OK suggests your rest was insufficient.
- Low points to poor sleep quality.
- Very Low signals a serious sleep deficit that may impact your physical and mental health.
The Sleep Score can be calculated using data from an Apple Watch or any third-party device that records sleep in the Health app—so while an Apple Watch helps, it’s not strictly required.
Frequently Asked Questions
Q1. Can I wear my Apple Watch while swimming or showering?
Yes, most Apple Watch models (Series 2 and later, including the Ultra) are water-resistant and can be used for swimming in pools or open water. However, they are not designed for high-velocity water activities like water skiing or deep-sea diving. It’s also best to avoid wearing them in hot tubs or saunas.
Q2. Does the Apple Watch work without an iPhone?
You can use many features like fitness tracking, music playback, alarms, and Apple Pay without an iPhone nearby. However, for calls, messages, and app updates, you’ll need either your iPhone or a cellular-enabled Apple Watch with an active plan.
Q3. How often should I charge my Apple Watch?
Most Apple Watches last about 18 to 36 hours, depending on the model and usage. Daily charging is recommended, though some models like the Ultra may last longer with optimized settings. Using Low Power Mode can extend battery life when needed.
