You just strapped a tiny supercomputer to your wrist. It’s sleek. It’s expensive. Honestly, it’s probably buzzing way too much right now. Most people live with the out-of-the-box experience because they assume the default is the "correct" way, but that is a massive mistake. If you want to change settings on Apple Watch, you shouldn't just be looking for a toggle; you should be looking for a way to make the device stop annoying you and start actually helping you.
Apple’s interface is famously "simple," yet finding the specific menu to stop your watch from shouting your heart rate during a workout can feel like a labyrinth. There are two ways to do this. You can use the Watch app on your iPhone—which is usually easier for heavy lifting—or you can dive into the Settings app on the watch itself. Some things, like specific Accessibility tweaks, are actually buried deeper than you'd expect.
The Master Hub: iPhone vs. On-Wrist
Basically, your iPhone is the brain. If you open the Watch app on a paired iPhone, you get a sprawling list of every possible adjustment. It’s better for when you’re sitting on the couch and want to reorganize your entire app layout or fine-tune notification privacy. On the flip side, the on-wrist Settings app (the grey gear icon) is for quick fixes.

How to Change Settings on Apple Watch for Better Battery Life
Battery anxiety is real. You don't need a degree in electrical engineering to see why an Always-On display drains juice. To change this, tap the Digital Crown to see your apps, hit Settings, and scroll to Display & Brightness. Flip the switch on Always On.
But wait. There’s a nuance here most people miss.
You don't have to kill the feature entirely. Within that same menu, you can choose to hide sensitive complications or block certain apps from showing data while your wrist is down. It’s a middle ground. If you’re a runner using the Apple Watch Ultra 2 or a Series 10, you might also want to look at "Low Power Mode" in the Battery section of settings. It doesn't just dim the screen; it actually throttles the background heart rate sensor and GPS polling.
Real-world tip: If you’re hiking and need the battery to last 48 hours, turning off the "Wake on Wrist Raise" feature is the single most effective move you can make. It stops the screen from firing up every time you move your trekking poles.
Silencing the Noise
Notifications are the death of productivity. By default, your watch mirrors your iPhone. That’s usually a nightmare. To fix this, you have to go to the Watch app on your iPhone, tap Notifications, and start ruthlessly toggling things off.
Some apps don't need to be on your wrist. Does your Starbucks app really need to vibrate your arm? Probably not. Scroll down to the "Mirror iPhone Alerts From" section and kill everything that isn't a "must-see" within ten seconds of receiving it.
The Complication Confusion
The "Watch Face" isn't just a clock. It's a dashboard. To change settings on Apple Watch faces, you don't actually go into the Settings app. You long-press the current face.

Tap Edit.
Now you’re in the customization engine. Swipe left to reach the "Complications" screen. These are the little widgets—weather, battery, rings. This is where the Apple Watch becomes a tool. If you’re a pilot, you put Zulu time there. If you’re a parent, maybe it’s a one-tap shortcut to call your spouse.
According to Kevin Lynch, Apple's VP of Technology, the goal of the watch was "brief interactions." If you’re spending more than five seconds looking at a watch face to find info, your settings are wrong. Simplify.
Sound and Haptics: The Stealth Mode
Go to Settings > Sounds & Haptics.
Most people hate the "Chimes" feature that dings every hour. Turn that off.
Conversely, "Prominent Haptic" is a lifesaver. It gives you a "pre-tap" before the actual notification hits. It feels like a subtle tug on your skin. It's much more human than a jarring vibration.
And for the love of everything, turn on Tap to Speak Time. If you hold two fingers on the watch face, it’ll whisper the time to you. It’s great for boring meetings.
Health and Safety Toggles You Must Check
Apple has been leaning hard into the "health device" branding. But some of these features are tucked away.
- Fall Detection: If you’re under 55, this is often off by default unless you’re working out. Change this in Settings > SOS.
- Heart Rate Zones: During a workout, you can swipe up to see which zone you’re in. If those zones feel wrong (like it says you're at 100% when you're barely jogging), you need to change your birthdate or weight in the Health app on your iPhone, not the watch.
- Sleep Tracking: If the watch is too bright at night, ensure "Sleep Focus" is scheduled. You can find this in the Control Center (side button press on newer watchOS versions).
The App View: Grid vs. List
The "Honeycomb" grid of icons is pretty. It’s also a functional disaster for anyone with fingers larger than a toddler's.
To change this, go to Settings > App View. Choose List View.
Now, you can just scroll through an alphabetical list using the Digital Crown. It’s faster. It’s cleaner. It makes sense.
App-Specific Tweaks
Sometimes you want to change how a specific app behaves. Take the Music app. You can set the watch to automatically download "Heavy Rotation" playlists so you have music even without your phone. This is handled in the Watch app on iPhone > Music.
Same goes for Workouts. There’s a setting called "Auto-Pause." If you’re a runner who constantly has to stop at traffic lights, turn this on. The watch uses the accelerometer and GPS to detect when you've stopped moving and pauses the timer. It’s surprisingly accurate.
Siri and Privacy
"Hey Siri" can be annoying if it triggers every time you raise your hand to drink coffee.
Go to Settings > Siri.
You have three options:
- Listen for "Hey Siri"
- Raise to Speak
- Press Digital Crown
I personally turn off "Raise to Speak." It’s too sensitive. While you're there, check Siri History and delete it if you're worried about Apple's servers holding onto your voice snippets.
Actionable Next Steps for a Perfect Setup
If you want to truly master your device, follow this specific order of operations:

- Audit your notifications first. Go to the iPhone Watch app and disable at least 50% of the "Mirror iPhone" toggles. Your brain will thank you.
- Switch to List View. Stop hunting for tiny bubbles in the grid.
- Set up your Focus Filters. Ensure that when you are at work, your watch face automatically changes to something professional and muted, then swaps to a fitness-heavy face when you hit the gym. You do this in the iPhone Settings > Focus menu.
- Adjust the Haptic Strength. Set it to "Prominent" so you never miss a text again, even while moving.
- Update your Medical ID. It’s the most important "setting" you’ll ever fill out. Access it via the Health app on your phone.
The Apple Watch is meant to be invisible. If you’re constantly fiddling with it, it’s failing. Spend twenty minutes in these menus today, and you won't have to touch them again for a year.
