I Use These 7 Apple Watch Features Every Day to Improve Performance

I wouldn’t go anywhere without my Apple Watch, and these are some of the reasons why.

If you’re athletic, the Apple Watch can help you boost your body’s performance, whether that’s staying on top of your pace and heart rate during a run or tracking your sleep cycles. But workouts aren’t the only things that benefit from an Apple Watch. It also helps me stay on top of my schedule and is clutch in the kitchen when I need multiple timers. It’s these types of little details that make everyday tasks just that much easier.

And that’s just the beginning: At Apple’s Worldwide Developer Conference the company announced WatchOS 26, which will bring the new Liquid Glass design to the watch as well as the intriguing AI-based Workout Buddy feature. Here’s everything you missed at WWDC 2025.

Before WatchOS 26 arrives this fall, however, here are some of my favorite Apple Watch in WatchOS 11.

Swipe between watch faces (again)

Until WatchOS 10.0, you could swipe from the left or right edge of the screen to switch active watch faces, a great way to quickly go from an elegant workday face to an exercise-focused one, for example. Apple removed that feature, likely because people were accidentally switching faces by brushing the edges of the screen.

However, the regular method involves more steps (touch and hold the face, swipe to change, tap to confirm) and people realized that the occasional surprise watch face change wasn’t really so bad. Therefore, as of version 10.2, including the current WatchOS 11.2, you can turn the feature on by toggling a setting: Go to Settings > Clock and turn on Swipe to Switch Watch Face.

Stay on top of your heart health with Vitals

Wearing your Apple Watch while sleeping offers a trove of information — and not just about how you slept last night. If you don the timepiece overnight, it tracks a number of health metrics. A new feature in WatchOS 11 gathers that data into the Vitals app that reports on the previous night’s heart rate, respiration, body temperature (on recent models) and sleep duration. The Vitals app can also show data collected during the previous seven days — tap the small calendar icon in the top-left corner.

(If you own a watch model sold before Jan. 29, 2024, you’ll also see a blood oxygen reading. On newer watches in the US, that feature is disabled due to an intellectual property infringement fight.)

How is this helpful? The software builds a baseline of what’s normal for you. When the values stray outside normal ranges, such as irregular heart or respiratory rates, the Vitals app reports them as atypical to alert you. It’s not a medical diagnosis, but it can prompt you to get checked out and catch any troubles early.

Make the Smart Stack work for you

The Smart Stack is a place to access quick information that might not fit into what Apple calls a «complication» (the things on the watch face other than the time itself, such as your Activity rings or the current outside temperature). When viewing the clock face, turn the digital crown clockwise or swipe from the bottom of the screen to view a series of tiles that show information such as the weather or suggested photo memories. This turns out to be a great spot for accessing features when you’re using a minimal watch face that has no complications.

Choose which Live Activities appear automatically

The Smart Stack is also where Live Activities appear: If you order a food delivery, for example, the status of the order appears as a tile in the Smart Stack (and on the iPhone lock screen). And because it’s a timely activity, the Smart Stack becomes the main view instead of the watch face.

Some people find that too intrusive. To disable it, on your watch open the Settings app, go to Smart Stack > Live Activities and turn off the Auto-Launch Live Activities option. You can also turn off Allow Live Activities in the same screen if you don’t want them disrupting your watch experience.

Apple’s apps that use Live Activities are listed there if you want to configure the setting per app, such as making active timers appear but not media apps such as Music. For third-party apps, open the Watch app on your iPhone, tap Smart Stack and find the settings there.

Add and pin favorite widgets in the Smart Stack

When the Smart Stack first appeared, its usefulness seemed hit or miss. In WatchOS 11, Apple seems to have improved the algorithms that determine which widgets appear — instead of it being an annoyance, I find it does a good job of showing me information in context. But you can also pin widgets that will show up every time you open the stack.

For example, I use 10-minute timers for a range of things. Instead of opening the Timers app (via the App list or a complication), I added a single 10-minute timer to the Smart Stack. Here’s how:

View the Smart Stack by turning the Digital Crown or swiping from the bottom of the screen.
Touch and hold the screen to enter the edit mode.
Tap the + button and scroll to the app you want to include (Timers, in this example).
Tap a tile to add it to the stack; for Timers, there’s a Set Timer 10 minutes option.
If you want it to appear higher or lower in the stack order, drag it up or down.
Tap the checkmark button to accept the change.

The widget appears in the stack, but it may get pushed down in favor of other widgets the watch thinks should have priority. In that case, you can pin it to the top of the list: While editing, tap the yellow Pin button. That moves it up, but Live Activities can still take precedence.

Use the watch as a flashlight

You’ve probably used the flashlight feature of your phone dozens of times, but did you know the Apple Watch can also be a flashlight? Instead of a dedicated LED (which phones also use as a camera flash), the watch’s full screen becomes the light emitter. It’s not as bright as the iPhone’s, nor can you adjust the beam width, but it’s perfectly adequate for moving around in the dark when you don’t want to disturb someone sleeping.

To activate the flashlight, press the side button to view Control Center and then tap the Flashlight button. That makes the entire screen white — turn the Digital Crown to adjust the brightness. It even starts dimmed for a couple of seconds to give you a chance to direct the light away so it doesn’t fry your eyes.

The flashlight also has two other modes: Swipe left to make the white screen flash on a regular cadence or swipe again to make the screen bright red. The flashing version can be especially helpful when you’re walking or running at night to make yourself more visible to vehicles.

Press the Digital Crown to turn off the Flashlight and return to the clock face.

Pause your Exercise rings if you’re traveling or ill

Closing your exercise, movement and standing rings can be great motivation for being more active. Sometimes, though, your body has other plans. Until WatchOS 11, if you became ill or needed to be on a long-haul trip, any streak of closing those rings that you built up would be dashed.

Now, the watch is more forgiving (and practical), letting you pause your rings without disrupting the streak. Open the Activity app and tap the Weekly Summary button in the top-left corner. Scroll all the way to the bottom (take a moment to admire your progress) and tap the Pause Rings button. You can choose to pause them for today, until next week or month, or set a custom number of days.

When you’re ready to get back into your activities, go to the same location and tap Resume Rings.

Bypass the countdown to start a workout

Many workouts start with a three-second countdown to prep you to be ready to go. That’s fine and all, but usually when I’m doing an Outdoor Walk workout, for example, my feet are already on the move.

Instead of losing those steps, tap the countdown once to bypass it and get right to the calorie burn.

How to force-quit an app (and why you’d want to)

Don’t forget, the Apple Watch is a small computer on your wrist, and every computer will have glitches. Every once in a while, for instance, an app may freeze or behave erratically.

On a Mac or iPhone, it’s easy to force a recalcitrant app to quit and restart, but it’s not as apparent on the Apple Watch. Here’s how:

Double-press the Digital Crown to bring up the list of recent apps.
Scroll to the one you want to quit by turning the crown or dragging with your finger.
Swipe left on the app until you see a large red X button.
Tap the X button to force-quit the app.

Keep in mind this is only for times when an app has actually crashed — as on the iPhone, there’s no benefit to manually quitting apps.

These are some of my favorite Apple Watch tips, but of course there’s a lot more to the popular smartwatch. Be sure to also check out which new health features are expected in the next models and Lexy Savvides’ review of the Series 10.

Kohler Wants to Put a Tiny Camera in Your Toilet and Analyze the Contents

The company’s new Dekoda toilet accessory is like a little bathroom detective.

Some smart litter boxes can monitor our pets’ habits and health, so having a camera in our human toilet bowls seems inevitable. That’s just what kitchen and bathroom fixture company Kohler has done for its new health and wellness brand, Kohler Health.

The $599 Dekoda clamps over the rim like a toilet bowl cleaner, pointing an optical sensor at your excretions and secretions. It then analyzes the images to detect any blood and reviews your gut health and hydration status. Depending on the plan you choose, the subscription fee is between $70 and $156 per year.

At toilet time, you sign in via a fingerprint sensor so that the device knows who’s using the facilities. (Please wash your hands before signing out or tracking your progress.) Then, check in with the app for the day’s analysis and trends over time.

Wait until you’re off the pot, though, before you start doomscrolling your health. The device has a removable, rechargeable battery and uses a USB connection.

Kohler says it secures your data via the aforementioned fingerprint scanner and end-to-end encryption, and notes that the camera uses «discreet optics,» looking only at the results, not your body parts.

«Dekoda’s sensors see down into your toilet and nowhere else,» the company says.

Kohler warns that the technology doesn’t work very well with dark toilet colors, which makes sense. I’m sure there could be an upsell model with a light on it. Maybe the company could add an olfactory sensor, since smell reveals a lot about your gut health too. It could track «session» length or buildup under the rim to alert whoever has responsibility to clean it.

Kohler must have been straining to find appropriate lifestyle photos to include with the publicity materials. Many of the images are hilarious, featuring fit-looking men and women drinking water and staring off into space contemplatively — probably thinking about gas.

Does Charging Your Phone Overnight Damage the Battery? We Asked the Experts

Modern smartphones are protected against overcharging, but heat and use habits can still degrade your battery over time.

Plugging your phone in before you head to bed might seem like second nature. That way by the time your alarms go off in the morning, your phone has a full charge and is ready to help you conquer your day. However, over time, your battery will start to degrade. So is keeping your phone plugged in overnight doing damage to the battery?

The short answer is no. Keeping your phone plugged in all the time won’t ruin your battery. Modern smartphones are built with smart charging systems that cut off or taper power once they’re full, preventing the kind of «overcharging damage» that was common in older devices. So if you’re leaving your iPhone or Android on the charger overnight, you can relax.

That said, «won’t ruin your battery» doesn’t mean it has no effect. Batteries naturally degrade with age and use, and how you charge plays a role in how fast that happens. Keeping a phone perpetually at 100% can add extra stress on the battery, especially when paired with heat, which is the real enemy of longevity.

Understanding when this matters (and when it doesn’t) can help you make small changes to extend your phone’s lifespan.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.
