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.

How Did ChatGPT Get ‘Absolutely Wrecked’ at Chess by an 1970s-Era Atari 2600?
The console Gen Xers used to play Pac-Man and Pitfall on apparently was better than anyone knew.
OpenAI’s ChatGPT has some major AI chatbot competitors in the market: Gemini, Copilot, Claude. Now add to that list the Atari 2600. The OG video game console, which was first released in 1977, was used in an engineer’s experiment to see how it would fare playing chess against the AI chatbot.
By using a software emulator to run Atari’s 1979 game Video Chess, Citrix engineer Robert Caruso said he was able to set up a match between ChatGPT and the 46-year-old game. The matchup did not go well for ChatGPT.
«ChatGPT confused rooks for bishops, missed pawn forks and repeatedly lost track of where pieces were — first blaming the Atari icons as too abstract, then faring no better even after switching to standard chess notations,» Caruso wrote in a LinkedIn post.
«It made enough blunders to get laughed out of a 3rd-grade chess club,» Caruso said. «ChatGPT got absolutely wrecked at the beginner level.»
Caruso wrote that the 90-minute match continued badly and that the AI chatbot repeatedly requested that the match start over.
For decades, the ability for computers to defeat humans at chess has been a measure of their power. In 1997, IBM made headlines when its Deep Blue technology defeated chess grandmaster Garry Kasparov in a series of matches.
Caruso’s experiment doesn’t mean ChatGPT is useless for chess, but because it’s more of a language model than a supercomputer, it’s less likely to serve that purpose well. A few years ago, a developer created a ChatGPT plugin called ChessGPT. But it may be better to discuss chess with OpenAI’s chatbot than to try to play against it.
A representative for OpenAI did not immediately return a request for comment.
(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Your 2018 iPhone XS Is Now a ‘Vintage’ Device: Here’s What That Means
The device will still get updates for the rest of the year, but Apple is otherwise ceasing support for the 2018 iPhone.
Things don’t last forever, and in the tech world, they rarely even last five years. Apple lists older products on what it calls the vintage list, which consists of products the company stopped selling five to seven years ago. And if you bought your iPhone in 2018, the iPhone XS, your phone is now officially vintage.
The iPhone XS launched in 2018 and was officially discontinued in 2020 once all of its stock ran out. The phone joins the iPhone 7 Plus, two iPhone 8 models, the iPhone XS Max, and the iPhone 6S Plus, all of which have been added to the list since the calendar flipped to 2025.
Now that it’s there, the iPhone XS, along with the other iPhones listed above, will spend the next two years as a vintage device on Apple’s roster. Once they hit the seven-year mark, these phones will be moved to the obsolete list. The most recent device to be rendered obsolete by Apple is the 5th-generation iPad.
You have a vintage phone, so what now?
The good news is that having a vintage phone doesn’t mean much in the immediate short term, but it will before the end of the year.
Apple products continue to have repair support for up to five years after they leave store shelves, but can still be repaired after the five-year mark, provided that there are still parts available. That means that the iPhone XS and the other models listed are no longer officially supported, but repair techs can still order parts as long as Apple has them.
Such parts are likely in abundance since the phone just entered the vintage list. However, over the next two years, it’ll become harder and harder for repair shops to find official parts for the iPhone XS. So, if your phone breaks next year, there is no guarantee that a repair shop will be able to find official parts to fix it.
In terms of software, it’s much the same story. Apple is still releasing iOS 18 updates and will continue to do so until iOS 26 comes out. After that, Apple tends to stop supporting the prior generation of iOS. Since the iPhone XS is not included on the list of iOS 26-compatible devices, software support will mostly end later this year once the new version comes out.
Apple did this last year as well, with the final iOS 17 update releasing on Nov. 19, 2024. Apple typically guarantees support for devices for up to five years, and since the iPhone XS came out in 2018, it has long since surpassed the mark.
Being put on the vintage list can be construed as a light warning from Apple that your phone will no longer be supported very soon. If you own an iPhone XS, you’ll have software support until November when iOS 26 launches, and you’ll have repair support as long as the parts hold out. You don’t need a new phone today, but it’s something you may want to look into sooner rather than later.

iPhone 17 Rumors: New iPhone Battery Could Be Stronger and Smaller
Speculation on better battery life and charging could give a power boost to the rumored iPhone Air.
The next iteration of iPhones is just around the corner, with an official announcement expected sometime this fall. With the Worldwide Developers Conference now behind us, we’re most looking forward to the announcement of the iPhone 17.
There are plenty of rumors about what the next iPhone will look like and what sort of specs it may have. One of the more popular talking points for any new smartphone release is battery life, and the new iPhone is no exception. A rumored iPhone 17 Air with a thinner design has raised the question of whether a slimmer iPhone would have to sacrifice battery life.
Regardless of the model type, battery life is a concern across the board. After all, you can’t use your new tech if the battery drains too fast and doesn’t last more than a few hours. We’ve sorted through all the rumors and leaks when it comes to the battery for the iPhone 17. Let’s break it down.
Battery size for the next iPhone
Current iPhones utilize a lithium-ion battery, which is less malleable and not really conducive to being used in a slimmer model, like the rumored iPhone 17 Air. So, if they were to shrink the lithium-ion battery to fit a skinnier frame, it would likely have less capacity. However, Apple may be adding a silicon-anode battery to the new slimmer iPhone, according to AppleInsider.
Compared with graphite-based anodes, common in lithium-ion batteries, silicon anodes can hold more lithium ions, allowing them to store more energy. In theory, that would mean a more compact silicon-anode battery wouldn’t sacrifice power. The iPhone may even charge faster than previous iterations as a result. As for the rumored iPhone 17 Pro Max, according to 9to5mac, it’s expected to have a slightly larger battery than the iPhone 16 Max Pro.
AI-powered battery management
The next iPhones (and the current models after iOS 26 rolls out) will have AI-powered adaptive battery energy management starting this fall, we learned at WWDC. Part of Apple Intelligence, the company will utilize AI to monitor how you use your device and adjust performance and energy consumption settings accordingly, aiming to extend the phone’s battery life. Think of Adaptive Power as the first step toward extending your iPhone’s battery life and Low Power mode as the last step of doing the same.
Another piece of new hardware that’ll likely impact battery efficiency is the rumored A19 processing chip. The iPhone 17 base and Air will likely get the A18 chip, which is the same chip that the iPhone 16 uses. However, according to Apple analyst Jeff Pu, the rumored iPhone 17 Pro and iPhone 17 Pro Max are set to include the A19 chip, which would likely come equipped with better optimization, which in turn could impact how long the battery will last on the rumored iPhone, and how efficiently it will run.
How accurate are iPhone rumors?
Until Apple officially releases its new phone, speculation on the iPhone 17 is simply educated guesswork. While most rumors come from insider knowledge or are leaked from the teams working on these products, until Apple says otherwise, they remain rumors.
