@details_with_ai Adaptive Audio is one of those features that deserves way more attention.

Apple has sold over 600 million AirPods.

Most people use them for 3 things: Music. Podcasts. Phone calls.

That's a pair of $249 earbuds doing the job of a $30 pair from 2015.

A former Apple Genius Bar technician who spent 4 years behind the counter told me: "I've had thousands of people tell me their AirPods 'just work.' They do. That's the problem. They work exactly as shipped. The settings that make them sound better, fit better, and do more are buried in menus most people never open."

He said the gap between how people use AirPods Pro and what they can actually do is the same as the gap between a stock car and a tuned one.

Here are the 8 AirPods Pro settings that change how they work: 🧵

A guy bought a $1,800 Samsung TV 2 years ago.

He watches Netflix. He watches YouTube. He watches the game on Sundays. He thought that was everything a TV does.

His friend a home theater installer who's set up over 500 Samsung TVs came over, picked up the Siri Remote, and stopped himself. "Wait you're not even using the Samsung remote's full features. And you've got a $1,800 computer on your wall that you're running 2 apps on."

"Your Samsung TV is a gaming console you've never loaded a game on. It's a smart home hub you've never connected a device to. It's a second screen that can run two inputs simultaneously. It has 200+ free TV channels you've never opened. It has a built-in art gallery that turns it into a framed painting when you're not watching. It has a sound system that tracks objects across the screen. And the picture you've been watching for 2 years is set to showroom mode the worst possible configuration for your living room."

"Samsung TVs are the most feature-rich televisions on the planet. Most owners use about 15% of what's inside. The other 85% is sitting behind menus, apps, and settings that nobody told them existed."

Here are 11 Samsung TV features most owners have never set up:

A productivity consultant told her audience something that reframes how every iPhone owner should think about one menu in Settings they've never opened.

"Apple builds some of its most powerful iPhone features and puts them in the Accessibility menu. Then Apple labels the menu 'Accessibility' a word most people associate with disability accommodations, hearing aids, and screen readers. The result: 95% of iPhone owners never open the menu because they assume it doesn't apply to them. They scroll past it in Settings on the way to Wallpaper or Display & Brightness. They've been scrolling past it for years."

She told them the Accessibility menu on the iPhone 18 Pro Max contains features that have nothing to do with disability or rather, features designed for accessibility that solve everyday problems every iPhone owner faces. Sound Recognition that hears the doorbell while the owner wears noise-canceling headphones. Live Captions that transcribe any audio on the phone in real time calls, videos, podcasts without an internet connection. Voice Control that operates the entire phone hands-free without Siri. Guided Access that locks the phone into one app so the toddler playing a game can't accidentally open email, delete photos, or call the boss. LED Flash for Alerts that makes the camera flash blink for notifications for the user whose phone is on silent and face-down.

Each feature was designed for users with specific accessibility needs. Each feature solves a problem every iPhone owner has. Each feature is buried in a menu 95% of owners have never tapped because the name says "Accessibility" and the owner says "that's not for me."

She showed her audience 11 Accessibility features that belong in every iPhone owner's daily workflow not because of disability, but because of capability.

Here's every power tool hiding in the wrong menu 🧵

A guy with mild hearing loss told his audiologist he couldn't follow dialogue in movies. Explosions were deafening. Whispered conversations were inaudible.

His audiologist said: "Do you have an Apple TV?"

He did.

She told him to go to Settings → Video and Audio → Enhance Dialogue. One toggle. It uses computational audio to isolate human voices from background noise and boost them — in real time — without changing the volume of anything else.

He turned it on. For the first time in years, he heard every word.

That feature has been buried in his Apple TV since the day he bought it. He'd been ready to spend $3,000 on a soundbar with dialogue enhancement. The Apple TV did it for free.

Here are 11 features most Apple TV owners have never found 🧵

Netflix's #1 customer complaint worldwide isn't buffering. Isn't price. Isn't content.

It's: "I can't find anything to watch."

260 million subscribers. The most common sentence across all of them: "There's nothing on Netflix." While sitting in front of a library of 17,000+ titles.

A guy who handled 15,000 Netflix support tickets in 3 years told me why:

"It's not that there's nothing to watch. It's that Netflix is hiding everything worth watching behind 10 settings you never changed."

"Your streaming quality is set to Auto. You're watching 4K content in 720p and blaming your TV."

"Your autoplay previews are on. Every thumbnail you pause on for 2 seconds feeds false data to the algorithm. Your homepage is built on accidents."

"Your profile is shared with 3 people. The algorithm thinks you're one person who loves true crime, kids' shows, and Korean dramas at the same time."

"Your viewing history is full of 3 years of junk data. Shows someone else watched. Shows you fell asleep during. Shows you hate-watched. The algorithm treats all of it as your taste."

"You're not watching Netflix. You're watching a broken version of Netflix that's been getting worse every day for 3 years because nobody told you the settings existed."

"17,000 titles. You're seeing 40. Fix 10 settings and the other 16,960 appear."

Here are 10 Netflix settings most subscribers have never changed:

8.The takeaway
Deleting a photo removes the original file from its normal location.

But operating systems and applications can create additional copies, previews, indexes, or backups.

If privacy matters, don’t just delete the file—review caches, cloud storage, backups, and other copies too.

Save this thread for later. 🔖

7.There can be other traces too
Depending on your Windows setup and apps, information about files may also exist in places such as:

• Recycle Bin
• Recent-file history
• Application caches
• Cloud-sync services
• Backup systems

The exact traces depend on how the file was created, opened, synced, and deleted.

@jackcoder0 This is a fantastic breakdown of how much value Costco offers beyond the obvious. It's a great reminder to explore all their services.

A Costco member bought tires at the Costco Tire Center 4 years ago.

He's been paying $15–$25 per tire rotation at a local shop every 6 months since $120–$200 over 4 years in rotation fees alone. He didn't know Costco provides free tire rotations, free flat repairs, free tire balancing, and free nitrogen inflation for the life of any tire purchased at the Costco Tire Center. The service he's been paying a third-party shop to perform is included free forever on the tires sitting on his car right now.

His wife ordered a custom half-sheet cake from a local bakery for their daughter's birthday. $85. Custom design. Feeds 48 people. The same cake custom decorated, half-sheet, feeds 48 ordered through the Costco bakery costs $22.99. Same size. Comparable decoration. $62 less. From the bakery section she walks past every week on her way to the rotisserie chicken.

His neighbor bought a new car last month and spent 3 hours negotiating at the dealership. Costco Auto Program provides pre-negotiated pricing through participating dealerships the member walks in with a Costco Auto Program certificate and pays a pre-arranged price. No haggling. No back-and-forth. No "let me talk to my manager." The 3-hour negotiation replaced by a printout and a handshake.

Three members. Three services. Three savings $200 in tire fees, $62 on a cake, and potentially $1,000–$3,000 on a car forfeited because nobody told them the tire center includes lifetime service, the bakery does custom cakes for $23, and the auto program negotiates car prices before the member arrives at the dealership.

Here's every hidden Costco service most members walk past every week 🧵

Space Bunny reads images and codes like it has somewhere to be.

Gave it a napkin with a messy app idea → it read every word and doodle, then built a working hydration tracker app

️Screenshotted the running app → it reviewed the UI and improved it without being told what was wrong

Asked for a full-stack upgrade → Express server, SQLite database, REST API with 8 routes. 16 minutes.

Napkin to full-stack. One session.

Apple just released iOS 27. You updated your iPhone. You saw the new Siri. You noticed the glass looks different. You went back to scrolling.

That's 5% of the update.
The other 95% the features Apple buried in the Settings menu, hid behind gestures, and mentioned on a single slide for 3 seconds during a 90-minute keynote is sitting on your iPhone right now. Untouched.

A former Apple software engineer who spent 5 years working on iOS told me:

"Every iOS release has 2 layers. The keynote layer 8–10 features Apple markets with a demo, a slogan, and a press release. And the settings layer 30–50 features Apple buries in menus that 95% of users will never open. The settings layer is where the real upgrades live. The keynote layer is where the marketing budget goes."

"iOS 27 has a Siri that actually understands context and can control your apps. Everyone knows. iOS 27 also has independent alarm volumes something users have begged for since 2007. Nobody knows. Because Apple spent 20 minutes on Siri and 0 seconds on alarm volumes."

"iOS 27 has AI photo editing that extends images beyond their edges. Everyone saw the demo. iOS 27 also lets you extract a single high-resolution frame from any video and save it as a photo. Nobody knows. Because one got a stage demo and the other got a line on a slide."

"Every single year the features that change your daily experience the most are the features Apple talks about the least."

Here are 12 iOS 27 features Apple buried that actually change how you use your iPhone every day:

A father bought his daughter a MacBook Air M5 for college. $1,299.

The M5 chip 10-core CPU, up to 10-core GPU, 16-core Neural Engine. 16GB of unified memory. 512GB SSD. Wi-Fi 7. 18-hour battery life. The most powerful MacBook Air ever made. He bought the best because she deserved the best.

She uses it for Google Docs, Spotify, iMessage, Instagram on Safari, Netflix, Zoom lectures, and note-taking in Apple Notes.

Seven tasks. None of them requires more than 10% of the M5's processing capability. She could perform all 7 identically same speed, same smoothness, same experience on the MacBook Neo at $699. The laptop her father dismissed as "not good enough for college" without checking what it actually does.

$600 spent on a performance delta she will never perceive. $600 that could have covered 3 months of textbooks. $600 sitting inside a processor that idles at 5% utilization during 95% of her computing day.

His coworker an IT director who equips 200+ employees with laptops and decides between these exact 2 machines every quarter told him something that reframes the MacBook decision most families get wrong.

"I deploy the cheapest laptop that handles the workflow. Your daughter writes documents and browses the web. The $699 Neo handles documents and browsing. The $1,299 Air handles documents, browsing, and video rendering. Your daughter doesn't render video. The $600 you spent is insurance against a workflow she doesn't have."

He showed him the honest comparison between the 2 MacBooks Apple launched in 2026 and the framework that determines which $600 is saved and which $600 is wasted.

Here's the full breakdown 🧵
