Apple has sold tens of millions of AirTags.
My buddy Dan bought four of them two years ago. He clipped one to his keys, one to his luggage, and then tossed the other two in a kitchen drawer and forgot about them.
Last month, he lost his wallet at the airport. He opened the Find My app and just stared at the screen, because he had no idea how any of it actually worked.
A guy standing next to him, a former Apple Store Genius, glanced over and said: "Bro, you're using 15% of that thing."
Over the next ten minutes, he showed Dan every setting he had never touched. Dan found his wallet in 40 seconds.
Here are 10 AirTag features and settings most owners never find, in the exact order he showed them:
A Tesla owner got his electricity bill last month.
$340.
It had been $190 the month before he bought the car.
He did the math. He drives about 1,100 miles a month. A Model 3 uses roughly 0.25 kWh per mile, so about 275 kWh.
At his normal rate, that should add around $50.
Not $150.
He called the utility. They said the meter was accurate.
He called Tesla. They said the car was working normally.
He sat at the kitchen table with the bill, convinced he was either being scammed or had a defect nobody could find.
Then his neighbor stopped by. He'd worked 9 years for a regional utility company and had driven a Tesla for 4 of them.
He looked at the bill for about 10 seconds.
"You're not being overcharged. You're charging at the worst possible time, on the worst possible plan, with 3 settings you've never touched."
"Give me 10 minutes. I'll show you."
Here are the 7 fixes that cut his bill by $127 the very next month: 🧵
Fix #7: Set the charge limit and stop guessing.
He had been charging to 100% every night "to be safe."
His neighbor changed it.
"For daily driving, set the limit to 80% or 90%. Only go to 100% before a long trip."
It won't change your bill dramatically on its own.
But it means less time at a high state of charge, which is easier on the battery long term, and it keeps the car from running long charging sessions it doesn't need.
Then he showed him the Energy tab in the app, where you can see exactly how much energy each trip used and compare it to the car's estimate.
"Your bill isn't a mystery. It's a spreadsheet. You just never looked at it."
The next month, his bill was $213.
Still above the $190 he paid before the car, but now it was $50 for 1,100 miles of driving, not $150.
He told me that's about what gas used to cost him per week.
The full list, so you can screenshot it:
1. Schedule charging for off-peak hours
2. Sign up for your utility's EV rate plan
3. Precondition while plugged in
4. Turn off Sentry and overheat protection at home
5. Use Superchargers for trips only
6. Install a 240V outlet
7. Set a daily charge limit of 80-90%
Most Tesla owners do none of these in the first year.
Your car isn't expensive to run. Your settings are.
I bought a $249 vacuum on Amazon last Friday. My brother-in-law, who sold on Amazon for 5 years, looked at the page and said: "You just bought it at the highest price of the year."
He pasted the link into a price-history tracker. A graph popped up. That vacuum had been $159 for 8 of the last 12 months. The price jumped right before the weekend, because the algorithm saw 3 people viewing it.
Then he opened my order history. 41 purchases. He found the same pattern in 29 of them. Prices rising when I was in a hurry. Dropping when I wasn't looking.
"Amazon doesn't have one price," he said. "It has the price you're willing to pay today."
I cancelled the order, waited 6 days, and rebought it for $163. I did that on 11 more items and saved $412 in one month.
Here are the 8 Amazon settings and tricks that stop you from overpaying:
8. Use a wish list to catch price drops without chasing them.
Add anything you're thinking about to a wish list instead of the cart. Amazon shows price-drop badges on list items, and the Amazon app can notify you when something on your list gets cheaper.
I keep one list called "Wait." Everything I want sits there for at least a week. I check it every Sunday night and buy only the items that dropped.
Most of the time, I forget half the stuff on that list by the next weekend. Which means I never needed it.
That alone cut my Amazon spending by about a third. Not from deals. From not buying things I wanted for 10 minutes.
The best discount is the purchase you don't make.
Recap: the 8 ways to stop overpaying on Amazon.
1. Check the price history (Keepa, CamelCamelCamel)
2. Set price alerts and wait
3. Let items sit in your cart
4. Check Amazon Warehouse
5. Open "Other sellers"
6. Tick every coupon box
7. Subscribe & Save on repeat items
8. Keep a "Wait" wish list
Amazon doesn't hide any of this. They just count on you being in a hurry.
A girl paid $1,600 for her MacBook and has only used it for Chrome and Netflix for 3 years.
Last Thursday, she was fighting to merge two PDFs. She opened a website, uploaded the files, got hit with a paywall, closed it, and tried another one. Her roommate walked by, watched for a few seconds, and quietly asked:
"Wait... you've never used any of the built-in tools?"
"What built-in tools?"
He took the laptop and started talking: "You can dictate a full email by talking. Your screen can be split into two windows in one click. You can copy text from any photo or screenshot. You can sign a document without printing it. You can find any file in 2 seconds. Your clipboard, your trackpad gestures, your shortcuts. All of it has been sitting there since day one."
She stared at the screen.
"You didn't buy a $1,600 laptop. You bought a $1,600 browser."
He spent 30 minutes changing settings and showing her shortcuts. Afterward she said: "I just got back 5 hours of my week."
Here are the 12 Mac features and settings most owners never open, in the exact order he showed her 🧵
12. Battery and storage health
The last setting was the one that protects the $1,600.
System Settings → Battery → Battery Health. It showed 91% with a recommendation to turn on Optimized Battery Charging. He switched it on. It learns your routine and holds at 80% until you need it.
Then System Settings → General → Storage. She had 74 GB of old downloads, 31 GB of duplicate files, and a Trash with 18 GB she had never emptied.
He turned on Empty Trash Automatically after 30 days and Optimize Storage. Then he deleted old installers and large files she hadn't touched in a year.
She freed up 120 GB without losing anything she cared about.
"A laptop that's maintained lasts 3 years longer," he said. "That's $1,000 you don't spend."
That was the whole 30 minutes.
She didn't buy a new Mac. She didn't download a single app. She didn't spend a dollar. She just finally opened the menus that had been there for 3 years.
Here's what she told him afterward: "I thought I bought a laptop. It turns out I bought a toolbox, and I was using it as a paperweight."
Most people never go through the settings on the things they own. They pay for the best, then use 10% of it.
If you've had your Mac for more than a year and haven't opened these 12, you're probably the girl in this story.
Take 15 minutes tonight and try 3 of them. Then send this to the friend who's still printing PDFs.
