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 guy paid $1,999 for the iPhone Duo and skipped AppleCare+ to save a few bucks.
Six hours later, he was showing it to a friend. He opened it, felt something under the screen near the hinge, heard a crack, and watched a bright line split the inner display. Nothing had hit it. Nothing had been dropped.
He called his brother, a former Apple Store specialist, who pulled up Apple's repair prices and read the number out loud.
"Without coverage, a new inner display costs about half the price of the phone. $999."
"But it was brand new."
"That's why nobody tells you to check the coverage before you open the box."
That night they spent 20 minutes fixing 6 things. The 7th waited until the next day.
Here are the 7 things to do in the first 48 hours with any new foldable phone: 🧵
7. Do a 60-second check every day for the first week
This was the one he did the next morning.
Turn the inner display to solid white, then solid black. Look for lines, dead pixels, flicker, discoloration, or an uneven crease. Fold and unfold it 3 times, slowly, and listen. Check the outer display too.
If you find anything, photograph it with the date and go to the store right away. Early reports show problems appearing within hours or days, so the first week is when a problem is easiest to prove and easiest to get replaced.
His brother said: "If you wait three months, it's your word against the phone. If you catch it in three days, it's a clean claim."
Sixty seconds a day for 7 days. That's all.
That was the whole 48 hours.
He didn't need a new case, a new app, or a new phone. He needed a checklist and 20 minutes. If he'd done it before opening the box, he would have bought the coverage, filmed the unboxing, and had a record of a clean screen.
Here's what he told his brother afterward: "I spent two hours reading reviews before I bought it, and zero minutes reading the repair prices."
Most people check coverage after something breaks. By then, it's too late to be smart about it.
If you've bought a foldable, or any $1,000+ phone, run through these 7 tonight. Then send this to the friend who just bought one.

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.
