Back to School 2026: Turn Old Devices Into New-Tech Cash

The most valuable thing in most junk drawers is last year's phone — and it's rarely the only thing in there worth money. At GadgetRenu's current rates (as of August 2026), a used iPhone 14 trades in for up to $275, an iPhone 13 up to $214, and even an iPhone 12 up to $143. Those are top-of-range figures — highest storage, Excellent condition, unlocked — so wear, smaller storage, and a carrier lock move you down. The point stands: the phone you set aside at your last upgrade still carries a real number.

iPads are the device families most often forget. Kids outgrow the small ones, screens crack, or a school changes platforms. An iPad 10th gen runs up to $206 and an iPad Air 5 up to $240 — worth a look before it lives in a drawer for another year.

MacBooks hold their value better than almost anything else here. A MacBook Air 13" M2 (2022) trades in for up to $617. If a college-bound student is retiring the laptop they used through high school, that one device is usually the biggest line item in the whole pile.

Samsung phones are worth checking too, though they slide faster than Apple hardware — a Galaxy S22 brings up to $108. Small on its own, but it adds to the pot.

*Range spans low-condition/small-storage up to Excellent, top-storage, unlocked. As of August 2026.

Treat this as a household inventory, not one phone at a time. Add up every unused device across everyone under the roof, and the total is usually higher than anyone guessed.

Take a family of four clearing out before the school year. Here's what a realistic spread of hand-me-downs looks like at the top of GadgetRenu's range:

That $1,455 is the ceiling — everything at highest storage in Excellent condition. Base storage and a few years of scuffs pull each line lower, but five common devices like these clearing several hundred dollars together is routine. That covers a Chromebook for a middle schooler, a big dent in a laptop for a college student, or first phones for the kids on hand-me-downs.

Timing decides how much of that you keep. Back-to-school shopping peaks in August — the weeks right before Apple's September announcement, which reliably drags older-model values down. As covered in our best time to sell your phone guide, selling into this window captures the most value before the fall slide. GadgetRenu's 14-day price lock lets you lock a quote now and ship when you're ready.

Selling several at once is one shipment: get a separate instant quote for each device (about two minutes each), drop them in a single box with one free insured USPS label, and each is inspected — with photos documenting its condition, so there's no bait-and-switch — and paid out on its own within three business days after delivery. GadgetRenu is a family-owned shop in Wallington, NJ.

Kids' phones and tablets carry photos, school logins, messages, and sometimes location history. Wipe them before they leave the house.

iPhones and iPads

1. Back up first. Settings > [Name] > iCloud > iCloud Backup > Back Up Now.
2. Sign out of iCloud. Settings > [Name] > Sign Out, then enter the Apple ID password. A device still tied to an iCloud account can't be resold.
3. Confirm Find My is off. It usually clears when you sign out; check under Settings > [Name] > Find My.
4. Erase all content and settings. Settings > General > Transfer or Reset > Erase All Content and Settings — a cryptographic wipe that makes the data unrecoverable.
5. Pull the SIM if there is one.

MacBooks

1. Back up with Time Machine or copy key files to a drive or the cloud.
2. Sign out of iCloud in Settings > Apple ID > Sign Out.
3. Sign out of iMessage in Messages > Settings > iMessage > Sign Out.
4. Deauthorize in Music (or iTunes) > Account > Authorizations > Deauthorize This Computer.
5. Erase and reinstall macOS from Recovery (hold Command+R on Intel, or hold the power button on Apple Silicon), wipe the drive in Disk Utility, then reinstall.

Samsung and Android

1. Back up in Settings > System > Backup.
2. Remove your Google account in Settings > Accounts.
3. Factory reset in Settings > General Management > Reset > Factory Data Reset.
4. Remove the SIM and SD card.

Our how to wipe your iPhone before selling guide walks it through with screenshots. If any of this feels like a hassle, GadgetRenu runs a Certified Data Wipe on every device it receives at its R2-certified facility, following NIST 800-88 (Purge) — so your family's data is destroyed to standard whether or not you wiped it first.

If you have kids, you have cracked screens. Broken rarely means worthless — GadgetRenu quotes damaged devices, and the payout tracks what's actually wrong.

Every model carries a range, not a single price. An iPhone 14 runs from $31 at the low end to $275 in Excellent condition; a MacBook Air M2 from $161 to $617. Damage moves you toward the bottom of that range instead of off it:

• Cracked screens lower the offer — a shattered panel with dead touch costs more than a hairline corner chip, but both still quote.
• Weak batteries shave a bit off, since a battery is a cheap, replaceable part, not a reason to scrap the device.
• Scratches, dents, and scuffs matter less than people expect; a rough-looking phone that powers on and works is still refurbishable. Bent frames and deep gouges count for more.
• Water-damaged or dead units can still hold parts-and-materials value, so they're worth a quote before the trash.

A device that powers on cleanly — unlocked, no account lock, with a healthy battery — sits higher in its range; our tips to get the most money selling your phone covers the quick wins before you ship.

The rule for families: don't bin anything without checking. The quote takes two minutes, and declining a low one costs nothing.

Since the devices going out the door are often theirs, back-to-school selling doubles as a first lesson in how gadgets lose value.

• Show them the numbers. Pull up what their phone cost new next to today's GadgetRenu quote, then what it's likely to bring after September. Depreciation stops being abstract when it's their iPhone on the screen.
• Give them a cut. Letting a teen keep 25 to 50 percent of their old phone's payout turns "don't drop it" into a rule they actually have a stake in.
• Let them run it. Have them get the quote, pack the box, print the label, and watch the payment land. It's a real transaction from start to finish, and it demystifies buying used later.

There's an environmental thread here worth mentioning without a lecture. The UN's Global E-waste Monitor 2024 found the world generated 62 million tonnes of e-waste in 2022, and only about 22 percent was formally collected for recycling. Selling a working device for reuse keeps it out of that pile. Devices GadgetRenu receives are evaluated for refurbishment first; anything at end-of-life is handled through its R2-certified facility for responsible recycling.

Can I sell several devices at once?

Yes, with no limit. Get a separate quote for each, ship them together in one box on a single free insured USPS label, and each is inspected and paid out individually within three business days after delivery. Families routinely send 3 to 5 at a time in the summer.

How old is too old to sell?

Older than you'd think. iPhones back to the iPhone 12 (up to $143) and iPads back to the 8th generation (up to $71) still draw offers, and even devices past that can carry parts value. The quote takes about two minutes, so there's little reason not to check on the iPhone or iPad page.

What if my kid's phone has a cracked screen?

A crack lowers the offer but doesn't zero it. Each model has a published range, and damage moves you toward the low end rather than off the list — an iPhone 14, for example, still quotes somewhere between its $31 floor and $275 ceiling depending on condition. Photos from the inspection document the actual condition, so there's no surprise lowball. Send it in and see the number.

Is my family's data safe?

Every device gets that same Certified Data Wipe to NIST 800-88 (Purge) at GadgetRenu's R2-certified facility, so your photos, messages, and accounts are destroyed even if you forget to wipe it first. Doing it yourself with the steps above is still the recommended first step.

When should I sell?

Right now, in August — before Apple's September announcement starts the depreciation cycle, and while there's still cash-in-hand time before the school year begins. The 14-day price lock lets you secure a quote early and ship within the window. See what everything's worth on the main selling page.
