A 2023 Consumer Reports investigation found that roughly 30 percent of iPhones listed for resale are activation-locked and essentially worthless to the buyer. The seller had no idea. That is not bad luck. That is a business model.
And it is spreading far beyond iPhones. Manufacturers across the electronics industry have spent the last decade quietly engineering their products so that resale becomes complicated, devalued, or outright impossible. They never announce this. Nobody puts it on a billboard. But the next time you try to sell your two-year-old laptop or trade in your phone, you will feel it in the number you are offered.
Think of it this way: imagine buying a used car and discovering the dealer can remotely brick the ignition if you did not buy it from them directly. You would call that extortion. In consumer electronics, they call it a “security feature.”
Here is what is actually happening, and what it costs you.
1. Activation Lock Turns Resale Phones Into Expensive Bricks
Marcus, a 34-year-old teacher from Columbus, Ohio, paid $340 for a used iPhone 13 on Facebook Marketplace in early 2024. The phone arrived, activated, and looked perfect. Two days later it asked for the previous owner’s Apple ID. The seller stopped responding. Apple support told him there was nothing they could do. Marcus is now $340 lighter and owns a very sleek paperweight.
This is not an edge case. That 30 percent figure from Consumer Reports represents hundreds of thousands of devices circulating in the resale market right now. The lock exists for legitimate anti-theft reasons. But Apple controls the unlock process entirely, and their policy makes it nearly impossible to resolve without the original owner’s cooperation. Convenient, right?
Warning: Before buying any used iPhone, go to checkcoverage.apple.com and verify the activation lock status before you send a single dollar. It takes 90 seconds and costs nothing.
2. Parts Pairing Makes Your Repair History Invisible to Buyers
Apple, Samsung, and Google have all implemented “parts pairing,” a system where replacement components are cryptographically married to a specific device’s serial number. Swap out a screen or a battery from a non-OEM source and the phone flags it in software, sometimes disabling features like Face ID or accurate battery readings. Even if the repair is technically perfect, the phone now carries a software scarlet letter.
When did you last check whether a used device you bought had third-party repairs that were quietly degrading its performance? Most buyers never find out until something stops working. The FTC’s 2021 right-to-repair report estimated that repair restrictions cost U.S. consumers between $5 billion and $10 billion annually in inflated repair costs and accelerated replacement cycles. Parts pairing is a direct contributor to that number.
Did You Know: iFixit’s 2022 analysis found that parts pairing can reduce a device’s resale value by 15 to 30 percent even when the repair itself was functionally flawless. The hardware works. The software penalizes it anyway.
3. Software Update Cutoffs Create Artificial Expiration Dates
Apple typically supports iPhones for six years. Google supports Pixels for five. Samsung has pushed flagship support to seven years starting with the Galaxy S24 series. Those numbers sound generous until you realize that “support” and “usable for resale” are not the same thing. Once a phone drops off the security update schedule, it becomes a liability for any buyer who uses it for banking, email, or anything sensitive.
This is the quieter version of the same strategy. The phone still works. The camera still shoots great photos. But the manufacturer has decided it is no longer worth updating, and the resale market knows it. Ask yourself why they do not advertise the end-of-support date on the spec sheet when you are buying. They advertise the processor speed, the camera megapixels, the water resistance rating. The expiration date is buried.
4. Trade-In Programs Are Designed to Undervalue Your Device
Carrier and manufacturer trade-in programs have one job: buy your device for as little as possible and resell it or refurbish it for as much as possible. A 2022 Counterpoint Research analysis found that trade-in values offered by carriers averaged 40 to 60 percent below open-market resale prices for the same devices in equivalent condition. That gap is not accidental. The ecosystem is designed so that going directly to a carrier feels like the safe, easy choice, while selling privately feels complicated and risky.
The activation lock problem in point one is part of what makes private resale feel risky. See how that works? The risk they created has a solution they profit from.
This connects directly to something we covered in The $2,000 Repair Trap: What Manufacturers Hide. The trade-in discount and the repair markup are two ends of the same strategy: capture value on both sides of the ownership cycle.
5. Serialized Components Block Legitimate Refurbishers
Independent refurbishers are the backbone of the affordable used-device market. They buy bulk lots of returned or damaged devices, repair them, and resell them at prices that make smartphones accessible to buyers who cannot afford new. Parts pairing and serialization are systematically dismantling that market.
Louis Rossmann, a repair advocate and technician who has testified before multiple state legislatures on right-to-repair, held up a MacBook logic board during his 2022 New York State Assembly testimony and explained in plain terms how Apple’s software intentionally disables third-party components regardless of their quality. The legislators in the room had not known. Most consumers still do not.
In 2023, Apple agreed to a $113 million settlement related to “batterygate,” in which software updates were found to have throttled older iPhones in ways that were not disclosed to consumers. That settlement covered one specific practice. The broader architecture of serialization and parts pairing remains entirely intact and entirely legal.
Pro Tip: If you are buying refurbished, ask the seller specifically whether the device has any parts-paired components and whether any features have been disabled as a result. A legitimate refurbisher will know the answer and tell you straight.
6. The Secondary Market Is Shrinking, and Prices Are Not Dropping
Here is the counterintuitive result of all of this: the used phone market is not getting cheaper. The CTIA reported that Americans held onto their smartphones for an average of 3.6 years in 2023, up from 2.9 years in 2019. Longer hold cycles mean fewer devices entering the secondary market. Fewer devices in supply, combined with growing demand from buyers who cannot afford new flagship prices, is actually pushing used phone prices up. Just like we are seeing in secondhand retail, covered in detail in Why Your Goodwill Now Charges Designer Prices, scarcity manufactured at the top of the market ripples down through every resale channel.
If you planned to offset your next upgrade by selling your current phone, that math is getting harder, not easier. The trade-in value is suppressed by manufacturer programs. The private sale market is riskier because of activation locks. And the pool of buyers who trust the secondhand market is shrinking because too many of them have had a Marcus experience.
Did You Know: According to the CTIA, Americans traded in or resold approximately 151 million devices in 2022. Analysts at Counterpoint Research project that volume could decline by up to 20 percent by 2027 if parts pairing and serialization policies continue to expand across manufacturers.
7. Regulations Are Moving, But Slowly
Minnesota passed a right-to-repair law in 2023. California followed. The EU has mandated repairability scores on electronics sold in member states starting in 2026. These are real wins. But manufacturer lobbying has successfully narrowed most of these laws to exclude the software-level serialization that does the most damage to resale markets. A law that says you can repair a screen means very little if the software still flags the repair and degrades the device.
The generation that is most exposed to this is the same one that makes the most decisions based on financial realities, not brand loyalty. If you are the kind of person who plans major purchases the way some people plan financial agreements before major commitments, as covered in Why Gen Z and Millennials Sign Prenups Before Moving In, then building resale value into your device decision from day one is exactly the kind of clear-eyed thinking this moment requires.
Your Next 3 Steps
Step 1: Before you buy any used phone this week, go to checkcoverage.apple.com for iPhones or run the IMEI through your carrier’s checker for Android devices. Verify activation lock status before any money changes hands. This single check eliminates the most expensive mistake buyers make.
Step 2: Pull up your current phone’s software information in Settings right now and look at the last security patch date. If it is more than six months behind the current date, list every app on that phone that touches your finances or your identity. Those accounts need to move to a patched device or get two-factor authentication locked down immediately, because a phone without security patches is an open door.
Step 3: Before you list your current device for sale, factory reset it, sign out of your Apple ID or Google account completely, and confirm the device no longer appears in Find My or Find My Device. Then cross-reference your asking price against both Swappa’s price checker and eBay’s completed sold listings on the same day. The average gap between what sellers ask and what buyers actually pay on eBay is where your negotiation leverage lives.
You do not have to play by the rules manufacturers wrote for this market. But you do have to know what those rules actually are.
