Best Time to Sell Your Phone in 2026: A Month-by-Month Guide

A used phone is worth the most right before its replacement shows up. Sell a week too late and you can lose $40-80 on a mid-range device, more than $100 on a flagship — not because anything changed about your phone, but because the market suddenly has a newer thing to want.

The rule is simple to state: sell before the manufacturer announces the next model. For iPhones, that means selling ahead of Apple's September event. For Samsung Galaxy S phones, ahead of Galaxy Unpacked in January. For Google Pixel, ahead of Google's late-summer hardware launch, which has landed in August the last two years running.

Launch timing is the biggest lever, but not the only one. Back-to-school demand, holiday shopping, and carrier promotions all nudge what buyers will pay. This guide puts real numbers to each — using GadgetRenu's live trade-in catalog as of August 2026 — so you can pick your month with your eyes open.

GadgetRenu is a family-owned buyback company in Wallington, NJ, and we pay cash for used phones year-round with free insured shipping from anywhere in the U.S. We still can't rewrite depreciation, though, so here is how the calendar actually hits your payout.

Apple's release schedule is the most predictable thing in the phone resale market. Every year runs on roughly the same rails:

• June (WWDC): Apple previews the next iOS. Almost no effect on resale, but it starts the speculation.
• Early September (Apple event): The new iPhone lineup is announced — in 2026 that’s the iPhone 18 Pro, 18 Pro Max, and Apple’s first foldable iPhone (the base iPhone 18 follows in early 2027). This is the biggest single drop for the outgoing generation — commonly 10-15% inside the first week.
• Mid-to-late September (on sale): New phones ship. Trade-ins pour in all at once, and prices slide further.
• October-November: Values settle at the new, lower level.
• December-February: A small bump from holiday and New Year upgraders, not enough to undo September.
• March-August: A slow, steady grind until the cycle repeats.

A real example: iPhone 16 Pro Max

An iPhone 16 Pro Max tops out at $777 in our catalog right now (August 2026 — top storage, Excellent, unlocked). Apple's September announcement typically pulls 15-25% off last year's models within a month, which on this phone is roughly $115-195 gone before a single new unit ships. The number keeps easing down through October as trade-ins flood the market. Sell in August and you keep that spread.

The same logic covers the whole line. An iPhone 15 Pro tops out at $538 today and an iPhone 15 Pro Max at $607; both are worth more this side of September than the other. If you already know you're upgrading, waiting past the announcement is money left on the counter for no reason.

Our instant iPhone quote takes about two minutes and locks your price for 14 days, so you can grab the pre-announcement value and still have time to move your data over.

Samsung runs on a different clock, which changes the good and bad windows entirely.

• January (Galaxy Unpacked — S series): The new Galaxy S flagship is announced. This is Samsung's version of Apple's September: S-series resale values typically drop 10-15% within days.
• February (on sale): The new S phones ship and used prices ease down further.
• Summer (Galaxy Unpacked — foldables): New Z Flip and Z Fold models arrive. This hits foldable prices specifically and barely touches the S series.

Galaxy flagships generally lose value faster than comparable iPhones. That's a long-standing pattern in the resale market, and our own numbers reflect it. The Galaxy S25 Ultra launched at $1,299 in January 2025; eighteen months later it tops out at $666 in our catalog (August 2026) — roughly half its launch price. A same-era iPhone holds a larger share of its original sticker over the same stretch. More Android models across more price points, and a secondhand premium that still favors Apple, are the usual explanations.

The practical read for Galaxy S owners: sell in November or December, before the January Unpacked. Foldable owners should sell in May or June, before the summer event. Either way, a Samsung quote locks your number for two weeks.

Google Pixel. Google has moved its Pixel launch to late summer — the Pixel 9 arrived in August 2024, the Pixel 10 in August 2025 — so the best window to sell is June or July, before the new lineup lands. A Pixel 9 Pro tops out at $362 today and a Pixel 10 Pro at $492 (August 2026). Once Google announces, expect the usual post-launch step-down; a Pixel quote before August captures the higher figure.

MacBook. Laptops hold value better than phones and Apple refreshes them on a looser schedule, so the timing is softer. Still, a new model resets used prices, so sell ahead of an expected update rather than just after one ships. A MacBook Air 13" M3 (2024) tops out at $807 and the 15" at $863 in our catalog. If yours is sitting idle, a MacBook quote tells you where it stands today.

Set launch events aside and every phone still follows the same downhill shape. Knowing it tells you what waiting actually costs.

• First few months: the steepest part — a new phone can shed 15-25% off retail almost immediately, since sticker prices bake in retail margin and "new" ends the moment the box opens.
• Months 3-12: a slower slide, roughly 2-4% a month, while your phone is still the current generation.
• Successor announced: the sharp cliff — about 10-15% in a week or two as the market reclassifies your phone from "current" to "last year's."
• After that: a long, gentle grind of 1-3% a month. The cliff is already behind you, but the losses keep adding up.

What waiting costs, by device

Top payouts below are straight from GadgetRenu's catalog (August 2026 — top storage, Excellent, unlocked). The monthly-loss column applies a typical ~3-4%/month slide to that value, so treat it as an estimate, not a quote:

The device in your drawer isn't just taking up space — it's quietly getting cheaper. Your actual offer depends on storage and condition; the instant quote prices your exact configuration.

Launches drive the big swings; seasons open smaller windows on top of them.

Back-to-school (July-August). Parents buying phones for students lift demand for affordable used devices, which can firm up offers on mid-range models. This overlaps the pre-iPhone window, which is why late July through mid-August is the strongest stretch of the year to sell an iPhone.

Holidays (November-December). Mixed signals. Bargain hunters want used phones, but aggressive carrier deals on new ones pull the other way. The net is close to flat, with a slight edge for budget and mid-range models that make good gifts.

Tax-refund season (February-April). Refund cash tends to firm up demand for refurbished electronics. For Samsung sellers, though, that's the same stretch the new Galaxy S is dragging prices down.

The spring lull (March-June). The quietest window: no launches, no seasonal push, and buyers know new models are coming. If you're going to sell, don't wait for this stretch to improve, because it won't until midsummer.

A quick reference for the rest of the year. The dates are Apple's, Samsung's, and Google's established launch rhythms; the values behind the moves come from the catalog above.

The most expensive mistake sellers make isn't bad timing — it's no timing. You upgrade, the old phone goes in a drawer "until you get around to it," and months later it's worth a chunk less than the day you stopped using it. The friction is real: back up, wipe, find a box, pick a buyer. Each step is small, and together they keep the phone right where it is.

Idle phones add up in aggregate, too. The UN Global E-waste Monitor 2024 reported 62 million tonnes of electronic waste generated worldwide in 2022, with well under a quarter formally recycled — a lot of that is working devices that never got sold or recovered.

GadgetRenu is built to remove each step of the friction:

• Instant quote in about two minutes — enter your device and condition, see your offer.
• 14-day price lock — secure today's number and take up to two weeks to ship.

If you've got a phone, tablet, or laptop you're done with, the value only goes one direction from here. Start with an instant iPhone quote or a Samsung quote and see what yours is worth today.

How much value does a phone lose when a new model is announced?

Usually 15-25% within about a month of the successor being announced (resale trackers measured the iPhone 17 line shedding ~35% over ten weeks). On an iPhone 16 Pro Max that tops out at $777 today (August 2026), that's roughly $115-195 — and it keeps easing down once the new model actually ships and trade-ins flood in. Selling before the announcement is the single highest-impact timing decision you can make.

Should I wait for my phone to become a collectible?

No. Unlike some cars, everyday consumer electronics don't appreciate with age — an old daily-driver phone just keeps losing value. Sealed, never-opened first-generation iPhones from 2007 have fetched serious money at auction, but that's a sealed-in-box curiosity, not the phone in your pocket.

Does condition matter more than timing?

Both matter, but timing is the one you can still change. You can't un-scratch a screen, but you can choose your month. A pristine phone sold right after a launch can net about the same as a good-condition one sold before it, so the ideal is a well-kept phone sold ahead of the next generation.

Should I sell before or after buying my new phone?

Before, when you can. Get your quote, lock the price for 14 days, then buy the new phone and move your data across. Wipe and ship the old one once everything's transferred. That captures the higher pre-announcement value without any rush — you've got two weeks from the moment you lock in.

I missed the best window — should I wait a whole year for the next one?

No. Another year is another year of depreciation. If you missed August for an iPhone, selling in November or December still beats holding until next summer, when it'll be worth noticeably less. The best month may be behind you, but the second-best is right now — get an instant quote and see today's number.
