Selling your phones: FAQs
The questions sellers ask most, answered plainly.
Which phone is worth the most right now?
As of October 14, 2026, the Galaxy Z TriFold is the most valuable phone Techtree buys, at up to $2,070 for a brand-new unit and up to $1,555 in good condition. The iPhone Duo is next at up to $1,860. Prices are for a complete, working device; the wizard shows the exact figure for your storage, carrier and condition.
How fast do phones lose value?
Across the 204 phones Techtree has priced for long enough to measure, what we pay in good condition fell 2.7% over roughly the last 90 days (as of October 14, 2026; a model priced for under 90 days is measured from its first price). The LG V60 ThinQ 5G moved the most (-68.8%) and the Galaxy S25 held best (+37.2%). Values for most devices fall over time, fastest in the weeks after a successor launches, so a device is worth the most the day you sell it.
Which phone models does Techtree buy?
Techtree buys 220 phones from the iPhone 8 Plus (September 2017) to the iPhone Duo (October 2026), paying from $25 (iPhone 8) to $2,070 (Galaxy Z TriFold) for a phone in brand-new condition as of October 14, 2026. Every model listed on this page has an instant quote, free prepaid shipping and a 21-day price lock.
What's the best way to sell my used phone?
You can list it on a marketplace, trade it in with a carrier, or use a buyback service like Techtree. A buyback gives you a locked, upfront price with free prepaid shipping and no listing hassle or fraud risk, usually the fastest and safest option.
Does carrier or storage affect my offer?
Yes. Unlocked phones are worth the most, and higher storage tiers earn more. We ask for both during the quote so your price reflects your exact configuration.
Should I factory reset my phone before sending it?
Yes. Back up your data, sign out of your account, turn off activation lock and Find My, remove your SIM, and erase the phone before you ship it.
When is the best time to sell my phone?
Usually right before a new model launches, since older models hold value best before the announcement. Lock your quote now and you have 21 days to ship.
