How to buy a used Fitbit

Battery life is the thing that fades. A Fitbit's selling point is going days between charges, and that shrinks as the sealed battery ages, so ask how long a charge lasts now. The battery is not user-replaceable, so a tracker that needs charging daily is near the end of its useful life whatever it looks like.

Confirm it is unpaired and check the charger. The device must be removed from the previous owner's Fitbit account or you will struggle to set it up, so ask them to factory reset and remove it. Fitbits use proprietary charging cables that differ between models and are easy to lose, so make sure the correct one is included, as buying the right cable separately is a hassle.

Mind discontinued models and worn bands. Some older Fitbits have been retired and lose app features over time, so check the model is still supported. Bands wear and can harbour grime but are cheap to replace, so a tatty strap is not a reason to walk away. Confirm the heart-rate sensor and screen work, as those are the parts that matter.

Value. Fitbits depreciate quickly, so a recent supported model with good battery life can be had for well under half of new.

Common questions

Which Fitbit has fallen furthest

Each tracker as a percentage of its launch price. Fitbits fall harder than anything else on this site, at a median of 23 per cent, and the pattern is plainly age rather than anything Google did to the app: the 2015 and 2016 models sit between 8 and 20 per cent of launch while the 2022 and 2023 ones sit between 30 and 51. A Charge 2 at 8 per cent works out around twelve dollars, less than a replacement band costs, so on the oldest rows the real question is battery health rather than price.

Cheapest by model, at a glance

A daily snapshot of the lowest genuine eBay price for every model we track, and how good that price is right now versus its usual level, updated automatically. Prices last refreshed 22 September 2026 . Tap a price to see that model's cheapest listings on eBay, or tap a model name for the full live list here.

Under each model is the actual listing that price came from, so you can see whether it is the thing you want or a bundle, a variant, or an accessory that happens to share the name.

"Off retail" compares today's used price with what the model costs new. For anything still on sale that is its current new price, so the figure is close to a discount you could really get. For anything no longer sold it is the last new price we have on record: on a boxed product like a LEGO set or a console that is the RRP, and on a part like a graphics card it is nearer what new stock was going for at the end than what it cost at launch. So on older hardware read it as depreciation against late retail rather than against the original sticker. A few rows read "above" instead: they cost more used than new, which is normal for a retired set or a part nobody makes any more.
