Refurbished Tech Checklist: What to Check Before Buying a Used Laptop, Phone, or Tablet
Refurbished tech saves money — or hands you someone else's problem. A pre-purchase checklist for used laptops, phones and tablets: account locks, battery health, software support, carrier locks and a physical once-over.

Refurbished and used tech can save you a lot of money — or hand you someone else's problem. The difference is a few minutes of checking before you pay. Whether you're eyeing a used laptop, phone, or tablet, run through this checklist first. It catches the expensive surprises: dead batteries, locked devices, and gear that's already lost software support.
Before you buy: seller and source
- Buy from a reputable source when possible — manufacturer-refurbished or a seller with a real return policy beats a random listing.
- Check the return window. Even a short return period lets you test the device properly at home.
- Be wary of "too cheap." A flagship at a fraction of its price is often locked, stolen, or broken.
The non-negotiable checks
These are the ones that cost real money if you skip them:
- Activation/account locks. Confirm the device is signed out of the previous owner's account (Apple Activation Lock, Google/Samsung account, Windows account). A locked device is a paperweight — verify it boots to setup, not someone's login.
- Battery health. On phones/laptops, check the battery health percentage in settings. Below ~80% means a near-term replacement cost. A "great deal" with a worn battery often isn't.
- Software support window. Check whether the device still gets OS and security updates. An older model abandoned by its maker is a security risk and won't get new features.
- Storage health. Confirm the stated storage is real and the SSD/eMMC isn't failing (no constant slowdowns or errors).
The physical once-over
- Screen: look for cracks, dead pixels, burn-in (especially OLED), and touch dead zones.
- Ports and buttons: test charging, USB ports, volume, power, and the headphone jack if present.
- Camera and speakers: snap a photo, play audio.
- Wi-Fi, Bluetooth, cellular: connect to each; on phones, confirm it's not carrier-locked if you need it unlocked, and not blacklisted (clean IMEI).
- Hinges/chassis (laptops): check the hinge isn't loose and the case isn't cracked.
Accessories and extras
- Charger and cables included? A missing proprietary charger adds cost.
- Original box/proof of purchase can help with any remaining warranty.
Quick pass/fail table
| Check | Pass | Walk away if |
|---|---|---|
| Account/activation lock | Signed out, boots to setup | Stuck on a login |
| Battery health | ~80%+ | Well below 80% (unless priced for it) |
| Software updates | Still supported | Abandoned by maker |
| Carrier lock (phones) | Unlocked / your carrier | Locked to another carrier, clean IMEI unverified |
| Physical | Clean screen, working ports | Cracks, dead pixels, failing ports |
Who it's for
- Budget buyers who want flagship capability for less.
- Parents/students buying secondary devices.
- Anyone swapping to a newer used model instead of paying full price.
Bottom line
A refurbished device is a great deal only after it passes the checks: signed out of all accounts, healthy battery, still getting software updates, no carrier lock, and clean physically. Buy from somewhere with a return policy, run this list within the return window, and you'll get the savings without inheriting someone else's worn-out, locked-up problem.
