An 'Excellent' refurbished phone may have very little visible wear. That does not, by itself, tell you whether its battery is new or who will repair it if something fails.
Read the cosmetic grade, battery promise and warranty as separate parts of the offer. A clean casing cannot answer all three questions.
What the condition grade actually covers
Back Market's US condition guidance describes Excellent in terms of visible wear. The page states a minimum of 80% of initial battery capacity, while its Premium tier promises at least 90%. These are published thresholds checked on October 24, 2026, not measurements from phones we tested.
That separation is worth noticing. Ask for the minimum battery condition promised at delivery, whether replacement is included, and what happens if the phone falls short. Do not infer a new battery from the adjective or a stock photograph.
Check whose refurbishment programme it is
Named manufacturer programmes can make more specific promises:
- Apple's US Certified Refurbished page says its refurbished iOS devices come with a new battery and outer shell, plus a standard one-year limited warranty.
- Samsung's US Certified Re-Newed programme advertises a certified new battery and a one-year limited manufacturer warranty.
These are promises from those programmes in the US, not features guaranteed with every used iPhone or Galaxy. A reseller selling an Apple phone is not necessarily offering Apple's own refurbishment process.
We have not tested phones from these sellers. This is a comparison of their published terms, not a hands-on ranking.
Put two listings side by side
Imagine two offers for the same model and storage capacity. One has fewer cosmetic marks but an unclear battery policy. The other admits some wear and gives a clear battery guarantee.
Neither wins automatically. For a gift, the exterior may matter more; for your daily phone, battery terms and repair support may deserve more weight. The important thing is to see what you are trading.
Before paying, compare:
- Device: exact model, storage and carrier or network status.
- Condition: cosmetic grade, battery promise and parts information.
- Support: warranty provider, return conditions and remaining manufacturer software support.
Do not count software support from your purchase date. For example, Google counts the update window for Pixel 8 and later phones from their first availability in the US Google Store. Check your exact model and local warranty terms before importing a phone.
Check the phone while you can still return it
When it arrives, compare the device with the saved listing. Check charging, cameras, speakers, buttons, display and connectivity, and confirm you can complete legitimate setup with your own account.
For an iPhone, Apple advises against buying an Activation Locked device and says to return an online purchase that shows Locked to Owner. Report other mismatches promptly with photographs and a description of what fails. Keep the invoice and listing terms so the complaint points to the promise you actually bought.
