Our Refurbished iPhone 15s are Guaranteed to Have
85% Battery Life
We're dedicated to providing reliable, long-lasting phones. Even our 'poor condition' pre-owned phones maintain at least 85% battery health, ensuring extended usage with fewer interruptions. This is higher than many competitors, who offer devices with lower battery life.
Battery life measures how well a battery retains charge compared to its original state. An 85% battery indicates the battery is in good condition, offering better performance and longer usage between charges, almost like a new battery. This percentage reflects efficiency, not charging capacity.
12 Month Warranty
Most devices come with a 12-month warranty. This means your purchase is protected for a full year against any material defects. If something goes wrong that’s covered by the warranty, the store will help solve the issue at no extra cost. It’s all part of our commitment to ensuring you have a reliable and worry-free experience with your device. To find out more, visit our warranty page.
Testing a refurbished iPhone
Each refurbished product undergoes a thorough process, with over 90 individual checks to ensure it meets our high standards. These check every aspect of the phone, including its functionality, battery status, screen quality, and overall condition. We guarantee that every phone we sell is in great working order and ready for reliable use. Many competitors do not offer such an extensive process, so phones from competitors might not meet the same high standards.

Our Refurbished iPhone 15 Conditions Explained
Our grading conditions range from 'Brand New' to 'Poor', so you can pick your device to suit your budget! For first-time buyers, we recommend buying 'Like New' or 'Pristine'.
Brand New—sealed as you would expect. These phones have never been used before, and they even come with their manufacturer's warranty!
Like New- Almost New (Out of Box). This is our best-refurbished product with premium condition, and the device has no cosmetic damage. Besides not being in the original box, this device is essentially brand-new!
Pristine—Very Slight Signs of Use. Our pristine phones clearly show that the previous owner has taken great care of their device, so while there may be some minor cosmetic imperfections, 99% of the phone is in perfect condition.
Very Good- Light Signs of Use. These phones show light signs of usage and may have visible cosmetic marks, but they won't be visible when the screen is on. Buying 'Very Good' is ideal for those who are budget-conscious and don’t mind a few imperfections.
Good- Medium Signs of Use. These are phones that have had a few bumps! There are visible cosmetic marks, and the device shows medium signs of use, but its functionality is completely unaffected!
Poor- Heavy Signs of Use. Fully tested and in perfect working order, these phones are the cheapest way to get the model you want at the cost of cosmetic quality. Scratches, cracks, and screen burns are all possible.
