Intro: Rise of the Space Black Phoenix: The iPhone 14 Pro 256GB from Back Market isn’t just a phone; it's a comeback story in a sleek Space Black suit. Unboxing this beauty felt like revealing a secret agent gadget – classy, cool, and with a license to thrill. Craftsmanship: Darth Vader Would Be Jealous: This phone’s build is so premium, it makes other phones look like they’re wearing hand-me-downs. Space Black is not just a color; it’s an attitude. And refurbished? More like, it's been to a spa and back. Performance: Like a Cheetah on a Rocket: Powered by the A16 Bionic, this device is faster than my ability to make puns. 256GB means I can hoard apps like a digital squirrel and still have room for more. Photography Wizard: Hogwarts Certified: The camera turns every shot into a masterpiece. I mean, if Van Gogh had a smartphone, this would be it. Night mode isn't just a feature; it's a nocturnal magic show. Display: Your Eyes Will Thank You: The Super Retina XDR display is so vibrant, rainbows would feel insecure. And with ProMotion, scrolling is smoother than my best pick-up lines. Battery Life: Energizer Bunny's Role Model: It lasts longer than my resolve to avoid sweets. And ...

So far I am absolutely delighted with my refurbished iPhone 13 it is everything it said it would be. It came very quickly and well packed. I haven’t yet received the refund on my iPhone 11. Once the money is in the bank . This is the second refurbished phone and an Apple Watch from Back market and they have all been excellent. The exchange refund on my iPhone 11 worked brilliantly. Money safely in the bank so upgrade achieved painlessly and for a reasonable outlay.

iphone 12 pro Fair grade 》 Iphone 12 pro excellent grade. I just want to say it my first experience buying used refurbished mobile. i have been buying brand new apple from more then 10 years and i'm the kind pf person who loves keeping the gadgets mobiles laptops in a flawless condition. i came across this site and accidently ordered a fare grade mobile which was very rough and according to the website description. After one of receiving the order I came to know the site has option to select grades so I immediately returned the device. Then I reordered the same phone from same seller in excellent grade and seriously I'm amazed with conditioned it really give you a brand new phone vibe. Cons: customer support not responds timely. no helpline no to call very canned responses. can improve packaging a bit battery health are okay first phone was 83 and the next one i reordered was 84 pros you can get a phone exactly according to your budeget 12 months warranty plus extended covers as well for 35£ very cheap recommendation. dont go for fair grade you wont like that but they have very clear details about each single grade so atleast go good grade or excellent. i got my excellent grad ...

Aye my refurbished iPhone 13 is grand. Phone came quickly and well wrapped. It’s a Fair model so it has bumps and paint scrapes but no dents or bashes. The battery goes up to 100% which I’m chuffed about. Refurbished phones are definitely the way forward. Has taken a bit of time going from a Samsung to Apple, no proper back button and the set up of picture scrolling and a few other things aren’t as good. Will probably go back to Samsung with my next phone but wanted to try Apple for once. Would highly recommend BackMarket, good little unit altogether.

Decided to try out a refurbished phone and have to say i'm really impressed. went for an iPhone 12 in "good" condition and it's in perfect condition. Battery percentage is at 85% but i don't mind that as i know it will still have an original apple battery

Benefits of buying a refurbished Android smartphone


At Back Market, customers save up to 50% off compared to the price of new on certified refurbished Android smartphone models. The best part is, you don't have to sacrifice performance quality in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or second hand Android smartphone compared to a refurbished one.

Buying a reconditioned Android smartphone is also an environmentally friendly option. A refurbished Android smartphone is often a second hand device that has been restored and updated to meet manufacturer standards, which means you'll be helping to keep old Android smartphones out of our landfills, reduce electronic waste, and minimise your carbon footprint.

 

 

Where to find a cheap refurbished Android smartphone?


If you're looking for cheaper Android smartphone options and don't want to pay full price, you'll find the biggest selection, highest product quality and lowest prices on restored Android smartphone models at Back Market. That's because we specialise specifically in refurbished tech and take the time to carefully vet every seller on our marketplace to ensure customers are getting reliable devices that perform like-new. We have several refurbed Android smartphone in price ranges to fit almost anyone's budget.

Staying true to our brand, we're also a huge advocate for environmental change. In fact, at the beginning of 2023, we hit a milestone for preventing 1 million tons of carbon emission (CO2e) from entering the atmosphere. You can help contribute to a better circular economy when you shop Android smartphone deals on our platform. 

 

What to expect when buying a refurbished Android smartphone?


If you're a first time refurbished buyer, you might not be sure what to expect from your purchase. First, understand that your Android smartphone may have external cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, any external blemishes will not affect the performance of your Android smartphone and you can expect your device to perform as if it were newly opened directly from the store.

You should also be confident that your Android smartphone is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement.
