    I'm happy to say that the physical condition of the device was better than expected and my worries about the battery life were unfounded! I understand the reason behind the minimal packaging and, in some sense, even loved it. But I wouldn't mind having another layer of protection for the device. In summary, great value for money! I hope to use this phone for a long time.

    phone charge port intermittent charging and headphone jack does not work no music through headphones. contact customer service, directs you to your account that says sorry, no orders as yet. back to the beginning, same again!! phone has to be put into a 3rd part to fix at my expense as I can't get through to this company, cost £70! What use is a years warranty if you can't make a claim. Would I recommend or buy again? NOPE! unfortunately, the quality control department has not done its job on thei occasion!

    Bought this One Plus 6 in order to install Linux on it to experiment and test the state of linux on smartphones in 2024. The product photos therefore show it running PostMarket OS, not OxygenOS-Android. About my experience with BackMarket: Sometimes difficult to know where the package is, and the box is much too big compared to the contents. However, in my case the phone was well secured in the box and therefore protected from shocks, contrary to what you might hear from other reviews. Concerning the condition of the phone: The phone is in excellent condition, I have the impression that it is as good as new. It came with a charger, which is probably not the original one, but it works. Before installing Linux on it I obviously quickly configured Android (Oxygen OS in the case of the One Plus) to install BackMarket and do the tests: everything worked. I didn't test the battery under Android because I was impatient to start my experiment, but under Linux, without using the laptop (in standby) the battery lasts much longer than 2 to 3 days. Regarding my experience with Linux : I was able to install linux (postmarket OS) on it without any worries via the web flasher after unlocking t...

    Came as a gift for my son and has worked perfectly so far... cool and a good alternative to a new phone! The kid has been really happy and hasn't noticed that it's not a brand new one.

Reborn vs. brand new

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

77.3 kg of carbon

That’s like driving an old banger from London to Edinburgh and back.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

77,000 litres of water

That's like running a faucet for 3 days
