    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.

    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.

    Super phone, near new condition (exhibition model?) ... Unfortunately it fell flat on the tiles before its protective cover arrived, resulting in a cracked back and the screen no longer lighting up :(

    The battery in this OnePlus 6 128GB - White - Unlocked leaves a lot to be desired. It lasts just over a day without much use. Other mobile phones of the same model have a battery life of almost a week. I'm sorry, but I'm not satisfied.

The OnePlus 6: premium on a budget

This smartphone has all the qualities of a high-end phone manufactured by any one of the well-known market leaders. However, this one does not bear the same price tag, the Chinese tech company has chosen a competitive price point to disrupt the smartphone industry and gain a following of loyal fans. Encased in glass, each OnePlus 6 is fitted with a Snapdragon 845 chip and 8GB of RAM which makes the device just as powerful as other leading models from pricier competitor brands. So, when you buy the OnePlus 6 from Back Market’s range of refurbished smartphones, the price is going to be even lower!

Save on a pre-owned OnePlus 6

Choosing to purchase a OnePlus 6 through Back Market is an easy decision to make, with the high-end performance paired with our low prices, it’s an unbeatable deal. Saving money by choosing a previously owned OnePlus 6 doesn’t mean you sacrifice the quality of your new device; each smartphone is rigorously checked and tested by our specialists to ensure the phone is sold ‘as new’. If that hasn’t convinced you, we even offer a 12-month guarantee in the unlikely event that there is a fault or failure with the phone.

A certified reconditioned OnePlus 6 is a breath of fresh air compared to the usual major phone brands we choose from. Powerful, sleek, and inexpensive, the OnePlus 6 might just be the best deal out there.
