The Fairphone 4 which is based on a Qualcomm Snapdragon 750G SoC, 6GB of RAM, and 128GB of storage - upgradeable to 8GB and 256GB - is based around several promises from the maker.

It has a "fair" supply chain -- both ethically-clean raw materials and paying workers a fair wage -- it also describes the 4 as "e-waste neutral." And the company will recycle one device for every Fairphone 4 it sells.

Fairphone can boast that it now uses 70 percent "fair" materials inside the handset, including FairTrade Gold and Silver, aluminium from ASI-certified vendors, and a backplate made from post-consumer recycled polycarbonate.

In an upgrade to previous models, the Fairphone 4 has dual cameras, though it loses the headphone jack. The company says this was to achieve an IP54 waterproof rating (light splashes) -- a first for the Fairphone brand. It's also been announced that it will come with an industry leading five year warranty and aims to get 6 years of software updates for the phone.

On the front, there is a 6.3-inch, 2340x1080 LCD display with slimmer bezels and a teardrop notch for the 25-megapixel front camera.

The 3,905mAh battery is Qualcomm Quick Charge 4.1 compatible, so if you have a compatible USB-C charger (not included in the box to reduce waste) you can take the battery from 0-50 per cent in 30 minutes. The phone ships with Android 11 and has a side-mounted fingerprint reader in the power button, a MicroSD slot, and the option for dual-SIM usage via one physical nanoSIM and an eSIM. The phone will cost EUR 579.
