Fairphone 4 review: The repairable, ethical 5G phone that promised support into 2027.
The conscience phone, first generation of 5G.
Fairphone 4 was the proof that a fully repairable, ethically sourced phone could still do 5G and last for years — with a swappable battery and support promised into 2027. On raw specs the 60 Hz LCD and 750G were ordinary even in 2021; as with every Fairphone, the values are the product and the benchmarks come second.

- Fully DIY-repairable with a swappable battery.
- Ethical, fair-labour, recycled-material supply chain.
- 5-year warranty, support targeted to 2027.
- 5G with dual 48 MP cameras.
- 60 Hz LCD and Snapdragon 750G feel dated for $649.
- Heavy 225 g, single speaker, no jack.
- 20 W charging, no charger in box.
- You pay for ethics, not specs.
