The "1-Minute" Review


When it comes to eco-friendly phones, there aren’t many options out there. That’s where Fairphone 4 comes in. While it’s not the top phone out there, it’s probably the most sustainable, and it runs pretty well.

What's good

  • Made with Green materials
  • Durable
  • Good battery life
  • Five-year warranty

What's bad

  • Poor cameras
  • Temperamental fingerprint scanner
  • No headphone jack

In a bid to capture the market with a more eco-friendly phone, Fairphone 4 is made from sustainably sourced materials. It does not look like the best phone out there, just one that doesn’t make a big footprint. What do you lose or gain from having a sustainable, repairable phone?


The Fairphone 4 is built with the rugged, adventurous type in mind. The backplate is made from 100% recycled plastic and has a nice texture. While it’s on the chunkier side, the extra size means this phone can take bumps and bruises easily without breaking.


The 6.3-inch LCD is about average for mid-range phones nowadays. The screen doesn’t have the clarity and the vivid colors of an OLED. However, the brightness was outstanding. Reviewers said it was easy to see in full sun outdoors.


The chipset used in the Fairphone 4 is somewhat older than those of today’s high-end phones. That said, reviewers said it was powerful enough to keep the average user happy. Just don’t plan to play the latest games at the highest settings or expect heavy multitasking to run buttery smooth.

Software & Storage

The phone comes with stock Android 11 installed and a promise for upgrades a long time after its release, potentially up to Android 15. There is the option of 128GB of storage or 256GB. If you should need more space, there is an expansion MicroSD card to help you.


The cameras for the Fairphone 4 are probably the biggest letdown. Pale colors, washed-out details, and a lack of contrast disappointed reviewers. Still, they were not surprised and still considered the phone somewhat competitive based on its price.

Battery Life

If you want a phone that lasts a long time, reviewers said this was it. The Fairphone 4 lasted well into an entire second day for reviewers. There isn’t a fast-charging option. However, the phone is meant to last a long time and be eco-friendly, and fast-charging can shorten battery lifespans.


Reviewers didn’t mention anything in particular about the audio, but given the mid-range price of the phone and its competitors, it’s safe to say it’s probably not that great. There’s no headphone jack, though. So be sure to get an adapter or plan to use Bluetooth if you’d like to upgrade your audio experience.

Specs at a Glance

  • Plastic chassis
  • 6.3-inch LCD
  • Qualcomm SM7225 Snapdragon 750G 5G processor
  • 6/8GB of RAM
  • Android 11
  • 128/256GB of storage with MicroSD expansion
  • 48+ MP camera
  • 3905mAh battery

Bottom Line

The central selling point is that it’s eco-friendly and ethically sourced. It’s rugged, can take a beating, and do most of the basic things we’ve become accustomed to in a phone. The cameras aren’t great, but that’s not what this phone is about. They’re not unusable; they’re just not as perfect as we’re used to.

Tech Radar says, “The Fairphone 4’s eco-friendly resume is reason enough for many people to buy it, but beyond that it’s a strong mid-range phone in all but a few categories. Its battery life is particularly impressive, and its hardy body is protected against bumps and drops, but the cameras leave a lot to be desired.”

The Verge states, “if you just need a smartphone for daily use and aren’t concerned about having the best camera or most premium-feeling device, then I think you’re the kind of person who can live with the Fairphone 4.”

What the Critics Are Saying...

The Fairphone 4 is not only the most ethical smartphone purchase you can make, it’s also a perfectly solid mid-range device that is designed to last at least five years.

Despite the technology update, the Fairphone 4 does not come close to the category leaders Google Pixel 6 and Apple iPhone SE and occupies one of the lower spots in the DXOMARK Camera ranking for High-End smartphones.

From a purely technical perspective, there isn’t too much that’s impressive about the Fairphone 4. Most smartphone selling points can be found implemented better on rival devices and the phone’s mid-range price doesn’t reflect the performance of its hardware. However, if modularity, repairability, a...

Fairphone 4 is based on a sound and sympathetic idea: to avoid obsolescence while ensuring that nothing goes to waste as electronic waste. The idea that users can replace defective parts themselves also appeals to my hobbyist heart. Unfortunately, you cannot replace the processor yourself with a fas...

Fairphone 4 is not suitable for a comfortable gaming experience, with touch lacking precision in corners and the device being too responsive to ghost touches. Furthermore, aliasing is noticeable.
