Fairphone 4 Battery

The original Fairphone 4 battery has a lot going for it. It reliably keeps your phone up and running all day long. It comes with convenient fast-charging technology that jumpstarts you back to 50% of its 3905mAh capacity in half an hour (when using chargers with a 20W minimum).

And it’s probably the world’s easiest and fastest spare part replacement. When the time comes to replace your battery, you don’t have to be an expert to swap it out in only a few seconds.

But wait, there’s more than meets the eye. Behind the scenes, we’re innovating where it counts: We’re working with the Fair Cobalt Alliance to integrate fair cobalt and responsible lithium into the supply chain.

About as fair as they come!

Pro-tip: Works great as a spare-battery too, if you’re on the go and need to double your battery-life.

The battery will keep 90% of its original capacity after being charged 547 times (full cycles). Nominal capacity: 3905 mAh/15.03Wh. Nominal voltage: 3.85V
