The Fairphone 4 battery holds all the power. Literally. Even when you’re low on battery, you’ll get up and running within half an hour.

Overall, your battery will last about 13 hours with phone calls. Keeping you going all day long. But the best part is that we’re working with the Fair Cobalt Alliance to integrate fair cobalt and responsible lithium into the supply chain. Now that’s long-lasting.

If you are buying a new battery to solve issues related to charging, phone stability, or the phone not switching on, we would recommend reaching out to our customer support desk first. They will be able to confirm if the battery is at fault, or if it is something else that needs to be looked at.
