When does the Fairphone 3 need a new battery?
The Fairphone 3 launched in 2019 and offers an improved modular architecture compared to the FP2. The 3,040-mAh battery gives the device noticeably more reserves — but after a few years and several hundred charge cycles, the capacity drops off noticeably. Typical signs:
- Battery is empty after just a few hours, even though it easily lasted a day before
- Device suddenly shuts off at 15–20 % battery level
- Battery indicator jumps from 40 % straight to 10 % or makes similar jumps
- Charging takes unusually long or occasionally fails
- Battery shows visible deformation or swelling — immediate action needed

Quick test: another USB-C cable + power adapter. If power still does not get through — usually an oxidized USB-C port (charging port repair). If the battery charges but drains fast again — the cell is at its end, battery replacement 69 €. Diagnostic check 25 € clarifies up front, waived on repair order.
