Samsung Galaxy Z Fold3 5G Battery Replacement
Foldable phones like the Samsung Galaxy Z Fold3 5G often have split battery configurations across the two halves of the device, making battery replacement more involved than on a standard smartphone. If the phone drains faster than it used to, shuts down unexpectedly or only works reliably on charge, the battery has usually degraded. If the phone has been near liquid or the battery appears swollen, treat this as urgent and stop charging immediately. A swollen battery in a foldable can also affect the hinge mechanism. We carry out this repair at our workshop near Liverpool Street Station in London, with UK-wide mail-in available.
- Turnaround: 1 working day pre-order, with fitting normally completed the same day once the part is available
