A Galaxy Z Fold5 charges at 25 W wired and 15 W wireless, so a slow charge on an old brick is expected; a Fold5 that does not charge at all is usually the port, the cable or a foldable-specific detail. The Fold5's battery sits in two halves, which is why a single charge shows as one percentage.
Charging threads from Fold owners describe foldables that do not fast charge and that run hot even on 20 W chargers, and a charge that takes hours to climb a few percent. Check the lock screen label, clean the USB-C port, and use a Samsung 25 W adapter with a 3 A cable. If the Fold5 only charges when held at an angle, the port is worn, and Samsung can replace it at a service center. Do not charge a foldable that is warm or whose inner screen shows damage.

Record this first — changing settings destroys the evidence
- The adapter and cable and whether they charge another phone
- The lock screen label while charging
- Whether the foldable is warm

Model-specific
What is true of this model and not of its siblings
- The rates
- 25 W wired and 15 W wireless on the Fold5.
- Heat
- A foldable's thin halves shed heat poorly, so charge idle.
- Charging both halves
- The Fold5 shows one percentage, but a split battery means a fault in one cell or its connector can make the whole phone charge slowly or stop early; Phone diagnostics checks the pack as a whole.
- What to avoid
- Do not charge a foldable on a soft surface, in a thick case or in direct sun; the thin halves hold heat and the phone will slow the charge.
Stop boundary
When this stops being a self-service repair
- !If two known-good chargers fail with a clean port, book a Samsung repair
- !A hot or swollen foldable must go to service
- !If charging is slow only after One UI 8.5, report it to Samsung Members
