Samsung Galaxy S23 Ultra not charging reliably?
Losing fast charging, losing the cable connection and losing all charging are different symptoms. We assess what your S23 Ultra actually does before recommending a port or board repair.
The fixed £35 diagnostic covers the assessment described below and both-way UK tracked shipping. If you approve the repair quote, the fee is deducted from that quote. No repair work starts without your approval.
Model-specific context
Separate fast charging from a connection failure
The Galaxy S23 Ultra supports USB-C and wireless charging. A change in the fast-charging message can depend on the charger, cable and device conditions; it is different from receiving no power at all. Tell us whether the battery rises with a direct charger, whether wireless charging was working and whether the USB connection also drops during computer use.
For the wider fault pattern, read the Phone charging diagnosis. If the files matter more than returning the device to daily use, read about data recovery and select Data recovery when booking.
The symptom
Include the charging message and battery behaviour
These observations help distinguish a setup problem from internal damage:
- Cable charging repeatedly disconnects or requires a particular angle
- Wireless charging works but the USB-C route does not
- The charging label changes and the battery gains little or no charge
What the diagnostic checks
What we check on your Samsung Galaxy S23 Ultra.
- Inspect the USB-C socket and connections for wear or contamination
- Compare suitable charging equipment with the battery response
- Investigate the device power path when connector and supply tests do not explain the failure
We’ll explain what we find in writing and quote for the work we can offer. Your options depend on the device’s condition, our test results and the parts available.
Before you post it
Protect the device and the data while deciding.
- If safe, compare one known-good adapter and cable without forcing the socket
- Record any moisture or temperature warning and stop charging if one appears
- Describe whether the phone has had a battery or charging-port replacement

Tell us what’s happening with your Samsung Galaxy S23 Ultra. We’ll assess it at our Tyneside lab for £35 and explain your options before you decide on repair.
Fast-charging loss alone does not identify a broken port
Charging mode depends on more than the socket. The assessment explains which behaviour is abnormal and what further work is justified. Board condition and available parts determine the repair options and quote.
Common questions
Samsung Galaxy S23 Ultra not charging FAQ
Do I need a new port if Super Fast Charging disappeared?
Not necessarily. The power adapter, cable, settings and temperature can affect charging mode. We distinguish that from a physical connection or device power fault.
Does working wireless charging rule out battery damage?
No. It is useful evidence of one charging route, but the battery and shared power circuitry still need assessment if charging or runtime is abnormal.
Can you assess it after a previous charging-port repair?
Yes. Explain whether the symptom improved at all and how long that lasted. The history helps guide connection and board checks without assuming the same part failed again.
