Galaxy not fast charging
Samsung Galaxy not fast charging: charger, settings or heat
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Your Galaxy charges slowly instead of fast charging. Samsung links this to the charger, the charging settings, heat, debris in the port, Battery protection or moisture. Check that fast charging is on and that the charger is genuine and rated at least 15W.
Safety first
Stop and check this first
- Do not clean the charging port with metal objects or liquids; Samsung only suggests gently blowing out dust with the phone turned off.
Safe checks you can perform
- Turn on fast charging
- Use a genuine charger that is powerful enough
- Look inside the port with the phone off
Leave these tasks to a qualified professional
- Do not attempt this professional task: Samsung service centre inspection

What it means
Samsung says fast charging should be enabled when using an adaptive fast wired charger of 15W or higher, and fast wireless charging needs a charger of 9W or higher. The setting is in Settings > Battery > Charging settings and cannot be changed while the phone is charging. Samsung lists high device temperature, the charging accessories, the charging settings, debris in the charging port, Battery protection and moisture as reasons a Galaxy may charge slowly. Slow charging alone does not prove the battery or the port is faulty.
