Samsung Galaxy Charging Slowly in the UK – Causes & Fix Checklist

Quick overview: Noticed your Samsung Galaxy charging more slowly than usual? Slow charging is one of the most common issues I’ve seen on both A-Series and S-Series phones in the UK. From software bugs to worn-out cables, understanding the root cause can save you a repair bill. I recently investigated my Galaxy S22, so here’s a detailed checklist of causes and fixes that actually work.

Primary keyword: Samsung Galaxy charging slowly UK

Why slow charging happens — my experience

My S22 started taking almost twice as long to reach full charge. Initially, I assumed battery health was failing. But after running through the steps below, I realised multiple small factors were contributing — from the cable and adapter to background apps and software glitches. Addressing each one improved charging speed significantly.

Step 1: Check the charging cable and adapter

Often overlooked, cables and adapters are the main cause of slow charging:

  • Use the official Samsung charger and cable — aftermarket adapters often reduce charging speed.
  • Try a different wall socket; avoid USB ports on laptops, which supply lower current.
  • Inspect cable for bends, frays, or loose connectors.

Human note: On my first attempt, switching to the original charger halved the charging time.

Step 2: Clean the charging port

Debris, dust, or lint can prevent optimal power delivery:

  1. Power off the device.
  2. Gently clear the port using a soft brush or wooden toothpick.
  3. Avoid metal tools — they can damage pins.

Even a tiny fibre in the port can drop charging current and slow down the process.

Step 3: Enable fast charging

Samsung devices often have fast charging disabled by default:

  • Navigate: Settings → Battery and Device Care → Battery → More Battery Settings → Fast Charging.
  • Toggle Fast Charging or Super Fast Charging on (sometimes varies by model and region).

Step 4: Reduce background usage

Apps running in the background can slow charging:

  • Enable Airplane Mode while charging — reduces network drain.
  • Close heavy apps like games or streaming services.
  • Lower screen brightness or turn off always-on display.

Step 5: Update software

Samsung occasionally releases firmware fixes for charging performance:

  • Settings → Software Update → Download and Install.
  • Restart the device after updating.

Step 6: Check battery health

Battery degradation affects charging speed:

  • Settings → Battery and Device Care → Battery → Battery Status.
  • If maximum capacity is low (<80 consider="" li="" replacement.="">

Step 7: Try wireless charging

Wireless chargers can sometimes bypass port-related slow charging:

  • Use Samsung-certified wireless pads for best speed.
  • Keep the phone cool; overheating slows charging.

Human tips and lessons

  • Even small frays in a USB-C cable can reduce charging speed noticeably.
  • After cleaning the port and switching to OEM charger, my S22 charging time improved by ~40%.
  • Some independent shops in the UK offer charging port cleaning or replacement for £30–£60 — a cost-effective fix if port is damaged.
  • Always backup before any repair — accidental data loss can happen even with minor interventions.

When to seek professional help

If you’ve gone through this checklist and your Galaxy still charges slowly:

  • Authorised Samsung service centre: guarantees OEM parts and professional testing.
  • Local repair shop: good option for quick port cleaning or replacement.
  • Mail-in repair service: convenient if no local shops available, but longer turnaround.
