Symptoms
- Wireless charging takes much longer than wired charging on the same phone
- Percentage climbs very slowly on the pad compared to a cable
- Charging speed varies depending on exact phone placement
- A basic pad charges noticeably slower than a premium one
Likely causes
- CommonCharging pad rated below the phone's maximum wireless charging wattageA basic 5W or 7.5W pad charges much slower than a pad rated for the phone's full wireless fast-charge speed.
- CommonPhone slightly misaligned with the coilEven minor misalignment reduces charging efficiency and speed.
- CommonWireless charging is inherently less efficient than wired chargingSome energy is lost as heat in wireless power transfer, so it's normally slower than a cable even under ideal conditions.
- PossibleA case adding distance between the phone and the coilExtra thickness from a case reduces charging efficiency and speed.
What to do
- Check the charging pad's rated wattage against your phone's maximum supported wireless charging speed.
- Remove any case and center the phone carefully on the pad's marked charging spot.
- Use the specific wall adapter recommended for the wireless pad, since an underpowered one limits output.
- Compare wired versus wireless charging speed on the same phone to set realistic expectations.
- Try a different, higher-wattage wireless charger if the current one is basic or older.
- Avoid using the phone while it's wirelessly charging, since active use further slows net progress.
- Check for any debris or a case pocket item interfering with contact.
- If wired charging is fast but wireless is unusually slow even with a matched charger, consider it a normal wireless charging limitation rather than a fault.

When to call a pro
This is generally normal wireless charging behavior; if it's dramatically slower than expected even with a matched charger, have the wireless coil checked.
