Charging Slowly

Various Wireless Charger

Severity: Minor

What Does This Error Mean?

Slow wireless charging is usually caused by a weak adapter, wrong protocol, or a thick case. Use the adapter that came with the charger and remove your case for maximum speed.

Affected Models

  • Anker PowerWave
  • Samsung Wireless Charger
  • Apple MagSafe
  • Belkin BoostCharge
  • Most Qi wireless chargers

Common Causes

  • Wall adapter too weak (5V/1A instead of 9V/2A)
  • Phone and charger using different fast-charging protocols
  • Thick case reducing efficiency
  • Phone too hot — thermal throttling reduces charge speed
  • Background apps keeping the phone active

How to Fix It

  1. Use the adapter that came with the charger.

    Fast wireless charging needs a Quick Charge or USB PD adapter. A basic 5V/1A adapter only gives 5W charging.

  2. Remove the phone case.

    Even thin cases reduce efficiency slightly. Removing the case typically improves speed by 10-20%.

  3. Turn off the phone screen and close apps.

    An active phone uses power while charging, reducing net charge speed. Lock the screen and let it charge.

  4. Make sure the charger supports your phone's fast wireless standard.

    Samsung: 15W with Samsung chargers. Apple: 15W with MagSafe, 7.5W with standard Qi. Mismatched protocols default to 5W.

Frequently Asked Questions

Does MagSafe work with non-Apple phones?

MagSafe is an Apple standard. Non-Apple phones charge at regular Qi speeds (5-7.5W) on MagSafe chargers. Some Android phones support Qi 2.0 which is MagSafe-compatible.
