Charging Slowly
Various Wireless Charger
Severity: MinorWhat 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
-
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.
-
Remove the phone case.
Even thin cases reduce efficiency slightly. Removing the case typically improves speed by 10-20%.
-
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.
-
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.
