Fast charging is one of the most convenient features on the vivo S50, especially when you need power quickly. When it suddenly stops working, charging feels slow and unreliable, even with the original charger. In most cases, the problem is caused by settings, accessories, or temporary system behavior, not permanent hardware damage.
Why Your vivo S50 Fast Charging Is Not Working
- Fast charging is disabled in system settings.
- The charging cable or adapter does not support fast charging.
- Dirt or lint is blocking the charging port.
- The phone is overheating while charging.
- Background apps are interfering with charging speed.
Enable Fast Charging in Settings
Fast charging can be turned off manually on some vivo phones. When this happens, the phone still charges, but only at normal speed.
Open Settings, and then tap Battery.
Tap Charging settings, and then make sure Fast charging is enabled.
Check the Charging Adapter and Cable
Fast charging only works when both the adapter and cable support higher power output. Using a regular charger or a damaged cable limits charging speed.
Plug in the original charger, and then connect the original USB cable.
Try a different fast charging cable, and then test charging again.
Clean the Charging Port
Dust and lint inside the charging port can prevent proper power delivery. Even a small blockage can stop fast charging from activating.
Turn off the phone, and then unplug the charger.
Use a soft brush or wooden toothpick, and then gently clean the charging port.
Let the Phone Cool Down
When the vivo S50 gets too warm, the system automatically slows charging to protect the battery. This makes fast charging appear broken even though it is working as designed.
Remove the phone case, and then place the phone on a flat surface.
Wait a few minutes, and then plug the charger back in.
Close Background Apps While Charging
Heavy background activity increases heat and power usage. This can prevent fast charging from kicking in properly.
Swipe up to open recent apps, and then close unused apps.
Lock the screen, and then leave the phone untouched while charging.
Restart the Phone
Temporary system glitches can interfere with charging detection. A restart refreshes the charging service and often restores fast charging.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up, and then connect the charger again.
Fast charging on the vivo S50 usually comes back once the right conditions are met. After checking settings, accessories, and temperature, charging speed should return to normal without further issues.
FAQs
Why does my vivo S50 say charging but not fast charging?
This usually means the charger or cable does not support fast charging, or the feature is disabled in battery settings.
Does using the phone while charging disable fast charging?
Yes. Heavy usage creates heat and increases power draw, which can force the phone to slow down charging speed.
Can software updates affect fast charging?
Yes. Some updates reset battery or charging settings, which may turn off fast charging until you enable it again.
