Why Isn T My Fast Charger Working. This is a wrong concept. Wait at least 10 seconds.
But sometimes some mishap or carelessness could result in the charger or the laptops charging abilities to malfunction. Some wireless chargers do have a fast-charge mode but itll only work with phones from the same manufacturer. There are a few troubleshooting options such as.
If not check if you use the original items and if they are connected properly.
So after a quick google search it appears my s21 ultra will not fast wireless charge using a non Samsung charger like the big that was reported with the s20. Also make sure you are using the original data cable and charger for your Galaxy S7. If it actually fully charges after an hour from 10 and below then its fast charging. If you insert the cable into the phone too slowly or have not connected them properly fast charging may not work.
