Fast charging features that is not working as it should be on LG V20 is a troubling issue, but no need to worry because there are couple of things that you can try to solve this problem and have the feature work back to normal.
Fast charging feature on LG V20 work as the name stated. It will charge your device faster than the usual charger. It will charge the phone from 0% to 80% in just 30 minutes or so. After that, it will resume its charging process in normal speed. It is a nice feature to have because you don’t have to wait for hours just to get your phone ready to use.
Now, if you notice that the fast charging feature is not working properly, then you need to fix it right away. You may find that after 30 minutes, the charging percentage is still way below 80% or perhaps when you pull down the notification shade, there is no notification about fast charging.
First thing to try and this is a common sense talking, is not to use the phone while it still charging. No matter what kind of charging that you use, either fast charging or normal charging, it will work slower than it should be if you use it. Just leave the phone be so it will work effectively and soon you can have your phone back with full battery level.
You also may want to take a look on the cable and charger that you use. Make sure that it supports Quick Charging 3.0. Use the one that comes with the device or look for it from trustable store.
The cable and charger that support this feature was made specifically so it will amplify its charging power, thus make it able to charge faster. If it doesn’t support this feature, then it will work in normal pace, so make sure to get the right charger.
The fast charging feature should be working properly right now, and if it’s not, then you need to do thorough inspection on the phone to find out what is wrong with it and have it work out right away.
