Samsung note 5 fast charging feature stopped working every time. Intermittently worked. Frustrating as all get out. (What does all get out even mean?)
I have three fast chargers and it worked on all three chargers then one day it just stopped fast charging. I spent a lot of time trying to figure the issue. Deleted cache. Sorry boot. Hard boot. Wanted to kick it with a boot.
This went on for a week or two. I plug it in, no fast charge. I unplug and plug it back in, and it would work. Sometimes it didn't work at all.
Now it works again.
The last thing I did before it started working again was that I used a pocket juice 4000mah power brick.
I have a lot of different power bricks and maybe just maybe one of those messed up the mojo of my fast charging abilities. Moving forward I will only use my fast chargers and the pocket juice 4000 if I am going to use a power brick at all.
Why? Because now that fast charging works again, life is back to normal. 8-)
I did process of elimination trying to figure out how to fix the fast charger charging mystery problem. Now that it works again, surely I solved the problem.
Solution. Pocket Juice 4000mah charger plugged into my Samsung note 5 until pocket juice was down to one bar. After that, the fast charging started working again.
