Tone while charging???

[jsbcarman]

Proud owner of note5 , awesome device, I have noticed this quirk , when charging phone (not with supplied fast charge cable) using non original charger it is still pretty fast but when it gets to 97% it beeps every 5 seconds or so and screen will light up at that time, it is the same tone you might hear when just plugging it in to charge but thats just a one time thing with any charger. anyone else getting this and want to share how to make it stop?

I charge mine at night on a Spigen wireless charger (works great) and it will do the same thing, and it's sooooooo random. Some nights it will go all night without making a peep, some nights it will do it all night long, some nights once or twice... Just a weird thing, I guess.
