Battery Charge speed variations

[tech_fan]

I normally charge my phone while I sleep. On occasion I noticed that the battery still shows that its almost charged when I wake up which is not a big deal since when I get out of the shower it is fully charged. Today, when I woke up I see that the battery showed 59% charged and it needed another 2 hours to fully charge.

This time around I thought it was odd. I have a Samsung Wireless Charging Pad, Anker wireless charging pad and a 15W USB-C charger. I have tried to restart the phone and place it on all 3 chargers and they all state that it needs another 2 hours to charge. The only thing I can think of, is that I put it on developer mode last night which I turned off this morning and that did not change anything.

Is this some kind of AI thing which it charges slowly on certain days and not others? Anyone else run into this?

I have the Samsung dual wireless pad (one side Watch 4, other side phone) and both my Flip 3 and my S21 Plus do the same thing. I have no idea why and I've given up trying to figure it out. If I plug directly into the USB plug it never happens.

Interesting. Thanks for letting me know. Now I remember the same thing happened with my S21 Ultra and I could not figure it out either. Maybe it is something with the dual wireless pad as that is what we have in common? When I had the trio I do not recall this happening or not being this bad off.
