Try to use phone until you left less than 10%, then left it to charge to full in SFC mode, see if full or not

Me too.

Finally get to test below 10% and SFC not charging.

However with only Fast Charging, it's fine.

I'll test more scenario with SFC and FC

Here's an article from Sammy fans.

I notice that it's a hit and miss. After I disable the fast charging, I charge from below 10 to 20% normal. Then I was curious and switch it back on Fast Charging. From 2x% charges all the way to 100%.

I still need to verify again by repeating the steps.

I tried charging from below 10% all the way to 100% , it doesn't increase. It does show SFC but the percentage of battery isn't increasing.

UPDATES

The first 2 mins when I plugged in showing SFC, battery percentage from 45% didn't increased.
So I unplugged the cable and plug in again, 2 mins later, with SFC and it charges to 60%.

That's the workaround I found as of now.
If this method works for you, let me know.

A bit troublesome to plug and unplug, but sometimes having SFC helps in a pinch.

The problem is either these 2:
1)SFC not working altogether
2)SFC working but as Keatsan said charge up to certain percentage and battery charge percentage stops increasing

How to lock band?

Dial *#2263#

Correct. max 60% only.... have to change back Fast not super fast now.. demn

That's why I always wait like at least 2 weeks before actually updating

Apparently September patch fix these bugs

Is SFC issue resolved based on your testing?

As of update, SFC can charge my phone from 10% all the way to 100%.

So far so good.

Still 0 update after 64 days
