Is anyone experiencing charging issues.. the last two nights I've had my phone charging from 11pm to till 5am and both days I've woke up and it's only on 56% charged? (Says Super Charging is working but just doesn't go past 56%) 
 
 Confused.. Any ideas?

Get the battery level down to zero before recharging. The battery can sometimes lose its 'memory'
Hope this works'

That was only applicable to older batteries. Never drain 0%. Just hold power and volume down to phone turns off. It's a force restart then charge.

I have an SM-G998U Ultra 5G and fortunately no issues charging.  I bought an aftermarket wireless charger and every other night I lay it down with between 10 & 20%, and have full charge by morning.

My S21 Ultra is taking 1.5 hours to charge from 5-100% with the Samsung 25W super fast charger and the cable supplied with the S21 Ultra.

And I have fast charging and super fast charging enabled on my device.

Any idea what I may be doing wrong?

I'm having the exact same issue with getting stuck at 56%. Did you ever figure it out?

I'm just done what @Tommo56 said I let it run down to 0% let the phone die so it resets the battery memory, haven't had a problem since doing that. Hope this help 👍🏼

I just had the same problem. Samsung ultra S21 from 2021 the charger does not come with the phone. I purchased a cheap charger, it took 10 hours. I went to Samsung site and purchased the original for $29 it just arrived. The charger is now superfast. Samsung have designed it this way.
