Charging Problem

[joelyakob]

Got the new s25 ultra, pretty decent gadget. But im facing a charging issue, like the moment I plug the cable it would charge and the next second it wont, it keeps on jumping from charging and not charging. I thought it was with my phones port, but after restarting the phone the problem resolves. It seems like I have to restart my device everytime I decide to charge it. Is there any permananent solution to this ?

My issue was fixed by factory reset, the ampage on the device while fast charging is very low it's odd, around 1600ma then when it gets to the end and is slower, it goes up to 3700. However when I set up the phone again, I didn't use smart switch. I believe smart switch is bad. Smart Switch took me 9 hours to setup my device. I ended up factory resetting it and setting it up manually and it took less than 2 hours. However it's still downloading my onedrive library which is around 12,000 pictures so it's doing pretty well tbh. When I charged it after using smart switch, it took 1 hour and 10. minutes. This is acceptable for me as it was the same with my 24 ultra. also it's still learning my patterns which should take a couple of weeks however the battery has been pretty darn good.

I have the same issue. With my new s25 ultra I bought a genuine samsung 45w with cable. Plug it in and it says charging then not and keeps doing that. With non genuine chargers plugged it it'll take 3hrs plus to grt from 30% to full. 

Have restarted it and its now charging. Hopefully it's a one off and don't need to restart every time you want to charge

I have the exact same issue with my S25 Plus. First two charging cycles worked fine. The issue began from the third cycle.

With the 5A cable that came with the 45W charger, the phone goes into loop of charging and not charging.

But with the cable that came with the phone, it charges but not sure if is actually fast charging. When I plugin the charger, it shows this Now Bar charging animation and also says Super fast charging 2.0 only for a few seconds. Then, both, the animation and Super fast charging 2.0 disappear. Just the battery percentage remain thereafter. Is that normal.? I was expecting them to be there the whole time when the charger is plugged in, at least the animation.

The same is happening to me, and now, the 45W charger is not working at all. My S25 Ultra is not even detecting it anymore, and my S10+ tab starts charging but warns of slow charging and incompatible power brick, irrespective of the cable I use.

It looks like the problem has been resolved. I contacted Samsung via WhatsApp and received the following instructions:

1. Open the Phone app, enter the code *#9900#, and select delete dumpstate logcat -> OK -> debug level disabled low -> HIGH.
2. Additionally, check if the phone can charge when completely turned off. You can also try using a different cable or rotating the plug 180° around its axis.
3. Another helpful step is clearing the app data. To do this, go to: Settings -> Apps -> Click the filter icon next to "Your Apps" -> Show system apps -> OK -> UsbSettings -> Force Stop -> Storage -> Clear Data.
I followed all these steps. I actually started with the last step and finished with the first one. Additionally, after completing the first step, the phone restarted itself. I also performed an extra reset.

For now, after plugging in a 45W charger with a 5A cable, everything seems to be working fine. Let me know if it worked for you!

I have the samsung s25, been fine and now when I go to charge it, it's giving me a warning it's detected moisture inside. The phone has charged fine for the last week I have had it. Now won't charge at all.

I have seen a few issues between chargers and phones and it seems to mainly happen with chargers that when they change their charging mode (inc voltage) they briefly cut off from the old mode to zero and start again in the new mode. This seems to throw some devices.

On the S25U mine will only charge at 40W+ when the battery is below 20%, by 50% it will charge below 30W, by 90% it is under 20W, by 95% under 10W and gradually dropping off as the battery becomes fully charged.

On a fast/Qi2 wireless charger it will charge at a charger input of 20W when the battery is down which is probably a charging rate to the phone of 15W.

More on my saga, but my Fast Charger is charging faster than the super fast charger 2. I can be at 29% and it will take 1 hour and 11 minutes (accurate as I timed it). I can be at 49% and it will take 50 minutes to charge to full on super fast charging. I still have to send in my unit to be checked though.

hi i had the same issue with my s25 ultra. extremely slow charging. takes 60 mts to charge additional 30%. but once charged, the battery lasts long. 
however i have to return the phone and ask for replacement. i cannot survive the 2 hours it would take to charge the phone from 30%. even my old note10 charges much faster after 5 yrs of use !!!
other than that, s25 ultra is great typical samsung quality.

tried everything. i have been using samsung for 10 yrs. this one is the slowest charging phone ever. so i have asked for replacement.
