S8 not fast charging after update

Re: S8 not fast charging after update

Unfortunately, my phone has now run out of batter and will not charge.  

It is a very expensive brick at this point and I'm on-call for work next week. 

This ought to be interesting.

I'm having the same issue before I even updated my phone. It tells me to use the original charging cord that comes with my phone but thats all I use. Also, sometimes my phone glitches and randomly restarts while I'm using it.

Thanks for that info @userBAVWItLfXz  Since this forum was largely designed for US based devices and their owners, I'm afraid I have limited information on international devices. I can do basic troubleshooting but I feel as though your best bet for direct assistance would be to reach out to the Samsung Support in your region.

Re: S8 not fast charging after update

Fast cable charging not working on my galaxy S8 (Italy) since update yesterday (Italy). I bought the phone 1 month ago and have tried using the fast charging samsung adaptor from my old S7 edge to no avail so I'm guessing it's not the charger itself. It says that it now needs 5 + HOURS to recharge. I have done a factory reset, nothing, gone to fast cable charging, nothing, it tells me to unplug and then plug in the charger it then greys out obviously not recognizing that it's a fast charger. Is there a fix to this obvious software problem? I have bought every galaxy except the S5 and frankly I'm a little miffed that it's saturday night and I won't be able go out with my phone. Thank you. p.s. Samsung Italy technical assistance is useless.

Re: S8 not fast charging after update

my son's S8 also no longer fast charges after a recfent update. We do not have a wireless pad to try. his phone info is: Model: SM-G950U Carrier: AT&T Baseband: G950USQU2BQK5 For a long time after one of the updates, it would tell him that moisture was detected in the port even though the phone has not gotten wet. With the most recent update, that does not happen as much any more, but now does not fast charge. I believe he only gets the moisture message when the phone is dead and not powered on and then plugged it. He has to do a soft reset to clear the moisture message.

Re: S8 not fast charging after update

Updated my phone on the 27th and on the 28th when I started to  use it found it not fast charging any longer.  You can end the speculation on wether or not it is due to an update.  I've seen enough people saying the same thing.  Model number SM-G955U Baseband G955USQS2BQL1

 

I've owned the 4, 5 and 7 and have had my little complaints about all of them but this one puts me over the edge. If a fix isn't provided for this issue pronto then you've lost a Samsung user.

I had the same problem. Restart your phone into safe mode. When in safe mode plug your phone in. After that it started fast charging again. Turn off safe mode and done. Also check battery setting and make sure fast charge is enabled.

Re: S8 not fast charging after update

Similar issue. When using the charging adapter and cable that came with the phone, my phone only fast charges 20% of the time. I can often unplug and replug a handful of times to get it to recognize and fast charge, but the fast charge will often drop to 'cable charging' after a few minutes. Really inconvenient and not what I signed up for.
