Fast Charging not working on Note 10+ after update to Android 12 (one UI 4)

[ronenbu]

After the latest update rolled out a few days ago (Android 12) for my Note 10+, Fast charging stopped working. used various power adapters (original from Samsung, and others) which worked perfectly fine before the update, with no avail. Tried restarting the phone several times, switching cables and adapters, turning fast charging on and off in the battery settings, nothing helps. I saw that there is similar comments on the S21 after the latest update, so has to be a common issue?

With high wattage adapter, it does says fast charging, but gives a 3 hours estimate to fully charge a 56% battery, which is absurd, as its not fast charging. with the original OEM adapter (fast charger) it doesn't even says its fast charging. so the issue might be related to software limiting something on the charging process..

This renders the phone almost useless, as the battery needs to be charged at least once during the day now.. Anyone else seeing this?

Mine takes around 4 hours or 5hrs for getting fully charged after the update. No response and bug fixing update from Samsung till now.

Yes this is definitely an update software problem, literally my phone for a year and a half has never had a problem fast charging until the latest update a few days ago. I have went through five obvious steps of seeing which it could be and all of them have left me frustrated as hell because none of them have worked! We need a new update asap

Same issue here, Spain. My Note 10 lite lost the fast charge with last update.

Really, this is not a loss... but a robbery.

My last samsung device if they don't step back and fix the issue.

I delayed the update for as long as I could until 2024 when I accidentally tapped on the wrong button and find myself also having this issue. Troubleshooting completed: I have ensured all my apps are updated by going to the Google Play store and checking for app updates. I have also cleared cache and cookies. The phone was also restarted after the first two steps were taken.

When the fast charger was plugged in, it seemed promising at first but then it stopped charging and kept switching back and forth between fast charge and no charge at all. The only thing I can use is a slow charging cable and adaptor but takes over 6 hours to reach a full charge. Please advise!
