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?

Hi,
Update your phone apps

Clear your phone cache

Since your phone is running on the latest software update some of your apps might not be optimized to run on this new version yet. This might cause issues such as the slow charging problem you are experiencing. Try to update your phone apps then check if the issue gets fixed
Also run the galaxy app booster

Can we have something better than a default answer, please? I have the same problem, right after updating my Galaxy Note 10+ to Android 12, One UI 4.0. Fast charging via cable works, fast wireless charging - doesn't. Charges not-fast way, shows "3hr until charged".

It always worked, it's turned on in settings, the wireless pad and the adapter are original and were shipped with this phone. No pending app updates, even though I don't think this might affect charging. Phone is not hot, when I place it on the charger. Removing the case didn't help either (always worked with the case on).

It's a clearly software issue caused by update!

Even I am facing the same problem with both wireless and cable charging since the One Ui 4.0 and 4.1 update.

Hi. Did you sort the issue? I usually don't update the phone straight away, kept it for a month this time also. Updated now and got same issue... Phone doesn't recognise the super fast charger at all, does fast charge with same cable off another charger...

Same thing.  Phone plugged in for 7 hours and only got to 85%.

Battery drain is vastly accelerated during normal use.

Is this Samsungs way of forcing to to the 22 ultra?  Seems like it.

How many users are eligible for an upgrade????  Plan obsolescence.... 🤔

Tired of doing all this steps. These are one of the basic steps that we do in the first place.. but it's of no use.

I have a Note 10 Lite. I installed this system software update to my phone and it keeps restarting continuously when connected to a fast charger. Simply Terrible!! Is anyone else seeing a similar issue?
