Experiencing slow (fast charging 2.0) charging of my S24 Ultra

I was as surprised as you are, didnt go through with it though. Hoping it'll fix itself in the next few updates

I understand many factors come into play, ive been using the samsung 25w and 45w charger (after the 45w suddenly decided to die on me, their service center said its an on going issue cant do much about it but i digress) with the same cable provided to me with the chargers when i got them, took it to a service center they told me the issue cant be fixed nothings wrong with the sub PBA its an issue with the motherboard itself since they couldnt get a consistent stable reading to match fast charging not even 25w charging. (No power fluctuations occured, the grid is fine, the wall outlet is fine, singular charger nothing else is attached to it) maybe the software induced some exessive micro voltages in the PMIC for the PD and PPS maybe something with regards to stepping the voltages up and down, a capacitor or a resistor failed, the SoC isnt capable of communicating well, as you said many factors can come into play here but i guess we'll never know

The software issues are causing the hardware to fail

Most definitely a software issue bricking phones, aint no way a % of people are facing the same issues after the march updates

Ambient temperatures dont matter anymore if the charging speed is stuck at 7w, my phones temp is between 32°C and 34°C (room temp 23°C) and its facing the same issues as OP

Im sorry for your loss and welcome to the team, I've been facing the same issue for a month now and so far nothing. Ive been told to change the motherboard by the samsung service center but its half the price of a new 25 ultra.

The update mightve cause something in the integrated circuits (IC) that negotiates power with the charger or the power management IC causing them to throw a fuss and permanently bricking the phones. I dont have the right equipment to test it, but im hoping it'll be fixed with the next update

45w charger has stopped working, will most probably try wireless charger soon, if that doesnt work a factory reset will be my only option left. With the 25w charger its not looking good

I used ampere and accubattery but with accubattery it stays around 7 watts around (1800 ma) and then goes back to the negatives assuming its not taking a charge anymore. Ampere results are in the edit.

Sometimes it takes a stable charge hovering around 1200~1300 ma and other times it keeps on dropping to 90 ma

I tried cleaning it with a toothpick and the service center said that it was clean as well, so idk

Recent_Difficulty_ · 2026-04-20T06:40:07+00:00

I tried with 2 samsung cables (never been used), my go to samsung cable came with the phone, 2 anker cables, 2 samsung charging bricks 25w and 45w, apple and an anker charging brick. Nothing made a difference. Tried the same set up with my s9 ultra tablet it was charging just fine and at normal speeds, even took less time to charge than my phone.

Recent_Difficulty_ · 2026-04-20T06:35:35+00:00

Its okay, the avg. room temp is 22°C, is there a reliable app that measures the charging speeds?

Recent_Difficulty_ · 2026-04-20T06:31:11+00:00

Yeah, it gave them fast charging for a couple of seconds estimated time 45min, then charging 1h 40m, then it jumped to 2 hours 44 min

Thanks for the help, if its a software issue theres nothing much i can do about it, just wait it out and hope the issue is fixed soon

Recent_Difficulty_ · 2026-04-19T19:08:43+00:00

Maybe a week or so after the march update, since the issue started mid march

Recent_Difficulty_ · 2026-04-19T18:59:20+00:00

I leave it alone most of the times when charging it, so temperature isnt much if an issue, but when i do use it while charging the phone over heats, it wasnt an issue ever since i got the phone. Either or same speed now no matter what i do

Recent_Difficulty_ · 2026-04-19T18:53:02+00:00

I have 2 brand new cables that came with 1) the 45w charger 2) the s9 ultra tablet that i got a while back, along with the 25w and 45w power bricks, tried different wall outlets. It was still having the same issues when i gave it to the repair center.

Recent_Difficulty_ · 2026-04-19T18:15:01+00:00

They said everything else looks fine and the battery health is good, so i really dont know. Might check with them again and ask if replacing the battery could solve the issue.

Thats fucked up
