Galaxy A55 charging issue

[Washe]

Galaxy A55 has a major charging issue. I guess, in some units, specifically majority of the units have such problem that 25W adapter doesn't charge it as fast as it needs. Sometimes, it stops charging in a certain percentage. There is no super fast mode option in the battery settings. Whenever the 25W charger is connected, it shows fast charging, but within a while, it shifts to normal charging mode only. Galaxy A54, A53, A52 or any other series devices haven't such problem, then why with this model? 

I got to know, many users are facing it. Even some of my friends who have A55. 

Let me affirm that I am using the official type c to c 5A cable and 25W authorized adapter. I've been facing this issue since I bought this device 7 months ago. Don't know, why Samsung isn't focusing on this issue yet. I've complained many times, but no effectual response! 

Please, don't show the alert post. Apart from making us known to the cautions, please solve this lame issue. 

So-called premium A series!

I understand how frustrating this issue must be, especially when you've invested in a device expecting reliable performance. You're right—charging inconsistencies shouldn't be happening, especially when using an official 25W adapter and a 5A Type-C cable.

From what you've described, it seems like the Galaxy A55 might have a firmware issue affecting its charging behavior. If the device initially recognizes fast charging but then slows down or stops at certain percentages, the problem could be related to:

1. Software Optimization – The power management system might not be properly optimizing 25W charging.


2. Battery Protection Feature – Samsung devices sometimes limit charging speed to prevent overheating, but this shouldn't happen consistently at low temperatures.


3. Hardware Issue – A defective charging port or internal power management component might be affecting the charging process.



Possible Fixes & Workarounds:

1. Update Software – Ensure you're on the latest One UI version. Samsung may have silently addressed this in recent updates.


2. Check Battery Protection Settings – While there's no explicit "Super Fast Charging" toggle, ensure that "Protect Battery" isn’t enabled in Settings > Battery & Device Care > Battery.


3. Test in Safe Mode – Boot your phone in Safe Mode (press and hold Power > Long-press "Power Off" > Select "Safe Mode") and try charging. If the issue disappears, a third-party app might be interfering.


4. Use a Different 25W Charger – Even if your charger is official, test with another genuine 25W Samsung charger to rule out a charger-specific issue.


5. Reset Battery Calibration – Let your phone fully drain, charge it to 100% without interruption, and restart it.


6. Check USB Port & Cable – Even official cables can have defects. Try another high-quality Samsung 5A Type-C cable.



If the Issue Persists:

Since you've been facing this issue for 7 months, it's disappointing that Samsung hasn't issued an official fix yet. I strongly recommend visiting a Samsung service center to check for any hardware issues. If many A55 users are facing this, Samsung might acknowledge it in an upcoming update.

All are tried thoroughly before. But there is no result. I visited Samsung authorised service center last week. The technician said that it's a software issue. It can be fixed if the company wants. They have nothing to do as it's a software issue. Otherwise, hardware wise my A55 is fully fine.
