I have a Samsung Galaxy A51 which is stuck on the charging icon (lightning bolt). It shows no battery percentage. I tried replacing the battery and charging port but the problem remains the same. There is no liquid damage inside the device. Is there something I haven't thought off? Or is it a main board issue? I also tried force restarting the device with the volume - and power button

My approach would be: disconnect the battery and connect multimeter leads to the battery connector on the motherboard. Then, plug-in a charging cord and look for voltage (might not be continuous, could be pulses). If the motherboard is putting voltage to the battery connector, then you can assume that the issue is with the battery itself. If the motherboard is not putting voltage to the battery connector, then you may have a damaged PMIC, or a short circuit on the charging system.

If you have the 4g version have you tried replacing the flex cable from the charging port to the mainboard?

Thanks for your reply, forgot to mention it but I already tried it with a new main flex cable. Also tried getting in recovery or download mode but that also doesn't work.

I also have the A51 and the lightening bolt is there when the phone is showing 100% charged. It works all day on usually just one charge which I doi overnight with the phone turned off. I just switched out my charging cable to try to stay a step ahead but even with the old cable the phone was still charging to 100%.
