Possibly faulty motherboard - Discussion

My Xperia M2 is dying. When I leave it plugged in the wall charger overnight, it doesn't charge at all, after several time. This is, right now, resulting in a cool plug-unplug effect in the device, and even when the USB cable is disconnected, *the device still thinks it's connected to the power source*.

Another symptom that something was going really bad is that yesterday, my SIM card was being rejected by my device without any apparent reason, unless I rebooted my device, in which case it started working again, just fine. After happening 4 times in a row in a single day, I ejected the SIM card, cleaned it, and place it back. It didn't happen anymore, but could happen again.

Environment:
Almost 2 years old device, with unlocked bootloader. Model D2303, Revision 4, with XPERIA Z5 STYLE 4.6 installed on it. Device hadn't been *wiped* since 4 months now.

Now you'll be asking, why creating a thread?
I don't want to mix any development thread with a possibly hardware fault, and I still want to hear your opinions and thoughts about this situation, mostly if it has happened to you at any time. Right now, I'm doing some tests, and if it still happens I'm going to send my device back to Sony Mobile Spain, hoping they can fix it under warranty.

Any ideas of what can be the problem? Please comment them down below.
