Xperia 10 iii slow charging

[RobSyr]

Howdy, 

yesterday my 6 month old Xperia 10 iii would not start charging (tried original and different charger). There was no notification of the port being wet or dirty. I left the phone shut down overnight, tried charging it in the morning and it surprisingly works.

However the charging is super slow with the original charger (10 % in one hour). 

What could possibly be causing this and can it be fixed or do i have to send it for replacement,

Note that i had the phone for 6 months, always keep the battery between 20 and 90 % and there are no extreme weather conditions where i live.

If you are implying that this feature was the culprit of my problems that simply cannot be the case.

Basically since i got the phone i always used the option "always charge to 90 %".

Also it wouldn't explain that there was no indication of cable connection and it didn't charge at 50 %.

I personally use battery care automatic option only.
But have You tried restart phone in safe mode or charge with the other cable or check that the charging port is clear of dirt etc?
