Don't know where to post this. Apologize if in wrong section.

My Samsung S8+ will charge very quickly if i don't use the phone during charging. Once i use it to reply some message and leave it there again, it will goes to slow charging.

I need to plug out and re-plug it for fast charging again.

Anyone know what causes this ?

Thanks.

does your phone run hot? have you tried using other cable? original cable is not so reliable as some of the pin will wear off sometime resulting in poor contact and slow charging

beware of motherboard issue... may caused slow charging if its faulty... better get it check before warranty runs out

I kena before for my note 5...motherboard and charging port spoiled...

I always charge overnight and maybe this cause it spoiled....

now I use Huawei and it working well....

Hmm, may take note on the motherboard issue. But let me try to get another charger and do the same see if i face same problem.

Will update again.

It's charger issue XD
