Samsung devices will not fast charge when device is in use until you lock the device. samsung added this as a extra safety feature so that battery won't explode of extra load. fast charging will make your battery overheat and on top of it if you keep your cpu/gpu on heavy load which will again overheat your battery and may explode. or may not explode or completely shutdown.
so if you want fast charging stop using your mobile while fast charging.
samsung fast charging works better when the device is powered off ( or) shut down.
you are absolutely wrong.....I am using galaxy s9...and it's charging fast when I am playing games or doing something also...but that is not procedure or recommended which I maintained before
I just wanna know is it possible to get fast charging while playing games on my Note 10+? If it is a hardware or software issues then I have to visit Service Center.
Please perform the below mentioned steps to resolve the issue:
1. Avoid usage of mobile phone during charging, Usage of the mobile phone when charging may cause slow charging issue.
