Yes it will. Increase in processor performance and device temperature also& decrese device life, better if it is in default dpi that comes with device( if you are playing games you need smooth gameplay then you change dpi)
Actually it is not displaying time also like " 1hour until full" etc, & when i turned off fast charging - in noraml charging it displaying time like 2hr 30min until full
