After udating june security patch, whenever I charging my phone not showing the rapid charging and also battery draining of very fast.
They disabled fast charging when the screen is on (e.g: you are using it) to prevent excessive heat damaging you. If you charge it with the screen turned off and then turn it on you will see for a brief moment that it was quick charging.
As for the battery draining I recommend you check the display brightness cause it's been very bad for me lately, it constantly set it to unnecessarily high values.
