And also when I try to connect the phone to the PC it start charging for 5 seconds and then it shows the notification "not charging" and the battery symbol in status area show that it's not charging the led also shows the same thing. But the weird thing is that in status menu in the battery's bar there's written "charging" Edit: BTW the reason why I think it is a problem resulted from kernel power 50 is that when I try to charge my phone by connecting it to the PC- Motherboard's built-in USB ports it charges well.
