Hey MartinsBalula,
I understand that you are experiencing some charging issues with your iPhone. I have an article with some suggestions for resolving this issue, and it can be found below:
If you can’t charge your iPhone, iPad, or iPod touch - Apple Support
https://support.apple.com/en-us/HT203030
If you have to manipulate your charger in order to make it charge your phone, but you don’t have to manipulate it in order for it to charge your other devices, then it may be best to go ahead and contact Apple Support using the link at the bottom of the included article. If you have to manipulate your charger in order for it to charge any device, then this may be a charger or cable issue, and you may want to consider replacing your charger and/or cable. Take care, and thanks for visiting the Apple Support Communities.
Cheers,
Braden
