LG G2 on CM 12 battery problem

[AC Question]

So guys,I like to play along with my LG G2 system.I replaced my battery with a new one and everything was fine.Yesterday I was going throuh some root progfams in the Play Store.The one i downloaded was ROM Toolbox lite.I used it to install a font on my phone.When I uninstalled the toolbox the problem came.When i plug in my phone into a charger,(u know the light that shows you are charging)the light keeps blinking(charging,not charging,charging,not charging).When it is turned on i dont have that problem,i mean it charges normally without this blinking,but I cant stay for like 3 hours with the phone waiting for it to charge.So if someone has the same problem and has fixed it somehow,Id really appreciate your help!!!
