I don't think grounding or taking away electronics works that well. Also, i think parents nowadays just have a "Give me your phone" type instinct to take the phone or electronics away when they get mad.
I think there needs to be a more thoughtful approach. First of all, WHAT are you fighting about with your teen? Take a look at the actual issue and what is related to it. I learned that at times I was just dismissive and flippant towards their thoughts, feelings, desires, with, DO THIS or DO THAT. And, I learned to take a big deep breath when the conflict happens and found that if I responded to them in a softer way that actually conversations ensued and things got resolved. My instinct was to throw down as the Big Bad Parent. And I did that more with my oldest son. I started listening more.. I started just letting them have their VENT moment and then just go give them a hug. And you know what, fighting back with you is a GOOD thing. You want your child to be able to hold their own and stand up for him or herself. As I took at a less combative approach, then the drama from their end diminished greatly as well. Teens especially just want to feel that you HEAR them. Try actually agreeing and taking their point of view. Try admitting when you are wrong as well. It's a two way street.
