I am addicted to my mobile phone/smartphone.

English Teacher
I am trying to suggest that my mobile phone has become a part of my body as I am heavily dependent on it.
I need an interesting and amusing way of expressing this idea.
Examples:
-I am glued to my phone 24/7
-My cellphone is an extension of my body
But I think there should be a better and more interesting way of expressing the idea.
I am addicted to my mobile phone/smartphone.
I am not a teacher or a native speaker.
Thanks for your contribution.
I appreciate other suggestions.
The thread title is actually a good way of expressing the idea.
Other options include:
I'm lost without my phone.
Losing my phone is like losing an arm/leg.
I can't live without my phone.
I'm sure there are many more.
Wear short sleeves! Support your right to bare arms!
Is this correct? :
-I am glued to my phone 24/7
I still think there are more creative ways of expressing the idea.
Wear short sleeves! Support your right to bare arms!
"My phone is a part of me" is short and sweet and sums it up. (My opinion.)
