Do people spend too much time on their phones?

Yes they do. Constantly walking into you as not observant.

But yes I spend a bit too much time on my phone, mainly watching TikTok

Absolutely, and it's a difficult habit to break.

I took a step quite recently in reducing my "mindless scrolling" by coming off Facebook again. It was largely AI generated rubbish anyway.

That being said, I'm probably still on my phone perhaps more than I really want to be.

I couldn’t give a universal answer because every person is different; I know some people who do and others who don’t, so it really depends on the individual. I couldn’t generalize by saying that everyone spends a lot of time on their phone, because that would clearly be untrue.
