How long do you stay online a day?

I can stay online up to 15 hours it depends on my mood. Actually I stay online its because I have to communicate with my love ones who are far from me, and the time zone here and there is different so I have to stay online until midnight just to talk to my love ones out there.

 

I spend almost half a day, that is 10-12 hours a day on my phone. This is because as an online tutor I have to keep connecting with learners online every hour between 7am and 6pm.
Most of the time I am online sending notes to learners, answering questions,going through online submitted tests or researching on new topics.
At times I am online going through attachments send to my email or whatsapp account which mainly include; assignments, answered questions or course notes
