I expect low data rate because the distance will fall back to a lower coding rate.

I observe a difference in my phone’s batter life between urban and rural usage. I expect the battery life to be significantly reduced with Starlink.
And yes… if the phone isn’t communicating then the battery life isn’t drawn down much…
But users with high screen times will have to change their habits.
— avoid receiving text messages (not under the user’s control)
— don’t receive email pushes
— stop all the social media updates, messages, and likes.
— turn off the apps
— only use the phone for emergencies.

Who are the intended users?
