This is absurd. I can't count how many times I had to do 1-4 more hours of work somewhere outside an office with my phone already being at 10-15%. Your device should have enough juice to help you go through an abnormal day as well.
Optimizing your life for inferior battery life is absurd.
My former work iPhone could last two days. I'll take that over strange justifications of awful idle battery life, any day.
Nowhere did I say that it’s because the phone doesn’t last. I was pointing out how having alarms work when the phone is off at night doesn’t matter anymore.
It's a nice way to make sure you won't get any notifications etc as well. I realise there are Do Not Disturb modes and so on though that achieve the same result.
