An open letter to Tim Cook (You’re fucking up)

I'm a bit curious about the battery thing. I have no problem plugging in my phone every night, simply because I expect to do so. It become very routine.

I also have a Microsoft Band, where the battery lasts about 2.5-3 days. It's always running out of juice when I don't want it to. Why? Because I don't pay attention to it and it doesn't become part of a routine. I don't have a 'I will charge my watch on Wednesday and Saturday' setting in my brain. I do have a 'I sit at my desk in the morning, I don't need my watch for 20 minutes, I'll charge it' setting, but I don't use that one because the watch doesn't need me too.

I wonder if there is a human factor design in having batteries last just long enough that they match a personal rhythm.
