• I would like the battery to last longer, without having to follow a BMMF usage model.

    Hypothetical BMMF usage model. I have the screen on full brightness all the time, and no auto-sleeping, because that's just common sense when it's in my pocket, or I'm busy doing something where I don't want to be/shouldn't be disturbed, or I'm asleep. GPS and wi-fi and mobile data are on at all times, because you just can't have too much of a good thing, and I have to log all my walking around the UCL campus on Strava, or else my VO2 Max will surely decline.
