I believe that, because Apple does not explicitly mention this anywhere in their physical documentation (to my memory), many users immediately (though unintentionally) mistreat their batteries by not fully charging them out of the box. Afterward, they'll also sleep it for long periods (instead of shutting it down). Finally, users generally don't run from 100 to 0% (even less often than once a month) like Apple recommends.
I think Apple should be a little more proactive in getting people to read that page I linked (and the device-specific pages on it).
Apple's battery page basically details why Li-On is the best choice for mobile devices. The only real instruction they give is to use it once a month - the rest of the page describes how Li-On is pretty maintenance-free (which is true). Same with the iPhone battery page.
Not charging it fully out of the box has a minimal impact on the battery over its lifetime.
Letting phones sleep for long periods isn't an issue - Apple designed their portable devices to sleep instead of shut down. This is normal behavior and does not cause issues (except perhaps leading to more cycle counts if the iPhone isn't plugged in).
Running a Li-On battery from 100 to 0% is actually harmful to the battery. Regularly running a battery that low creates unbalanced cells and leads to early performance issues. The only reason Apple (and every other manufacturer) advise this is to make sure users use the battery at least once a month (not an issue in this discussion) and recalibrate the battery percentage indicator. Not going from 100-0% has minimal negative impact on the battery performance, unless you never use the battery.
I believe you are wrong to say that most iPhone users maintain their batteries incorrectly or poorly. Li-On batteries are very maintenance-free. They do have finite charge cycle counts and become adversely affected by temperature changes, but otherwise a regular iPhone user should not encounter a user-caused battery performance issue on a new iPhone.
If you are arguing that users use the battery incorrectly by not turning down screen brightness, turning off features, etc., then we just have a difference of opinion. People should be able to use their phones at the default settings and not experience issues (which is normally the case for the iPhone, unlike Android). If an issue crops up - like with the 6.1 update - it is likely Apple's fault and not that of the user.
