Magic fix for smart devices Rule

Be sure to follow the rule before you head out.
Rule: You must post before you leave.
I know keeping a battery at 100% is worse than 80% for li-ion batteries. That is not the discussion. OP specifically suggested a constant full charge/discharge cycle as an improvement over leaving the device plugged in, and I can't imagine that being better for the battery.
I guess what I was trying to say is that yeah, it probably would be better than keeping it fully charged. I wouldn’t let it dip below 20% though.
Lower is no problem. The damage is done by the high voltages and also temperature. Don't go below something like 2 V and you will be just fine.
Whilst going below 20% is definitely a lot less bad than going over 80%, it will have the longest life if you stick between those two.
No. Going as low as possible and staying as low as possible is the best for any lithium battery. Here a good source: Accubattery. Note how "battery University" is not a credible source, despite their name. Maybe they made people believe this in the first place.
And here a primary source for the most fragile LiPo cells. Look at figure 7. Even down to 1.2 V and the cells still reached 50 cycles until they were at 80 % remaining capacity. Not going below 2 V and it will be just fine.
