Get a knife and remove 20% of the battery.

Percentages don't even exist in batteries. Only voltage. The percent just represents the voltage level between two extremes of acceptable voltage.

If you want you phone, laptop, car, or other device's battery to last longer, keep it at full charge as often as you can.

This is also very wrong for lipos! Please dont spill your bullshit here! This is only true for nimh not for lithium-polymer batteries
