Dry human skin has a relatively high resistance to current flow, which is why that 12V battery won't hurt you. So, if your car battery specs were swapped to be 1000V@12A, it would kill you, even though it's wattage is the same. And you can use smaller wires for high voltage/low amperage to get the power (watts) you need.
You're confusing "high voltage" with "high voltage loss". Ohm's Law governs the loss of voltage across a resistance for a given current passing through it. Since the current is low, the voltage loss is correspondingly low. And by "voltage loss", you mean "voltage across the component".
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
Too high a voltage tends to cause a catastrophic breakdown of a transistor. Once you apply over-voltage stress and the transistor breaks down, the pin will show short circuit (usually to ground). If you catch it, or limit the fault current some how, this type of failure will not be visible outside of the IC.
When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.
