The question is simple. Does charging protection (limiting to 80% charge) make a difference in battery lifespan?
My logic dictates that Li-Ion and Li-Po batteries are designed to operate at a specific voltage, which correlates to 100% charge. If it wasn't safe, then manufacturers wouldn't designate that voltage as 100%, they would set something lower. I might be wrong, though, as I imagine, it's not entirely impossible to overcharge a battery. The question is, do we actually overcharge our batteries at 100%? Does limiting charge to 80% actually extend battery lifespan? Is there any research in the topic? Or are phone manufacturers catering to our conspiracy theories on planned obsolescence by letting us limit charge to 80%?
