“Something that’s not an issue is overcharging. Contrary to what you might think (or have been told), leaving your phone or laptop plugged in all the time is not bad for its battery. That’s because your gadgets, the batteries in them, and the chargers you attach them to are actually pretty smart about the way they do business. Trickle charge—what your battery gets when it’s connected and full—is way less detrimental to the battery’s health than a larger discharge would be.”
Like with almost everything in life, once you take the time to learn more about it, you realise everything you thought you knew was wrong.
