Ok, before i watch the video, no damage is not what great scott found from his testings.. ( https://youtu.be/iMn2yVoEqPs ).
so i have no idea what to believe anymore, but my (based) experience is that it does damage it. Ill have to watch later.
Yea, but that wasn't a great rest. I love Great Scott, but a lot of comments fairly call out his conclusion.
Most (all?)phones don't charge at full speed to 100% charge, they fast charge when the battery is almoast empty, and charge slower the more full it gets.
Right, so basically he removed the software aspect in his tests which removes systems to protect the battery. I assume without them, it is damaging, like what great scott found.
Ye, he should have continued his experiments then!
It's a true conclusion, though, although it's not real world applicable.
It is, if you are just dealing with bare batteries without any kind of protection, but if you are dealing with cellphones/modern smart devices, not so much
Those circuits he made up doesn't take into account that the phones have built in protections that alternate the input based on charge level.
