Comment on Why Charging Your Gadgets Over 80% Is Such a Bad Idea | iFixit News
Static_Rocket@lemmy.world 8 months agoYep. Battery chemistry is a real pain in the ass. Every few years someone spins a wheel and determines the next big thing that everyone needs to do to prevent batteries from dying early. For a while people were told full cycles were healthy for avoiding cell memory. Now more sporadic cycles are being peddled.
Use the device as you need it. If you complete a full cycle, cool; if not, that’s fine. Just don’t let the damn thing completely die and don’t keep it permanently on charge. Those are the common things most people do on accident that can really screw up a cell.

It isn’t spinning a wheel though, the advice hasn’t changed in decades (I’ve written something like the above comment at least a dozen times on Reddit since 2008 when I worked in the industry). Rather you might be getting it confused with other cell chemistries. Memory is a problem for NiCd cells, which were popular a long time ago, but even once we moved to NiMH for most things and then Li-ion there is no concern about it. Unfortunately there is a ton of incorrect and bad information out there about batteries so it is hard to wade through the crap and find the real information.
batteryuniversity.com is the best resource I know for correct information about li-ion cells, since it is written and maintained by a company that designs battery testing equipment.

Part of the problem is the game of telephone drops the cell chemistry related to the method almost immediately leading to general consumers applying it as a blanket rule for all batteries
