You can control the battery % at which a device will begin and stop charging - so there's no need for this. Idk what all this misinformation is about.

- kachnuv_ocasek 11y agoSure, but the battery gets heated when left plugged in, which is not good for its health.
- hurin 11y agoWhy would the battery be heated if it's not charging? You can set a gap - e.g. 80-100% where the battery won't start charging until it drops below 80%. Look at the documentation for your relevant power-management module.
- qbrass 11y ago>Why would the battery be heated if it's not charging? Heat transfer from the device it's plugged into.
- hurin 11y agoI'm not a hardware/electronics guy, but I'm rather skeptical that this is any kind of notable amount - do you have a reference?
- sokoloff 11y agoPut the back of your hand (or your bare leg skin) against a laptop that's been in use. My Macbook is noticeably warm (maybe 15*F delta) in normal, non-charging, operation. That's with the benefit of conduction to the free air; I assume the inside delta-T is higher.
- hurin 11y agoThat's not answering my skepticism to GGP's post - what he is saying is: a non-charging plugged in device has a significantly hotter battery than a non-plugged in device because of thermal-conduction across a non-charging wire?
