Capping the charge at something like 60% is a great way to preserve the battery if you're not going to need all that battery life.
Storing at 40%-60% elongates the life compared to 100% or 0%.
All of this is 2nd hand, and I have no particular expertise to validate this comment.
- Udo 13y agoI don't understand. So with this setting people are artificially limiting their battery capacity to 40%, in order to preserve capacity they're not going to use? Meanwhile you'd have to ride a battery pretty hard to grind it down to 40% health, it'd take many years probably. I'm not sure what the average lifetime of a laptop is, but I'd be surprised if it's more than 8 years. What's the upside if the battery is well preserved at the time when the device is being replaced? Let's say with normal usage the battery will perform at an average of 80% over its lifetime, that's still better than 40% - for the same money.
