Don't phones already do this? (IE: 100% is not really 100%, 0% is not really 0%.)
I don't see it as cheating, it's akin to the practical limit vs. the actual limit
- sandworm101 7y agoThey do, but they don't claim this as any sort of advancement of battery technology. It's batteries 101.
- zeta0134 7y agoMany laptops do it too. Lenovo even markets it as a visible (and annoying) power management feature. Most however simply handle the charge cycles behind the scenes, and adjust their definition of "100%" over time, so the user can remain blissfully unaware (and less likely to change the setting). I don't mind this really. Batteries degrade over time; that's kinda just how they work, and I'd much rather have 100% mean "my device is done charging" and 0% mean "my device can no longer run." The specifics of what voltage or charge level or whatever actually translates to those numbers is not important, and honestly the battery / laptop manufacturer probably knows the right settings for those better than I ever will, so it's fine.

I'm travelling this week with my Macbook, but it's been docked for the past couple months at 100% charge. Would be better for the battery if I could keep it at 60% charge until I plan on travelling.
