@n1vgabay read the answer I wrote in this thread where someone asked the same question about the XPS 13 9360. Yes, limiting max charge to 80% and setting minimum charge to around 20-50% is a good way to increase the long-term lifespan of your battery, but of course it means that it will be less convenient to use on a day to day basis. That's the tradeoff.
Thanks for your reply mate. How do I change BIOS settings carefully to set up this configuration? What actually "Dell Power Management" do? ("Primarily AC Use" mode).
DELL-Alan D, in Dell's website it saying that this method of charging/discharging it's not relevant anymore in the 'new' batteries which I'm assuming I have one of those.
Please keep sharing all the information you have. Very helpful.
@n1vgabay that is correct. @jphughan discusses the different chemical make up of the batteries in his referenced post explaining in more detail what the article mentions.
Can I rely on this dell's power management feature at home?
