Just checked my laptop uptime and it's been on one charge for exactly 1 month, with average use and aggressive tlp/powertop settings 😰

    @Floydian I think he means it's been plugged in for a month without draining the battery before plugging it back in.

    That's how I understand it, at least.

    @Floydian @Stuxnet I charged it exactly 1 month ago and since then it has been unplugged and exclusively on battery

    @JoshBent what the fuck battery is in your laptop and how often do you use the laptop?

    @Stuxnet asus e200ha with antergos tlp and powertop, have been using it 4 times a week, for ~2/3 hours each, have been mostly in vscode, terminal and chrome

    @Floydian yes 🤣

    Wtf? My first ever laptop lasts 3 hours when only writing a document lol

    Prob someone is charging it without you knowing.
    If not then I want some of those uranium batteries 😎

    @RantSomeWhere @WinterCore @Floydian @1989 @CozyPlanes haha love what this turned into 🤣

    @Floydian There is no requirement for "if". Everyone know what you mean :)

    Yeah, nah. Either you have consumed those batteries down to full death, or something doesn't add up.

    If it's the former, I'd keep a fire extinguisher handy next time you plug it in. (Seriously though, lithium fires are nasty - and make sure you do NOT use water, CO2 is recommended)

    @endor It was at 4% when I checked, also it's not uncommon for those low power machines to last, though a month is very impressive, though the capacity is at 90% already, so something is wrong for sure 🤣

    @JoshBent careful, make sure it's not puffing up or overheating. Lithium batteries have a very peculiar behaviour when they are discharged too much, they're not 'linear' like people expect them to be.

    If the voltage of any of the cells has gone below 3.0V, I'd suggest changing the battery (or at least, reading up how to handle it without risking any fires)

    @endor not sure any controller reports per cell health nowadays anymore anyway, but I doubt itll explode, all itll do is expand and smoke if actually theres no drain protection circuit (which is standard and cheap as shit)

    @JoshBent it's not the surge in this case: when you recharge (at the normal rate) a lipo that has gone below 3V, some chemical reactions start to occur, and it will puff and warm up significantly.
    When you have such a battery, you have to recharge it *veeery* slowly (think <0.05A), otherwise your battery will lose capacity and lifespan significantly (assuming it doesn't overheat and die before that)

    @endor @condor correct me if I'm wrong, but the point of that protection in batteries is so they don't go below that bare minimum, where all that wonky stuff starts to happen

    I think you're thinking of fully self managed cells, I don't think a battery in a laptop would even pass anymore, if it doesn't have under/over-charge protection and also it would just shutdown

    To quote the video: "Never blindly trust the seller". (In the part that I linked, the guy tests the overdischarge protection of a lipo, and it fails to meet the specs by a massive amount)

    Can confirm what @Condor says: lithium batteries are among the best technologies out there nowadays, but they are massive divas to work with - make a mistake, and they won't forgive you

    @Floydian Reported you.

    @CozyPlanes In case you did, don't take it serious (dfox won't either), his joke was indicated by the "tch tch" and "bad boy"
