    Did anything change? Is this the same system/install which used to last
    4 hours on idle? Or, when you say "brand new bought one year before",
    you mean it wasn't used before?

    Battery life can change over time. I've had batteries that after a couple of years just didn't last as long. I've purchased a few replacement batteries
    from Amazon and one of them didn't hold charge at all.

    1 year is pretty short but possibly he might buy a new battery as
    a test. They generally aren't overly expensive.

    Or how about booting just to a console and testing how long
    the machine stays up?

    Battery life can change over time. I've had batteries that after a couple of years just didn't last as long. I've purchased a few replacement batteries from Amazon and one of them didn't hold charge at all.

    My Thinkpad is 6¼ years old and the batteries it shipped with are at 72 and
    75 % of their original capacity. But I didn’t use them *that* much, and always kept them betweet 40 and 80 % charge when I didn’t need them, which
    is probably 98 % of the year.

    1 year is pretty short but possibly he might buy a new battery as
    a test. They generally aren't overly expensive.

    I don’t believe that they went down to 25 % of their original capacity
    within a year. To achieve that, they must have endured unspeakable abuse.

    Note that most batteries these days in anything more complex than a watch have "smart" charge controllers and so upower or similar can read what
    their design watt-hours and current maximum capacity are. Also, often the total charge or discharge rate. That plus a little math should tell you if it's an aging battery or if your machine is simply failing to idle down for some reason.

    LMP

    Larger capacity batteries have multiple banks in them connected in parallel. Some times one of the banks or its controller(?) fails and while the rest continue to work, the loss in capacity is a noticeable step change. I recall suddenly losing ~1/3 of the battery capacity on a laptop just 3 or so happy years into its life. The remaining of the battery capacity continued to degrade slowly and gradually over many years. So notwithstanding the high consumption identified by the OP the software causes of which should be investigated, there could be also a problem with the battery unit itself.

    BTW, short & frequent top ups of lithium-ion batteries is the best approach to their charging, while deep discharge can guarantee a shorter effective life.
