    On my old Lenovo Y50, I could use the included Energy Management util to have the laptop stop charging my battery at ~60% in order to keep it from being always fully charged and not heat up.

    I had been having a problem with my G501JW's battery, in that it wasn't working. Computer would just die when you pulled the cord even though though the battery was fully charged and wouldn't start on battery. I re-seated the battery cable and it works on battery now, but it gets very warm when charging, and I've had this laptop less than a month and have 7.8% wear already. I think this is due to Windows always keeping the battery topped off, which is not good for lithium batteries.

    So the question is, does Asus offer a tool like the Lenovo Energy Management utility that allows me to stop the charge before 100%? I rarely ran my Y50 off the charger, but the battery stayed right at 60% the whole time I owned it, and had very little wear (probably like 2-3%) over almost a year.

    Nothing, huh?

    Well, that's excellent. My laptop has run on the battery for a total of maybe 4 hours in the past month I've had it and my battery wear is at 8%.

    It's not uncommon to have a 7-10% battery wear from the factory. That's within margin of acceptable (for them) charge level. Most lithium batteries have smart circuits and they are not always being charged, and running at 80% or 99-100% really doesn't help a whole lot. Batteries will lose 5-7% annually whether they are at 20%, 40%, 60%, 80%, or 100% and never used or occasionally "topped off". All depends on the freshness of the batteries and smart chip, etc, but lithium batteries just lose charge over time, period.

    Also, what are you using to tell you battery wear? I would download and install battery bar (worth the $4 IMHO). It has free limited capability, and free 30 days for the "pro" version to try before you buy. But you will need to do a full discharge and recharge (slowly, not hammering it while gaming on battery or anything) to get an accurate battery wear level. Draining to 3-5% left should recalibrate it to show proper levels. If battery gets really warm while charging though, could be a faulty battery, although some raised temps are normal since it's doing work to charge it.
