If you know anything about lithium ion batteries, you know they don't react well to sitting at full/near full charge for periods of time. My GL702 sits on my desk plugged in all day, which causes the battery to stay at 96% perpetually... not good long term if you want the battery to last. Turns out ASUS built a program to remedy this problem, but seems to only include it on the Zenbook lineup. You can download it below though, and it works perfectly on my GL702.
You get the option of a full charge, no greater than 80% charge, and no greater than 60% charge. The 60% setting is the best for longevity - use this if you always leave your laptop plugged in. If you occasionally unplug and go somewhere to use your laptop, it'd be best to sit at 80% and then charge to 100% right before you need to use it.
I've had some issues because of this myself. Thanks for the link. Seems to be working on my GL702VMK. I am guessing that even the 80% mode would be better for your battery than the usual 96-100% all the time.
