Question

Laptop battery problem...What's the issue?

Jul 27, 2017 5:42AM PDT

I recently purchased a ASUS R558UQ from it's exclusive store. After around 1 month of usage, yesterday I noticed that the charge percentage of my laptop didn't seem to increase. I kept it on charge at 80% while watching a movie. When checked after 30 minutes the charge percent remained the same. Sometimes it charges till 90% and it gets stuck there. Notification still showing plugged in and charging
Following a battery calibration process the issue still stands adding sudden hibernation while using. Can someone please tell me what's wrong? Thank you.

80% sounds right for

For example the battery life extender setting would limit the charge to 80 or so percent to maximize the life span of the battery. This however can confuse owners that want a 100% charge.

As to the sudden hibernation that's anyone's guess but I'd ask the maker for support on that.

Again, it sounds like the battery life extender setting is on, not a calibration issue.

The 80% is on purpose

Looks like R. Proffitt was in a hurry, or typing on a phone. He didn't flesh out his answer.

It's a trade-off between having more battery power in this particular unplugged session vs the overall life of the battery. The 80% is showing you that there is, actually, some more room for charge into the battery. But, if the laptop does charge the battery to 100% every chance it gets then your battery life may begin to drop off dramatically in two years instead of five. (I'm making those numbers up, but you get the idea.)

There is probably an option you can set to turn off the battery life optimization. Search for your laptop model.

It would be the thing you want to turn off for a special event, where you need every minute of battery. But, you would want to turn it back on if your laptop spends most of its time sitting on a desk attached to the wall.

OTOH, if you routinely need to use your laptop on battery, and can't plan ahead on when that will be, then you'll have to realize that your battery will need to be replaced sooner.
