A failing battery?
So I’ve been noticing that along with the previously mentioned problem of GNOME not knowing when my AC power is plugged in or not, my battery’s life seems to have been cut in almost a third. I used to get approximately 3 hours of runtime on battery, but lately I have been getting just about 1 hour. The time to charge the battery to full has also increased by a pretty significant amount of time than I remember.
GNOME’s battery applet and acpi -V show the battery doing fine up till about 65% charge and then it just plummets to 5% battery and low battery warnings appear. That’s quite a drastic drop.
For instance, here’s some of the graphs from GNOME today of my battery:
5 minutes later:
Looking at those graphs makes me believe that my battery may be standing on its last leg, but I’m not really that knowledgeable about laptop batteries.
Is it time for me to start looking for a replacement battery at this point? Or is there possibly some way to salvage this battery. It’s not really that old, about a year old if I remember correctly. Is it worth trying to recalibrate the battery or is it just shot? Any help is appreciated.
