My battery life

I’ve had niimo, my laptop, for less than a year now; I got him on the 27th of June-ish. And in less than a year my battery life has dropped from two and a half hours to forty-five minutes.

Battery ish dead

When I got the laptop I was told to only have it connected to the power when it needed to be charged; so I’ve religiously unplugged it when it gets to 100% and plugged it back in when I only have 2 or 3 minutes left. I dunno what’s happened…
