I am getting about 3hrs of battery life with just the activity monitor and with the screen on (66% of brightness)
I did have a similar problem two years ago with another ifixit battery I bought for a MBP 2011 13”, I sent it back and bought a Newer Tech battery that also reports an inaccurate percentage. I am really frustrated with this after spending 80€ on a battery that is supposed to be of high quality.
