Chosen Solution
I recently installed a new battery (from iFixit) in my early 2011 MacBook Pro. 3 to 4 years ago I installed another iFixit battery in this computer with no issues. This around, my computer does not seem to be able to calibrate with the new battery. I’ve followed the calibration instructions from iFixit, and tried a few initial troubleshooting procedures, but with no luck.When my computer is not plugged into a power source, my battery icon shows 100% for a short while before continuing to show 100%, but turning red and indicating that I am low on battery. The battery percentage will rapidly drop from 100% to 5-7% and shut down shortly after that. Please let me know if there are any other calibration or troubleshooting techniques that I should try in order to get my computer to allow the battery to truly receive a full charge.
OK, it does look like you’ve done at least one cycle calibration already. So maybe we need to not be so focused on that and look at what you are encountering. At present your battery is fully charged so if you where to unplug it how long would it take for the system to shut down (not sleep) Lets use a web site which doesn’t have any gif’s or video elements iFixit’s home page will do.
