install new battery from ifixit, but battery only last for 2.5 hour
Purchased a battery from fixit to replace the OEM battery in MacBook Air 2015. After installation, and calibration, the battery only last for 2.5 to 3 hours before completely drained. I calibrated the battery as stated on the website multiple time and it does not seem to help the issue.
Should I be getting longer battery life than that? I remember the OEM battery last couple 6 to 8 hours for normal use
I use Coconut Battery to look at the battery. It looks like the battery was made almost 2 years ago, and it is only charging to 92.5% of the designed capacity.
Any suggestions will be helpful.
Is this a good question?
