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.

Make sure you don’t have something running hard or wild, open Activity Monitor app to see if something is chewing your power

If you don’t see anything, I would contact iFixit to get a replacement, clearly 2.5/3.0 hours is not normal.

Get it replaced, sounds like you got old stock. This is why I don’t buy parts from ifixit, only tools.

Where would you recommend getting parts from?

@strongbow - I’ve used their batteries for quite a few years and many others have as well. COVID has messed up a lot of supply chains, iFixit has of late been bit a few times, in any case they have always stood by their warranty.

@mic85 - Did you contact iFixit? I’m sure they will take care of you as long as it’s under a year (even being over a few weeks I’ve seen them take care of their customers)

In any case make sure you get a good warranty and from an outfit that’s been around at least a good five years.
