Chosen Solution
I bought a new battery from ifixit less than 11 months ago for a 2015 Macbook Air. The battery worked great until early this month when it would suddenly drop from ~40% to ~7%. Then it showed that the battery needed servicing. I downloaded CoconutBattery and it says the battery is at 23.9% design capacity. I’m assuming I need to replace the battery yet again. Is it normal for the battery to die so quickly?
You have a years warranty on the battery I would strongly recommend you contact the iFixit Store for an exchange battery Contact iFixit Customer Support
