I just did a battery replacement using the iFixit kit and it went smoothly. However, now even after fully draining / charging for 8+ hours it displays around 85% charge. I’ve also done several resets to no avail. My guess is the battery indicator might need calibration but is unable to pick up the new charge. Anyone has any ideas on what might be happening? Thanks!

Defective battery. I assume you mean it will only charge up to 85%?
