Newly replaced battery crashes at ~30%; suspicious battery levels
Hi all,
I have just successfully* replaced my MacBook Pro Mid 2014 battery using the iFixit guide and kit. I am noticing now two main issues, which I assume are interconnected:
- When running on battery, the computer crashes at ~30% and cannot be powered back on until it is plugged in with the AC adaptor.
- The displayed battery levels & charge times on the menu bar are suspicious.
- I have *just* plugged in my device and it is at 28% with an expected charge time of 8:25 until full.
- While infrequent, I have seen the displayed battery level % jump from the 25-30% threshold up to 50-70% for a moment before jumping back down
I suspect (and hope) this is a calibration issue.
Steps I have taken thus far:
- Initial calibration (charge to full +2 hours; drain battery and wait 5 hours; charge up to full)
- Reset SMC
- Reset PRAM
- Checked System Info - Power (see attached screenshot)

Thank you for your help!
Is this a good question?
