Hi all,
after updating to Big Sour (11.2.2) my battery doesn't work well: system says "Service reccomended" and indicate 7h for a full charge starting from 82%.
Battery cycle count is 85. Anyone has same problem? Is possible to resolve?
Thank you
MacBook Pro 13″, macOS 11.2
Since the SMC Reset did not produce a positive effect and still getting Service Battery - make a Time Machine Backu asap and have Apple Authorized Repair Dealer or Apple Store evaluate the battery
Start by resetting the SMC. That should be enough to fix things.
Hi, thank you for your reply. I tried to resetting SMC but nothing happen, system still reccomended service... these are battery info taken from system information, if they can be useful.
