I’m currently experiencing a concerning battery issue on my MacBook Pro and wanted to share it here in case others are facing something similar or if it’s possibly tied to a software-level behavior.
Device & Software Info:
• MacBook Pro 14” (2023)
• macOS 26.0(25A5316i) • Battery Cycle Count: 307
• Battery Health: 91% (as of today)
• Condition: Normal
Issue:
• Battery health has dropped from 96% to 91% in less than a week.
• For the last week each day, the maximum capacity seems to decline by 1%, even when usage is light and the Mac is plugged in most of the time with Battery Health Management enabled.
• When the battery drops below 10%, it drains extremely fast — the percentage decreases nearly second by second, which doesn’t feel normal.
