My Macbook battery drains to 83% overnight??
I have been using this Mac for two years straight; in those two years, I used this mac all the time and did mostly CPU-heavy tasks. My battery charge cycle as of this moment is 1247 cycles. And after 12 hours overnight under sleep mode, the battery drained to about 80%
Is it recommended I replace the battery now? or can I just use this Mac while plugged in to save battery life?
MacBook Air 13″, macOS 10.13
