My Mac book pro 2017 didn't display the warning notification for low battery. I didn't see the function for that in system preference. Can someone help me with this, please? Since it automatically shut down always without warning at 20% battery
MacBook Pro 13″, macOS 11.5
Hi Sharhari,
Thanks for your help, but there is no setting for low battery warning notification? We can set a notification when battery power is in the range of low capacity remaining, I think I set 20% before. I was always using my device when charging so I just noticed this recently. The battery health is in normal condition too.
When using the charger and start the system again, the battery at that time is always around 20-30%, which means it was around that range when it suddenly down.
This is the command in terminal
pmset -g batt
Note: If your system suddenly sleeps on battery power with 20-50% of capacity remaining, leave this command running in a Terminal window. When you see the problem and later power and wake the computer, you'll be able to detect sudden discontinuities (like a jump from 30% to 0%) indicative of an aging battery.
Hope it helps.
You may need to contact Apple support for further help.
