Battery Issue
I have an issue with my Macbook pro 13" 2019. The battery won't last long, it drain so fast. I can use about only 3 hours for Microsoft Office software.
Do anyone have the same issue or not?
MacBook Pro 13”, macOS 10.14

Depending on the settings, and the total of everything that may
be running in background, the battery life can significantly vary.

The above is good source of linked information to read & understand.
You can limit the battery charge-discharge cycle (count) by careful use
and choosing to not run battery near depletion; let it charge when AC
power is available, and use adapter when you can.

This is fairly concise bit of additional information not necessarily cover-
ed in earlier linked pages, and offers perspectives in troubleshooting.
