Is there a way to have a look at the amount of hours my pc was on battery before I plugged it?

Sort of like what you get on iPhones.

"4h 46 minutes since last charge."

When I unplug it at 100% it usually gives me unrealistic numbers like "5h45 before the next charge" but that rarely happens unless the screen remains idle. I don't know if we can monitor battery consumption time better. Any suggestions? Thanks.
