On my Windows laptop, I usually set my battery to be more efficient. But when the battery is running low, I switch to power saving mode. However, there are fewer minutes left after you activate the saving function. Example: If the battery is more efficient, I have 1 hour 30. In energy-saving mode, then only one hour. Can anyone explain to me?
It's a question of which app stopped that.
The Windows own app or that of the manufacturer or a mix of both.
Then you have to adjust the power plan yourself.
That's just a thesis. Battery efficiency and energy saving are opposing properties. Battery efficiency can mean that the battery is not discharged as deeply.
