My question is as above. How many hours are in a normal range and how many hours should it last at least?
Mine lasts 5 hours.
Very different. Depending on performance and battery capacity. I expect 8 hours from my Mac, but I'm nowhere near it.
Depending on the age of the battery, 5 hours is an excellent average.
5 hours is already a good one, because when professional laptop users use the mobile, they are never in the company for a whole working day, and when there's a power socket nearby. Battery operation is always only for the short term, and of course that also depends on the required load, so you can maybe have 6 hours with mostly empty space with a little Internet, if it has to work properly, the battery is empty in half the time
That depends on how much the laptop is used in battery mode and how old the battery is.
5 hours are not bad and are well in the midfield.
I would say 5 hours is okay, of course it also depends on how much power your laptop draws, if you make the screen a little darker, your battery might keep a little longer, another tip don't leave the battery uncharged for a long time 70-80% is good.
