I bought this laptop (link below) and have now had it for almost a week.
How can it be that the battery runs out so quickly? And the remaining time goes down very quickly, with 71% battery it is just over 3 hours, 2 minutes later with 70% it is just under 2 hours
What can be the reason? Do you have to calibrate the battery somehow because the device is new?
I would go to the electronics store (depending on what is with you).
Just have the thing checked.
It can of course also be that you have caught a virus, but it can also be that the thing is made that way.
