The performance of the Inspiron 15 7577 is comparatively good. We’ve put the notebook through a series of tests that provide more insight into the actual performance of the processor and graphics card. Current game titles can easily be played on high details, but you should also pay attention to the volume of the fans, which should not be underestimated. During normal operation, however, the fans are all the quieter and even under load they come off better than competing products.
As far as the battery is concerned, a glance at the technical data reveals that it is less powerful than the one used in its predecessor. The number of cells was reduced from six to four, which, as expected, also leads to a reduction in battery life. With a capacity of 56 Wh, it is now an average of seven hours – in the predecessor model, however, the battery lasted an average of ten hours.
The reduction of the battery size seems appropriate in view of the also quite small batteries of the competition, but will certainly be annoying for some users. It takes about two hours to fully charge the built-in battery.
At this point you can find the first clear point of criticism of the device. Although the reduction of the battery size is understandable for economic reasons, Dell will annoy customers who own the predecessor model. New customers, on the other hand, shouldn’t notice the reduction in size, as the previously oversized battery is now on a par with competing products.
