Dell Inspiron 15 7559 4K Laptop Review

I used PCMark 8‘s battery benchmark to give an estimated battery life. This benchmark loops the ‘Home conventional' test until the battery fails, and I kept screen brightness at 50%.

3 hours 18 minutes is a very respectable result, especially for a 4K laptop with the powerful i7-6700HQ under the hood. Under normal circumstances, 6 hours of battery life is essentially guaranteed.
