Heating and battery life
Gaming laptops in a thin body often suffer from two flaws – overheating and short battery life. What to do if you want high processor performance, but in a thin body, with good battery and at the same time not lose graphics performance when you are at home or at work? A gaming notebook with dedicated graphics card will always be heavier than an ultrabook and will not offer such battery life. On the other hand, ultrabooks lack CPU performance. The Legion Y740S resolves this dilemma.
Heating and battery life
Maximum CPU temperatures are relatively high with a maximum of 101 degrees. Again, however, this is the maximum value, which is usually the result of a rapid increase in performance and then falls slightly. We will look at a more detailed analysis when comparing the modes and extended Blender tests. The absence of eGPU could mean more stable CPU performance.
Battery life is very good, over 5 hours, which is unusual for gaming laptops. The Y740S has the advantage of the absence of a dGPU and, for example, G-Sync, which often significantly reduce endurance. Nevertheless, this is a very good result, considering that we have a 45 W processor and a 15″ screen, but the result is not far from 13–14″ ultrabooks.
