Battery Life, Power Consumption & Portability Index
Battery Life & Power Consumption
The IdeaPad Y510p has the same removable 72Wh battery as the model it replaces, but it has a slightly shorter battery life, coming in at 138 minutes, 20 minutes less than the IdeaPad Y500. The reason for this can be attributed to its CPU and GPU, both of which have marginally higher rated TDPs. This means that power consumption comes in at 31.3W, which is the second highest amongst the notebooks here - only the Alienware has higher power consumption.
Our Portability Index factors in battery life, weight and volume so you can see which notebook is the most worthwhile to carry around. Given the average battery life, slightly high power consumption figures as well as its relative bulk, the IdeaPad Y510p did pretty poorly in our Portability Index, scoring just 0.245. Comparatively, this is significantly lower than notebooks such as the MSI GE40 and Razer Blade, but not actually that far off when compared to 17-inch notebooks such as the MSI GS70 Stealth and Razer Blade Pro. The latter two did better, but only because they were designed to be slim from the get-go and have a thickness of only around 22mm.
