Battery life is often the decisive factor for many of us when we go out to buy a laptop. But, power efficiency of laptops hasn’t increased that much, compared to the advancement in processor speeds. And, the struggle for a long-lasting battery that can power up devices for days without recharging continues. PC-maker Lenovo has released a new infographic which predicts when this struggle may end. The infographic even predicts the emergence of batteries that will last for a week.

That may sound a little outlandish at this moment, but that is quite possible. The hardware, including the processors and other accessories, is becoming more efficient, compact and less energy-consuming with time. Every few months, a chip-maker dishes out a new processor which is more efficient as well as power-saving.

This is further bolstered by the fact that the technology that goes into constructing batteries for the laptops has also advanced significantly over time. A number of new methods to provide battery-life to electronics are being explored.

These two factors may eventually make it possible for laptops to last for an entire 40-hour work week. After all, we started off with a battery life of 25 minutes for laptops back in 1991, and over time we have come to a place where laptops can now work for up to 9 hours on a single recharge.

According to Lenovo, at this pace, we can expect the battery life to reach up to 24 hours in 2018 and finally, 40 hours in 2023. You can read the infographic below.
