Sony is preparing a 40% more powerful battery for its upcoming smartphones

Sony's high-end are deemed to offer excellent battery life of about 48 hours. But the Japanese automaker is determined to go further and prepare a 40% more powerful battery for its upcoming smartphones.

Both increasingly powerful and increasingly thinner every year, our smartphones are constantly evolving in all respects except one: the battery. Consumers are disappointed, manufacturers try to compensate with other technologies such as fast charging are but few smartphones can boast of offering more than one day of autonomy, and again.
That said, if there is one that stands out, it's Sony. And although the Xperia Z5 we tested at its output sometimes struggles to achieve 48 hours of autonomy promised by the manufacturer, it remains above the rest. Still, Sony seeks to go further and according to a new report from the Nikkei site, the Japanese manufacturer would work on a new battery based on lithium sulfide instead.
More efficient, it would offer a range 40% greater than that of lithium batteries batteries on a single charge. In fact, it would just be able to store 40% more energy. In addition, capacitance also, it is 30% thinner than the current batteries.
Of course we want to believe. Sony remains one of the largest battery manufacturers in the world. Moreover, it is to him we owe the first Li-ion battery commercially viable, launched in 1991. Hopefully, still it will not push manufacturers to offer more smartphones purposes but the same size devices that today offering greater autonomy.
Note that the first calculations have demonstrated that if the iPhone 6S was equipped with future battery Sony sulphide, it would offer 14 hours web browsing against 10 to 11 hours currently. Only small problem but size, the new battery should not land on the market before 2020.
