Smartphone batteries these days aren’t necessarily getting a lot better compared to back in the day. Sure, we have phones with larger batteries and more efficient chipsets, but ultimately, we’re still getting about a day’s worth of use, maybe a little longer for some devices, but they are nowhere close to the battery life the Nokia 3310 used to give us.
That could change though, because Samsung and IBM have announced a partnership in which both companies are working together to develop new battery tech that could allow our smartphones to run for an entire week on a single charge.
This comes in the form of a new chip architecture that could potentially reduce the amount of energy consumed by as much as 85% called Vertical-Transport Nanosheet Field Effect Transistor (VTFET). As the name suggests, this new design will allow signals to travel across the chip vertically by stacking transistors on top of each other.
As a result, this could allow phones to perform just as well as they do right now, but with massive gains in energy efficiency. Alternatively, this design would also allow phones to improve on its performance by as much as 100% compared to modern FET alternatives.
When exactly we can expect to see this tech used remains to be seen as right now it is still a prototype, but IBM claims that the new design has the potential to scale beyond the nanosheet, which means that turning it from a prototype into a commercially produced solution shouldn’t be too difficult.
