I’ve just spent the afternoon with Nvidia at Computex 2026, where the company went into more detail about its freshly announced RTX Spark chip, and the upcoming laptops that will be powered by it. One of the most pressing questions I had — as did many of our readers — is what kind of battery life we can expect with an RTX Spark laptop.
I put this question to an Nvidia executive, who said that while they can’t provide firm numbers just yet (we’ll have to wait until closer to the Fall launch of the first wave of RTX Spark laptops), we should “expect all-day battery life” when using these laptops for regular workloads.
Unplugged power
While this answer is a bit vague, it’s good to know that we can expect laptops that you can work on for over an entire work (or school) day without needing to plug them in.
Battery life (and lack of) is one of the biggest pain points for Windows 11 laptops, especially compared to the best Chromebooks and MacBooks. And while the situation has improved — mainly thanks to more efficient chips from Intel and Qualcomm — battery life improvements are always welcome. That’s especially true if Nvidia wants to deliver on its promise to reimagine the PC with RTX Spark.
According to the Nvidia employee I spoke to, the longer battery life is thanks to the fact that the RTX Spark chip combines both CPU and GPU, which is far more efficient than having separate chips for those components.
Later on, another Nvidia employee told me that RTX Spark laptops will maintain their performance when running on battery life, so users shouldn’t see a dip when they unplug their device.
Again, this has mainly been a concern with Windows 11 laptops. In the past, laptop performance has been throttled to prevent the batteries from draining too fast (less power used by the components means less battery life used), so this is great to hear, especially as Nvidia is pitching the initial wave of RTX Spark laptops as mobile productivity machines.
Nvidia also confirmed to me that we should expect a similar level of performance as the laptop version of the RTX 5070 graphics card. Hopefully as the launch of RTX Spark laptops approaches, we’ll get more in-depth details about what to expect from this new breed of PC.
