That old phone sitting in your drawer may have more life left in it than you think.You may look at it and see a dead battery, an outdated camera or a screen that no longer feels worth using.
Google and researchers at the University of California San Diego see something else: a tiny computer that may still have useful processing power.Their idea is called phone cluster computing.Instead of treating retired smartphones as electronic waste, researchers remove the motherboard and redeploy it as part of a low-carbon computing system.Google says UC San Diego plans to launch a data center built from 2,000 Pixel smartphones in fall 2026.
The goal is to provide low-cost cloud computing for students and researchers while reducing the need for newly manufactured server hardware.That means the next chapter for an old phone may not be a junk drawer.It may be a server rack.YOU COULD GET PAID FROM GOOGLE’S ANDROID DATA LAWSUITResearchers plan to launch a 2,000-phone data center at UC San Diego in fall 2026 to support students and research workloads.
(Kurt "CyberGuy" Knutsson)Sign up for my FREE CyberGuy ReportPhone cluster computing takes retired smartphones and turns their core hardware into a computing platform.The process starts by stripping each phone down to the motherboard.
That board holds the processor, memory and storage.The display, battery, cameras, chassis and other phone-specific parts are removed.That step is important because a full phone does not belong in a data center.
Batteries can create safety issues.Screens and cameras waste space.
The motherboard is the part that still offers computing value.Once the board is removed, researchers load a general-purpose Linux system onto it.Android already runs on Linux at its core, but Android is built for mobile apps and personal devices.
A data center needs something more flexible for cloud workloads.After that, the phone boards can be grouped into clusters.
Many small boards then work together like a collection ...
