I'll usually hold onto my laptop for 4-5 years and smartphone every 3 years. I tend to buy top-of-the-line with decent price-to-performance ratio electronics so it takes a long time for them to feel cost-effective to update. And as time's gone on, the jumps in performance don't feel like they mean as much to me compared to say battery life (which is an easy repair to get a new one) so like every one else, I'll probably start holding off upgrades longer. A lot of times as new features are added out there and others are dropped. For instance, my wiped 2016 Razer Blade running Linux has no-longer-upgradable BIOS because of Razer's demand of Windows 10 to launch a GUI just to upgrade them. I'd like to migrate to another brand for the Spectre and Meltdown vulnerabilities alone, but the Nvidia 1060 is still good for most uses and it's hard to find a worthy replacement laptop with a hi-res screen supporting 100% AdobeRGB or DCI-P3 for photo work. Phones are hard to upgrade because now everyone wants to drop the 1/8-inch headphone jack I rely on.
