Mobile phones are rapidly becoming touchscreens and touchscreen phones are increasingly all-touch, with the largest possible display area and fewer and fewer hardware buttons. The hardware matters, but the underlying OS is the same , and pretty much all apps will run on any device of the same age. This is not true. Personal Computer.

Google's Search App and Facebook's various apps for Android undermine these choices in slightly different ways. [3] Developers also suffer higher costs and reduced opportunities to escape Google, Facebook, and Apple's walled gardens. iOS gained browser support in late 2020 (a dozen years late) via an Entitlement.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Meanwhile, budget segment devices have finally started to see improvement ( as this series predicted ), thanks to hand-me-down architecture and process node improvements.

Each smartphone comes with various screen sizes and resolutions, operates on different network speeds, and has different hardware capabilities. The graph below shows the result of a survey performed by Statistica in 2020 on the increase of usage of mobile data across years. Google ranks applications based on how user friendly it is.

Micro-optimizations are great for keeping performance on track, but it’s critical to have clearly defined targets in mind — measurable goals that would influence any decisions made throughout the process.

is an open collaboration between Google, Microsoft , Intel , Samsung , and others to safely bring capabilities to the web which native developers have come to expect. After all, those are properties that browsers compete on, benefiting users in the process. In each quantum of time, hardware and OS vendors press ahead, adding features.

So by late 2020, things got a bit out of control, with yellowish-red Lighthouse scores slowly showing up across the board. In early 2020, we’ve started with the big refactoring of the CSS layout components. The performance distribution for Largest Contentful Paint in 2020. We had to fix that. That’s Where We Were.

When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware. I believe this range of mobile hardware will be illustrative of performance across a broad spectrum of device capabilities, even if it’s slightly heavy on the Apple side.
