Wikipedia: Smartphones is the encyclopedia's main reference entry for the pocket computer most of the planet now carries. It opens where the technology did, with the IBM Simon in 1994, then moves through the Nokia Communicator line and BlackBerry before reaching the 2007 iPhone launch and the spread of Android that followed. Anyone trying to trace how a phone turned into a general-purpose computer can read the whole arc in one place, with dates and device names laid out in order instead of scattered across marketing pages.
Breaking down smartphone hardware components
What gives the entry its weight is how far it goes past that history. The section on internals reads like a teardown written out in prose. It explains why mobile CPU architectures are tuned for low-power operation, walks through display families from LCD to OLED to e-paper, and lists the sensor set most handsets ship with: accelerometer, barometer, gyroscope, magnetometer. Storage gets the same treatment, covering eMMC, UFS flash and microSD, alongside notes on lithium-ion and lithium-polymer battery chemistry, optical image stabilization in camera modules, and the casing materials makers choose between, from polycarbonate to aluminum to glass. A reader who wants to understand a spec sheet can decode most of it after a pass through this page.
Comparing Android and iOS market share
The software half is just as thorough. Wikipedia: Smartphones gives the operating-system split as Android at 85.9 percent of the global market against iOS at 14.1 percent for the first quarter of 2018, then explains how apps reach devices through manufacturer-hosted stores such as the Apple App Store and Google Play. It folds in the role of HTML5 and web apps as an alternative distribution route as well. That mix of figures and mechanism is the sort of thing a buyer's guide skips and a reference work is supposed to nail.
Tracking global shipment data
Market data runs through the article as a steady backbone. The numbers are specific: more than a billion smartphones sold every year since 2014, 1.54 billion units shipped in 2019, and 75.05 percent of the world's population using one by 2020, with a note on Samsung's lead in manufacturing volume. Wikipedia: Smartphones also tracks what these devices swallowed on the way up, replacing PDAs, portable media players, dedicated cameras, GPS units and handheld game consoles. Reading those convergence notes together makes it obvious why a single product category got so large so fast.
One structural strength is the way the page hands off. Wikipedia: Smartphones distributes detail across sub-articles on smartphone generations, individual operating-system histories and specific hardware topics instead of cramming everything into one screen. The main entry stays readable while the deeper rabbit holes sit one click away, which is the right balance for a subject this sprawling. A business directory might list smartphones as a product category and move on; this page explains the whole field from the silicon up.
Documenting health and safety risks
The article is not a cheerleader for the technology, and that is to its credit. A substantial block deals with the downsides. It documents distracted-driving risk, the sleep disruption tied to blue light, and the pedestrian-safety problem that picked up the "smombie" nickname for people walking head-down into traffic. These are not throwaway lines but cited passages that sit on equal footing with the hardware coverage.
It also looks further up the supply chain than consumer writing usually bothers to. Wikipedia: Smartphones raises the manufacturing concerns around cobalt and lithium mining, including child labor, which connects the glossy finished product to the conditions under which its raw materials are pulled out of the ground. A person who only knows phones as shiny objects in a store will find that section uncomfortable in a useful way.
The tone across all of this stays even. Praise for camera stabilization and the public-health caveats live in the same document without one drowning out the other, which is harder to pull off than it sounds and is exactly what a general reader should want from a survey of the topic.
Verifying claims through citations
Two things shape how trustworthy the page feels. The first is sourcing: claims carry inline citations and the article closes with a full reference list, so a skeptical reader can chase any statistic back to where it came from instead of taking it on faith. The second is the open model behind it. Wikipedia: Smartphones is free to read and open to editing under Wikipedia's licensing, which means errors get caught and the figures get refreshed as the market moves, though it also means a given number reflects whenever its source was published. Treating the percentages as snapshots from their cited years rather than live readings is the sensible way to use them.
For depth on a single subject, Wikipedia: Smartphones covers more ground than almost any single source a casual searcher would otherwise land on. The history is dated and ordered, the hardware is explained at component level, the software and market figures are precise, and the harms are documented with the same weight as the hardware coverage. The curious reader, the student writing about mobile technology and the shopper trying to make sense of a spec sheet each get something useful here, because the article lets each of them stop at the level of detail they need and follow a link when they want more.
The reach of the article is wide enough that it functions as a map of the whole field. Where a product page sells one device, Wikipedia: Smartphones explains the category that device belongs to, from the silicon up through the operating system and out to the social effects. It names the milestone devices, gives the shipment counts, and lays out the convergence story without asking the reader to already know the jargon.
If there is a limit, it is the one built into any reference snapshot: the market-share and shipment figures are anchored to the years their sources cover, so the 2018 operating-system split and the 2019 shipment total describe those moments rather than the present. The structure handles that gracefully, since the dated statistics sit beside durable explanations of how the hardware and software work, and those mechanics do not expire the way a quarterly number does. The conceptual scaffolding holds up regardless of when the page is read.
