Of the two, Android has been the best-selling system worldwide on smartphones since 2011, and as of March 2025, Android had 71.9% of the overall market share, while iOS had 27.7%. Feature phones have basic software platforms whilst smartphones have a fully-featured operating system (commonly abbreviated to an OS), with the two most-used platforms being Android and iOS. The SIM card is approximately the size of a small postage stamp and is usually placed underneath the battery in the rear of the unit. Most modern mobile phones use lithium-ion (Li-ion) batteries, which are designed to endure between 500 and 2,500 charge cycles. Some audio-quality enhancing features, such as Voice over LTE and HD Voice, have appeared and are often available on newer smartphones. Because of these problems, the performance of mobile phone CPUs is often more appropriately given by scores derived from various standardized tests to measure the real effective performance in commonly used applications. Mobile CPU performance depends not only on the clock rate (generally given in multiples of hertz) but also the memory hierarchy also greatly affects overall performance. Mobile processors commonly use heterogeneous multicore architectures, combining cores with different performance and power characteristics so that computational workloads can be distributed according to their processing requirements and energy constraints.

The typical lifespan of a mobile phone battery is approximately two to three years, although this varies based on usage patterns, environmental conditions, and overall care. In many countries, mobile phones are used to provide mobile banking services, which may include the ability to transfer cash payments by secure SMS text message. In developed countries, smartphones have largely replaced earlier mobile technologies, while in developing regions, they account for around 50% of all mobile phone usage. Furthermore, mobile phones offer satellite-based services, such as navigation and messaging, as well as business applications and payment solutions (via scanning QR codes or near-field communication (NFC)). Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. A study by the London School of Economics found that banning mobile phones in schools could increase pupils' academic performance, providing benefits equal to one extra week of schooling per year.
