Despite facing a range of geopolitical and market challenges, Apple's iconic iPhone remains one of the most popular pieces of technology in the digital age.
Last year saw Chinese iPhone shipments decline by 2.5 million units, against the backdrop of an economic slowdown and burgeoning trade war between China and the U.S.. At the same time, the tech giant also lost 18% of its share value during the final quarter of 2018, amid growing concerns of market saturation.
However, the iPhone remains an incredibly advanced smartphone that boasts exceptional performance and longevity. In this post, we'll look at the components that underpin the product and ask what's inside your iPhone?
1. Non-volatile Memory
Unlike some smartphones, iPhones are unique in that they feature non-volatile memory (NVM). This is a type of computer memory that has the capacity to hold saved data even if a device has been switched off, while it's commonly used for secondary or long-term storage.
Most iPhones feature what's referred to as a NAND chip, which is so called due to its use of NOT and NAND gates. This is an advanced iteration of a non-volatile memory chip, and one that adds tremendous functionally to Apple products and flexibility to users.
There's a wide range of similar, non-volatile memory chips available online, through retailers like RS Components. Interestingly, they can also be used in other technological devices including digital cameras and desktop computers.
2. LCD or LED Displays
It's interesting to think of iPhones (or indeed any smartphones) as being modular, particularly when you consider how they're designed, packaged and sold to the public.
The iPhone display is actually an internal component, for example, which will typically be underpinned by either LED or LCD technology.
There are some subtle differences between these two screen types, with LCD displays boasting a backlight which illuminates everything that you see on the phone's interface.
In contrast, LED screens feature light emitting diodes that illuminate the display, creating a more efficient source of energy and a superior colour contrast.
3. Non-Removeable Lithium-ion Batteries
Battery technology has evolved considerably over the course of the last few years, and this has had a positive impact on smartphone design and performance.
In the case of iPhones, these devices now tend to feature non-removeable lithium-ion batteries, which provide a more sustainable source of power and negate the risk of calibration or testing issues.
These issues plagued the previous generation of nickel-based battery phones, while making handheld Apple devices far safer to use and longer-lasting.
