Hertz, inches, watts: how has the smartphone for 10 years?



This year marks exactly 10 years to the smartphone, which we used to see him. From 2007 water has flowed much of the technology has gone far ahead and sometimes changed beyond recognition. You can say the flagships of the time — calculators compared to top-end devices of today. But there is at least one important parameter, which miraculously hasn’t changed at all. Understand how the characteristics of your smartphone.

CPU: 50-fold increase in performance

Processors, designed according to the standards of the ARM architecture, was created as if specially for mobile devices, but the roots of this technology goes deep into the 1980s, years when modern smartphone seemed to pseudo-scientific fiction. By the time of the advent of smartphones in 2007, the technology has been well developed, which contributed a lot to the PDA market. The first smartphone iPhone 2G, installed the Samsung processor S3C6400 ARM11, To reduce energy consumption, he worked on the low frequency 412 is 620 MHz.

The ARM processor 11 generation showed a performance of less than one DMIPS for each MHz. The Cortex-A72 grant about 6.35 mm DMIPS/MHz. Rough rounding, modern OCTA-core processor has a capacity of 50-60 times higher than its ancestor of a decade ago. It is clear that synthetic test does not reveal all the nuances, but to estimate the scale of progress it allows.

RAM: up to 8 times faster, three times more economical

Specifically for mobile devices was developed by standard Low Power DDR (LPDDR), which is primarily distinguished by lower power consumption compared to desktop RAM modules. The main directions of development — the growth of communication speed and reducing energy consumption. In 2007, the first generation of LPDDR provided 400 MT/s (million transactions per second). Today LPDDR4 generates 3200 MT/s — eight times more. As decreased power consumption of mobile “RAM”, shows the picture below.

The increase in the number of memory — a direct requirement of most of the users, especially for devices without a microSD slot. Today’s top devices have up to 256 GB of memory. It all started with 4 gigabytes — a growth of 64 times.

 

Mobile Internet: from 384 Kbps to 100 Mbps

Oddly enough, the development of technologies of data transmission through the air tied on the same characteristics: they should provide the fastest data transfer speed at minimum cost of energy. Relevant today (and the next few years before the introduction of 5G) cellular technology was mastered by the manufacturers of smartphones until 2012: that’s when all the major manufacturers predlozili support for LTE, which today provides streaming videos (average 10 Mbps peak to 100 Mbps from LTE-A). It’s hard to believe that the first of the smartphones (and the iPhone too) to connect to the Internet at EDGE speeds of up to 384 Kbps (48 kbps), 3G support (up to 2 Mbps) was considered a breakthrough.

“Starter” Wi-Fi standard in smartphonetoday — IEEE 802.11 g: he supports a signal frequency of 2.4 GHz and provides a channel to 54 Mbit/s In 2009 was certified by a standard n: channel up to 600 Mbps and supporting a second frequency of 5 GHz, and in January 2014 approved a new standard 802.11 AC, which is now supported by the flagships of leading manufacturers. Its theoretical limit is the “space” of 6.77 GB/s.

Display: more and brighter

The standard screens have a resolution of WHD+, that is 2960×1440 points that give under 600 ppi. (3840×2160 resolution and ppi 804 Sony ZX Premium while, for clarity, we deem the experiment). Remember that the displays of the first smartphones does not even reach 200 ppi, having a diagonal, almost half. However, the race for screen size and pixel density is just one side of the coin.

Another involves hunting for conserve precious energy for realism and color accuracy, including angles. These parameters determine the development of various technologies of displays, the most popular of which today are IPS and AMOLED in various versions. Year by year, technologies are evolving, and to distinguish the picture in different matrices, the average user is becoming increasingly difficult.

Battery: 10 years as one day

In each of these regions certainly present a very important parameter: the power that producers from year to year reduce. The nominal battery capacity of Android-based smartphones have increased on average by half. For example, the popular HTC Hero was equipped with a 1340 mAh battery. Today “normal” battery capacity can be considered to be 3000 mAh. Interestingly, in the Apple world, the situation is markedly different: AKB iPhone 7 only 560 mAh “roomier” in the first line device: 1960 instead of 1400 mAh. Charging the battery was quick and, optionally, the wireless.

The only thing that has changed over the years — real-time battery life. The “average” smart phone 10 years ago, and today can withstand without recharging the day.

It is clear that the main consumers of energy — the screens are bigger. It is clear that “heavier” is mobile content: video, games, pictures. But this years accuracy unintentionally encourages within the scope of the conspiracy. What if the manufacturers deliberately keeping us at the level of a necessary minimum: the battery should be enough until the evening, when we still go back to the bed, near which there is a power outlet. Non-removable battery that has lost a large amount of capacity for a year or two of use — all the more reason to think about replacing the smartphone. How not to recall here about a conspiracy of manufacturers of light bulbs?
