Is a perennial demand in offices, pubs, stores and on the internet every year in the pre-launch of a new iPhone period: Apple slows down previous iPhones to buy new.
At first glance, the question seems totally absurd: say it was discovered that Apple really hurts older iPhones, the VW diesel gate would be for your smartphone or just a summary of the feeling that something changes is on the old phone. He has in his pocket that he feels really slower.
The truth, at least according to the company’s benchmarking data Futuremark is that contrary to what you would feel in the day, the processor and graphics chip iPhone are as fast as the day who bought it.
Futuremark collected more than 100,000 benchmarking tests from the iPhone 5S to the iPhone 7 and the average processor performance (CPU) and graphics chip (GPU) once a month between April 2016 and September 2017 with different versions of Apple software. from iOS 9 to iOS 11.
According to Futuremark: “The performance of the GPU for iPhone 5S has remained constant from iOS 9 to iOS 11, with only minor variations falling within normal levels.”
The performance of the processor was comparable constantly, which made Futuremark conclude that “it is clear that iOS updates have not had a significant effect on performance.”
The graphics performance for the iPhone 6, 6S and 7 was also constant, while the processor performance decreased slightly with the successive iOS updates.
“The CPU performance graphs show a very slight decrease in performance over time, possibly due to small iOS updates or other factors, but it is unlikely that the user will notice this slight difference in daily use,” Futuremark said.
Although benchmarks show that processor performance and graphics performance are not deliberately hampered by successive iOS updates, people may feel that their smartphones will slow down over time.
This is because as smartphones are more powerful and better capable of updating any new version, applications and services. In addition, they are often more complex as new features and technologies are added, which can lead to the application worse in time, as the smartphone needs more when the application launches and performs during the operation overall.
A good example of the complexity of this application is the Facebook application, which has added more and more features over the years, which grows in size and intensifies the use of the processor in the process. This resulted in several episodes of battery loss, but also delayed the performance of the application.
At the same time, the battery life decreases as a smartphone grows older.
The maximum capacity of a cell decreases after repeated cycles of charge and discharge as a fundamental feature of internal chemistry, which then generates electricity.
While new batteries last longer, due to new electrodes, electrolytes and controller technology, your iPhone 5S battery is almost worse for four years than when it was new. Combined with more bloated applications, it certainly gives the feeling of slowing down and getting worse, even if Apple does not deliberately lower performance.
