Consumer group Which? carried out a series of benchmarking tests on the seven most popular smartphones on the market, and found that the iOS handset lagged behind the rest.
The phones were put through a series of benchmark tests by Which? to measure processor and memory performance, which show how quickly the phone will allow photo editing, running graphic-intensive games, and using several apps at once.
It is slower than both the main Samsung models as well as rivals from Google, Sony, HTC and Blackberry for popular tasks such as playing games, editing pictures or using apps.
“We put all the handsets through the same tests. Undoubtedly, Apple will upgrade its next iPhone when it launches this autumn,” said Which? in a statement. “For the moment, Samsung’s Galaxy S4 is the phone to beat when it comes to speed.”
Samsung’s 1.9GHz quad-core chip-packing Galaxy S4 came out on top with a score of 3188, with the iPhone 5 chalking up 1664 by comparison and only a 1.2GHz dual-core chip.
“Despite being crowned the world’s best-selling smartphone in February, Apple’s iPhone 5 has aged badly since its launch last year. We measured it against the latest handsets on the market and it finished in last place, with the Samsung Galaxy S4 proving almost twice as fast,” informed the consumer watchdog.
However Which? also said: “Bigger processors do not always mean better speeds – that’s why we put all the handsets through the same test.
“This measures processor and memory performances across smartphone platforms to provide a standard speed rating.”
It added: “If a phone has a high Geekbench score it will perform well when photo-editing, running graphically intensive games and multi-tasking across numerous apps in general.”
The HTC One was named as the second-fasted smartphone, which has a quad-core 1.7-inch processor and 2GB Ram, followed by the Sony Xperia Z in third, and Google and LG’s Nexus 4 in fourth.
Which? said the phone “will provide plenty of punch for phone owners who use Gmail, Facebook, Instagram and Angry Birds all at the same time.”
The final phones to complete the set were Samsung’s Galaxy Note 2 and the BlackBerry Z10, which came in fifth and sixth respectively.
The fastest phones tend to be the most expensive, costing up to £450 is bought sim free, yet all models are eventually replaced by better and faster ones.
Undoubtedly, Apple will upgrade its next iPhone with an improved processor when it launches later this Autumn. For the moment, Samsung’s Galaxy S4 is the phone to beat when it comes to speed.
According to some rumors, it’s not clear whether the next iPhone is going to be the iPhone 5S or the iPhone 6. Given the iPhone’s history – from the 3G onwards, there’s always been a half-step S model before the next numbered iPhone, so there may appear an iPhone 5S first and an iPhone 6 a while later.
Also it has been uggested that there could even be three size variants of the new iPhone, something like iPhone 6 Mini, iPhone 6 & iPhone 6 XL. Then new handset is expected to be launched somewhere in autumn, probably in September.
