New data supports claims that iPhone 6S performance is poor until old battery is replaced, sparking fresh speculation that Apple intentionally slows lower phones

A brand new analysis of performance data has reignited the controversy over whether Apple intentionally slows down older iPhones.

The information suggests Apple cuts down on the speed from the processors in iPhones with old and worn batteries, which makes them slower.

Following user reports that older iPhones with ageing batteries performed worse compared to same smartphones with substitute batteries, founding father of benchmarking firm Primate Labs John Poole collated data in the companys Geekbench program that’s operate on a large number of iPhones.

He discovered that results from benchmark tests in the iPhone 6S running iOS 10.2 pooled round the expected performance peak showing exactly what the iPhone 6S was able to with no hindrance.

But from the development of iOS in The month of january 2017, the information demonstrated five peaks the very first matching the utmost performance just like iOS 10.2, however the following four at relatively set times showing steps downwards in performance.

Exactly the same was seen with tests operate on the iPhone 6S running iOS 11.2, that was released in December 2017.

Poole authored: The distribution of iPhone 6S scores for iOS 10.2. seems unimodal having a peak round the average score. However, the distribution of iPhone 6S scores for iOS 10.2.1 seems multimodal, with one large peak round the average and many smaller sized peaks around lower scores. Under iOS 11.2. the result is much more pronounced.

iPhone 7 also affected

The outcomes for that iPhone 7 show an identical pattern. With iOS 10.2, 10.2.1 and 11.1.2, the iPhone 7 results show one large peak in the average maximum performance expected from the smartphone. But iPhone 7s running iOS 11.2 then show one maximum peak adopted by three smaller sized peaks.

The distribution of iPhone 7 scores under iOS 10.2., iOS 10.2.1, and iOS 11.1.2 seems identical. However, the distribution changes with iOS 11.2. and begins to seem like the iPhone 6S distribution from 10.2.1, authored Poole.

According to Reddit users, who first reported the problem, the reason for the performance differences is due to degrading batteries. Photograph:

According to Reddit users, who first reported the problem, the reason for the performance differences is due to degrading batteries. As a smartphone ages, as does the battery inside.

Most modern lithium-ion batteries inside smartphones are designed to last at least 500 full charge and discharge cycles, which works out to around two years of typical smartphone use.

However, the shorter the battery life and the more a user has to charge it, such as topping up during the day as well as charging over night, the faster the battery will age in relation to the smartphone.

Two key things happen when a battery ages. The first is that its maximum capacity is decreased due to the degradation of certain chemical components inside the cell caused by each charge-discharge cycle. But that oxidation also causes the maximum current the battery can supply to diminish as the battery becomes less efficient.

The first means that you have to charge your phone more, but the second means it may not be able to maintain top performance, as the harder the processor and other components have to work the more current they draw from the battery.

Fixing issues

In November, Apple began replacing batteries in some iPhone 6S models due to problems where the phones would suddenly shut down despite having about 40% charge remaining in the battery.

It later issued a software fix for the problem as part of iOS 10.2.1 for that iPhone 6S.

Poole authored: The distinction between 10.2. and 10.2.1 is simply too abrupt to become only a purpose of battery condition. In my opinion (just like others) that Apple introduced a big change to limit performance when battery condition decreases past a particular point.

Reddit users are convinced that replacing worn batteries alleviates the performance degradation, restoring the iPhone to the original speed.

Developer TeckFire said: I did a Geekbench score [with an iPhone 6S], and located I had been getting 1466 Single and 2512 Multi. This didn’t change whether I’d low power mode off or on.

After altering my battery, Used to do another test to see if it had been only a placebo. Not a chance. 2526 Single and 4456 Multi.

The lower performance also seems to modify the newer iPhone 7 by iOS 11.2. Some have speculated that Apple dynamically reduces performance of older iPhones with regards to both battery put on and current charge. The information from Geekbench signifies that there’s several reduced performance condition.

Poole stated users expect their smartphones to do either at maximum performance or in a reduced performance having a reason, for example when low power mode is activated.

When the iPhone is slow because its processor performance continues to be reduced to mask an insufficiency in electric batteries, Poole states: This fix may also cause users to consider, my phone is slow and so i should replace it not, my phone is slow and so i should replace its battery.

This will probably feed in to the planned obsolescence narrative.

Apple hasn’t responded to some request to comment when of publication.
