iPhone 6s Geekbench battery

Is your old iPhone slow? The problem may be with the battery …

In the past year, many users have reported problems with iPhones 6s battery, which would be shutting down before completely draining the load. Apple, saying that it would have affected only a few units, launched a program to replace the affected batteries for free.

The company later admitted that more users had been affected and said it would release an update to fix that. The result was the release of iOS 10.2.1 which, according to Apple, would have reduced the problem by 80% on the affected iPhones 6s and 70% on the iPhones 6.

What was behind the scenes, however, was what Apple did – and how it can affect device performance. At the Reddit, several users shared results when testing on their older devices, after they upgraded to iOS 11:

Wow, I just installed Geekbench and tried it with my [iPhone] 6 Plus. According to their website, my phone should dial 1471/2476 [pontos] but it actually dialed 839/1377… which would explain why I, like you, noticed that my phone has been noticeably slower lately.

Some speculated that Apple was receiving a lot of battery replacement orders and then released an update to fix the problem. However, others say that this was just a “stop-gap” measure, which lessened battery problems but, on the other hand, slowed the devices down: “Apparently, the way [a Apple] did this by dynamically changing the maximum processor speed in relation to the voltage the battery is producing, so that your phone cannot drain a lot of power and turn off. ”

Everything indicates that the problems are only corrected completely – both the shutdown and the performance of the device – only after the battery is changed, as many users have attested.

It is worth remembering, however, that much of what was reported is not really “defects”. I mean, Apple makes it clear that the batteries in iPhones are designed to last for about two years (it maintains up to 80% of its original capacity for 500 full charge cycles) and that many of these iPhones 6 / 6s may already be naturally experimenting wear and tear over time.

Fortunately, iPhones 7 or later are not affected as they are equipped with A10 or A11 processors, which have a different power management structure (certain cores handle high-intensity tasks and others with low powers).

If you have an old device and it is still slower than normal, maybe everything will work out with a battery change. To test the frequency of your processor, you can use the DasherX CPU app.

Although this is not a novelty, the big case here is that Apple would have intentionally decreased the performance of the devices without revealing it – which has now been “discovered”, becoming a major controversy. We will see if the company takes a stand on the matter, now that it has surfaced.
