Apple acknowledges it slows some older iPhones because of flagging batteries

New Delhi: Apple Inc has addressed claims that might be slowing down old iPhones that have low capacity batteries.

Recently, John Poole, the Founder of Primate Labs, wrote in a blog explaining slower performance in the Apple`s iPhone 6s and iPhone 7 models as they aged.

Poole has mapped out performance for iPhone 6S and iPhone 7 over time, and has concluded that Apple`s iOS 10.2.1 and 11.2.0 updates introduce this throttling for various devices.

Moreover, iOS 10.2.1 is particularly relevant, as the update was designed to reduce random shutdown issues for iPhone 6 and iPhone 6S.

Some Reddit users have noticed that the Cupertino-based company might be slowing down the performance of older phones.

So it's true Apple intentionally slow down old iPhones. Proof: My iPhone 6 was bought 3years ago and recently got really slow. APP 'CPU DasherX' shows iPhone CPU is under clocked running at 600MHz.

Meanwhile, Apple has acknowledged that the company does take some measures to reduce power demands - which can have the effect of slowing the processor - when a phone`s battery is having trouble supplying the peak current that the processor demands.

"Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions," Apple told Reuters.

"We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future,” it said.

The problem stems from the fact that all lithium-ion batteries, not just those found in Apple products, degrade and have problems supplying the big bursts as they age and accumulate charging cycles, Apple said in a statement. The problems with peak current draws can also occur when batteries are cold or low on charge.

When an iPhone`s processor makes a big current draw from a flagging battery, the battery can deliver the current in spikes that can potentially damage the phone`s electronics. As a result, iPhones would suddenly shut down to protect the pricey processor from being damaged by the power spikes.

The sudden shutdown problem became widespread among iPhones in late 2016, forcing Apple to issue a software fix that had the net result of slowing the phone somewhat with an old, cold or low-charged battery, the company said.

The problem can be remedied by replacing the phone`s battery. Apple charges $79 to replace batteries not covered under the phone`s warranty. The company has long faced criticism from repair advocates for making its batteries difficult for users to replace on their own.
