Apple has addressed claims from an app firm that says the maker of iPhones slows down the operation of older phones.

On Monday, the site Primate Labs, a company that makes an app for measuring the rate of an iPhone’s processor, published data that appeared to reveal slower performance in the Apple’s iPhone 6sand iPhone 7 models since they aged.

Apple on Wednesday acknowledged that the organization does take a few steps to decrease power demands – which can have the effect of slowing the chip – if a phone’s battery has trouble providing the peak current that the processor demands.

The issue originates from how all lithium-ion batteries, not just those located in Apple products, degrade and also have problems supplying the huge bursts as they age and collect charging cycles, Apple said in a statement. The problems with peak current draws may also occur when batteries are low or cold on charge.

“We have now expanded that attribute to iPhone 7 with iOS 11.2, and plan to add support for other products in the long run.”

When an iPhone’s processor makes a large current draw out of a flagging battery, the battery may deliver the present in spikes that has the potential to damage the phone’s electronics. As a result, iPhones would suddenly shut down to protect the pricey processor from being damaged by the energy spikes.

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

The problem could be remedied by replacing the telephone’s battery. Apple costs $79 (roughly Rs. 5,000) to substitute batteries not covered under the phone’s warranty. The business has long faced criticism from fix advocates for making its batteries hard for users to substitute on their own.
