Cook said the iOS update will be rolled out to developers next month.
Apple will release a test version of its iOS software next month that shows users the health of their batteries and will let them turn off a phone-slowing feature meant to prevent sudden shutdowns in iPhones with older batteries, Cook said in an interview with ABC News on Wednesday.
"We're going to give people the visibility of the health of their battery, so it's very, very transparent". This is because performance spikes can require more power than an old battery is capable of providing, which can result in a phone shutting down completely.
Apple faced a wave of criticism after it was reported that the company was deliberately slowing down older handsets to allow ageing batteries to cope with new features and provide smooth performance. Cook said "maybe we should have been clearer", and stated that Apple's motivation behind these types of decision is to always have the user in mind.
The California-based company acknowledged in December that iPhone software can slow down some phones with battery problems and apologised for the issue.More news: Kenya open sales for NY flight
The practice makes sense to maintain the iPhone's reliability, but it's controversial because people didn't know about it and were likely to buy a new iPhone instead of replacing their older iPhone's battery for much less. The CEO maintains, however, that Apple "don't recommend" users take advantage of the ability to disable the slowdown.
He said: "If you don't want it, you can turn it off". Apple's solution to avoid this issue is to slow the phone down. Thus, if the user's iOS device is no longer supported by iOS 10.2 jailbreak, then they might have wait for a new iOS 11.x jailbreak upgrade.
The company has also temporarily reduced the price of replacement batteries for the iPhone 6 and later to $29, starting in late January.
Despite introducing the option, Cook has advised iPhone owners not to turn off the throttling feature when the update is released.
