The deal, with Taiwan Semiconductor Manufacturing Co, will mean the company will replace to Samsung in manufacturing chips in future iPhones and iPads.
The news comes from the Wall Street Journal, which is reporting TSMC will start mass-producing 20nm chips for Apple in 2014, meaning longer battery life in Samsung-less iPhones and iPads from as early as next year.
Samsung will continue to make guts for the next iPhones and iPads until at least 2014, according to the report.
The move follows years of bitter fighting between the two tech giants, including expensive court cases and settlements.
The deal with TSMC will now mean Apple will not have to rely on Samsung at all, while the little-known TSMC is set to reap huge rewards from the mammoth deal.
Apple had reportedly been looking for a deal with TSMC since 2010 when it was looking to invest in the company and/or have TSMC dedicate a factory for Apple chips.
