Amount up $425M year-over-year
Apple's spending on research and development jumped 36 percent year-over-year in the June quarter to $1.6 billion, according to the company's latest 8-K filing with the SEC. That brings the company's R&D totals for fiscal 2014 so far to $4.36 billion, 32 percent more than it spent during the same timeframe in 2013. The pacing of R&D has also accelerated throughout 2014.
The company is typically tight-lipped about its research efforts, but has likely been working on technologies set to premiere in the iPhone 6 and iWatch this fall, as well as long-term projects aiming a year or more into the future. Devices like the iPhone and iPad began development years before their official announcements.
