Apple Inc. reported its fastest quarterly revenue growth in more than three years, easily topping Wall Street estimates, after demand picked up for the iPhone and products in China.

On Apple's Q3 earnings call, CEO Tim Cook fielded questions on tariffs, smart glasses, AI investment, and its lucrative Google search deal.

Apple reported strong iPhone sales and rebound in revenue from China, giving a much-needed boost to two parts of the company’s business that had struggled over the past year.
