Apple Inc saw a nearly 10 percent decline in its China revenue in the latest quarter ending in July, as local consumers switched to newer domestic phone offerings and its 10th anniversary iPhone edition is yet to be released to invoke user enthusiasm.

The US tech giant's revenue from China fell 9.5 percent to $8 billion, amid mounting competition from brands such as in the world's largest smartphone arena.

The decline stands in sharp contrast to Apple's overall strong earnings report. Globally, its profit climbed 12 percent to $8.7 billion, and revenue increased 7 percent from last year to $45.4 billion, beating analysts' projections.
