Leaked photo hints at A5 iPhone 4 revamp

A leaked photo has prompted speculation that Apple plans to launch a new iPhone 4S at the same time as it outs its upcoming flagship iPhone 5 in October.

The new image, which has surfaced on Chinese blogging site Weibo, shows a logic board with an ARM-based A5 processor in place - the type expected to appear in the new iPhone 5, as well as the handset's battery and other components. Slightly less expected is the appearance of what looks the fascia and LED display that look suspiciously like that of the existing iPhone 4.

If genuine, the image is a bit of revelation: Apple usually reserves its cutting-edge components for the company's flagship products, and a souped-up iPhone 4 including the speedy A5 processor could perhaps even impinge on the market share of its soon-to-be-released iPhone 5. Either that, or it points to a change in policy away from what Apple has traditionally always insisted: that it will never create a 'budget' version of its top-selling smartphone.

Also prompting some debate are the specs of the battery in the shot. It appears to be the same model as seen in previous photos published by MacRumors - but instead of the earlier battery's 3.7V and 5.3Whr rating, which would yield a charge capacity of around 1430mAh. The newer picture indicates a voltage of 4.2V. For comparison, the current iPhone 4 battery is rated 3.7V and 5.25Whr, offering 1420mAh of charge.
