Rumor has it that Apple's next-generation smartphone, the iPhone 7, will use the type of battery that can be found in iPhone 6s. Several reports claim that Apple is planning to reuse the old battery primarily to cut the production costs for the said device. By doing so, the Cupertino-based company will be able to fund and develop technology in other parts of the smartphone, a report from iDigital Times said on Tuesday.

"The iPhone 7 is rumored to deliver a range of new tech. Projected specs include an A10 system on a chip (SoC) that will sit at the heart of the smartphone and a super thin frame at 6mm thick. The iPhone 7 might also have a 2K display, an Apple wireless charging puck, front-facing speakers, and an 8MP selfie camera in the front," iDigital Times said.

"The latest reports from close to Apple indicate that iPhone 7 fans hoping for an increase in battery life will ultimately be disappointed. Murmurings from close to the Apple supply chain this week suggest that the forthcoming handset will stick with the existing battery-sapping displays that Apple already utilizes, as well as not featuring a significant increase in battery size," Valuewalk reports.

The recent rumor about iPhone 7 suggests that the device will have a strong and a waterproof non-metallic body.

However, according to Bidnessetc, "Apple wouldn't want to take away the premium look from its most-treasured product. We expect the iPhone 7 to be similarly priced as the iPhone 6s, and not many would want to shell over $649 for a device featuring a poly-carbonate body (a different way of saying plastic)."

"The A10 chipset is believed to be far more powerful and power-efficient than the current A9 chipset that powers the iPhone 6s. So, expect the smartphone to provide a better battery life when running on the 1,715mAh unit," the report said.
