As the expected release date of the iPhone 5 nears, iFans find innumerable rumors regarding its design, docking port, and display screen. Joining the cascade of rumors is the next hypothesized iPhone 5's battery, which supposedly has got a slight boost.

Pictures posted on 9to5Mac showcase a battery that is expected to be used in the next iPhone. The new battery of the fabled iPhone is expected to be rated at 1440mAh when compared to the existing 1430 mAh battery used in the iPhone 4 and iPhone 4S. The watt-hours rating has increased marginally to 5.45 in the iPhone 5, as opposed to the 5.3 watt-hours of its predecessors. The voltage too sees a fractional increase to 3.8, bypassing the 3.7 voltage of the iPhone 4 and iPhone 4S batteries.

iFans may be wondering why the need for a new battery? It is speculated that the iPhone 5 will sport a 4-inch screen and 4G LTE connection speed. A bigger screen means an enhanced resolution, which in turn implies that more power will be consumed from the battery. Moreover, the 4G LTE network connectivity is also indicative of additional load on the battery.

Naysayers are of the opinion that the slightly enhanced battery may not be able to cope with the new features of the iPhone 5. However, industry experts have a different assessment of Apple's iPhone battery.

"Everybody I have talked to about the iPhone 5 says the battery life will not be a concern. As a matter of fact, the battery life in the iPhone 5 is supposed to be even better than it is on the iPhone 4S. It's funny how people are always so early to make assumptions based on the Internet," said Los Angeles industry analyst Paul Mueller.

Earlier this year, Shaw Wu, analyst at Sterne Agee, expressed a similar view: "Our industry checks indicate Apple has made notable progress in improving battery life that has plagued competitors. This is due to Apple's ownership of core intellectual property including systems design, semiconductors, battery chemistry, and software."

The mixed opinions regarding the iPhone 5's battery may confuse iFans. However, come Sept. 12, iPhone 5's anticipated debut will put any doubts to rest.
