iPhone 6: battery life hopes rise on eve of launch

With Apple expected to unveil the iPhone 6 today evening, hopes are rising that the new model will offer substantially improved battery life.

Super-tough screens, integrated payment systems and a range of health-monitoring apps have all been predicted for the new handset, but potential customers may be just as pleased that Apple is working on something more fundamental – a battery that lasts.

Analysts anticipate that the iPhone 6 will come in two sizes – one, with a 4.7-inch screen that will be available within days, and another, with a 5.5-inch screen, which may not go on sale until later in the year.

Over the past few months, mixed signals have emerged about the likely battery capacity of the iPhone 6, but a consensus is emerging that the larger of the two new handsets will come with a substantially longer battery life.

Owners of existing iPhone often complain that their devices barely make it through the day without needing a recharge.

It's a problem that affects all smartphones to some extent. Phone-makers say customers demand light, slim phones that limit battery size and capacity – as well as big screens and powerful processors, which drain power quickly. By contrast, the simpler, stouter phones available a decade ago could go as long as a week in between charges.

The current iPhone, with its small four-inch screen and slim frame, has less room for its battery than most of its competitors. Unlike Android phones, it also provides no way to see which apps are sapping power, so that users can switch them off to conserve battery life.

Evidence emerged earlier in the summer that iOS8, the new operating system that will debut with the iPhone 6, will give Apple owners that option for the first time.

"A presentation slide shown during the tech giant’s Worldwide Developer Conference revealed the next-generation software will monitor battery usage by app," the Daily Mail reports.

"By monitoring which apps use the most power, Apple users will be able to keep a closer eye on their battery life and know which services to close, in order to extend it."

Previously 9to5Mac.com had reported that the iPhone 6's new processor, known as the A8, will also help to extend the life of the battery.

"Sources say that Apple has developed a new A8 system-on-a-chip for the next iPhone that focuses on marginal speed improvements rather than core architectural changes, but adds significant performance and efficiency enhancements in order to improve the iPhone’s battery life," the website reported.

More recently, leaked specification for the iPhone 6 suggest that both models will feature improved battery capacity, which is measured in milliamp-hours (mAh).

"A capacity of 2,915 mAh [for the 5.5-inch model] would be much greater than that of the 1,560 mAh battery found on the iPhone 5s and the rumored 1,810 mAh battery said to be included on the 4.7-inch iPhone 6," Macrumors reports.
