Apple's iPhone 5 runs on the new A6 processor, aimed to make the smartphone runs twice as fast compared to the iPhone 4S, but will that affect its battery life?

During the iPhone 5 keynote on Sept. 12, Apple Inc. Vice President Phillip Schiller showed how the batter life is improved in the iPhone 5.

He detailed 3G talk time and 3G and LTE browsing will have up to eight hours of usage, Wi-Fi browsing will be able to withstand 10 hours, video is also at 10 hours, 40 hours for music fans, and 225 hours on standby.

Reviewers have tested those times, and Latinos Post has gathered a few up.

Jeremy Horwitz of iLounge stated that as much as he wants to proclaim the iPhone 5 as an "all day phone" it turns out "it's still not."

He added, "just like most of its predecessors, Apple prioritized new thinness and speed over battery life. Consequently, it's advisable to keep a charging cable nearby, lest you find yourself out of juice at or before 5pm."

Horwitz noted the battery performance "too often falls below Apple's case estimates," especially when used for calls and data.

iLounge's test concluded that the Wi-Fi browsing lasted a little over eight hours, but far behind Apple's statement of 10 hours. LTE browsing, under Verizon, lasted about five hours, while under AT&T lasted between four and five hours. Those times are short compared to Apple's eight hours.

Laptop Mag's Mark Spoonaur also conducted some tests and compared it to other devices.

Spoonaur's test saw that the iPhone 5, on wireless, last for seven hours and 13 minutes. He compared the time to the iPhone 4S and Samsung's Galaxy S3, and the iPhone 5 is victorious compared to them. The iPhone 4S lasted five hours and 54 minutes while the Galaxy S3 lasted six hours and 55 minutes.

While speaking to NBC News, Spoonaur said, "For the [battery] size, I think that the iPhone 5 offers fairly good battery life."

The iPhone 5, which has a battery capacity of 1,440 mAh, however lost to the Droid RAZR Maxx, due to a battery capacity of 3,330 mAh, lasting 8.5 hours.

There are a few methods to save your battery life under the new iOS 6, courtesy of iDigital Times. Turning off Wi-Fi and Bluetooth helps, otherwise it will constantly run as it searches for wireless signals.

Another way to ease on battery life usage is to limit the notifications. For every notification used, your phone lights up, wasting some valuable energy. While there is no direct disable button for notifications, iDigital Times noted: Go to: Settings > Mail, Contacts, and Calendars > Fetch New Data. Disable push e-mail and set "Fetch" to manual. You'll have to check your e-mail yourself, but this gives you a little more control over how your phone spends the precious, precious battery power.

There is also the recommendation for the CARAT app which sends a report to you on which apps and features you don't use and how much in battery life you'll save once those get disabled.
