Multitasking/running apps may help deplete batteries on iOS-based devices

When Apple released the iOS 4 update, people noted significantly lower battery life on a number of iOS devices. In troubleshooting the problem, it became apparent that Wi-Fi usage was in large responsible for draining the battery, and initially the recommendations were to disable Wi-Fi features.

Per CNET, users may find the device losing battery power if you keep multiple applications open when you put the device to sleep.

MacFixIt reader R.T. Taylor wrote in with a little clarification on the issue:
“Each programmer is responsible for turning on or off multitasking. And evidently they are not paying attention to that tiny detail. That is how you can have a multitasking job running in the background for a flashlight app.

To see what is running in the background, press the home key twice. You will see up to four background apps in the bottom of the display, scroll right to see what else is running. Mine had about 50 apps running.”

Having multiple applications running at the same time will obviously drain the battery to a greater extent when the device is in use, but when the device is in sleep mode, the applications should be suspended; however, people have found that quitting them all before putting the device to sleep seems to solve the low-battery-life problem.

It is possible that even though the applications are suspended, their being active when the device is put to sleep may prevent some hardware components such as the Wi-Fi adapter from being put to sleep at the same time. This may result in items like the Wi-Fi adapter staying active during sleep, and may also be a reason why when people specifically turn off Wi-Fi before sleep, that the battery level no longer drains rapidly.

Most people run applications and then press the home button to quit them and run alternative applications, but this does not fully quit the application. Instead, if you want to fully quit an application, press and hold it until the icon jiggles, and then press the X and the full application process will shut down.

As always, the peanut gallery is open for business and let us know what’s on your mind.

TSA to allow 11.6″ MacBook Air to remain in bags during security screenings

Good news for travelers: Your late 2010 11″ MacBook Air notebook will note have to be removed from its bag at security checkpoints in U.S. airports, the Transportation Security Administration has announced.

Per CNN, TSA spokesperson Nicholas Kimball has stated that the new 11″ MacBook Air is small enough that it doesn’t need to be removed from a bag when going through an X-ray machine at airport security. Larger devices, including the MacBook Pro, must be removed from a bag when being scanned so that TSA officials can get a closer look at the internal components.

“If someone has a lot of stuff in their bag, it’s sometimes difficult to get a clear view of it,” Kimball reportedly said. “It might need some additional screening.”

TSA has not yet made a decision on the larger, 13″ MacBook Air, which means travelers will likely have to take the notebook out of their bag for the time being. But the larger MacBook Air could be exempt in the future, because it also lacks an optical disc drive, as well as a traditional hard drive.

Apple’s new 11.6″ and 13.3″ MacBook Airs were unveiled earlier this month, and the larger model weighs just 2.9 pounds. Both devices rely on flash memory for storage, making the hardware smaller and faster than a traditional laptop.

Earlier this year, when the iPad launched, TSA announced that fliers could leave their iPad in a carry-on bag when going through security. The minimal amount of components inside the iPad makes it easier for security officials to analyze in an X-ray machine.

Officials can, however, ask a traveler to remove their iPad, MacBook Air or any other electronic device if they cannot get a clear image of it in an X-ray scanner.
