Fast Dormancy is a topic we’ve visited before. If you can’t remember what Fast Dormancy is all about, check out XDA TV Producer Erica’s video on the topic, along with the discussion thread. There, you can find a lot of great info about Fast Dormancy, along with XDA Elite Recognized Developer supercurio’s Voodoo RRC tool. Now, the AT&T LG Optimus G has a pretty easy method to disable Fast Dormancy.
XDA Senior Member jonasl has posted a tutorial to get that Fast Dormancy turned off. With it turned on, users may see an unusual amount of wake ups. As jonasl explains:
I’m not gonna go into too much detail, but the offending implementation can be found in com/android/internal/telephony/LgeFDHandlerInterfaceImpl . This class is in /system/framework/com.lge.core.jar . After data activity on HSPA networks they use AlarmManager to periodically wake up and check the number of bytes transmitted over the network interface. This goes on until some time after it stops changing, and the connection is considered dormant.
Thus, a tutorial was written to turn off Fast Dormancy and help the LG Optimus G actually sleep. There are two ways to go about it. The first is some commands entered into Terminal Emulator that turn it off, and the second is an application that will do it for you. So far, users are reporting better battery life. It makes sense, since the device will actually sleep.

Recently, we added forums for various new devices. First up is the HTC Droid DNA. HTC’s late 2012 flagship packs powerful specs, a remarkably high resolution screen, and sleek curves to make any gadget lover drool. Starting with the screen, the Droid DNA (and its Japanese cousin, the J Butterfly) packs the first 1080p mobile phone display. Given the 5-inch display size, this comes out to a remarkable 440 ppi. Not just pretty to look at, the Droid DNA also packs a punch thanks to its 1.5 GHz quad-core Snapdragon S4 Pro, LTE connectivity, and 2020 mAh battery.
Next, we have the Samsung Galaxy Camera. While not a phone, the Samsung Galaxy Camera is an interesting combination of a high-resolution 16 MP pocket camera and a fully functional Android-powered mobile device. On the Android side, it’s powered by a quad-core Samsung Exynos 4412 running at 1.4 GHz. It has a 4.8″ SC-LCD screen, packing a resolution of 1280×720. It comes with a full gig of RAM, and weighs in at a hefty 305 grams. On the camera side, the Galaxy Camera features a 16 MP BSI CMOS sensor. It also features a 28-48 mm (35mm equivalent) optical zoom lens.
Next up are the Desire C and Desire V. Both devices feature single-core Qualcomm Snapdragon S1 processors, half a gig of RAM, and 4 gigs of internal storage. The Desire V’s processor clocks in at 1 GHz, and it features a 4″ WVGA screen. The Desire C’s processor comes in at 600 MHz, and it features a 3.5″ HVGA screen. Both devices are targeted at new smartphone owners looking for a budget-friendly device.
Finally, we have two US Carrier variants of the Optimus G, LG’s late 2012 flagship phone. Powered by the top-of-the-line quad-core Qualcomm Snapdragon S4 Pro processor, the device is certainly no slouch. The speedy processor is backed by 2 GB of RAM, 32 GB of ROM, a 4.7″ “True HD-IPS+” panel, LTE connectivity, and a 2100 mAh battery.
