Huge LTE Radio Energy Consumption Improvements Loom
Particularly Addressing Battery-Eating VoLTE
by Karl Bode 08:51AM Friday Jan 04 2013
Next-generation LTE radios are expected to trim back energy consumption by 50%, a needed energy savings for power-hungry smartphones and carriers eager to embrace Voice over LTE (VoLTE). According to a new whitepaper released by ST-Ericsson, a slew of design improvements should be responsible for those battery savings, particularly addressing the current problems with VoLTE. Numerous recent reports have highlighted the huge battery drain of VoLTE, largely due to the lack of active dual-mode operation (current devices have to constantly flip between CDMA 1X and LTE networks). As a result, most companies pushed their VoLTE deployments well into 2014.

still

I still say they will remove the unlimited voice when this comes out due to MadeUpReason_0-111-3 in their plan book. HD quality over the crap we have now shall be at a premium..

Trust me these guys are pricks, and pricks like money, more money than deserved.. HD voice has been available in other countries for years now, but they will make it out to be something brand new with the kung fu grip

Glad we went LTE

This is the beauty of GSM, as they are constant making improvements. Whereas, CDMA has only made a handful of improvement since launch.

Look at EVDO Rev A 3.1mb versus 42mb HSPA+ for example.

Re: Glad we went LTE

Yep, GSM/HSPA/LTE is also a lot more power efficient than cobbled together CDMA + LTE. especially when you want simultaneous voice and data.

That's why Sprint and Verizon need VoLTE much faster than AT&T and soon T-mobile when they deploy LTE.

But this advancement is great, any optimization they can do to make LTE radios drain our phones faster will benefit everyone.

Anyway who cares. Verizon will be dumping it's 1x and 3G within 8 years. Then they'll be 100% LTE by then.

More Power

You would think that the power consumption of a VoLTE (LTE)call would be lower than having to use two chipsets (CDMA/LTE or GSM/UMTS/LTE). It would be like saying Skype voice calls over LTE are a battery killer.

VoLTE: OTT Service Killer

From the last paragraph of the whitepaper:

Another final, albeit interesting, observation is that over-the-top services like Skype are forced to run in the power-hungry application processor (since they are apps) and have no help from advanced protocols; consequently they will be increasingly disadvantaged versus VoLTE. Something they are not today.
...hah. Any bets on whether or not Google/iOS will open up the relevant subsystems to OTT apps?
