LTE Galaxy Note 3 to be more energy efficient thanks to Qualcomm chip, report says

Galaxy Note 3

The recently announced Galaxy Note 3 is yet to be tore down in order for curious fans to check out its internals, but a new report says that inside the LTE version there may be an interesting component that will help prolong the battery life of the device.

GigaOM says that the LTE Galaxy Note 3 version contains a “Qualcomm chip called an envelope tracker,” that improves the power-efficiency related to LTE connectivity.

According to the publication, the envelope tracker matches “the power pushed through the phone’s signal amplifier to the actual power needed to transmit a signal.”

To better describe the differences between LTE and 3G when it comes to power consumption, GigaOM offers an apt analogy given by a company that works on envelope tracking technology:

The best explanation was given to [GigaOM] last year by Jeremy Hendy, VP of sales and marketing at envelope tracking pioneer Nujira: LTE is classical music. 3G is heavy metal. Classical music has long quiet interludes punctuated with wild crescendos, while heavy metal is pretty uniform in loudness. Heavy metal is going to sound just as good (or bad) on any amp, but classical music requires much higher power to capture its nuance.

“You need a high-powered amp for LTE otherwise the signal is distorted,” Hendy said. “That’s why the power on an LTE [handset] is so bad. For every 4 watts you put in you only get 1 watt out.”

We’re yet to see battery life tests for the Galaxy Note 3, especially for the LTE version, but we’ll certainly tell you more details about the it in the coming weeks.

We’ll remind you that Samsung will have two Galaxy Note 3 versions in stores, an LTE model (powered by a Qualcomm Snapdragon 800 processor) and a non-LTE version (with an Exynos 5 Octa chip inside). When it comes to battery, the handset packs 3200mAh Li-Ion battery.

The envelope tracker technology is expected to be found in more mobile devices in the future, in order to improve their battery life.

    Sammy leading the battery race. Good news. The Note II had great battery life for a smartphone.

    • AsakuraZero

      nope, if that statement were true, the exynos chips would be more battery efficient than qualcoms, ergo qualcom battery consumption is excellent

      • PopeJamal

        Samsung does, indeed, make the phone in question, therefore, regardless of who created the tech inside, they can be said to be “leading the battery race”.

        Unless there’s some magical Qualcomm phone that I’m unaware of with better battery?

        • AsakuraZero

          Ah… The reply it’s so awful that I don’t even know how to respond to this one.

          Well in your statement assembling a phone is the same as making a SOC or chip gg

          • Grman Rodriguez

            The Note 3 has the biggest battery out of all the S800 phones so far so it is winning…

          • Gilles LeBlanc

            Just think of how iphone still sells, where surounded by idiots and people who have lesser intetest in tech. Choose your arguments wisely as you would with the vagina in your life.

      • Grman Rodriguez

        It’s winning because not only does it have the best chip (the SnapD800) but also the biggest battery, so yeah

        • Bone

          And the best optimization. Often it looks like TouchWiz is so overloaded the HW is struggling, but maybe there’s some lag cause they keep the power at bay… Note II, S4, S4 Mini, S4 Active and a whole bunch of Sammy devices constantly scoring over 60h of endurance rating @GSMA. Sammy knows something.

          • Grman Rodriguez

            I disagree with you on that. If the battery lasts a month but comes with the compromise of laggy and stuttery experience then it’s not well optimized
            It’s like an F1 engine, is the most fuel-efficient the one that can only go 20 miles/hour? No, right?

  • Gilles LeBlanc

    Just 200mHa better then experia Z Ultra??? Whaeva I do what I want, I’m buying Z Ultra :-)

    • TheDoucheLeBlanc

      LOL nobody gives a F about what your going do

    • asian101

      Congrats. I bought the Z Ultra also.

    • dfq

      zu is way too beautiful to be compared to galaxies but it’s admittedly less preferable when it comes to the battery and features.

      sony should learn to make a complete package. it’s time to stop being too obsessed on beauty and durability.

      i really expected so much from the zu because i thought it would adopt the touchscreen tech they use on their e-readers—that thing that enables touch that seemingly detects pressure and the width of the object touching the display. i also thought it would include the IR LEDs on the side to allow the device to be controlled by gestures from the sides.

      • Gilles LeBlanc

        I agree, Ive given this much thought cause its such an important tool in my life. Im really curious to know what ur buying? Do tell and also elaborate why please and what your using now :-)

    Give us News on the HTC Max. now the note 3 is old already 2 days old LOL

    • scb1898

      Ancient phone! Gimme the next new device!

  • samy

    Gsmarena battery score for Note2 (3100 mAh ) is 69, for Z Ultra is 52!. Because zultra has a huge 6.4 screen and has the WORST battery for its size, and its NOT removable!. And has only 8mp camera with NO flash.

    • asian101

      Absolutely spot on comment. But there are features (which maybe are minor to you but major to some) that the Galaxy Note series doesn’t have as with the Z Ultra.

  • Mohd Danial

    Hoped they do somethin in the 4.3 update… my lte coverage is quite poor

  • PopeJamal

    Good News all around!

  • SuperLONGstick

    what about the screen tech? Sammy never used the same kind screen from flagship to note series before… rgb stripe usually brings in battery saving features as well as more space and brightness.

  • Shivram.K

    India is getting the Exynos chip… does this have a FM radio ?.. Why this discrimination…India does not get the S 800 chip with the above feature, no 4K recording & same price…very sad

    • indiaMEH

      who gives a f about what happens in india its a 3rd world

      • raghu

        India is the second largest market to samsung after china….

  • Blowntoaster

    I’m hoping the Octa version will be just as good on power effeciency…
