android l release performance graphics battery

Google is previewing the Android L release, due for the fall, on stage at Google I/O, and one of the big components of the new OS is improvements coming to the performance and battery life of Android devices.

L release will be the biggest release ever for Android; in the performance department, Google will – as rumored – enable ART as the default runtime in Android L, replacing the aging Dalvik. Thanks to ART, which supports features like Ahead of Time compiling, Just in Time compiling, and interpreted code, Google can offer a performance jump of 2x compared to Dalvik.

Android L will also feature better memory collection, meaning that the system will be able to make better use of the available memory. As expected, L will bring the jump to 64-bit, with ARM, Intel, and MIPS platforms supported. 64-bit will bring benefits like more registers, newer instruction sets, and increased addressable memory space. This should help with general performance and battery efficiency.

In terms of graphics performance, L will support features like tessellation, geometry shaders and computer shaders, as part of the so called Android Extension Pack.  Google claims that the AEP will improve graphics to levels comparable to PC quality, as a demo of an Unreal game showed on stage.

Finally, battery life will be improved as well in the L release, thanks to features like a new battery saving mode, scheduling of maintenance tasks, and coalescing of CPU tasks. Project Volta will give developers tools to monitor battery consumption and correlate it with CPU actions. According to Google, battery saving mode can add up to 90 minutes to a typical day of usage on a Nexus 5.

Google is also promising 5000 APIs for the L release, including APIs for Bluetooth 4.1, burst mode, USB audio and much more.

Google will be releasing a developer preview of Android L release tomorrow, along with firmware images for Nexus 5 and Nexus 7.

Stay tuned for more details.

    KitKat was supposed to work better on devices with less RAM yet I’ve never seen any evidence of that.

    • Daniel Collins

      It does, it can work on devices with 512mb of RAM, and works on the minimum of 340MB.

    • patrik

      Haven’t you seen moto g and moto e?

    • MasterMuffin

      Again commenting the same thing. Still not true

      • Luka Mlinar

        Phones that run like crap because of lack of RAM on JB still run like crap on KitKat.

        • MasterMuffin

          There are multiple reasons why a phone runs slow, not just lack of RAM

          • Crutchcorn

            And that’s exactly what Google has said. That’s like saying Project Butter didn’t do anything

    • Crutchcorn

      What about android wear? That’s just a scaled version of KK and thus makes it legit that 512MB systems very well

    • Ramy

      well it does…on my note 3 now i only use 1gb of rams and have 2gb just sitting there wasting there time lol

    • Blue Sun

      This was always intended for devices in 3rd world & emerging markets.

    • Jaime A.G.

      Because phone makers still put crap-UI layers which take half the resources!!!

  • patrik

    I am so happy right now!!

  • Daniel Collins


  • Marius Messerschmidt

    Wow, tomorrow ;-)

  • PhoebeCDonmoyer

    Finally, battery life will be improved as well in the L release, thanks to features like a new battery saving mode, scheduling of maintenance tasks, and coalescing of CPU tasks.

      This is pretty big for me too. My fav announcement of I/O so far.

  • MasterMuffin

    This is the iOS7 of Android world. Not hating, it’s awesome!

    • Luka Mlinar

      Dude how come you’re not on the AA forum? I figured you would be the first one to join there.

      • MasterMuffin

        Never liked forums. XDA is enough for me

    • Crutchcorn

      It’s SO MUCH MORE than the iOS 7 of Android.

      • MasterMuffin

        Well let’s say it’s the combination of iOS7 and iOS8 for Android!

        • mobilemann

          iOS 8 is 5x the size of iOS 7. Under the hood > eye candy!!!!

          • Crutchcorn

            Which is why it’s the jump from Android 4.4 -> L = iOS 6 -> 7 & 8. Android L brought SO MUCH backend stuff (AND FEATURES) on top of the eye candy!

        • Crutchcorn

          THERE we go.

  • jirokanz

    What sweet start with L?

    • Sunny


  • Alex James Simon

    I think they announced Android L a little early so device makers (Samsung, HTC, etc) have time to maybe get it released in the Fall alongside Nexus devices. The version tomorrow is a developer build.

  • Crutchcorn

    Glad to hear! L has many many improvments much needed!

  • nikhil dalmia

    Providing the developer preview for nexus 5 and 7 only means no L release for the nexus 4??

  • shaynej95

    What devices will this be for ?…..I’m still waiting for KitKat for the Note 2 from at&t……..smh

    • alex0000000001

      I’m sure you’ll have to buy new devices for it. Still no ART on the nexus 10.

    • Jay Hova

      It’s going to be more for new upcoming devices to take advantage of all the new features especially leaving dalvic to art. And the 64 bit chips, and the note 2 prob won’t make it past kit Kat if your lucky unless you root. Well we might get the L update it won’t truly take advantage.

  • Anonymous

    The new “back, home and recents” buttons are just so ugly, omg.

  • Dr. Steve

    So did they drop the dessert theme? I feel like past announcements actually used the final dessert name (eg kit kat)

    • Guest User

      The name is yet to be announced. It just the series letter L has be mentioned so far.

  • John A

    This all looks very good indeed.

  • Alex Zhao

    Every year new version of Android claim huge performance improvement. Wonder what they say next year.

  • Zachary Yeh

    Which Nexus 7 is getting the preview?
