Remember a few months ago when fellow Android enthusiast Amit was sick and tired of his phone's performance being subpar? Google took notice by marking his issue as "FutureRelease," thus ensuring that one day, the Performance Boosting Thing™ that he so desperately desired would see the light of day. Well, folks, that day has now arrived. The bug has been marked as "Released" and Amit's problem is now officially fixed.


Considering that Google just released Android 4.4.4, it would seem logical to conclude that PBT™ was included in that release. If you don't have a Nexus or another device that stays on the bleeding edge of Android OS releases, just hang tight. As more and more manufacturers update their phones, you too will likely be able to benefit from this amazing breakthrough in performance.

Update: During an ART talk at Google I/O, the following slide was shown to attendees, proving that PBT™ and the new Android Runtime (ART) are one and the same.

    I feel bad for the people with a Nexus 4, not being able to experience the
    Performance Boosting Thing™ yet.

    This is why y'all bought a Nexus device, isn't it?

    • saf1927

      Nexus 4 does have 4.4.4 already. The fix, if ever released, was on 4.4.4, since Android L isn't officially released on any device yet.

      • http://www.flickr.com/photos/77537273@N03/ Herman

        Damn, I can't wait for the 4.4.4 update for my Xperia Z1. I don't care about Android L anymore, I need this Performance Boosting Thing™!

  • Arcest

    I though there was an Xposed module for that.

  • Cesar

    do you guise have apk download for performace boosting thing?


    • Harrison Haley

      It would be in Android 4.4.4 you dumb idiot. If you don't have a nexus device than you could root your phone with cyanogenmod. They have included android 4.4.4 in their nightlies.

      • Anthony

        Is there such a thing as a smart idiot?

        You're out of touch.

        Love the guys that thinks he knows everything yet knows nothing at all. Douche.

      • NexusKoolaid

        You must be new here. If you'd been around a while you would have recognized this as a joke and where the joke came from.

        Just saying - It's usually a good idea to hold back on the insults and name calling because they they tend to come back around at you. Like what just happened with your post.

      • blumpkinator

        4.4.4 has been released to GPE devices. My GPE M8 has it.

        It's not just Nexus...

    • Benjamin Pavel

      LOL that "SOON BACKANSWER" is very familiar...where is it from again? :D

    • dude

      I think ART is the main part of the performance boost in Android so it's good it's good they finally let go of Dalvik, especially in light of the Oracle litigation.

      • verboze

        Yup. The move to ART was inevitable, given oracle's persistence with its lawsuits. It sets google in a much better position with its partners in terms of android's future when they don't have to worry about oracle coming back and collecting royalties.

        • Darwin

          Exactly. They knew they could not get away with stealing Dalvik much longer.

        • MarkG54321

          How does this affect that? You still write code in Android using Java API's That's what the lawsuit was about...

          Davlik is OpenSource (and not created by Google).

    is this the kind of bug report voice/hangouts needs?

      If I could grammar like that, I would totally do it. But alas, I cannot.

  • Simon Belmont

    Android 4.4.4 boosted my signal strength. It also seemed to boost the RAM that is free.

    PBT x2. Awesome.

  • Zach Mauch


    PBT = ART

  • Tarun Pemmaraju

    They fixed the old KitKat battery percentage thing too, guys! Use the app in the Play Store to activate it. You can now read it at all stages.

    • http://www.androidpolice.com/ Artem Russakovskii

      Thank fucking god.

      • mlj11

        That's my favourite god too! :D

      • Tarun Pemmaraju

        I wonder why they haven't added an official setting yet though.

        • http://www.androidpolice.com/ Artem Russakovskii

          Yeah, makes no sense. The Android team doesn't like settings, they want everything to just work like magic without having to tweak it, but I think that's a mistake in this case. Just keep it disabled, but give us an option to turn it on like all the ROMs do.

          • Bluewall

            The problem is, in L, the percentage is really hard to read. Just let us, as every other phones on earth, add a percentage near the battery icon. PLEASE.

          • sam

            I guess Google don't want you reading the percentage? I know when I had it in the notification bar, I worried about it more. 25% seems like not much, but it's just that: 25% left, which is actually a lot. I very rarely run out of battery in one day on the Nexus 5, but I'm always worrying about if the battery percentage is lower than it usually is for this time of day etc.

            In L, the battery percentage is gone from the lock screen while charging and from quick settings, being replaced with an estimate of how long to charge or discharge. The percentage is ONLY in battery stats now. I like this: I expect I'll worry less.

          • WhyDoesEveryUserAlreadyExist

            It's even more misleading since L will enter battery save mode at 15% and last much longer from 15->0.

            OTOH The predicted times are a bit crazy at the moment.. Battery stats are saying I've used 8% of the battery in 9 hours, and I have 4 days left. Nexus 5 just doesn't last that long... I'm having a hard time believing anything battery related in this release.

    • Josh

      Excuse the ignorance, what app are you talking about?

    • PaulMonroeJr

      What app is that?? I'm not being sarcastic, but I installed a battery percentage app but its still white like the battery icon. What's the exact name of the app?? Cause I'm using battery percentage for KitKat...

  • soon_backanswer

    but but 4.4.4 was just a security release

  • Tarun Pemmaraju

    You can go back to ye olde keyboard in the keyboard advanced settings.

    Milarious!!!!!! SO funny it gives me Malaria!

  • djakdekiel


  • Fatal1ty_93_RUS

    Wow, much performance, so boosting, very thing

  • scuttlefield

    I didn't notice any performance improvements with 4.4.4, but yesterday after I updated Play Services and Google Now Launcher but my N5 and N10 seem a Llot smother. Although, I've been wondering if it's just placebo effect.

  • Daniel Marcus

    Actually, my guess is that it referred to making ART the default runtime. Since that was officially announced yesterday, the timing makes a lot of sense.

  • Esteban Méndez ⚡

    Ask? Well, we need Android L for N4 and N7 (2012) please!

    • Matthew Fry

      And N10

  • Joseph Lampke

    Can we please stop it with le rage maymays?

  • Björn Lundén

    Based on all the talk about performance improvements in L, it clearly refers to that release and not 4.4.4 which is only a security update.

  • PaulMonroeJr

    Well I switched over to ART about 3 or 4 days ago (I have a Nexus 5 on 4.4.4) and the "lag" people always talk about on android devices, is completely gone. I used to notice lag when I would go from WiFi to LTE, then I would get some lag. As soon as I connected back to wifi, it would be mostly gone. But now?!?! ART really does boost performance and take away that lag that people always associate with android phones. I'm just wondering if it will do the same for phones with skins ie: Touchwiz, Sense, etc, etc.

  • dontsh00tmesanta

    Does anyone notice a difference between ART and dalvik on their One M8?
