Adrenaline Engine 4.4 for Android : Script to Supercharge your Galaxy Phones


Adrenaline engine 4.4 for android is yet another script for android galaxy series phones to supercharge the device with rocket speed. I had shared another script, SlaidyBoost for Galaxy mini some days ago for the same purpose. Adrenaline engine is a specially designed script to enhance overall performance as well as battery backup.

Adrenaline Engine android seems to be the most anticipated script so far and it has been downloaded by millions of Galaxy phone users. As usual, this script is also created by one of the geeks at the XDA forum, Yash98. I have 2 android phones which are Samsung galaxy mini and Galaxy SII. I had flashed Adrenaline engine in my galaxy mini before months but never tried with Galaxy SII. To my surprise, the result was outstanding and it has brought my phone to the next level.

The adrenaline engine has tremendously improved my battery backup by minifying RAM usage and CPU overload. It also helped to fix Tons of prop tweaks that were pushed out due to the CyanogenMod 10.1 update. Though the CM 10.1 for Galaxy Mini/Ace is stable, it still lacks some prop edits, mainly in overlay fields.

Adrenaline engine was originally made for a few devices say Galaxy Mini, Ace, Gio, etc. But after getting so many user requests, the developer has made it compatible with some more phones like  Xperia Miro, Tipo ,Tipo (Dual) etc.

Adrenaline engine 4.4 is probably the last version of this series since the developer isn’t interested to create further changelogs. However, it’s enough for optimizing your galaxy devices. I can give you a top guarantee that you won’t be disappointed by using this awesome script. It works just like Slaidyboost but Adrenaline has got much more tweaks and functions.

  • Hi Siddharth,

    Many people are complaining that the Gmail app and Camera are not working in the Adrenaline Engine….. This is what it stops me from trying it on my device.

    • But Naser I have been using this script in 2 of my phones which are Galmin and S II but didn’t face any problems at all. They might have tried the earlier version of this script which had some bugs. Trust me, it really works without any problem. Thanks for letting me know your opinion and let me know if you have tried this then.

  • Hey Sid. Great info about Adrenaline. I am using HTC Explorer running android 4.2.2 (CM10.1). Is this adrenaline engine compatible with my device or is it just for the Galaxy? Do let me know 😉

  • hi buddy
    i m using sgs gt i9000. updated it to latest 4.4.2 kitkat running cm11 .. can i install this ?
    i tried to install pureperformce mod rom but it wasnt working perfectly in my phone..
    do i need to install busy box ? why ? and also i need to install uninstall file also same time when i copy this ardenaline engine to phone ? cant i reboot in cwm if any thing goes wrong and flash my back up again ?

    • Hi Kaushik,

      Thanks for dropping by, You can certainly use Adrenaline Engine, you don’t have to install busy box, just go through the procedure in the post. You can also reboot in cwm to back up.


      • thx buddy .. surely going thro it now.
        can u give one reco. for a budget phone.
        which one is better to buy moto x or micromax knight 350 if it gets kitkat update

        • Hi Kaushik,

          Well, wait for some time until Micromax Knight gets released. Check out for it’s reviews, it’s build quality. I guess you should get moto X, I think knight might get a poor build quality than moto X.


          • thx buddy .. just wanted to see micromax as it looks like unibody design .. but havent seen yet in real .. yeah moto x is anytime better .. i wld have gone for nexus 5 but thing is i feel its slightly larger in size .. so avoiding it ..
            one more thing.. its been long i flashed last time .. its a funny question but still have to ask .. do we have to unzip files in computer first and than tranfer or tranfer as it is in phone and just run it ..sounds funny but m really busy in other work so forgot all how i flashed old..
            u din said me do i need to install busy box or flash directly ?

          • Hi Kaushik,

            You don’t need to install busy box, flash directly. Moreover, you don’t have to extract and then flash, flash the zip file.

            I hope it helps,


  • Hey friend i did flashed file on sgs gt i9000. i just cant belive it has turned my phone to super phone .for Battery life i hv stopped worrying now .its lasting double of what it used to .wifi working faster . its super crazy .so much to say .not writing all. works exactly as its written. full marks to u & yash . whole 250 mb file of 4.4 version which can not do is been done by this 1 mb small file ..amazing
