Root booster is for root users who need more performance to run applications smoothly without lags or for those who need to improve a poor battery life

There are many apps that save battery or increase performance, however Root Booster uses the most proven  settings to achive the best results. You can easily apply these settings with preset modes which ensure speed boost, battery boost or stability boost. These modes are achieved by applying appropriate settings to the main phone components. Here are some explanations for what particullary Root Booster does to your CPU, RAM and Android OS system. 

Hibernation (Android OS optimizer)

Each Android application can have  one or multiple services. They run in the background and usually perform some kind of task. Many people think that when they kill an application,  it completely stops draining your battery and computing power, but that's not true.  Application still have servicies that are running after killing and  still drains battery and comuting power.  On the other hand, if you hibernate an application it stop it's servicies and application does not drain battery and CPU computing power anymore. Hibernation is gently and efficient way to save your battery and increase performance.

 Root Booster will find battery draining and performance demanding applications and auto hibernates them.

CPU (processor governor control) 

A governor is a driver for the  regulation of CPU frequency. Governor decides how fast and when will be achieved maximal or minimal CPU frequency. Setting apropriate governor makes your device more battery saving, fast or even more stable. However, deciding which governor is suitable is a little bit tricky. 

Root Booster can decide which governor you should use and automatically applies the most suitable governor for the selected mode.

RAM (memory manager)

Each application uses VM heap for it 's data and work. The main reason to change the VM heap size is stability improvement. Many big applications need a big amount of memory (VM heap) for their work. If the VM heap size is smaller than the requested memory, it causes an application crash (Out of memory error). Setting heap size is hard task and there is no manual to set up for better performance. Better performance can be only achieved by testing. 

Root boster will test your RAM and sets up your VM heap size for better stability and performance.

Note: Root Booster is designed to work with rooted devices

  1. John Ormsby-avatar

    Doesnt do anything. Period. I tried switching it from SPEED to BATTERY (and vice versa) and there's absolutely no difference in my used memory or remaining battery life. In fact when I set it to SPEED more of my memory is being used (from 70ish% to more than 80%), and everything lags a lot more so whats the point? Would rate 0 stars, literally does nothing except slow down my phone and take up extra space.

  2. Antony Stinil-avatar

    apk Fantastic.. I use this app for battery mode. And I never imagined any root apps can save this much battery by tweaking the phone Governor. As my phone is already capable and has enough speed, couldn't feel much difference in speed mode. But if you face battery drain issues after root then this app is a must try. Don't want to buy the Battery+ paid version without trying it. Hope in future there is an trial period for paid version.

  3. Laaiti Ekenstéen-avatar

    Laaiti Ekenstéen


    premium apk This is one of the best apps for root, and one of the first things I install after rooting my device. It can extend battery life and improve performance well for free, but I personally recommend paying for the other boosts. It can improve your performance and battery life on an extreme level, and it has a stability boost if you need your device to be stable. All of this is extremely safe and hasn't affected my phone (Motorola Moto G5S Plus) in a negative way, and the developer is trustworthy.

    pro The app is absolutely a legendary one! I'm using Performance mode and I don't regret on that! Legendary app! Keep it up! For those using Vestel Venus V5, use Magisk to root your device. If you use another methods, they won't work and crash all apps requesting root — Even this one!

  5. ryan bancifra-avatar

    combo Thank you devs for this most wonderful most effective most usable and most efficient booster app that i have ever seen.. i just downloaded it and then i choose the speed mode and then bwalahh.. my phone is super fast.. keep up the good work and please create more efficient apps in the playstore.. congratz..

  6. Liberty Action-avatar

    cracked apk This app is terrible. It has a horrific display and does not allow user to see the entire screen. It goes into this weird mode and I have attempted to rotate the phone and even force rotate thinking that it funtioned better and was meant for prtrait mode...This is NOT the case It just became even worse in a portrait mode. App is TOTALLY USELESS . Dont download. Should be removed and redesigned. I do not know if it functions as it claims it can due to failing basic function of them all: display

  7. David Beckwith-avatar

    xtreme mod apk I have a POS Dragon x10 and it actually works for the first since I bought it. Wow everything use to make lag so bad I felt like I was ripped off but since this root booster it truly performs for the first time. Thanks man

  8. Elviss ccreer-avatar

    shampoo Great app root. Booster. Much better if this booster can notify if the finished of an Apps cleaning.because like what I do now is clean it manually by tapping the button..if can add to Automatic much more better..

  9. Hector Brown-avatar

    premium Fantastic app, especially impressed with how purchases are handled... basic functionality ad-free without them, and an advanced tier of modes for money that you can even just buy individually

  10. Durga Reignß-avatar

    for hair This app is so great. But when I used speed boost on my device my device battery is draining fast as 1 min - 2% and when I used battery boost my phone was more slower than tortoise when I used to play games... please fix my issue

  11. Kimberly Rogers-avatar

    Kimberly Rogers


    Yes i do notice a difference in performance. It def is running much smoother and my apps are opening much quicker. The lag that has been a real problem on my phone has all but been eliminated. Thank You, Thank You! 😊

  12. Jamie Dee-avatar

    Wow.. I had a nexbox with an s905x CPU in, which I also have another box but unfortunately the CPU was running 1502mhz , compared to another identical box running 2000mhz.. the 1502mhz was noticbly slow.. installed this.. as the box is rooted.. Jesus Christ! Exactly the same as the faster box! Yes! Thank you! 🙂

  13. anthony ejegi-avatar

    I think I am enjoying the app. It keeps the cpu and battery working real fine. I was already having issues with my old and dwindling battery performance but there seems to be a boost

  14. Ronald Ouellette-avatar

    Ronald Ouellette


    Seems to make a noticeable difference on an older device (ICS) when set to speed option without creating instabilities. 4 instead of 5 stars only because there is just so much you can accomplish with old hardware- not a reflection of the program itself. Once set to speed, the device retains the settings between boots with no further action. Probably rates 5 stars as an app.

  15. ilxGHxli-avatar

    Does what it says on the tin! I'm not sure how non rooted devices would benefit, I'm rooted. But it works great, really enjoying the extreme stability mode! The descriptions under each mode are simple and understanding is simple. I'm used to modifying kernels and such but this device hinders my ability for custom kernels and this app does the job! Still people, use it sensibly!

  16. Adesh Dahal-avatar

    This is a very good working app after the installation of this app my phone work very smoothly and very fast.this app also help me to save the battery of my phone for long period of a time .I LIKE THIS APP VERY MUCH...

  17. Jason Hodge-avatar

    It does as advertised, but the best feature you must pay for. "Stability" costs money. Thanks to the developer for creating a great app

  18. sola lee-avatar

    Using the free version: Well done, well design and developed. It does not close running tasks like most task manager. It rewrite your starting script to optimize your phone. Everytime you rewrite the script, you will need to restart the phone. But it does the job well.

  19. Philip Levine-avatar

    Just recently installed, and this root app seems easy to use, and does a reliable job tuning my NOOK HD plus android tablet.

  20. Michael Wilson-avatar

    Ive had this app years! And never gave my feed back !this application everyone needs!, when your smart phone is slow! Get this app! It cleans out storage wasted! And cleans your phone at the same time! Ive had it for years! Maybe 5 years now!. Thank you to all and Happy new year 2020! Mr. Wilson.

  21. Sanket Kolhe-avatar

    Increases performance considerably......but it also increases game loading time..... performance is perfect but too much lags and freezing during fight with enemies in pubg.......most imp it makes system very much unstable

  22. GTB7979-avatar

    Wow, it works! Works very well actually. For the life of me I couldn't and still don't know why my rooted S7 CPU was normaly at 90% usage. Whatever was causing it this app took care of it. It's super fast now! I did buy pro, gladly

  23. Tokkos-avatar

    I love this app please make the extreme boost free,some of us wish we can afford it. Thankyou for a great app. Stefan Claassens.

  31. A Google user-avatar

    I have a 4 gigs of RAM of memory with a 32 gig internal Hard drive on a LG G6 that I'm testing this on. It seems to be working no differently than the unpaid version in my opinion. SD Maid & SD Maid Pro in the play store do about the same thing however I paid more for this than their premium version. Plus their app gives you more insight to what is really in your device. I was kinda hoping the same thing here but was disappointed. If you're going to charge to clean emulated data then you need to make sure when it does clean emulated data it doesn't clean your installed Games, bc no one likes re-downloading game data every time. This will increase your data usage, data amount, and wasteful time spent waiting uploading it again. Over all, out of 5 for this app I give it a 2.5 for the basis boring in-app design. I'll give it a 3 for an overall, overpaid, premium device booster as I really don't see a difference in it being better or not.

    For the battery I'm still unsure, that is debatable. Using the free version. This app did however speed the phone up to a very noticeable difference. Since I've cleared my cache out before by using the power button and volume key it seems to have done this within the app. Will be monitoring my battery drainage since it's a new battery as well on the phone but it certainly speed the phone up and Google is way much faster. Still thinking it cleared the cache in which no app is needed for that.

  33. Baby Kooran-avatar

    Very wonderful application. It works on phone as designed by the developer.please accecpt a bundle of thanks.

  34. J.-avatar

    Can really tell a difference! Phone is getting stronger signals now and running faster!

  35. Jelle Smit-avatar

    Phone was laggy and freezing a lot because of other booster apps. This one actually does the job the way it is supposed to do it. Perfect stability and speed.

  36. Paul Cairney-avatar

    Looks good , very simple , only performance isn't showing off yet

  37. Janine-avatar

    My battery has been reading 100% battery with about a 30% charge throughout several roms. With your app it was a one button fix. It powered off showing 77% and came back on showing 11%. THANK YOU.

  38. Sebastion Dahl-avatar

    It really does work fast. its like the first time I watched how to make my phone faster for beginners and you click what ever 5 times and open developer options and turn off animation blah blah. Yea that fast (;

  39. lemon bun-avatar

    Got paid apk for free,tried it and I'm satisfied. I'll buy the app when I have the money and I definitely recommend anyone using this to unlock full feature.

    Love it! Excellent developer. My lenovo tb-x103f is rooted but I used it on the same device before I had it rooted and it was excellent then. Overall great. Would not have taken time out of my day playing halo 3 MCC and MLG wagers if it was not excellent rooted or not. Thank you Dominik. Bought the pro version recently and it has been well worth the small investment for the considerable improvement. 5* all the way. Hope this helps someone in then future in deciding. Thanks.

  51. Mary Aguirre-avatar

    It's the only app that I know that actually works better for me than the others it does what it says the only problem I get now is once every so often it shuts down and reboots my phone other than that no worries. I would like to send my gratitude and also to all of the developers and personal for the app thank you so much for your time and help wish you greatness . Sincerely yours Reynaldo Barron Jr

    actually, this worked immediatly in "speed" mode. without adding stuff like 3rd party app overclocking or other stuff, which have done on other equipment in past, i have tried everything from cleaning to adjusting background apps running, etc., only helps a little and not for long. This, on LG rebel 4 with Oreo android works well and same for 3 days running. soon as i turn the "speed" button on. I actually want to try the pay for the premium version and will after friday. surprised.

  53. Zackeroo HQ-avatar

    Got the extreme version and I'm pretty happy with. It still doesn't give enough high antutu benchmark scores like Lspeed does. It also needs a balanced mode because right now you can only choose between speed and battery. One more thing: When turning on each mode it takes really long and needs to be shortened or at least not show the process of it changing everything

  58. A bagazzi-avatar

    As an experienced Android user since gingerbread, and a senior member of xda developers, am somewhat suspious of this app that in accutalyity it does anything other than heat my phone up and drain my battery. On a rooted device I have seen much better results by flashing a stripped down custom ROM, also a CPU govenor app achevies better results by under clocking your Android devices when you are running your device for basic tasks like browsing etc! Which saves battery life, and then overclocking for faster results such as playing games!

  59. Never Leaving Harmony-avatar

    Never Leaving Harmony


    This app is A++. It's the best one I've downloaded. It works super fast and has simple controls. In about 30 sec it fixes every annoying issue that my phone gets on a regular basis. If my phone is sluggish, battery is draining too fast, Google Play won't load, or my 4G signal drops to 1G this app fixes it all every time. I'm not even sure if it's designed to fix everything that it fixes, but it does! I'm definitely buying the paid version even though I'm 100% satisfied with the free version.

    Great root booster. It's really Does for What it' says on description.. 5 Stars rates Dev..

  61. Iron Force-avatar

    I just read some reviews for entertainment. Dont install this or any other Battery, Ram or Cache Cleaner Booster on your flag ship devices. Especially non rooted ones.. Theres reviews by Note 8, Note 9 an LG with 4 gb of ram. You dont need it !! You already have the equivalence of 2020 Corvette engine stuffed in a little 1980 You already have a Task Killer and Cache cleaner built in that knows when to go. Your making your device's work harder. Only for old rooted low ram turtles.

  62. Daniel Pomales-avatar

    It's simple, straight forward, sometimes that's all you're looking for.

  67. Ant Guest-avatar

    I noticed my phone could not handle the emulated games I wanted to play so games force closed or had unplayable lag. Downloaded this free app and it managed to free up an extra 22% RAM and boosted my CPU. I actually thought it wouldnt work but I was so impressed I had to see what the paid version was capable of and it's a must for gamers with rooted android. It made my RAM usage fall from 78% to 22%! When i'm done I boost the battery so it's fully charged in 35 mins and it lasts just over 2 days!

  68. Kacia Keegin-avatar

    When I try to upload my favorite game, my tablet flags it and needs an updated version of android. I thought this would solve my problem, but its a superficial fix and doesn't help to update android....

    Not much to this. Said it might be a bit yet was done before could finish pouring a coffee on a 32GB HD!! Not sure yet if the $3.50 for what was done was a good thing or a flush. Was nothing to guide my choice except some graph at the top of the screen about the only marker to go by. If it had made an effort to test my system & then said that Option A, B, or C was necesarry would have helped out.

  70. Amy Pagnozzi-avatar

    If I'm wrong and overlooked a setting I will change my rating but free version doesn't explicitly state which of your battery draining appications are being hibernated... I understand only premium users can control the hibernation but seriously no shortcut to a log which shows what the free version did to my system? (I suppose I could use videocapture to transcribe the report that flashes on the screen but why no way to just read the darned report?) Rooted users wanna know what's under the hood!

  71. Dzul Juniaf-avatar

    felt the difference a bit. but i dunno. its only an hour after i installed. will monitor again

    I loved it so so much.Because my game (free fire) so laggy and used many apps to clear the lag such as Lspeed[ROOT] ,One click[ROOT] booster.....etc but it didn't work exactly.But not with this "ROOT BOOSTER" I am extremely happy it removed the lag and a i can now play the game smoothly.Other modes also is extremely good and I loved it...😊😊😊😁😁😁

  73. [RYAN] [D] [ROBERTSON]-avatar



    for most users, this will do nothing, cause your settings are already confugurerd as such. merely checks that your settings match what device number suggests. and if your settings dont, app will crash. so at most it attempts to clear SOME cache/reset some figures. ur device probably does this automatically anyway so i can see why the dev abandoned ship after the ad revenue started flowing. in summation, it steals ur device info , lies about its functions, remains collecting$ despite no support

    Great app, no adds, no nonsense. Simple and streamlined interface so it's effortless to understand and set. Basic, but essential settings that drastically help manage phone performance power and battery life expectancy flawlessly. A big thanks to Ropt Booster abd the developper for bringing an amazing app to Android.

  77. EpicWaffles449-avatar

    Nice preset overclocks, free version gets me a 2.457Ghz overclock on the 4 performance cores, and leaves the other 4 stock (Snapdragon 835). I checked AIDA64 after setting up the speed profile, works great with NO ROOT. Less power efficient when on (locked at 2.457Ghz instead of simply boosting to that when opening apps etc.) But thats obviously to be expected.

  78. Dave T.-avatar

    Speeds up my android device as well as making it more stable.

  79. A Google user-avatar

    Nice performance boost on my old rooted Samsung Tab A. It had been getting so sluggish that I almost replaced but decided to try a booster app. This was the only one that worked. With a 30% speed boost the performance is acceptable. Would like to see the app show you before and after performance metrics.

  80. Nazrul Hisham-avatar

    It's really working on my tab. Lately my tab always make me mad when it's becoming slower and slower eventhough I use another cleaner.When somebody recommend me to use this apps I tried and the result wowww,so amazing! My tab now can work as normal and more faster than before. Highly recommended!!

    I am using basic boost mode and system speed is noticeable.

    This app is effective and does what it says, but I wish it were a little more customizable, maybe even if it were just for the paid version. I want the CPU governor boost without extreme hibernation, but there are only 6 (or 3 with the free version) options I can choose from.

    Works like a charm. I suspect my phone goes about 30-40% faster with this app.

    I was about to throw my tablet at the wall in frustration until I got this app. It's like I have a new, better one! Remarkable for it's effectiveness. Am downliading it to ALL my devices. Thanks!

    This is the only app that has truly improved performance on my Samsung J700T playing Heroes and Villagers. Great program!

    On Android KitKat 4.4.2. Google Play Store downloads the free version. But I paid for the premium version. Any help from either the developer or Google would be appreciated. Spent hours troubleshooting and still no solution. First time purchasing an app from Google. And already have bad taste in my mouth.

    Excellent. Wonderfully effective, slightly surprising results for non-root users aswell.

    I'm not liking how for non-root users it is now "cleaning" instead of the boosting of the things it used to boost. It worked fine for root and non in the past why not now. Still 4 out of 5 cuz it works good just not the same.

    Great way to reroute internal phone circuits without any of the mess$ 💎🗻💎

    Really nice cute app very efficient and quite simple yet efficient

    My phone is very fast now when I started using this app. Thanks for the hard work you did building this app. 🌟 🌟😘😘😘

    I am impressed. only been a few days but so far so good. I bought a cheap phone from MetroPCS it barely functioned at all and after I put this in my cheap piece of junk Galaxy A10 improved in performance by at least two fold or more. I highly recommend

    Users be aware, check your 4G speed after optimization, I was struggling with a low speed data speed on LTE/4G, I was only getting 0.8-1.8 Mpbs on my Zenfone 4 Max, after hours of troubleshooting setting, replacing sim card and APN reset, I found out issue caused by RootBooster Speed Optimization on my Android 8.x. as soon as reversed to Stock Setting my internet 4G Speed jumped to 25+ Mbps from 1.8!, this issue seriously impacted my operations.

    Perfect, fast and reliable. Thanks for your satisfied..

    Love the app. I notice my batteries are better and my phones are faster with this app. I can't tell you exact percentages but I do notice a difference.

    Did two Antutu benchmarks, one stock, one with speed boost applied. Was encouraged by the result so paid for extreme speed boost. Yet another Antutu increase. Now a previously hopeless tablet is performing very nicely! Nice one devs, very impressed!!!

    This the best I've come across so far. I can see that difference with first boost. I have a Android KitKat. I always run out of storage and my phone lags. This was worth it. And yes, my phone is rooted.
