    Whatever you do, do NOT download this app! 1. There is WAY too many ads 2. Although it claims to cear cache and clean your phone, it doesnt do that at ALL. I try and clear cache and cool down my phone , but nothing changes. No difference, no extra space, nothing at all. 3. And finally, I've seen enough to know that all this app does is drain your battery. Dont download it, just don't.

    When I first used this app, my phone use to last at least 3 to 4 days max. However overtime with newer updates, that started changing & my phone's battery not only lasted less days everytime but my phone started to slow down, making it impossible to use, even with restarting my phone. My phone's battery only lasted a day or less & I've done everything with the app, but it still didn't solve any of my issues. Today I've completely uninstalled, it since it doesn't do the job like it did when I first started using it. You better off downloading a different app. Don't waste your time downloading this, its not worth it.

    This app is very helpful. Only four stars because it doesn't seem possible to edit modes. I want to delete two of the modes that came with the app and one that I created but no longer use. I can only figure out how to add more modes. So, to clean up the modes, I believe I have to uninstall the app and start over (and that will only let me get rid of the uneanted mode I created).

    I installed this to test it's capabilities to fix the battery draining issue for z5 on a nougat. Surprisingly, the battery draining issue was resolved when the phone is idling. As compared to without this app, the phone would lose 1% battery every few mins. The only thing I hope for this app is to have a pro version to disable advertisements. Other than that, it's definitely a worthwhile app to install especially with phone with battery draining issue.

  5. Richard CMG-avatar

    Overall this app does what it says, my battery certainly lasted longer on this app then some others... BUT, It made my phone less responsive and jittery. And the onslaught of Ads produced by this app was a bit ridiculous! It's nice that some of the advanced features could be unlocked by clicking on ads and installing different apps, but at the end of the day it just sours the whole experience to be constantly adwared! Going back to Greenify or Avast battery which do a good job of extending battery life without reducing performance or being ad machines.....

    This app is very useful, however it has some drawbacks which is why I only rate it 4 stars. I would have given it 5 stars if you didn't often say my phone is too hot when it says elsewhere in the same app that it's not and if I had confidence that when I did a memory cleanup it really was clearing the things it said it was.

  7. Eir-Roumar Lowell Degamo-avatar

    Very helpful if you want to prolong or increase the battery life of your phone. The app does this by killing background apps and games you are not using. Moreover, I also love the additional trash cleaner feature of the app. However, there are too many unnecessary notifications especially on the trash cleaner. These notifications are also very INACCURATE (e.g. notification says you have 1.5 GB of trash but while scanning for trashes, it's only 500 MB).

  8. Bluesoul-avatar



    Okay first off I like the app it works great and all, but the thing is that when I gave it the access ability stuff it said it would keep track and watch everything I typed, which made me really insecure and when I run my other battery saver that shuts of apps that drains power, it shut off this app, which doesn't give me good vibes considering this is a battery saveing app but other than that it does save my battery, but I am uninstalling because of how insecure it makes me feel

    Helped to cool my CPU while charging effectively increasing my battery life and charging abilities. The app did as promised and that's all I can ask for a free app. There are ads but they are not pop up style ads and they are not that disruptive. I understand the developer needs to get paid and rightfully so rather than charging the end-users for their app they run off advertising revenue and I don't mind.

  10. Lonnie Hetschel-avatar

    Garbage which does nothing. It kept telling me it was saving me battery time, but battery drained faster than ever. Every time it did an optimization it would pull up a screen of suggestions to improve performance, but it was just a list of ads and suggestions for other apps. The app also automatically open my FB app with a suggested posting to recommend the app to my friends. Stay away from this app!

  11. A Google user-avatar

    A Google user


    Maybe it optimizes my battery, maybe it doesn't... but what it canNOT do is start playing video ads when I plug it in!!!! What the hell?? I plug it in and I start hearing two gnus (the animals) discussing... auto insurance?? I am not even sure. I was livid. I've had this app on my phone for many months, but man, it is gone now. An app that on its own starts playing an audio advertisement when I plug my phone in is INTRUSIVE in the EXTREME. Maybe the developrs will fix this, maybe they won't. I guess we will see. Unbelievable.

    Used to be simple and straight forward with no adds. You could upgrade at a small cost for extra features to save more battery. Now it's overloaded with adds and wants you to install a buttload of extra bloatware, I went back to Norton Clean after realizing how botched this new version of DU is. I would have loved to write a positive review, used to be great...

  13. Antonis Thrasivoulou-avatar

    Antonis Thrasivoulou


    It made things lot easier and i don't have to worry running out of battery too quick at all. Why 4 stars? because when my phone charges and i try to open it, it starts shifting between the lock screen and the "fast charging" screen non stop. Every time i have to unplug it first and than open my phone to prevent it, but its too annoying to deal with. One more thing, the app crashes every time when i restart my phone and goes crazy with messages about it, it was unstable.

  14. William Hoverman-avatar

    William Hoverman


    Quite obnoxious. great for people who love random alerts going off for no reason at all hours of the night. Maybe they could squeeze in a few more ads as well, 500 just doesn't seem like enough. If you are easily distracted by shiny objects, this is definitely the app for you! Uninstalling now.

  15. Rayon Decor-avatar

    This app has started misbehaving. It gets stucked at "FULL CHARGE ONGOING" for hours. I had uninstall and reinstall, thinking it would be back to normal, yet it's still the same. It was not like this before, this only started three days ago. If there's anything U guys can do about it, maybe it's a bug or something, please do. If not I'll uninstall it completely, because it's basically not useful now, it's been stuck on full charge ongoing for more than 3 hours now I have been charging my phone

  16. Asriel dreemurr-avatar

    it's bad for some types of phones and one word ads, i have heard rumours about this app! it said this does not actually save battery! it is true! and the "game" thing bothers me yes it does clean junk files, but that is the only use! (besides giving "game" on the starting of your phone and also "deactivating background operating apps" yes. but saves battery? idk rumours says otherwise and i trust google, change my mind worthy to download but need a bit of an update (i need to see proof the rumours are fake)

  17. John Smith-avatar

    John Smith


    I like the app, but a few MAJOR things they need to fix 1 - No explanation/way to rename/remove the battery modes you can make. You can make more, name them anything, but NO WAY to edit/remove ones you already made. 2 - I’ve been getting a ''Low storage reminder (phone storage less then 30%'“) POP-UP Multiple times a day and it’s coming from this app. Just click the ‘clean’ button on this popup and the DU battery saver starts and starts to do it’s thing. I ALREADY have a separate app that keeps track of this info and I don't plan to delete anything to make more room since I'm happy with what I have on it. NO way to disable this popup, disabling notifications for the app itself does nothing. 3 - The Optimization/cleaning, is only a placebo effect, it doesn’t tell me what Its doing when it’s ’optimizing’ or any other thing it’s doing. It just shows a spinning icon and saying it’s ‘doing it’s thing’ NOT helpful at all. I want to know what’s happening, why it’s doing this and what can I do. PLEASE fix these issues soon.

    This HAD been my absolute favorite app EVER! However, for the last month or two, I've been getting many msgs, stating that this app, is actually a VIRUS! 😲 Even my provider warned me to delete it ASAP! It kills me to do so, as I'm unable to find a battery app that even comes close to this one's abilities. I've writen u a few times to inquire about this, but have never received a reply. Therefore, sadly I must now move on and delete. I'm unable to continually get my phone fixed re:virus. Bye.

    I used it a lot on my samsung s5, but I barely ever click on it on my s8. I feel like it helped the older phone but not the new ones. It also constantly auto starts itself and runs in the background and I get notifications that the app is draining the battery. It's alright, but Samsungs come with their own optimizing tool now so I feel its obsolete.

    Use to be a very good app but it seems like anymore it doesnt want to work half the time. Its mostly the phone cooler and smart. The phone cooler will say its heated but when u do it it says no apps and the smart clears 2 or 3 apps out of 14. Please fix this. Ik its not my phone because i have tried it on 3 other phones so its the app

    I was using the old DU battery saver pro, which worked well until it mysteriously stopped working. I installed this and it works very well but the notifications are bothersome. However the main reason I didn't give it 5 stars is way too many ads. I am willing to pay for an ad free version, so why not offer it?

  22. A Google user-avatar

    A Google user


    This has definitely improved my devices battery life. Function is great. The interface could be cleaner and more intuitive. The amount of ads is alright. Like most free battery saver apps it does try to get you to install other apps by the developer but not in an intrusive manner.

  23. Angelus Tenebris-avatar

    Angelus Tenebris


    This latest version is a pure waist of time! First, the "DU Battery Saver" constantly request that "YOU" action a request it displays for cleaning your phone or tablet. It does the same for other requirements. In my opinion, the saver should be automatically performing any tasks without you constantly opening the app. Furthermore, after you complete the task it requests you to do, an advertisement shows up!... "WAY TOO ANNOYING!"...

  24. Debangshu Mukherjee-avatar

    One feature should be added in this battery saver and that was RAM usage control. Whenever RAM usage was too high then this battery saver will control excess RAM usage and can close the apps that are using too much RAM. RAM usage should be controlled in every minute. Specified limit should be set so that RAM usage does not go beyond the specified limit. This battery saver will automatically control excess usage of RAM.

    Please fix your app, i have a problem when i open a game and it has a downloaded game script or something in my phone to run the game, I come to this glitch and bugs, i find out that du battery saver is erasing some of the game file/script to run the game. Please dont make your app erased some of needed files. I rated this 1 star because its so annoying i have to download again the game and the game file and its suck and your app also.

    It's a great app. People like me love to check the graph of my power usage from time to time, and previously, it did a great job there. This updated version, however, deletes your graph when you restart your phone. I'll like you to correct that. Have my regards.

    I have been using this app for months now. It seems like it works, but I can't be sure. There is no noticable battery saving benefit. It keeps cleaning the same junk files over and over with no difference. I only keep using this app because I like the placebo effect it gives me. Thats all.

    This app is a God Send. Without it, my phone would literally die after being off the charger for no more than 45 minutes(even when it was brand new). But with this app, I was able to have my phone at least all day (7am-9pm+) without needing to worry about it dying

    almost great meekfully, but good enough for on system especially at speeding nicer efficiency efficaciousness like screening for (processwise) viruses; plus faster debuggingss upon key entry button presses. it said for first time no trash after one new set screen, (no real bugs found). Progress it y'all, such further reviewers' questionaire-type-blank for comments.

    App has potential but developers constantly advertise other apps. you can't access any of the features without some irritating thing popping up afterwards asking you to look at something else.. its too much. App tries to do too much.. why do i need a clean sweep offering.. Just want a simple battery status app....uninstalled.

    It actually works alot better then the battery saver on my phone. Its getting a 4⭐ review because when it cleans all of the junk and frees up space I cant use the saved memory to download any more apps. I also dont see how my phone gets 42 hour battery life on a full charge but it does extend it further then what I usually have. All and all it is a great app :)

    People these apps dont work the only thing they do is close all apps that are running that is it i would consider this adware because with apps like this they pop adds everytime when you use thier apps or open your own apps. if you really want a fast charge use the cord and cable that came with your device its why it csme with it my phone charges with the original cable takes an hour thirty without it takes 5 just use the original cable.

    Once I installed this app it changes my phone, very badly, my phone gets heat every time like super hot once I click cool down, my phone is still hot and I watch on YouTube some videos and in 7min, -6% my battery Cost and once I use my own battery saver (not DU Battery), in 11min only 2% cost on my battery and it is not that hot so I delete your app oh yeah I am using SamsungGalaxy6!

    It's a good battery saver just that the times sometimes fail. For example I optimized it and it said that I have 32 hours of stand by time an hour later I check and it said that I have 26 hours left. But in general it's a good app that closes all those unnecessary background apps.

    Not sure but this app si just a app this app doesnt affect battery life and saving it ita just making your phone worst cause this app uses background the more you run this app the more it is running in the background so 24/7 running this will reduce 25% of your battery i recommend you use your phone and charge it correctly and check your battery if it is not working correctly or buy a new battery Peace out...

    i like the app i wish it would come up in a section where you can run it whenever you want to not just when it pops up and tells you. like it runs on its own every hour automatically for optimization of ur phone. But you still get the choice of when to run it.

  41. KENTzee DA KING-avatar



    This app came up as harmful on Google Play Services just recently even though i used it for years. Only thing i can think is that u guys have injected something into the code in an update that should not have been added. removed the app due this... R.I.P Du Battery Saver... good bye

    Keeps bugging me to clean up my storage. Every day I watch it "clean" my storage just to have it ask me the next day. No option to turn off that feature. Also very intrusive. App should run in the background until you open it. Not show pop ups all the time.

    seems to work... but the first time i used it, I was able to extend battery life by like 70 % but havent seem to be able too get that out of the battery since. other than that i love the app. ya'll should speculate on an antivirus for the package...

    It was great at saving battery, it was good at doing its work. But then when I tried the auto brightness and closed the app, my battery kept draining. When I tried to turn this off, I could not see the off button any longer. Please fix or do something.

    The app works somewhat good, HOWEVER, several features are locked. To unlock them, there is an ad where you have to download another app to unlock that feature. But, if you do the download for the advertised app, the feature NEVER unlocks. I tried many times, and it never works.

    DU BATTERY is very useful! It keeps my usage time longer while keeping the CPU cooler. It shuts down apps that I'm not using or don't need. It has given me that extra few minutes, when I was in an emergency situation!

    I like this app but pop-up notification keeps popping up and I missed my alarm in the morning almost everyday. I set up a no disturb and turn off all notifications from the app and it doesn't seem to work. PLEASE fix it, your app might ruined some life who on their phone to wake them up.

    WAS one of the top 2 Battery Savers. Great graphics but too much silly animation wastes time and lots of RAM to clean and boost! Too many annoying notifications. *Warning* This app heats up your cell a lot=bad! Lastly they broke away Auto features to make you install multiple apps..Good bye!

    Works like a charm! doesn't take up much space at all. And it actually somehow resolved my battery problems. I changed settings within the developer options also but it didn't seem to work so I downloaded this problem solved.

    This is a really good app and it helps my phone to charge a lot I Recommend this app to people who has a hard time charging there phone and because it uses healthy charging really good app worth the storage and don't think twice before installing this app.

    This app said it would save your battery and charge faster right. Well instead of charging faster and saving the battery that app decreased my phone battery and It didn't even help with saving the battery. So in conclusion, I don't recommend this app

  53. AlantisBlue-avatar



    I dont know why but everything was okay when i started using this 1-2 years ago and now today suddenly it says that the app has a damaging feature and when i use it ,it heats up my phone . As im currently using a note 5 and this a new phone i just got .so i hope this is just a error that would be fixed

    Despite having so many ads, I liked using this app since it helped save a lot of energy being drained by demanding apps. However, Google Play automatically disabled it and said this app could harm my device.

    This app is great when it is NOT EXIST in your phone. Contrary to its description, this thing sucks your battery dry faster than without it. Great app, if there's minus stars, I would love to give it minus 5 stars.

    Quick and easy to use. Seems to help. Wish there was a one touch short cut tab to do the optimization/cooler/and trash cleaner all at once. Otherwise, it seems like a good app.

    Aah, can anybody tell me that is my phone mad, google play store or this app? I don't understand, it is written 13 MB but when I tap on install, it says that, "Downloading a large app of 1.5 GB. Download over celluar data?" So somebody, someone, help me! ON MY TABLET PC; Wow, Previosly, my tab needed charge ever 2.24 weeks, and now, after installing this app, it extended to 1 month {(if I do not use any wi-fi or data connection and do not play Need For Speed Most Wanted)the nfsmw used to drain...

    None, could match du battery, since its first launch. Others, are trying, but, no where near. Still, the champion, and, will stay leading, forever. Tried, the rest, but, only leading to confusion.

    It was a decent battery saver and while it had some flaws such as not being optimized for tablets,not having multiple tabs for its privacy browser,I otherwise,liked it....... I may not uninstall this forever at this tablet.......

    Been using this app and the cleaner one since my first droid phone. I would swear by these apps. My battery life is exceptional thanks to this app. My household are Pokemon GO players, this app keeps my battery life going longer than their iPhones... By about 30%.

    I have updated the app. App showing me same amount of cache of all system apps (chrome,youtube etc) then i click on to clean.I have search the junk immediately it is showing me again the same amount of junk. This app become useless. Junk does not cleaning. Boosting battery n cleaning ram is increasing battery backup.

  68. Peanut-avatar



    When ever I get onto my phone an add comes up, I press them all the time and i can't go second without this app yelling at me to do this and that. What i hate most is the app eats up my battery i've told the app to shut up so many times STOP WITH THE NOTIFICATIONS!!!!!!

    I just deleted my positive review after my app was mysteriously deleted from my device. It was uninstalled because it will cause damage. I have had this app on my phone for three years with no problems. Oh well, I can do without. If it causes damage I might as well delete it from my tablet. Anybody else have the same problem?

    The hours of charging and battery percentage are not accurate at all. It takes more time to charge and less time for my phone to die.

    I have not tested it yet, not sure if it works but the top review is kinda saying it is a virus via saying it enabled a lock screen and game. If it ends up being a virus i will un install this app and report you any way i know how. Making that clear.
