Twice as good as Battery Doctor This app has been great at extending my battery life. Was getting tired of BD telling me I needed to optimize about every 20 minutes and then giving me the same list of 36 apps that were draining power and claiming it shut them down. I figured it wasn't doing anything. So I switched and glad I did. More info: after update to lollipop now it is very glitchy, I have to restart my phone every morning after it's been sleeping because once an app is opened I can't close it. Still like it, just not as much

Michael Linkewich

Almost perfect Great design and simple to use. Would love a background auto optimize option to deal with auto restarting apps while device is locked.

Christopher Dawes

Love this... Best in category. Intuitive, effective, cool looking. Triple threat !

Nique W

The only battery app that works, but buggy as heck This is the only battery app I've tried that consistently gets my battery to stop draining wildly, but it wreaks havoc with my lock screen and app switching. It automatically bypasses my lock screen and password, making my phone unsecured, and half the time when I try to switch apps it goes to a black screen. I have to lock and unlock the phone several times before it will let me switch apps or go to my home screen at all when this happens.

Naomi Cole

Nice app, great shortcut in the menu bar If this had a "begin on phone startup" feature it would be 5* Update- this messes with my automatic screen lock and overrides the pattern unlock. Sadly I have to delete it :( The shortcut menu is really great and I will really miss it

Kaizad Banaji

Does NOT WORK AT ALL ON One Plus Onr.Despite Giving So Much Feedback No Improvement And Also While Using Mobile Data Or Wifi.Would Be Appreciated.This Is THE NEED OF THE HOUR.

Tanaya Wright

Cool app Cool app. It's definitely a keeper.

Yerima Mohammed

Good app. My battery management consultant

Sharon Miller

I'm giving because I don't understand it so it could be good or bad but I have to find one I can understand . God bless you

Junnyl Ferrer

Good, But when I open an app the power saver unfortunately desappeared. Please fix it, thank you and maybe next time I could give you a 5 star.

Naveen S

Love it! Works pretty good almost for all phones but needs some bugs to be cleared. All the best, job well done.

Fernando Olvera

Battery saver Rxeapplication this is the best ofall match to this app.

Excellent! Several alternatives are themselves battery hogs. Not so with this.

hub abresch

Reliable and stable Does what it is supposed to do without gobling up to much resources.

Karthikeyan Selvakumar

Josh Sel

Beautiful ui I like the visual appeal. Will see how it works.

Muhammed Mubbashar Ali

nicole webster

It's too dark... Too confusing This is ridiculous that there's so many darn apps.. It's unreal..! I can't find the old one I used.. & liked 4 along time.. But Verizon said I shud get rid of those, their bad 4 the device .

Deb Taylor

Seems to be working I try apps looking for 1 that works better than others. Some have same or similar claims re what they'll do. ALWAYS confusing to me. This one am still testing but so far SEEMS promising as 1 may be able to keep & eliminate the others..?

Chrys RD

♡ it now Have tried before w competitors to compare&contrast and honestly couldn't find much that really , well, stood out in contrast... till now. Present gen is uber nifty&significantly superior to alternatives I've reviewed. Oh one thing I'd love to see is an automated run in bg

Kosova News

i'm using my phone at 1% battery About 20Mins this app is Perfect. ?

Julie Hennessey

Awesome app!! Just what I needed, this one is a keeper for sure ? thank you battery guys!!

John Boros

Battery Life Improvement from the initial install. Haven't had the app long enough to totally vet. Everytime I use, prompted to rate.

Anam Arsalan

Just perfect Can't believe how can an app holds the battery this perfectly 10 stars from my side greatest app

hardluck 1995

1 star because it keeps begging for a rating. Only installed one day ago. No change so far. Would rather rate in a week but it's strong arming me.

lonnie henry

It seems ok but --- It seems that I am always having to optimise the thing about a hundred times a day, and it gets sickening, also it may be my fault that this is happening, I'm not really sure

Osman Goodys

Super duper This the the app that kills the running apps completely, I ve tried several others of battery saver but this is the best. One thing is it slows down my system a little bit but all the same it's good

Greg Bentkowski

Mute volume No matter what mode I turn on, BSl wants to mute the speaker. If I turn vibrate on its still in mute. Makes no sense.

Patrick Corrigan

Great Went from an 8 hour battery life, to a 2+ days battery life


Absolutely fabulous Before I had this app I would be lucky to get 7 hours but now my battery lasts 1day and 1/2 .also I have upgraded to Lollipop 5.0.1. Which has a bad reputation for battery.i have the Samsung galaxy note edge and couldn't be happier.told all my friends about this app. Thank you again for producing such a marvellous app knocks battery doctor for six and a lot of others I have tried.

adrianto ponco prabowo

Just seem and catch It More lighter and see that the application are catchy..

Johnny Wong Kiing Yi

Suitable for Galaxy S3 Good & functioning but unlock screen setting not good need to be modified

Phil Sanders

I like it ? The best I've tried, as of yet.

Chivonne Ruggiero

Love it Glad it doesn't optimize every 20, minutes like others. Instead you can put them into hibernation..

kishan shahapur

SONY EPERIA 4G The app is amazing i like. It saves my battery by optimizing background application's. But I want remaining time to be show in the notification bar please fix this bug i will give five stars

sailesh kumar

Its pretty much useful app for the battery minded people

CMLL Luchador

Good now Satisfied more than ever. Now i can stop all apps that are draining battery. 5 stars for this masterpiece.

Parris Williams

Greaaaaat! Put a blue or green % notification in the status bar and it will be perfection.

Charlie Plum

Its better than most Yeah you get ads but that is what we live with now does what it says which helps keep phone usage down

Darren Gust

Testing it It seems better then Security 360 that used 25-35% overnight, this one uses a lot less. I like that it shows you the apps running and option to close each or all app services. I like it so far.

Anthony Jamerson

I like the new look but the upgrade lost 7 to 9 hours of time used to get 25 to 30 hours a charge no just 21 to 22 hours still a must have but would like the other hours back

Vladamir Rasputin

Battery Saver Good app does it's job.


Good So far is good.. but in toolbar status is always Estimated Left not Charge Rwmaining if Charge in use.. Please fix it

Zahid Malik zedi

It is very bad app of all

Лена Михайлова

Useless This app did nothing but lie.

edwina fawke

Good but couple of issues I like this one! However, the ads are very annoying & it is a bit intrusive

Pernille Juhl Kristensen

good but I hate ads only bad thing is the ads. would like to get rid of them.

Veronica Miron

Very good as saving battery, but l agree with all- the adds are very annoying

Greg Holscher

Seems to work Just installed. Will give it a couple weeks to see if any improvement. It did let me know of apps running in background draining battery that should not have been.

Debra Morrison

Battery Saver- Power Doctor Love this version of "battery saver" cause it helped show Me all apps "running" in background & using too much of My battery! So I had a choice to "uninstall" apps I opened & hadn't used yet....get a little "App Install 'OCD Happy' "! This is My 3rd new cellphone....told Husband for My Birthday in March....should just "buy" Me the newest IPhone! "Thank U!" "Aloha"!

Jhon Black

adds adds adds too many adds over there...otherwise nice app but need more auto night mood..

Wilsie So

Nice! It is nice. But, after i charge my phone my screen lock doesnt appear anymore. Can you please fix this issue. Thanks!

Mohamed Yaeesh

Apps good Apps good but ads annoying

Ginni Sharma

Its very good battery saver bt many times my screen dosent appear all black thats why i m giving 3 stars fix this issue and i will give u 5 stars

John Velez

It helps out very well. However, the ad videos that take around 30 seconds to play are annoying. I can't even skip it since it won't let me. Other than that, it seems okay so far.

Geraldine Wilson

Battery saver This is very helpful to save on battery time thew the day.

Hams Princess

Its taking much of my phones memory please make an option to move it to sd card please . I am using it for a long long time but my phone is getting slow . Please make an option to move it to sd card please

Dorothy Gottfried

Battery Saver I like the fact that I can optimize my usage. I can see my battery life all the time.

Suleiman Adeyemi

Optimism. I do trust this Apple will perform well above expectations!

Jay VanHorn

Start up? It did seem to save my battery but I had to open it and start t up every time I powered on my phone. If it started automatically then I would have given it a higher rating

Rahul Roy 9904148001

Best Battery Saver World's No.1 Best battery saver. It's five star app. I very like this app. Very nice app. Please download and enjoy.

Dave Bacolot

Nice one but it is much bigger size to fit on my storage..

Frieda Huysmans

natsu slayer

Please answer my question thank. Why won't close the apps running? at first i press the optimize then it close but after few min it come back again...very weird.

Amar Faruk

Useful Very good app. But there has a probable that is, it's percentage not accurate.

Mark Heading

Phone is cooler! Phone is cooler and lasts for 2 days, no charging....Amazing!!!!

Diego Martinez

Like it but want to change the style of the style of the indicator in the status bar to the circular I saw DU Battery Saver had. (The way it look in when status bar isn't pulled down).

Really saving battery! I like thus Battery Saver because it does all its work, boost my charge, and optimize many apps! Like it!

Unesh Kumar

i luv this app but update lite and very fast change with life saving battery. update new looks notification battery indicate in digital looks

Eric Martin

So far so good So far I like it there is only one problem however and that is the widget is basically a quick setting widget which I don't need and it does show your battery percentage the only other thing would be it gives you an additional lock screen the thing I do like about that though is it does show your battery percentage looks like a pretty good app and I will probably spring for the pro version Samsung Galaxy S6

Ernie Kersey

Can't do what it says it does. It tell me battery is draining and wants me to shut down apps to stop them from draining battery and when I do so I expect the app to do just that but no it doesn't but asks me again 5 min later again and again.

shubhadip ganguly

It is very good for battery.

J.R. Orci

Best of the bunch. I tried so many battery manager apps, and all of them had ads all over the place. I especially appreciate that you don't plaster ads on the charging screen. The app design itself is nice and fluid. Features work well. Will purchase the premium version.

Carey Brown

Battery saviour This app works better than advertized; I get days of battery life routinely.

Timothy McDonough

Smooth app Smooth running out there are a few glitches here and there that's why I only gave it four stars but other than that it works perfect

Mariana Ivonne Falcon Gutierrez

It doesn't work at my phone

chris fitch

No issues Takes a few seconds to use it and it does buy more time for the battery

Marla Walls

Great App Battery saver!! Thanks Google!! *****

Chris Ellard

It's okay I guess All the battery savers I've ever used are pretty much the same as this. Doesn't really seem to do much except shut down apps which I can do without it anyway. Does it quickly though so 3 stars for making it easier for me to do.

John Smith

Worrka Seems to work. Tried other apps to increase the battery life of my phone which studs does seem to work along with this phone so I have 70% or around 70% instead of 20% on my Samsung Galaxy S6

Adeolu Oluade

Ignis Battery Saver This is a great app that has replaced my use of Greenify.

Farshad K.

A bad App - A memory / battery killer ! This App drains battery like crazy itself. The memory goes too low causing many issues promptly!

Battery Saver I like this app cause I'm always busy and sometimes forgets to charge phone and it allows me the extra time I need

Miss M

Didn't notice a difference Had this battery saver on my phone for a few weeks. I wish I could say it did wonders but it didn't. Also the % for my battery was always wrong. Right now my phone battery reads 51% but the battery saver says 75%.

Deepesh Shrivastava
