Battery lasts way longer. But was very disappointed that when my phone updated to android 5 lollipop, the most crucial feature was disallowed by the os!

Caroline Brown

Awesome app This app extended my HTC EVO 4G battery life from about 14 hours in sleep mode to 30 hours. My Samsung Galaxy Tab 3 now lasts almost a full week in sleep mode.

Mintarja Ang

Doesn't work on lollipop Please update it... current version cannot turn off data during screen off... i'm using lollipop os

Puttikorn Korn

Bed news this app can't disable mobile data when upgraded to lollipop ? App team i request to refund ??

Mayo Olubori

2 days in I've used this app for 2 days now and I'm thoroughly impressed...I never rate apps but had to do it for battery 2....usually my phone is down to 30% by midday...with battery 2 I'm at 75% and it's 12.35...can't even make this ish up...good job guys

Rez Rahman

Cant uninsall I dont need or use this app. When I try to uninsall it it doesn't go away. When I click on deactivate button on play store it gives message tgst it must be "deactivated before uninstall" yet it doesn't deactivate. Very frustrating

David Lekwa

Sam Tempesta

Rr.Annisa Witasari

The best Loved it!

Daryl Gervacio

Works Data and WiFi are whatr eally kill your battery. This cuts off data and reconnects every 15 mins to get notifications and stuff. Turn.your screen on, data is on. Screen off, data off!

Chris Simino

How to uninstall? This app keeps shutting my screen down in the middle of my games. Tried to delete it but it says it needs to be "Deactivated" before an Uninstall is done. The app is nice and ill give it a 5 star just dont want to use it anymore so until im able to delete you get this...

Eric Tee

Only Rooted? Then i have to give 1 star for this apps.. thanks for helping me few years..

Addellyn Kasherman

hardev singh

basha basha

Doesn't working Fake app

Phil Bruemmer

It works! My battery was charged last night and at 8pm today it is nowhere near needing a charge. Usually after this amount of time the battery would be around 40%, or less.

David R

THE BEST APP for monitoring/measuring battery usage. Extends battery mainly by enabling data only periodically (always 15 min. in free version) while phone isn't in use, optionally only when battery is low. But what really stands out for me is the battery history graph, which shows both the level and the drain rate (% per half hour interval), and you can get the numbers by dragging an orange line to any point in time. (You do have to buy the paid version to see more than a day or two of history on the graph.) With this, I can see that each night my battery drain dips down to about 0.35% per half hour, but after installing some new apps it got only down to 0.55% per half hr. each night. I can try uninstalling the suspect apps to get it back down again. Many of us have the problem that our "baseline" idle battery usage rate has crept up a lot over time, and often the culprits are hard to identify because their effect on overall battery usage is indirect, for example by simply holding the phone awake unnecessarily. Current versions of Android no longer let battery-monitoring apps identify which specific apps are holding the phone awake, so it's helpful to have an app like this that makes it easy to monitor the global drain rate.

Veronica Deluna

Please help I work the daytime shift by 4 o'clock its a 17% can you please tell me what to do step by step so I could stay over 50% this morning I used it for 2 minutes it says 100% in two minutes it went down 4 points 96 % can you please help

Arjun A

phone saver before installing when I charge my phone for at least 8 hours it shows full ,when i start to use it after 10 min it shows battery low. so I choose this app it definitely helps

Mike Goldberg

Running normally, no issue found Nexus 4, Android 5.1: Over time, I've tried the top 10 battery saving apps. None of them ever had these welcome words, "Running normally, no issue found." And, the ability to choose a Notification sound for "charged 100%" is important for my phone's health. Also, the UI with helpful instructions for the user is excellent.

Kiran Kakde

5 ★s but for one thing I ve been using this across all 3 mobiles i ve had - with excellent results... however, on the Samsung Galaxy Note 2, doesnt kill connections (may be some app is running in the background) and when it re-enables it somehow chooses Mobile Data over Wifi...though I bought the paid version I am switching to CleverConnectivity which seems to overcome these specific problems. A week of testing and I ll know for sure.

reea joice

The best App! Must be have in the mobile phone! Brilliyant Sam Lu.. thank you :)

Melissa Guillaume

This app was great until the software update. Now my battery seems to drain out in less than 5 hours. I've seen the mention about rooting the phone but I have no idea how to do that; I'm not that tech savvy.

Eric Tee

Only Rooted? I already upgrade my firmware to Android 5, now i cant use. How can I email to you? I dont want to root my phone and I bought your program..

Addellyn Kasherman

Works as it claims once u hv found a proper setting for ur particular device.Good work!!!

Jazz Z

Jeanne Serifos

angel rallonza

hemant naik

miguel eden

Best app thinks for this app I riot my phone and it works fine yrs!!!!!!thinks

Brian Allen

Great app! Since installing my battery level has remained high compared to previous great drop by mid-evening. Am very pleased with results. Found can also restore lost Internet on SIM associated service. Brilliant as when it disappears when out with no WiFi this is the only utility that restores my Internet. I'm going for the Pro version as Sam should be supported!

ALPHA, Abdullahi Aliyu

Android 5.0.2 Does not work on latest Android 5.0.2. Too bad.

Brandon Dawson

Much better using this app

Josh Pratt

Just what I wanted This app extends battery life by automatically toggling WiFi and mobile data, which works very well.

Achim Unawatuna

Mobile data not enable When no wifi available the mobile data will not be enabled when the screen turned on

Neil Hodkinson

Does not switch off wifi or mobile anymore Running s5 on lollipop unrooted and does not switch off data or wifi anymore

Shayne Larson

Twice as fast but don't leave to long

Veluvio J4

Excellent Awesome

Michael Miler

Great app Other battery savers have a lot of glitz, but this one is the only one that just seems to work! The others not so much. ;-)

A Google User

Samsung Note 5/ Nexus 6P Totally missed the app when wasn't compatible with Android L& M. A superb/brilliant application! Significantly improved the battery of Nexus 6P! Beyond impressive all together!

Alosious Lubinga

It's great battery saver, i recommend everyone to download

mike Mashegoana

Najmuddin Nomani

Springing Riptide

Immiko Jira

Always use it. Save my battery to be a day long!

Bhragendra Bhat P

The display gets turned off automatically It was a nice app. But from a couple of days, the battery level indicator turns off automatically. I am uninstalling this app and trying out a new one.

Rick Kometscher

WORKS!!! I've gained 1 hour of battery life. I was skeptical at first, but since I've been using it, I'm convinced. I give this app my recommendation! LG G4. ANDROID 6.0

Sarvesh Pavale

Restarting every Minute I can't uninstall this... F***ing Irritating ....i have been using since 2013...but since 2 days its not working

Twan Olfers

Super The option that activates data/wifi every xx minutes keeps you online for the outside world and still saves the battery and data usage. now even on android5, great work and super support from Sam

Joe Millers

Love it it works 100% I have no complaints anyone who does has big problem's It is GREAT

Yen Mertens

Great app, but after a while (without even rebooting) the setting Settings > Enable App returns to True when I set it to False. I primarily use it for the great battery notification and don't need the extra system optimizations. UPDATE: seems it was an error on my part since I can't reproduce it. Thumbs up for dev interaction!

J.R. Orci

Good app. Responsive developer. Just a few features I wish were implemented. 1) Auto management of bluetooth. 2) Simultaneous management of wifi when managing mobile data via VPN option. I look forward to future updates.

Harsh Bhardwaj

Wonderful! Have used this app for years and it truly works - highly recommended.!!

Paul Jr Deshaies

Really REALLY saves battery I had a small glitch in configuration and Sam pointed me in the right direction to fix the issue. I'm not going to say in how many minutes he responded to help him manage expectations... suffice it to say I was extremely impressed with his speed and knowledge. Please keep him happy and fed... buy the pro version @Sam great job!

Doom Racing

I like this program, BUT when a update comes up I have to uninstall the app to update it. I don't get why I have to do this. My old samsung note 1 didn't have this issue, but this samsung note 2 does.

Tonny Hermawan

Root feature disappear? I root my phone because i know this app works 100% on rooted phones.. on my galaxy A8 the root feature on this app missing on it.. and data still work even i have set night schedule..

Philippe Pilon Choquette

so complicated to use that i didnt actually got to try it

Reymark Abello

Nice app its working :)

Brett Michael Winston Te

Tried the 20bps, didn't work the way i wanted it to. I would really like to force the internet disconnection via VPN immediately and not wait for the traffic to go below 1000bps. Is there any way to do it?

Hali Matus

Good Long battery life....

Matthew Donegan

Uninstall How do i uninstall this app??? Tried your suggestions, only thing that worked was installing "System app remover" application. While im sure the app may be ok, i shouldnt have to almost reboot my entire device just to remove it

Mustafa Khatab

I have problem in my app. As l purchased before and shown now free. Thanks fixed now.

Tj Necrophos

Awesome app. But on my device, screen filter doesn't apply immediately. Pls fix. Tnx

Izumi Wong

Suggestion: customize button size in 'Quick settings' And align buttons at centre

Umesh Singh

Why after one week it is seen u0date A big problem with app after download ,message floated for update. What is new in few day .suggestions delete or remove older versions from Google stor.

Duane Winter

Simply the best No unnecessary features, everything works, all the time. I've used it with 4 phones, it always works, unlike others. Great app. More than doubles my battery time.

Jolomi Erewa

The Best I have been using this app for five years. It is app is exceptionally reliable, without the gimmicks. The paid version is worth every penny. Switches, widgets, and screen off are excellent. Sam has the quickest response time with regard to troubleshooting. I've tried several. This one wins, hands down. Simple, and does its job.

Naresh Kumar

Don't know how to use


The best app ever used

Aditya Jha

Draining more battery This app is draining more battery on my phone than its saving. Very disappointing results of this app.

2 Battery - Battery Saver. I've send a log to described the Classical problems in my device at yesterday. Hopefully those could be helps and could fixs as soon! Thank you. #v3.43

Christopher OLoughlin

Long time satisfied Pro user Found a bug. Screen filters can block taps on some dialogs most notably in accessibility settings. Workaround turn off filter, do the dialog box, turn filter back on... Always been a nice app. On my phone, has made the difference between 30% at end of day without a charge, and a dead brick. The color screen filters are great, too. But could you make these available when app is disabled? I think you guys did that some time back, why did you revert it?

Arya Kusma

Something is missing Two things that i really like about this app, 1st auto internet disconnect when phone screen off so my phone can stop consuming data and power when the screen off.. 2nd is the full charge notification to keep me from overcharge my phone, but lately after update my phone to 6.0 OS, full charge notification doesn't work.. Already reinstall the app and update to latest ver but it still not working T,T can u fix this? Please

haja mohideen

S U P E R B. It really saves battery and very helpful to us. Very nice.

Darcy Armitt

Helps to know Has worked fine since I have installed. Would be nice if it could notify if an app is using up battery

Mike kessner

All I can say is Wow! I'm shocked. I was pissed off every day cause my phone wouldn't last 5-6hrs in a day without dying. Installed this app and I'm going on 14hrs and still have 25% left. Amazing!! Thanks so much

Uncl Scott

Been using this since version 2 love it Never had an issue, and saves me hours of charging

Subrat Prajapati

Amazing 1st time Know SamLu long, this app this just unexpectedly increased battery life from 24hrs to 30hrs now. Bit improvement require a fast internet switch-On post screen turn on.Hope do not have any security risk in this.

Manjusha Prajapati

Great and amazed Bit surprized post using 100s of app, this does some job.battery last 6hrs more than earlier.Dont know why others cant do same.

Nancy Bochniak

Nancy B. I really like the cute voices you can pick for the alerts. And the feature that alerts to to a low battery. I've been using this app on my phone and tablets for a few years. I give it 5 stars.

Rob Snaith

Help please Doesn't really seem to save me anything, and really slows down charging. Now I can't seem to uninstall.

Izumi Wong

When I turn off both WiFi and data, it enables data at certain interval. It drains my battery. It wasn't like this.

Bryan Robertson

Devoted Android User Still the best battery management app around!

Dylan Mulvey

Shouldn't cost money I think its a waste of money to pay for this because it doesn't make much of a difference because its a great app either way.


Works out of the box. I immediately noticed a savings difference the first hour.

Cynthia Smith

2 Battery - Battery Saver Excellent application; incorporates numerous useful & invaluable tools needed to keep your mobile device running smoothly & safely. Set up to work in conjunction with your security apps. Kudos Dev - superb app & support. Thank you.

Christ Wilson Topno

Good App I installed it 3 years ago. And my surprise, it is still doing it's job flawlessly. My battery really stays longer. And due to this app, my phone samsung galaxy gt-i9082 performing well and the ui of my phone is running smoothly. Good work guys for providing us such an awesome real app. 5 stars for you :) Just a little suggestion from my point of view. Make the Screen Off widget round and slightly small. It's a bit big and square. Hope you guys do it sooner than later. Will appreciate that.

Dead Thorn

Not working I downloaded it and tried seeing if it actually made my percent of battery go down slower but it goes down as fast as my phone normally does so it means either the app doesn't work or it just doesn't work with my phone

Angel Livitas

can't uninstall helloo... why i can't uninstall this app after i download it? its not useful. my battery drain too fast then i thaught

William Barnes

Data gathering Requests information on everything privately your phone. Not acceptable.

Nivek Prioc

Great app. It can help my battery getting better. Thank you so much, Sam Lu.

Tarik Najim

I have run my S7E (MM) for several days now with & without 2 Battery and I must say that I find 15-25% more battery remaining at the end of the day! For me, a longer lasting battery on my phone is a must and I do recommend this app.

Dominic Anfuso

Ok Still using the free version but it does not turn off data when screen is off only wifi. Pretty disappointed I've tried many apps and have the same problem... Maybe a Marshmallow issue?

Shailesh Kumar

Indredible Last 6 hrs more sure shot.excellent hope do not pose any security threats.

Suhail Faruqi

Brian Bohrson

This has been one of the most essential apps for my phone's. Will always use

CW Ong

User friendly Easy to use. Clear indication

Excellent It does a good job of saving the cell phone battery

Sébastien Clermont

Used to love this app I used to love this app. It's got the best battery history out here. Very detailed and very neat. In the end I wasn't really using it for more battery life because it had none to very little effect on battery life. And no other app out here offers real constant battery life optimisation. Not anymore. I stopped using this app because it kept bugging me to grant VPN access which I did not want to give because, like I wrote, I wasn't using the app for battery optimisation anymore.

Elizabeth Baldwin

Juice defender replacement for recent android Always used JD. Always had 3 day battery life. V pissed off that Android 5 broke JD. This clever developer solves the problem.
