Why so many ads? Used to be a great app however I can no longer see the whole screen of details as the ads cover up battery status. Also after only a week this 4mb app has downloaded 6mb of ads... WAKE UP developers! Not every android device has a 1024x768 screen and free internet downloads. My provider charges $2/mb for excess data. Your app is invaluable when it works but the ads arent worth that much.

Charles Hu

Gmail stopped syncing For some reason, since installing this app, my gmail doesn't sync anymore, even manually. Other Google features sync, just not gmail. Uninstalling the app solved the problem. This app must be blocking something. If there's a skein, I will reinstall this.

Anthony C

Great App For those who understand the inner workings of the battery will benefit having this app. Works great on non rooted phones but needs rooted to get the statistics data. No fault of the app, blame kitkat 4.4 and above including Lollipop 5.0 for that. Technical Service is outstanding, top notch.

Don Davenport

Great App I use this all the time. Phone tends to heat up when used as a GPS and this helps determine what is going on when charging. Above certain battery temperature charging rate drops off.

B Wishloff

Helpful App More information then I need in many areas

Steven Court

Ruined by adverts Was a good app but now full of adverts... I've now removed app.

Eric Snyder

Gobbling up battery? Battery usage spiked recently on TMo note3. Checked active apps and this has 7mb and constant 1.75 to 2% CPU. That seems like a lot. Recording history every 10 min. I think it must be ads

Bruno Freitag

really usefull one of my std apps, also showing whether a charger is any good, works on most devices Nexus4,5 10, samsung notes, not on s5mini

Matthew Simmons

Inaccurate Loved this app on Samsung s4, however now on LG G3 running Android L the app shows discharging and yet the battery percentage in the task bar slowly goes up. Needs more work for g3

Nick Campbell

Horrible ads Developer is too greedy, explodes with a full phone ad second after you open it. Plus it's no where near as nice as current widget.

A Google User

Star app and developer Thanks for a great app! Do you every sleep with all these updates? I am buying your app to show my support right after this comment ;-)

Bobby Mason

Genius app. Accurate app. Great settings. I wanted to see if my new phone charger was really putting out the milliAmps it said it was, and now I know.. Awesome app!

Theodis Wright

Could be great, but... You don't get any chance to actually see the app work before you are bothered with ads to buy the full version. As soon as I open the app to configure it, I'm being asked to buy the full version. How about allowing someone to see how the app works (much less configure it) before asking them to pay. As someone who totally supports a dev being compensated for their work, this is a total turnoff that is not worth my time or money.

Noon Sod

Not accurate but okay On my Samsung Note 2, this apps works, i can see fluctuations and i believe it is returning values read from the device. But the respond is delayed and fluctuations too big that lead me to believe the reading is inaccurate

Willem Jacobus Grobler

Bullsnot!! This app is 100% incorrect. When the mA reading is negative it says the battery is charging which is NOT correct!! When your battery is charging the mA reading should be POSITIVE!!!!!

flo f

Very useful! It has great many features in the free version. It was really useful for debugging a problem as google play services was draining the battery. I decided to buy the pro version, the developer deserves it.

Cristian Gadalean

I don,t know for sure but this app drained my battery in half day, and my s4 mini was on standby

Alan Field

Used this programme for yonks, two thumbs up from me.

DJO Manchester

Great info - but drains battery Really useful app. Great info but draining battery which out weighs benefit. If it could be improved be great

Scott Collier

No text only current status bar option

Ondrej Varoscak

No support for Xperia Z3 Showing nonsense mA readings...

Nazri Ba 03081978

I very happy after using this application thanks

TJ Steen

Why can't anyone make a current app? Says my flow is 268700mA.

Sherif Salem

Is there any way to measure the charging currant?

Arnis Tarassu

Almost perfect Does run at background and remembers everything. Would be perfect if it was possible to see how much do chips in smartphone consume independantly (GPS, WiFi, BT, Cellular, camera, LCD background)

Mark Endres

Charging info inaccurate Shows rate of charge to be just 1mA regardless of whether I've connected the std charger or 3500mA fast charger. Samsung Galaxy S5 Active.

Nitesh Mundhe

Ok app Does not detect polymer battery. my tab has 4000 mAh polymer battery. but it shows 1000 mAh Li-ion battery.

Ambar Hegde

Excellent app to diagnose battery issues. Love the split graphs feature.

santosh chavan

its amazing app thanks

Ratthanin Wartcheeranon

Too complexity but useful

Donell Brown

Pure Spam Its spam phone to a point of master reset


Good app Plenty of nerdy details.


Battery monitor

Jeff S

n7 2013 - charts unusable sporadic - 5A, current spikes make the r charts useless.

blue light

No more fake mah battries now you can know what the true mah readings are for your batteries

Ivan Reede

Battery monitoring app Best in it's class.

Phumin Boonsorn

This app let me know my charger was broken

Benrie Fourie

Does not work at all In stalled on my s2, Nexus 5 and s4. It calculates mah by measuring mA?? No!!. Why does it want to know my mah rating of my battery? If I change my mah rating in settings, the " measured" mAh CHANGES !! This is just an app to show adds

Michael Hird

Notifications didn't work after update in May 2015 After the update in May 2015, non of the notification icons will load. I get a parsing error. Samsung Galaxy S5.

Maarten Deen

Nice app, strange graphs The app is nice and useful, but the graphs have a strange layout. Y-axis with a unit division of 46.92? How is that normal? And usually the maximum value of the graph has no relation to the graph that is shown. E.g. the graph for %/h now has a maximum of 299.16 (%) but the largest value displayed is no more than 50%.

chip siskey

Been using for years. Still great. Thanks!

Patrick Ferrer

Simply the best! Got it all. Even the amp measurement when using different chargers. Loved it. Been using for a very long time! Never failed me

Umesh Mohite

Still trying to get familiar with it.

Johnny Rose Carlsen

Too many ads and a bad UI

Bryan Omarion

Important If your battery charges for long hours this app helps with every possible reason out there

Vincent Tan

Not work for Note 4 feature Zero Lemon Its happy to see this apps design for note 4 feat zero lemon 10000mah internal battery indicator. But its not work . After reached 1% , i pull out the battery & put back its show 50% balance , that mean this apps only detect 5000mah. Or maybe every time i plug in i press the change battery capacity to 10000mah make this apps calc the balance 5000mah as 10000mah.

Dwight Moreland

Amp dont work. Lg stylo android 5.0

Chuck Hull

Works perfectly. Great help in evaluating chargers as well as app power usage. Installed on many devices without problems. Easily customized monitoring and interface, alerts, etc.

Mike Ryshkov

Way better then du battery this actually displays my extended battery which is 10,000 mah thank you !!!

Russ Miller

battery widget Works on most power related issues.

Blip Baker

Great features! Awesome temperature monitor! Easy to set to Fahrenheit! Thanks!

Lars Bøgild Thomsen

Doesn't work on my OPPO R7 Always had this app on all my Android devices, but doesn't work on Oppo.

Shubham Sharma

Complete and the best! Never fails. Has everything you need, and then some.

William Poznansky

Was ok. Broken after last update Was working great until the last update. Now notification packages for force crash on my Nexus 9 and no longer work.

Ramkumar S

Nice utility Useful one that helps to better understand usage, set alerts etc

Arun G

Add material design please Very professional .lot of options and customizations

Chandan Bisht

Battery I have a 4000 may battery but it shows only 1000mah

Tye Cerato

Very nice tool Works well

Lev Pavlov

Almost great, sometimes too inaccurate

Dustin Thurston

Great Great other than I'd like to be able to make out the midnight vs noon time markers in the charts. It's not clear whether root is needed to install the statistics app or just for the app itself to install the companion app. The copy from folder is not accessible without root and an alternative download is not provided.

Techdude Sonic

It's OK but ..can't remove battery icon It's OK but can't remove the battery icon on the left of the status bar up top

Jan Eli Padilla

It's the most useful one. Not the simplest to use but really it's the only one that provides me the level of information I need to know...

Jonathan Bastin

Just works Gives loads of I formation and it just works what more do you want.

Syed Sab

Not displaying charging current. Uninstalled.

El Pirata Arellano

It's a nice n useful app n good have in ur phone... It helped me a lot...

Joses Ian Salagantin

super great very helpful in choosing the right charger and USB cable

Hans Pille

Widgets no longer updated! And that makes it useless.. (it was excellent, until now)

Azhar Fauzi

Not Working Not Working on Asus Zenfone 5

Ciro D

Very good and accurate app, with a lot of data available about your battery, consumption and history of consumption

Zbyszek Sobolewski

Very useful application

Baker Field

Pop ups on this app asking for personal information? Not a good thing.

Jaime Tayag

Best option Not perfect, but the best battery/charge app there is

Irfan Ahmed

Nice Battery App So far so Good. Need more useful options

Bryan Chan

Help monitor long term usage Like the ability to look back over several days to see if new apps cause drain issues.

Hatayumi Nakano

So far, great app. Simple yet extremely useful. No unnecessary bells and whistle, love that fact.

Thilan Perera

Not working.. Useless.. Not working on Galaxy S4

A Google User

Support for QC2.0? In addition to current as shown in history, is it possible to add charging voltage or QC2.0 status as well. Charging at 9V and 5V makes a great difference!

Tom Niemczewski

Great tool! I love it! Best tool to know what is happening with power and battery in your device. I love it! Thank you!


Can't figure out multiple batteries. Paid feature?

Doc Matt

Great, accurate battery monitor If you want to know how much capacity your batteries are really achieving this is the app. Excellent battery monitoring and good graphing and data logging support. Five stars for functionality but it loses one because the user interface is a bit messy, with no less than three different settings menus in different locations. Grown organically, in other words.

Vincent Tan

Note 4 feature Zero Lemon pending update. Its happy to see this apps design for note 4 feat zero lemon 10000mah internal battery indicator. But Samsung note 4 only can max detect 50 hours , its suppose is 75 hours. Can u solve this issue ?

Mohit Kumar

Does not show current Only reason I installed this is to check charging current. I used to see it on my other mob some time bak now I can't. Its useless for me. Uninstalled.

Adi Rabadi

Great app Use it to keep track of battery life.

Jim Csabi

Great App Best battery monitor app I've ever used. Great attention to details.

Carbon Copy

Really a whole lotta app for free! This has a fantastic amount of info & features for a free app. I will be going "Pro" on payday! It is that good. It took me a while to go through all the data, but it is really useful to determine what is eating your battery and when. Thanks for your great work Dev and keep going!

Max Rebos

No amp flow on S7 Does no work

David García

Does not work fine on Marshmallow. The flow gets stuck and doesn't change if plug/unplug charger,and this way I don't know whether is charging properly or not.

Woo Woo

WTF?? After connecting to the mains my mobile started discharging instead of charging

Ruben Alvarado

So far so good. Works incredibly well with Zerolemon 10,000 mAh for the Note 4!! Was worried about the never ending 5% screen dim, but I think this just fixed that! Will edit it later if anything changes, but let's hope not.

s0me Us3r

Issue on Android 6 Real time estimate show "n/a" after upgrading to Android 6. 5 stars and pro version from me if it will be fixed:)

M Nahata

Doesn't work on ASUS Zenfone Doesn't work on any ASUS Zenfone. Tried on my Zenfone 2 and my wife's Zenfone 5. Same result. Please fix.

A.H.M. Asadul Huq

BMW is good for galaxy S5 The widget is good and useful. Can you provide me histories/statistics of other S5 users so that I can compare my data with other s5 users? BTW, how can I export history data for studying my battery condition?

Ry Dog

Idk Used this to test cords.... Fail... It gave different readings time and time again went from way positive to negative Idk maybe my phone has demands that are all over the board. But I was using task killers, restarting phone, trying all kinds of combinations and nothing makes sense

Chris Swyka

I think it's all included with 3C toolbox. I'm not saying, I'm ...just sayin.

Muhammad Saeed Saeed

Loved it Very useful apps record complete history of battery like voltage current power watt per hour we recommend to friends you must be install. Thanks to creater.

Marco S.

Fantastic app Together with its notification packages, this app is incredibly useful. Great job!

ga r full

does not read pixel c specs correctly or give charging amps

Gyaneshwar Gupta

Excellent monitor for battery charging

Riley Cassel

Meh, not really usefull but at least it's not actively bad

Monirul Islam Babu

Really good

Myra Glina

Awesome! I love it so far!

Ming Lui

Love it that displace the voltage

Anthony C

Great App☆ For those who understand the inner workings of the battery will benefit having this app. Especially on rooted phones. It works on non rooted phones (minus some advanced features), especially with Android v5.0.Technical Service is outstanding, top notch.

kira yamato

Galaxy note 4 n910c android 6.0.1 Pls fix the ad bug, after the ad pop up i cant click back button to close the ads ? I must force close the app and go in again

High Touch IT

Neutered by update V3.17.1 on 2016-06-18 disabled historical voltage graph without disclosing this in the change log. Dishonest update.

Mario x

Marshmallow Historical record log is missing in marshmallow. Any settings i need to change on my part?

FH NEHA fhneha

nokia xl battery support thinks

Kevan Banngertir

Crashes Forces closes now on 4.4.4

Pat Traynor

Perhaps the paid version is good, but I find that the free version is pretty bad. The update rate is terribly slow (must get paid version to speed it up), and ads often go full-screen with no way to dismiss them without going into the task manager, shutting the app down and restarting it.

Roman Berger

Great battery monitor

Gyaneshwar Gupta

Excellent monitor for battery charging

Charlie Rangel

Worked great on my Galaxy S5 but not so much on my S7 Edge The charging rates as far as time to charge and charging rate were excellent when I was using it on my Galaxy S5, I could test the speed of the different chargers I was using and how well the cables I used charged as well. Now that I have my Galaxy S7 edge the rate and speed are wrong. Is this app not compatible with the Qualcomm 2.0 chargers? I have one in my car and the one that came with my device at home. Are you going to update the app to work with new charging rates?

Victor John Lewandoawski

The best battery monitor ever This app provides you with all the information you will ever need. This is such a great addition to monitor your battery's health, with knowledge as to when to charge ur Battery & when you don't have to. Great ? app,should come standard with all cell phones. FOR A ZTE Z970 CELLPHONE.

Robert Edge

Love this ap! Works great on my Galaxy S5! I use it primarily to monitor the rates of charge and discharge on my phone battery.

Marwan Kaddoura

Doesn't support all phones No support for Xiaomi Redmi note 3 or note 3 pro

Chourdakis George

Most complete and honest batt app out there..

Hridoy Khan

The best app

ahsanul karim

Just owsome

Poojan Patel

Perfect Best for all kind of battery stats

Hasaan Zia

Accurate Current Input Gives accurate current input in mA , that is helpful in determining the cable quality, usage and current loss.

David Herrera

Always "Missing data for x hours"

Anthony julson

This app helped identify a poor quality usb cable. That alone is worth it!

Yan Walando

Slow after updating loading history now takes too much time. The app doesn't showed up at the notification bar although i already set it up from the settings menu. The UI was good, simple, ease the eyes for looking at the submenu. But after updating the menu becomes too complicated. I dislike the updates. Please fix these.

William Poznansky

New name and it's broken again. Can't install any notification packages on Nougat. States it failed because unknown sources isn't enabled even though it is. App creator is more concerned about getting constant ads up instead of a functional app. Used to be one of the best. Not anymore. Not the first time this has happened and won't be the last I'm sure. Time to find a new app.

Clemon GoodRich a.K.a. BLACK ICE

Very good app for battery Recently bought a 10,000 mah Zerolemon Battery .. This app was useful in telling me more about my battery charging/discharging stats !! Was also able to input 10,000mah battery capacity .. far better accuracy !!

Adrian Staunton

Stopped working Just updated to nougat and stopped working

A Google User

I've used this since my first android device... Samsung Galaxy s2, s4, Note 4, a constant and reliable favourite app. It even helped me troubleshoot battery problems on the s2 and s4. Thanks!

John Lamberton

Unable to close advert after it pops up Advert won't close down when pressing x in corner

Pip tremaine

Battery guru of apps The best out there. Gsam is the only one that comes close but it don't even have all the battery features this does.


Detailed battery monitor Even without rooting your phone, this application can monitor your battery usage. Ads only a small bar at the bottom and occasional pop up when opening the app itself.

Alex Boreham

Good but there's a bug I love this app and how informative it is. However, it doesn't show the mA flow, or the time left. Is this because I'm on the Nougat beta?

Coherent Abstractions

Very useful it had decent accuracy with battery ma usage and estimated charge time was within 1-2min accuracy, however battery drain time was way off on all 4 different calculation methods although it does get more accurate after a few days, battery capacity measurements where very close to accurate, realtime logging and graphs are great but could be more tunable and searchable, giving usage permission wasn't posable as app did not appear in list, but root companion app worked on Samsung s5 (root) with marshmallow.

A Google User

negative mah rating while charging phone on fast charger. (redmi 3s prime ) The earlier versions use to be much better, hence uninstalling it.

Souvik Roy

Galaxy Note 4 - Android 6.0 Missing Data on history. Please fix the bug. I also emailed with Screenshot.

A Google User

Great app but ads are now unclosable, have to force close app. Perhaps marshmallow problem.

the sim

Navigation tabs still missing Please help.. I keep resetting navigation bar but it doesn't work. I've lost almost all my tabs especially app usage.

High Touch IT

Neutered by update V3.17.1 on 2016-06-18 missing historical data for over three days after update.
