Good app This is good app but I had faced a problem when I was done with calibration and my battery went to 13 percent my phone was suddenly off and it was not turning on by power button I had to plug in my charger n then it was turned on I m using s4 i9500 and is this normal or something wrong with my phone or battery? Kindly ans

Sprint Note2 This is one of the best and easy batt. calibration app. I highly recommend. I change roms on my note2 and time to time upgrade and stay current with my 4.3 rom. I started getting poor batt. and never did I charge to 100% before flashing. Been trying different apps, but this one was it! If you have a sprint note2, you will be happy with this and see huge results! My phone never charged completely and didn't even last 18hrs. Now I get 18hrs. and only used 1/4 of the battery with same usage as before.

Nice one So far so good... im on i9500 and since doing the calibration process after rooting, everythng going stsble again in terms of battery drain.


Samsung Galaxy Note 3 Rooted Hey Miguel, after i calibrate my Note 3, the batterh drain percentage is insane, my batery last now only a few hours.... :(((( i kill mg battery or what ?

The real deal! I had my doubts. First of all the app has not been updated since March 2012. That's usually a bad sign for me. Then there are some negative ratings. But I used it on an older rooted phone where I knew the battery was not functioning correctly. It would get to 40% then suddenly shut down. So I downloaded the app and followed the instructions to the letter. Then it seemed like it did not work, because the same thing happened after the supposed recalibration. So i repeated te process twice more and WHAM! It worked!!! I also thought that the battery would last the same amount of hours just with the meter properly metering down from 100% (fully charged) to 0% (no charge). BUT NO!!! The battery lasted almost 6 more hours before the phone shut down. So it actually INCREASED the usage time. So my advice is: 1) make sure your phone is rooted; 2) follow the instructions to the letter; 3) repeat the process several times! The other thing I did after each reboot was to remove the.battery and then immediately reboot again. I will tell you that I was surprised that the battery gave more usage. I was not expecting that. But it did!

Annoying sounds Installed and launched, app immediately woke up wife and cat by playing high volume pointless sound. Like online ads, never play sounds not asked for!

Samsung Note 8 after reboot the device, let the phone fully discharge --> is it mean I have to do it until battery 0% like the others similar application. Need your response, thanks

Samsung tab 3 There is no word for it, thank you guys, I was desparated for two days, last night I didnt slept, trying to restore my tab. Than I found this app, left the tab charging until 100%, than I hit the calibrate button and thats it, my tab is working better than when I bought it.

A Google User

Does exactly as it says Downloaded this app a while ago. After charging to 100%, I used the calibrator. My phone seemed to regain some battery capacity after that. Calibrating your battery once in a while is a good idea, and this app makes that process very easy.

Gmeja Rondo

Not working How do i get root permissions? App won't work. Help please. Ma battery is badly off.

Hmmm... The jury is still out, I've used calibrators with my other droids seems like they don't work!!! Don't think it did anything, I feel like it gets stuck on certain percentages shoots down a bit!!! Does it take time to catch on???

Sachin Saini

Used it since cm7 day's Low rating people here are not reading properly. Please this app for deleting battery stats file that reports wrong usage to your phone . this app can't make your battery better I sense of repairing..

A Google User

Love you! Very good you safe my battery I love you guys!

Michael Puniansky

Yeah! Grate app. I used it and it is very simple. Really increases battery life.

Rob Wills

Simply works Charge battery fully and then run this - it really does work. 1 day 19 hours on standby with battery at 95%, on an 18 month old HTC Sensation. Brilliant.

A Google User

Really nice app. Now my battery can be discharge till 9%, before it's 40% and the device suddenly turn off.

Anna Kay

I guess... Ok i guess...tho i don't really see a difference in battery performance after Calibration.

John Bryan Guiao

Hi? My question is if i can use it, without installing any custom ROM ?

A Google User

steve millard

Kamotse Pettigrew

Great job I've used several battery calibration apps and this one is by far the best. Thanks for creating it!

A Google User

Waste How can calibration increase battery life ?

A Google User

A Google User

Awesome Awesome.. Work great !!!

Jeremy Noyes

AVOID! E4GT Blue Kuban ROM (rooted) Needs more info and more tools. Ask it does is make things worse. Younger been warned.

Juhan Jufri

Great app Hey noobs out there. If you don't know what is root then don't download this app and start giving 1 star. All it does is calibrate/correctify your battery back to the right state when it is full just like calibrating your gyroscope.

Nicholas Honer

Worthless You need to add (ROOT) after the app name or something your the second one I found utterly useless. People do have devices that can't be rooted.

John Reed

Galaxy tab 3.08 Does not seem to work.

Andrei Lorenzo

Rooted MyPhone A919i Very nice calibrator. I love it!

Martin Cigorraga

Low ratings I can't understand why this nice little app has a so low reputation... Oh wait, yeah, I believe I got it: most of the reviewers are plain stupid and believe this app may be some sort of battery saver or battery fixer. I wonder how the make it through they day alive... :facepalm:

markus Cee

The best I used this app before, and I have to say, it is by far the best battery calibration app out there it most definitely works!!

Lance Wilson

Great app Does exactly as advertised. Great app for root users and developers.
