Battery Calibration

Garbage. People scroll to the bottom of the page and report to Google promptly! This is the reason why people are switching to iPhone and or BlackBerry 10 because of liars like this!

This app does diddley squat! What a ripoff.

This app sucks .. its always says your battery is already callibrated.

I paid for it and on my new phone it shows that I calibrated it allready. DONT BUY IT, YOU WILL REGRET IT.

Does exactly what it says on the tin. I calibrate once a month to ensure battery and phone % readings are accurate and in sync together. Great smartphone calibration app. Recommended.

Fantastic

Great app

I had it and I paid because it works. But since I paid for it I could only calibrate once and now he doesn't let me do it anymore! Please fix this bug and I will give you 5 start! I have a paid useless application on my phone now!

I was having issues with my battery displaying 92% after fully charged so I thought id calibrate and give this app a try. I was suprised that it calculated the exact percentage I was off which was 8 % and fixed the Issue. Its different than other apps which claim to calibrate! This app really works and you can see the percentage you were off. Which is real nice. Great app 5 stars. !

Expensive and not cool at all.. calibrated with my S4, and made my phone more frustrating. I thought its going to fix it but then instead of 5% every hour, now is like 10-15% power lost .went to go swimming for couple hours had it on 90% when I went back to check it, drained the battery to 64%. I wasnt even using it.

Pretty sure this doesn't really do anything, but at least the author responds to questions. Always have to hit calibrate 5 or 6 times before it will work.

Waste of money. Running stock and still didn't do a thing!!!!

Don't waste your money on it it sucks and doesn't work.wish I could get a refund towards other app but this app sucks don't use it!!!!

Seems work better than the rest without rooting

Keeping my fingers crossed.

Not sure if it does anything

Good

App.

Cool app

Efficace

Right from the first try it keeps telling me it cannot update the phone, and to try again next full charge. So if you like to gamble, then purchase it. If not, wait until fixed.

Calibrated maybe in less than 30 seconds

I paid for it and on my new phone it shows that I calibrated it allready. DONT BUY IT, YOU WILL RECREATION.

Very bad it never calibrate always say its have been calebrated i hate you lier man

Works

It works perfectly.....I don't know what It does but now my battery lasts more. Great app.

One time use cant calribate no matter how often u discharge and fully charge to 100@.

I've had this app for only a few days, and it is the bomb bay!!! I'm gonna give you props!!!

This is FINALLY the first "battery" application that I have ever used that I can actually notice a positive result!!! FYI: It is extremely rare for me to rate any application 5 STARS!!!

improved my Sgs2's battery life significantly

Right from the first try it keeps telling me it cannot update the phone, and to try again next full charge. So if you like to gamble, then purchase it. If not, wait until fixed.

Everytime I exit app it effing begs me for a 5 star rating. Are you happy now?

When battery has become uncalibrated it tells me it has recalibrated (by 8% last time). Only reservation is that it's hard to tell exactly what has changed. For those giving poor reviews saying it won't work, if your battery doesn't need calibrating then it won't do anything!

I notice a small difference in battery life so its getting the job done.

Says I have already used once and try on next charge. I haven't been able to use. Waste of money and want a refund!!!!!

I've used this a few times now, very happy with it, very simple, does the job! - I like how it tells you how far out of calibration it was, for eg; 3% or 4%. 5 Stars!

Allowed me to calibrate only one time. So only 4 stars. Keep up the good work.

I went from a 1650mah battery to an 1800mah battery and it recalibrated it perfectly. Top marks! 5 stars - *edit* Will not allow calibration more than once 1* until fixed.

I got the photon with the extended battery. I used it once and it tells me that it cant do it was again. Dont buy it..
