Battery info app with the manual voltage calibration.

It is actual for the device with a problem built-in battery info driver, showing wrong charge level. If your system indicator shows the battery charge OK - you do not need this app, no need to make negative review.

This utility can:
* get system's present voltage info of the battery (if the system returns it, it must be 4-digit value in milliVolts, usually 3400...4200, some device cannot do it)
* save the Max battery voltage you enter manually (when it's fully charged for sure)
* save the Min battery voltage you enter manually (when battery is just alive, discharged, say - just after switching on)
* calculate the battery charge % accoring to these voltage levels and show it
* notify, if battery (calculated) is getting low, and when is almost discharged (and must be pugged in for power source as soon as possible)
* save every hour battery charge statistics and show the graf chart
* optional auto-saving the min and max voltage, if it's smaller or exeeds the current voltage

NOTE: only Max and Min levels are correct, the linear calculated % values may differ from system's or other app's battery info, it's not a bug.

New added for paid version: discharge speed (% per hour) calculation and the text alert, if exceeds the limit (option).
If charging from a power adapter - the value is negative.

Alarm minimal charge level is 40%, it is 5% after the registration (in-app billing payment by Google Wallet).

So, step-by-step:
1) Charge the device battery fully for sure (3-5 hours)
2) Start the application and make sure that the Present voltage is 4-digit value
3) Set the Max voltage by "Set present voltage" button under it
4) Set the Min voltage around 3200 mV or leave the default
5) Save the settings
6) Use the device until it switched off
7) Start charging and switch the device on and set now the Min voltage to the Present one
8) Save setting and try using your device checking the charge level.

Recently changed in this version

* added for paid version: discharge speed (% per hour) calculation and the text alert, if exceeds the limit setting
* fixed: interface for any screen

* added: auto-calibration text alert now are optional and adjustable
* changed: average charge percent stored for the statistiс chart - now calculated within 10 mins, not a hour

In-app billing fix

    I'm still testing it over a couple of battery cycles but so far the free version looks good. I had a Huawei Mediapad with very strange battery meter showing 100% until almost no power left and then it shut down. I knew the battery was OK and with this app

    My Galaxy Tab GT-P3100 had battery problems and i traced it back to wrong battery callibration stats..searching for apps that could callibrate the battery,i could only find apps that needed root access or plain did not work.finally stumbled upon this app.

    GOOD: CaliBatteryl calculates % remaining battery from the difference of min and max mV Voltage. BAD: It needs an icon in the status bar. It has no widget. I baught the Pro version via Google Wallet. The pro version turned out to be without any additional
