Battery Capacity and Lifetime Calculator app for iPhone and iPad

This tech tool app calculates actual capacity and lifetime of a battery given following values:
- Rated capacity (in ampere hours)
- Peukerts exponent (also known as Peukerts number)
- At hour rating (in hours)
- Discharge rate (in amperes)
The first three values can be obtained from battery data labels or data sheets. The fourth value is the estimated load current to be drawn from the battery.
This calculator can be used to determine actual capacity of a battery and how long the battery can last as opposed to rated values. Rated values are usually misleading and they do not reflect the actual performance of batteries.
With this tool actual performance of a battery used for electric cars, solar energy panels or industrial equipment or any other types of application can be calculated.
This tool can be used for educational purposes by students and for practical uses by both engineers and technicians in the field.
Latest reviews of Battery Capacity and Lifetime Calculator app for iPhone and iPad
Only computing, does not measure the capacity of the iPhone!
This app is a fill in the blanks calculator. Basically a scam/garbage for $0.99. Screenshots make it look like it has the ability to determine battery capacity. It does not. I didnt pick that up when I read the text description. Thats my mistake.
Feel like the vending machine just ate my dollar and didnt give me my Coke. This app does nothing. Literally. No numbers. No data. Nothing!! Consider an out of order sign on this app.
In short, this is a calculator you are expected to go online and look up your model of device and its battery capacity plus the possible and actual drain on the battery in order to get any information whatsoever for $0.99I expect this to be automatic. I am very unhappy/want a refund!
