FAQ:
*Accuracy is based on a perfectly calibrated device, which is required for high accuracy. Your device's accuracy may vary.

*Estimated values may sometimes progress up and down, but usually the first estimated value is the most accurate amount.

*Battery life time remaining means how long you can use your phone continuously, unless specified in calibration settings.

**Decimal point battery level precision is currently only available after charging for approximately more than 1-2 minutes.

What’s New

Version 1.2

- The app can now display decimal places while charging (i.e. "72.5%" will be shown instead of "72%") within the app, as long as you give a few minutes for the charging to ramp up to full speed at a stable rate.
- New screensaver mode which shows the battery level and current time at a low brightness. Ideal for situations where you need to quickly monitor your phone's battery level while charging, with the new decimal place precision.
- Added support for all new iPad and iPhone models.
- Fixed an issue regarding the calculation of the hour and minute counter.

Enjoy! :)

Accurate, needs more description

This app is like magic, predicting almost the exact time I have left before my battery completely drains. I'm like, now how is this gonna work, but now it seams pretty accurate. When I first opened the app, it showed 77% of battery remaining and about 5 hours before battery goes completely down. This is about right from my estimations continuously using my iPad. The only thing I'd like is more description for the calibration screen. I hardly understand and any of it witch is why I'm only giving it four stars instead of five.

Hi there,

Thanks for your feedback. I'll be improving the description of the calibration process in future updates.

Thanks for using the app!

Best battery for charging timr

I had used Battery Magic and Battery Doctor apps which shows the remaining charging time before battery is fully 100% charged. This is very useful because I am cautious to not overcharge my iphone, iPads or Samsung tablets batteries. Knowing the time required, i.e. 2 hrs 39 min til 100% charge helps me when I am short on time. If I need to get started and drive , I will connect my external battery to my iphone.

Thank you for developing the best battery app. I love knowing the time required for full 100% charge. In addition, it gives temperature of battery, time iphone/ipad disconnected from charging, and usage time.

I have already shared with a friend already. The app is excellent so I wanted to wrote a detailed review which will help encourage other people to download this excellent battery app.😃😃😃😃😃

Not really that helpful…

It basically tells you how much battery you have. It can say an estimation of how much time you have left but other than that, I don’t get the point of it. I can basically just see how much battery I have left. I want more info on my battery 🔋 🔋🔋

Developer Response ,

Hi there,

The app's primary purpose is to provide a significantly more precise estimation of your battery life after calibration, even up to +/-1 minute of accuracy, which is not information you can currently get from other apps or the system.

The app also displays a decimal place after charging and leaving the app open for a few minutes - 72.5% instead of 72% for instance - which is a helpful way to see that your phone is topping up its battery, and visualise how fast your phone is charging.

Hope that helps! :)
