Description:
Battery Monitor, the most accurate battery life monitoring app on the App Store. With its simple battery life calibration, you can get estimations with down-to-the-minute accuracy (±1min)! It also have a handy widget to access estimations anywhere!
This app contains calibration for battery usage, battery charging time and much more, making it one of the most accurate on the App Store! Don’t download those clones you find everywhere, download this app now!
Features:
• ±1 min battery life accuracy*
• ±1 min charging time accuracy*
• Simple interface, easy to use
• iOS Widget for easy access
• One time battery calibration
Download and enjoy! :)

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.
• Battery life time remaining means how long you can use your phone continuously, unless specified in calibration settings.
• This app’s charging speed calibration is currently only optimised for iPhone. Charging time accuracy may vary on iPad.
• Even if the app doesn’t work as expected, you’ll still get is around ±10 mins accuracy, and is still one of the most accurate on the App Store.

Hi how do I get the its widget to work?
I switched my battery from a 2900 mA hour to a 3500 mA hour is the calibration going to compensate for this bigger battery? iPhone 7plus
Nice app……
Hi John,
The app should be able to compensate for the changes if you perform the calibration process again after changing your battery.
Thanks for using the app!
great app!
only comment i have is
i would like to see temperature reading added.
Thanks
why is not this app working
Hi there,
What do you mean the app doesn’t work? It doesn’t do anything other than showing your battery level and predicted time remaining. It doesn’t really have work to do.
Thank you for this app, it is the most accurate I have seen to date!
Congrats

Can you shed some light on the calibrate section of the app. What’s that and how to use it.By the way clean app. Thanks.
Hi Roy,
The calibrate section of the app allows you to calibrate the app’s calculations of the time remaining till battery reaches a certain stage (for example, calibrating the time estimated for the battery to drain).
Tapping on “Battery Usage Time Remaining” for example, will allow you to start a calibration of the calculated time of how long can your battery last. It simply measures the amount of percentage drop (when your battery is within the range of 60%-40%) while you use your phone and estimates the rate of battery drainage, which then updates the calculation of the time in the large “xh xm” counter in the main screen of the app to your usage. This process is pretty accurate and if calibrated properly, is able to yield accuracies of within ±1 minute, where your phone will run out of battery almost exactly as stated by the app.
Hope this helps! :)
Every time I go to bed and sleep I charge my plug my phone in the battery charger in the wall
Hi,
Is there a Way to see which apps that are using power?
I have a problem with drainage and it would be Nice to see If a particular app drained in the background .
Best stef
Hi there,
Due to iOS limitations, the app cannot help determine which apps are using too much power. However, you can go to iOS Settings > Battery > Battery Usage and you can see which apps are using the most power on your phone.
Hope this helps! :)
Love the app so far, but the clock seems to be off somehow, possibly due to Daylight Savings?
For instance, I’m in Philadelphia EST, time is 10:54am, and app says it will be fully charged in 3 minutes at 11:57am, but it should say at 10:57am. .

Hi there,
Thanks for reporting this issue. Is it that it consistently remains one hour off or occasionally?
Maybe I didn’t allow it time to calibrate. Now it is saying it will be another 52 minutes trickle charging by 11:51am, which is correctly 52 minutes from now.
So it looks like it is working. I’ll reply to this post if I see a clock error again.
Hmm… Based on your reply, this looks like an error with the “hour” part of the calculation, since you said it now states “11:51am”. Hence, I can conclude the 11:57am you previously saw is probably the correct calculation while the “0h 3m” is wrong. For now, you may rely on the time rather than the minutes and hours while I fix this issue.
Thanks again for reporting about this! :)
Love it and the best app I’ve downloaded so far and I tested a few dozens of them and this is just simple and great
One issue though not optimised for iPhone X
Pls do it asap
Eagerly waiting…..
Hi,
iPhone X support has been added. Thank you for your feedback!
