1. 5/5Works great

   All these people saying it's inconsistent have zero knowledge of how battery capacity is measured. Yes, the readings will fluctuate, but it doesn't take a genius to know you can just take the average of the readings, which is made easy by the chart and history features of the app. For a true capacity test, you'd have to charge the battery full and discharge until it's empty while watching the current draw over time. iPhones can't really do this very accurately, so inconsistent readings are not the fault of the app. The app is just reporting what the phone is learning about its battery. Under high draw (such as an increased brightness) the voltage sags and the phone has to guess whether it's the battery's internal resistance or it's actually used up it capacity and lowered the voltage. Apple never meant for the user to see these readings, so they fluctuate and aren't really user-friendly. This app just reveals these measurements to give an estimate on remaining capacity. It's a simple, easy to use app that does exactly what it's supposed to do to the best of its ability.

2. 5/5Custom name for the AirPods Pro case is a bonus

   I have used similar apps on macOS to help monitor the values of my connected devices, but they seem to use some other technique that drains the battery quicker than they should. This app seems to only update when you requested to, by turning off, background app updates, but also you’re able to make custom names for your devices so that you can figure out which is which. I own two pairs of AirPods Pro Gen 2 and I regularly switched between them, but I’m only able to name them on as a group, but the case itself remains unnamed on many of my devices. Quickly being able to take a glance at it here on the iPad I can tell what battery status they all are and which one. Apple‘s battery tool just shows two cases with the same name. Even though I’ve renamed the AirPods to different names. I purchased the no ad version as ads are just against my philosophy, I need none of the premium features at the moment. I appreciate the one time purchase option over any subscription.

3. 4/5Great app, only too many ads

   This is a very accurate application, i always use it to check the battery on my airpods since sometimes when opening the case it doesn’t always display it on my screen. The only issue I have with it is after i view one different tab and go back an ad is played, like every new action, an ad is played. I dont have a problem with free aps displaying ads, considering it is a free ap and it is most likely the only way they earn some sort of profit. I just dont like how many times it is showed while using it. Other than that, it is a great tool, it updates constantly so it gives you a very accurate read on percentage, theres more to it inside that i havent exactly explored, but so far i think it is a great app and i definitely recommend.

4. 1/5Not accurate!

   I downloaded this app a bit ago and found out that there was discrepancies. I have a fairly recent Refurbished iPhones 6S. I was getting several different readings in the battery wear level every time I opened the app. So I started to test this. I got readings of 7% Wear level (Which matched my iPhone measurement), 13% Wear level and 18% Wear level. I left the app open to see if the reading would change back to the previous reading and sometimes it would and sometimes it would not. I tested this in a three hour window. I also tested it for several days and got the same results...Very inconsistent readings. So at that point I figured the app was pretty much worthless to me and I deleted it. I just installed it the other day again to see if maybe things had gotten better with the app. I got the same results as previously. So I’m going to delete this app again and just use the reading I get in my iPhone settings. I was sure hoping it would work better.

5. 3/5App appears to be inconsistent.

   The main reason I got this app is I wanted to check the health of my battery. It’s showing that I’ve only lost 3% and the iPhone 6 is almost 2 years old. So it proves that Apple should not be throttling my phone down with iOS 11.2, can’t wait for the 11.3 update. Now five days later I just ran it again and it said there is 0% wear on my battery I then installed it on my wife’s iPhone 6 because she’s had battery issues for the past year. It is showing that 20% of her battery life is shot and her phone is 2 1/2 years old. She was having issues yesterday and I ran it again last night and now it says the battery is 37% shot. Because of these inconsistencies a knock this down to a three star rating. Best thing to do is probably run it over to the Apple Store have both of our phones checked.
