Battery Testing

I agree with many other users that it is difficult to use this app in the free version. The ads interrupt the process and you're never sure if it's restarting or moving forward. My five star review is conditional on purchasing the app.At a reasonable, IMO, $1.99, I decided to purchase it to test my iPad battery. With the ads gone, it is a very useful app. It ran a test that took about 5 to 6 minutes and you could see the progression until the end, then it gave me a score. I wasn't sure what the score really meant until I took a look at the history. I was glad to see that my year and a half old iPad 11 was still in the "normal" range when compared with identical devices. I expected some degradation. In the test result area, there is a share icon that will produce a summary page which you can take a screenshot of for later reference.The app also told me how much I could time expect for web, browsing, videos, etc.. It also shows a bunch of system, detail, such as RAM, the CPU networking, and, most importantly, for this app, the battery capacity. All those seemed to check out, and I found them useful. This app is definitely a useful addition to the built-in battery status.My purchase also included the iPhone version, though I had to do a "restore purchases" to get rid of the ads. I was not surprised to see that my phone, which is newer than my iPad and also gets a lot less use, scored higher on the battery test. Add all this up for the price and it is a 5 star app for me.

I downloaded this to test my battery in IPad mini 4 and it works great. It shows the max capacity your battery can hold and how much charge you are getting. It gives you a score based on performance to show overall battery health and if battery needs replacement. Only bad thing is ads pop up during the test making it pause until you clear the screen so ads should be adjusted to pop up before scan starts for accurate results.

... The first review I saw with a score of one said almost exactly what I have to say. It could be that I have an iPhone 5, and the most recent iOS I can run is 10.3.3. Perhaps in later iOS versions this app useful information. For me, it just showed me five minutes worth of advertisements and then gave me a number. I gather from looking at other peoples scores that this number can range between one and 1000. I've now run the test several times on the same battery and gotten wildly different numbers. I found a chart that said that my score is "bad." Finally I found a page that showed me available milliamp hours and percent usage, but it turned out that that was a number I could have obtained by multiplying the percent my iPhone shows in the upper right corner and the maximum possible milliamp hours of this battery if it were in perfect shape. I get no estimated run times, no explanation of what test was run, no explanation of the score and what it means… You get the idea. Useless. At least with iOS 10.
