Battery Testing

... 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.

This is a cool app to test the power that your cell phone battery is putting out. I just replaced my battery and wanted to check to see if it was in fact a brand new and powerful battery and this app give me a good high score, in the low 900’s so I'm a happy camper. Thanks to the developers of this app. Good job. There are a quite of few adds within this app, which isn’t bad because you have to wait a couple of minutes for this app to fully scan your battery and you have something to look at something and waste some time during that period, I mean they need to make their bread some how.!!!!!!!! Its better then having to pay for an app. Add it up all you want...

My battery drains within hours, so I wanted to test it. I tried this app. The “tests” this app ran were 15-20 seconds long when it is supposed to take 5-7 minutes. Something about that seems fishy. Then it gives my battery a score in the 700s and tells me I have a battery that will last for 9 hours of web surfing time. This is wildly inaccurate since my battery went down 3% just using this app. Side note: I had no other apps running at the time of the test and have previously taken many steps to reduce my battery drainage. So the 3% drainage had to be mostly due to this testing app. Clearly my battery is worn out and there is no way I have 9 hours of web surfing time. This app is useless.

I have a several year old 5S, that the battery will only last about two hours. Erase the phone new operating system load, ran test and the tool reported 640. I went and had the battery replaced and the score went to 550, so I told them their battery was bad and had them replace it again and the score went to 500. The phone stays charged all day now New battery, although the app reports that there is no battery life. This app is a waste of time and effort, and there is no place to select feedback to connect with the developers, so I’m done wasting time with this and will move on to a different tool.

You'd think the developer could find at least one colleague who can speak English. "Estimate time for specify function" is not a good look. When I see that I have available 7 hours of "web broswing" (sic), I learn that the developer's attention to detail is, let's say, less than encouraging. I certainly wouldn't buy the "Pro" version as it stands. This seems to be an attempt at "crowdsourcing" test results for the sake of comparison, but it's hard to decipher the results. What does "742" mean? Nice eye candy on the charts, though.
