## Amperes 4 Reviews in United States

### *---- "Fraudulent Aop"
Developer ONLY tells you after purchase that Apple has greatly reduced their ability to perform metrics on your devices battery.  So you get nothing, while they already have your money.
-- BitMangler, 2024-11-26

### ***-- "Great at testing chargers, but timer alert is off"
I have found the app great at testing wireless charging, but with a few issues.

Others have mentioned that when testing, you get no indication how far along the testing is.

In addition, after clicking start., it can take awhile (enough to charge 5%) before the test actually starts running.

Lastly, it’s really important when comparing chargers to test them at the same battery % on the phone (since iPhones charge slower at higher %). There is a timer function to alert you when the battery hits a certain % to account for this. Unfortunately when I set mine at 30%, it alerts me at 26%. Not so helpful.

### ***** "used for YEARS"
and i still enjoy it even though its not what it used to be
-- midwestnocoast, 2024-05-23

### *---- "Never does anything"
Click Start test and it just says “Starting” leave it there for 20 minutes never does anything. Tried multiple times, reinstalling app, restarting phone, everything I could think of to get it to work and different chargers too. Wireless and wired.. it’s always been this way even when I bought the app over two years ago when I had iPhone 11 Pro Max IR but I came back to try it again and still never does anything just “starting” .. This time with my iPhone 13 latest iOS 17 ..At least the free app worked sometimes if u let an ad run
-- AllYourMacsAreBelongToUs, 2024-04-13

### ***** "Was awesome !"
Too bad Apple killed it.  🥲
-- gregraygun, 2024-03-16

### ***** "E for effort"
Getting struck down by Apple 🍎.  Feels bad.
-- Diray Acosta, 2024-02-14

### ***** "Nice app"
I got a new iPhone 15, and am using this app to establish baseline measurements with a battery at 100% life.

I ride a motorcycle, with a phone mount between the handlebars. Years ago I added a cheap qi wireless charge pad to it for my iPhone 11. When the iPhone was new the wireless charger was able to stay ahead of the power demands of the GPS antenna, running Apple Maps and/or SENIC navigation, as well as the Bluetooth link to my helmet. This past year with the iPhone battery aged to 70% capacity I noticed the qi charge pad could no longer keep up, and the iPhone slowly discharged as I traveled down the road.  I got this app to let me test and diagnose the devices, but that large pothole in the road dislodged my iPhone from its mount in heavy traffic. 

I got a new iPhone now – and a case with a tether, to go with the new built in wireless fast charger phone mount. This app is giving me good information to compare with several years from now when this iPhone ages. 

My initial impression:
The screen is static, giving no indication of it’s even working – until it puts up a banner saying the test has concluded. Perhaps the screen could have elapsed time ticking off the seconds, and a line of 5 lights could progressively turn green as the percentage of charge rises. That would keep the impatient user from aborting the test early out of frustration. 

Aside from that, I like it. It’s a keeper!
-- Bradiac, 2024-01-19

### **--- "Warnings are too late"
The first thing I saw after I bought this app:

“Due to some limitations in current versions of iOS, it's impossible to obtain charging results directly from the system. Therefore, Amperes uses the only available but slow method.”

Isn’t this something I should have been told before I bought the app, not after?
-- tenth33, 2024-01-12

### ***** "NA"
NS
-- Volwr88, 2023-12-09

### **--- "Not as described."
The app description should be updated to reflect that it no longer measures charger and cable performance as advertised. The app developers tell you this AFTER you’ve paid, not before, and that’s bad business.
-- PedalingAstronomer, 2023-11-18
