Thank you for your review. Unfortunately, this information is not available for app developers. But it is easily available for iOS itself. You need to go to settings, battery, battery health. You will have that information there. Hope that helps. Regards, Andrew ### 3/5 — Difference between Amperes vs. Amperes 3? *2020-11-25* What’s the difference between “Amperes” and “Amperes 3” app? I bought Amperes 3. Both are from the same developer and seem to do the same thing. Did I purchase the wrong app? **Developer response:** The main difference would be different interface. Also some other small things. This version should provide you with the same test results as another Amperes. Thanks.

Apparently Apple have hidden the data needed to get usefully quick data on charge rates, and you have to measure actual charge time and the app does the maths that you could instead to calculate charge rates. That’s not the developer’s fault, but they could have chosen to say so before you buy it and find out. Kinda chapped my cheeks - be aware of this before you spend your money. ### 1/5 — Unusable *2025-02-27* This app crashes every single time I try to open it. Absolute waste of money. ### 1/5 — Não funciona *2025-02-09* Não funciona no 16 pro ### 1/5 — Didn’t work on iOS 17.2.1. Money wasted. *2024-01-01* Tried on 2 chargers and it didn’t work on either. My wireless charger charged my phone from 70% to 100% with the test running and the app didn’t record anything. I tried another plug-in charger at battery 87% and the battery icon showing charging. The app says the phone must be charging (check) and the battery must be below 90% (check). The test wouldn’t even start. **Developer response:** Hello. Please try running tests when your device is discharged below 70% if you are on iOS 17. Apple added several changes that will result in slower tests and need more total discharged percentage of your device battery in order to work. Unfortunately we could not persuade Apple support to reverse this change back in iOS 17. regards, Andre ### 1/5 — Gardez vos sous *2022-01-20* Ne fonctionne carrément pas **Developer response:** Merci pour votre avis. Pourriez-vous s'il vous plaît me dire ce que vous entendez par là? Nous avons des instructions de test dans l'application, que vous voudrez peut-être lire avant de tester. Si vous rencontrez toujours un problème avec l'exécution de l'application, n'hésitez pas à m'envoyer un e-mail à support@criosoft.com. Merci. André ### 1/5 — 差评！充电满了没有提示声音？经常弹窗要求客户给软件好评，东西好了会自然给你好评。 *2022-01-18* 差评！充电满了没有提示声音？经常弹窗要求客户给软件好评，东西好了会自然给你好评。 **Developer response:** 谢谢您，对于您的评论。 为了获得声音，您需要打开并激活该应用程序。 在之前的一个 iOS 版本中，Apple 删除了我们用来从后台发出警报的功能。 谢谢！ 问候， 安德烈 ### 1/5 — Worthless inaccuracy *2021-06-21* Completely inaccurate readings and it claims my brand new 20, 30, 60, 90, watt chargers from Apple only output 10.5 watts on my new iPhone 12 Pro Max. **Developer response:** Thank you for your review. Your chargers would only work in the quick charge device range. Which is from 0% charge to about 50% charge. If you are charging your device at higher charge percentage - those chargers will not be able to supply their full power. Regards, Andrew ### 1/5 — Kein Cent Wert *2021-03-06* Wollte wissen wie meine Lade Geräte mein iPhone laden. Egal ob ich mit einem 60 W Ladegerät 18 W Ladegerät oder 10 W Ladegerät lade. Egal ob ich ein originales Kabel nehme oder ein anderes Kabel nehme. Die App zeigt nur zwei Werte 3,3Watt oder 5,5Watt. Ein USB Strommessgerät zeigt an das 3 A gezogen werden. Die App zeigt dass es nur mit 5,5 W geladen wird. **Developer response:** Vielen Dank für Ihre Bewertung. Sie müssen den Test einige Male pro Ladung ausführen, um das Ergebnis korrekt anzuzeigen. Außerdem zeigt die App an, wie viel Ladung Ihr Akku erhalten hat und nicht Ihr Ladegerät. Es ist unmöglich, die erzeugte Ladung zu messen, da Apple den Zugriff auf diese Informationen deaktiviert hat. Dankeschön. Andreas ### 2/5 — Stopped working *2023-09-30* Due to iOS17 maybe?? Tests take forever now, results are way off from prior tests with the same gear. **Developer response:** Update . 10/25/2023. Hello. Support for iOS 17 was added. Please update your app. Regards, Andrew Hello. Yes, iOS 17 broke the battery reporting functionality. We opened case with Apple but so far they are not providing any info on when is it going to be fixed if at all. Hope that we will not need to bring it to the media if they will decide not to fix it. Regards, Andre ### 2/5 — Does not support Wireless charging *2021-08-11* I paid for this app just because it said it supports wireless charging. I tried it and it doesn’t read when using a wireless charger. Please update ASAP otherwise I will request a refund. **Developer response:** Hello. It fully supports wireless charging. You just need to make sure that your device is correctly positioned, getting no disconnections from the charger, and is sufficiently discharged for the test. Feel free to email me at support@criosoft.com if you will still be unable to test it. Thanks.

Now I can test my chargers and cables. ### 5/5 — Nice app to have on every phone *2019-07-27* Very nice app, does what it says and some more! Well worth the 99 cents! :))) ### 5/5 — App helped me replace a faulty charger *2019-07-26* Great app with a lot of useful diagnostic tools. I thought my phone’s battery was worsening this past year but it turned out it was a faulty charger. Tested out a new charger and the charge speeds are back to normal. ### 5/5 — Works great! *2019-07-23* Just found out the reason why my Apple charger was charging my phone so slow. Bad wire :( Now when I can check and compare wires, few of my beautiful wires ended up in the garbage, because those were beautiful only on the outside. Thank you, Amperes! ### 5/5 — Very good app for charger testing *2019-07-22, version 1.0* I use it all the time for charger and cable testing. It works good if you want to compare chargers or just to see if your wireless charger is charging the phone quick enough. Recommended. ### 3/5 — Бесполезное👎 *2025-09-17* Покупал чтобы видеть реальную ёмкость аккумулятора. Оказалось в приложении залоченны все ёмкости моделей iPhone. Установил Аккум увеличенной ёмкости, видит только заводскую, сколько должно быть с завода в iPhone. Разработчики, вы можете исправить? Так чтобы ваше приложение видело как 3uTools видит, реальную ёмкость аккумулятора. ### 3/5 — Doesn’t work very well on iOS 17.2.1. *2024-01-15* Update: I got the app working better and thanks Andre for replying to my initial review and attempting a refund. I upped to 3 stars since I’ve been able to perform and record some tests. If the interface said test below 70% charge rather than 90%, it would solve a lot of initial headaches. How is the user supposed to know that if the app doesn’t say? Also, the tests taking >10 to 20 minutes is a long time to wait when you can’t navigate away from the app during the test. Having an estimated countdown timer or a progress bar come up after 2 or so minutes would be helpful to decide whether to continue or abort for another time. Tried on 2 chargers and it didn’t work on either. My wireless charger charged my phone from 70% to 100% with the test running and the app didn’t record anything. I tried another plug-in charger at battery 87% and the battery icon showing charging. The app says the phone must be charging (check) and the battery must be below 90% (check). The test wouldn’t even start. **Developer response:** Hello. Please try running tests when your device is discharged below 70% if you are on iOS 17.
