Amperes Battery Charging Lite 4+

Good but could be improved!

It monitors the charging rate of your phone so you can compare different chargers, leads, etc. Tests performed over a minute or two it takes for the battery to increase in charge level by at least 2%. Like 53% to 55%.

Results reported in milliamperes but does NOT use the conventional abbreviation of mA but for some unknown reason displays MAMP. That does not inspire confidence.

I think it estimates the charge rate by change in charge percentage reported by the iPhone, the specification of the battery capacity, and the time taken. So okay for comparisons of leads etc but maybe not good as an absolute reading. Also gives WATT value as it knows the battery voltage.

Again unconventional in that the units MAMP and WATT are displayed before and not AFTER the readings!

Keeps a record of test results and you can name them which is useful.

Good app but??

Nice and great thing if you want to make play around with your wires and charger but do not expect it to be accurate.

Have tried using all fast chargers,car chargers and normal chargers and the results are a bit impressive apart from all fast chargers including both samsung and 40w iphone + usbc charger. I think ampere does not recognize fast charging and the highest result it can give is 980ma.

Overall pretty good app.

Hello. We made many updates to Amperes app. It now includes more functionality, better interface and other cool features. Please give it a try and if you will like it, let others know by updating your app's rating. Thank you! Regards, Andrew

Hello, Ching21

Thank you for your review.
I want to ask a few things: what is your iPhone model that you are using?
Also, what is the charge level at when you are measuring the quick charge?

On iPhones 8+ quick charge measured correctly when it’s measured from 1% up to about 50% charge, and when a quick charge enabled adapter like Apple 29w USB-C Adapter with Apple USB-C to Lightning cable is used.

Please let me know about your congratulation.
Regards,
Andrew

Rubbish…deleted app

Firstly it refused to do a test on ‘Compare Wiees or Chargers’ and the app reported it will only work if the phone is at 90% or lower, well it was at 71%.
Again the over power test wouldn’t work because it says the test would only work if the phone is at 75% or lower. Again it was at 72%.

It also reported when I finally managed to get it to test something, said the wattage was low at 4.2watt but it’s on a 96watt charger with a 100watt cable.
Useless, deleted the app and looking elsewhere. I suggest you do the same.

Developer Response ,

Thank you for your review. It looks like you are on IOS 17, where Apple made many changes to battery access. One of these changes - apps now can not know for sure what is the battery charge at.... Apple's iOS will return the same result for 72% and 71% and 70%, and even 69%... Add to this that it removed any direct access to any other battery info in iOS 10. We try to get information as precise as possible, even when we surrounded from all sides by Apple's limitations. For now, please try to test your phone when its discharged well below regular requirements of 70%, that was for non iOS 17 devices. Feel free to email me at support@criosoft.com if you need some more info. Regards, Andre
