Amperes 4 battery charge info Reviews

Amperes4batterychargeinfo just sits there in a loop just testing and testing and testing it takes forever and then doesn't do anything.

There's no progress indicator and no way of knowing how long it's going to take or if anything is actually happening at all which it turns out nothing is.

A worthless garbage app that's not worth the bits of storage that it takes up. Amperes4batterychargeinfo is literally does nothing but show you an animated battery.

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 Amperes4batterychargeinfo 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

The first thing I saw after I bought Amperes4batterychargeinfo:

“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 Amperes4batterychargeinfo , not after?

I bought this because I thought the tests would show the charging wattage just like the free version of Ampere does. However it only shows the result in mA. Which is disappointing because I'm using it to evaluate two wireless chargers that were sold based one their wattage output.. I don't know why the free version would have that and not the paid.

Additionally, the "export results" button doesn't work at all on my iPhone XS.

I have found Amperes4batterychargeinfo 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.

Turned on to be very useful app for me. I have several old smartphones, and what I did with the help of Amperes4batterychargeinfo - I rechecked the health and charging capability of each battery to know which one is worth it's recovery.

It does have a handful options for the user to configure for their own needs. I don’t think it’s super accurate but seems to be able to give you a reasonable idea.

I have one confusion though: what is the difference between “Amperes” and “Amperes 3”? I purchased two apps already but it seems the new one does the same thing as this one but I cannot find any upgrade options…

I wanted to see how some stats on my MagSafe battery pack, but Amperes4batterychargeinfo couldn’t detect that my phone was being charged. I tried changing the test configs to indicate it’s a wireless charger, but it still didn’t work. But does a good job with wired chargers. Overall good product, but wish it would work with wireless chargers too. Still, good stuff Andrew, keep up the good work.

I’ve been using Amperes for nearly 2 years and can confidently say it’s the best solution for testing & comparing chargers I’ve come across!
My only “complaint“ is there’s currently no option to save charger/wire names and therefore have to be re-entered on subsequent tests after quitting Amperes4batterychargeinfo . It’s not the end of the world but certainly makes testing the same equipment more cumbersome.

Amperes4batterychargeinfo is good cause it allows me to see some info about my battery charge and it's really useful when u wonder why your battery charge is going down so fast. By the way you can test your battery so then you'll get exact results

Does exactly what I wanted. Checks the charging speed of my devices to compare and know which cables and plugs are best. (Anker of course) Got a free app but it didn’t work. So paid the 2 bucks and worked right away with some other cool extras.

It really helps me to get out of many problems! None of services provides me with the information as much as it does. Thanks to that app, I can measure the battery life duration and see whether it goes wrong and needs to get changed (a widespread IPhone problem).

Great app and use it for testing and reports. BUT ... the new layouts are terrible. I could see everything on one layout but now I have to pick an icon to view the data in a font that is 10 times too big. Bring back the more functional layout...

I got a new iPhone 15, and am using Amperes4batterychargeinfo 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 Amperes4batterychargeinfo 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. Amperes4batterychargeinfo 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!

Edit: all issues were addressed.

Please add a conformation step before clearing results data. Very easy to accidentally delete all one's measurements otherwise. Also being able to edit the test configuration info after a test is run would be very helpful. Also where test results are displayed (at least on an iPhone X) the fields with the Name and Charge get cut off with no way to later see what was typed originally. Finally, there should be a note to users that the charging rate, or score, varies greatly with how full the battery is. Perhaps recommending all tests be done under 50% would be better than the 90% required now.

Thank You Andrew, Amperes4batterychargeinfo is perfect for my needs. I have the new iPhone Xs Max with fast charge capability. I purchased several adapters, (usb-c & usb-a) & wireless in both formats. I’m testing various cables by different manufacturers. With your app I am able to test all combinations so I can use the accessories with the best results! Also the ability to label the tests helps me keep my results organized! Great app! Keep up the good work!

I wish this could run in the background while you were still using the phone instead of having to leave Amperes4batterychargeinfo open. It would be nice to be able to surf the Internet, text when needed, and check email etc. etc. Now anytime I get a phone call it resets the test. Kind of defeats the purpose...

At least this is the best battery charging info app that I have found. The programmer of this application constantly updates his product, and each version is greatly improved over the last version. If you wish to see what combination of charge and lightning connector works best, I believe Amperes4batterychargeinfo is the one you are looking for. It was worth the $2.00 I spent quite a while ago, and Amperes4batterychargeinfo is much improved.

What an outstanding app. I have multiple cables and charging devices and this let me determine which configurations were best and just as importantly, which were worst at charging my iPad Pro.

Since I travel a lot I was pleasantly surprised to determine a thin cable charged just as quickly as a thick, bulky cable. On the other hand, I was disappointed to find out my Qualcomm 3.0 Quick Charger didn’t charge as fast as my NewerTech NuPower 60W adapter (fortunately the NuPower has 2 outputs so I can charge both my MacBook and iPad at the same time)

I’ve played with Amperes4batterychargeinfo for a week now on different chargers. On wireless I’ve repositioned the phone in relation to the pad and have monitored the application.
Amperes4batterychargeinfo just doesn’t work. Readings will sometimes fluctuate greatly even when the phone is stationary and hasn’t been moved.
I cannot recommend. Save your money.
