OPO Charging Current

I have a voltage meter/ current meter. And I have used the app to see its credibility and sometimes when one plus one is pulling full 12.5 watts of power it still shows 800-900. Instead of showing 1800-1900. But easy fix is to plug it in again and it shows the right value. With screen on the phone only pulls 7.9 watts and the all is very close in this test and does show the current being pulled as 700-800. The main reason for this app is to use it with car charger.

Works well on regular charge up to 5V/1.7A. However, it gives negative readings on fast-charge (12V/?) for Asus Zenphone 2: reading is around -1000mA. Normal charging gives normal/positive data. In other situations it reads like 8000mA for short periods. However, it is still useful.

App is fast and responsive and light, accurate. Much better than slow and fancy Ampere app. This app is working for my opo as well as other phones. I think the developer should make it a generic app not brand specific it works flawlessly.

I was about to switch to another app when I clicked on "About" and noticed the note about expected charging values to differ under certain circumstances, i.e. screen on/off. I was able to confirm the increased charging with the screen off thanks to the new scrolling graph feature. What a nice touch! I really enjoy the instant charge readings I get from this app, whereas others seem to take their time. My only complaint- use of the word "reference" where "present current" or "current now" would work.

Hey developer thanks for this wonderful app i am using this app for more than a year this app would be best if you also add Battery Temperature reading in it. Kindly plz do take notice of this important so that this app wud become a complete app of its kind

Useless app.. Even though my phone is charging.. the graph is flat showing discharging and raw info is blank

Unfortunately it is not able to access the voltage and current info on Nokia 6 (fw: 7.1.2), othervice the app runs OK and looks nice.

not sexy but it definitely does the job. very handy to test your power usb cable or your car adapter.

Very nice app, Simple. Please adding more features like display average current charging on notification drawer when charging and battery temperature Dev :) I like it

Simple and easy to use. Before installing this app it never occurred to me how much difference a cable can do to phone's charge rate. Very useful app.

Stopped working after updated to Nougat

1+3T dash charges at 4 amps.. only says that it is charging at one!

Not working in mi max2 on android 7 nougat

The only app showing accurate value even for flagship samsung smartphones

Worked excellent on my Samsung phone, dosnt work on moto g5

the best there is ! the only one I RECOMMEND !

Dose exactly what it says

Real time mAh view ...just awesome.

Great app does the job

Great work. Works nicely.

Best current app

Great

good

Was experimenting with my phone with some non standard ways to charge the phone, this app came in super duper handy very useful app to check chargers capacity and capabilities...

After reinstalling it works properly! op3

Thanks for getting back to me Dev. Looks like permissions are fixed and I am glad to keep using this very straightforward app. It has been quite handy occasionally and I like that it's written for OPO because I would think it's more accurate calibrating for one device.

Excellent work by developers ..

Absolutely helpful

Nice App

New update wants sketchy access to pictures, videos, and other things that a charge current app DOES NOT NEED.

Helped me identify a faulty cable.

Gives me accurate info on how fast my phone is charging and how well my charger is functioning

Very useful app to check charger/ cable quality.

Works well

Wow! I have downloaded this app long back. I bought my phone from US. To use the charger in India I had a use a small plug converter which is of worst quality. Due to that my phone is taking 3hrs to charge while normally it takes 2hrs. I came to know about this after installing this app. Thanks a lot dev!

Light and nice. It has a problem with unit multiplier on Nexus5

The title says it all. Too easy to use. If u want to see the full charging current. U need to open the apps and turn off ur screen for a few sec. Turn it back on u will see the current goes up to 1.8A and above (if u use a good cable and adapter)

I'm using it on my Oneplus X, where the shown values seem to be multiplied by the factor 1000. I reckon the values extracted from the phone are already in mA (in A on the OPO maybe?). It might be easy enough to simply check the phone type and adjust the divider accordingly to show the correct data. Says I who doesn't do programming ;) . Anyway, thanks for this little tool.

Showing only 300ma in my opo with stock charger and cable anyone wid same issue
