Battery Charge Source Current

Thanks to the developers. After trying many similar apps, finally this one worked on my Oneplus One phone. The only con is that it shows negative figures while charging and vice versa during discharge ..hence one star less on my rating. Ignoring that, the app is great for testing the live charging rates of any android power source. Now I know exactly which all alternate cables can be used and which ones to avoid, while charging my phone in a hurry.

With my phone attached to the charger but the charger not plugged into the car I can see the discharge rate, ie -450 MAH. Then plugging into the 12v outlet, I can see the nat charging amperage, ie 550 MAH. This means the charger is charging at a 1A rate. Great to compare the actual charging rate of an individual charger and see if they are operating as advertised.

Samsung victory. Only showed one screen whether plugged in or not that said unknown source and zero amps.

Installed it on my Droid Razr Maxx HD. When charging it would show unknown source with a rate of -367000 mA. Seriously? That's 367 amps of current flow. I should be dead just from holding my phone. With no charger connected, it shows current flow of 15000 to 20000 mA. That's a drain of 20 amps. My phone has a 3300 mAH battery. At 20 amps, my phone would have a maximum battery life of 10 minutes.

I can't blame it for not working properly on my OnePlus One, but it did work a lot, enough to tell me that one cable wasn't charging as fast as another, so kudos! I still feel the ui could be better.

Thanks!! It is also quite accurate :-)! eg. 469 mA on a 500mA USB battery pack type charging device! Newer apps, don't recognize any charging info & this one did, worth up $10.00 :-p, saves time & find dirty/broken home/car chargers & info on my s2 !! I depend on my s2 for hotspot & data intense tasks, I use a Note 2 & s4 as well, I might try this on my newer phones if I can free up some apps/space on those :-p. I like to stick to having same app on all devices, easier + cheaper/cost effective too! Thx!

Love this simple app with no nags. Worked great on my Samsung Galaxy note (very important to know you have high current charger on that power hog) but now with nexus 5 is reporting bogus values. Sure it will be fixed soon :-)

Did nothing but waste time.

This did what I needed it to. I just bought a charger off of Amazon and was afraid it was a fake. This app disproved my fears and the charger is delivering a constant voltage similar than the stock charger. Thanks!

Apparently accurate tested it out with a 500Mah charger and it read 490-515mah used it with the supplied charger and it read it well also... I will use this with the new Solar phone charger (no battery to regulate power) to find out just how well it works.. THANKS.. (Samsung Note 4)

Helps me throw out a bunch of old cables not capable of delivering high current

Unknown power source, positive and negative mili ampere amounts when ac connected.

Love this app. Shows how many mA is charging my phone but not the source of power. Still great app and very useful for me.

Was working fine some time ago on Samsung, but when plugged in my LG is showing different numbers including below 0 and when cable unplugged stull showing being charged with random values.

The first time I ran the app it crashed my phone. After a reboot if I plug in it says unknown 1200ma. If I unplug it says 450ma. So I don't know about that. But I just ran another app that also said 1200ma but when I unplug it goes to 0.

No frills here. Just a quick app to show your charging wattage from then source. If you think your battery is charging slowly this can help you determine the difference between an aftermarket charger and the OEM charger that came with your device. USB cables matter as well.

Was working before android 6.0.1 update, but after update my Samsung Note 4 randomly started rebooting. I had to factory reset and still the issues continued until I uninstalled this app. NOT FOR Marshmello 6.0.1

Accurately reports charging current and does not require any permissions. The artistic nature of the interface could be greatly improved, though.

Worked fine on my note3

Using on HTC One X. On start up the app crashes therefore unable to use.

On my Nexus 5, this app reports a rapidly changing large negative number for the charging current.

For NEXUS 7 2012 Lollipop Great... Shows net current...(charging current - usage current)

Worked with my Galaxy S2X but didn't with my old Nexus 4 and didn't with me Nexus 5 =(

Apparently accurate tested it out with a 500Mah charger and it read 490-515mah used it with the supplied charger and it read it well also... I will use this with the new Solar phone charger (no battery to regulate power) to find out just how well it works.. THANKS.. (Samsung Note 4)

Still works great on most of my Samsung devices, but in Sony Xperia z2 it shows some funny numbers, it has the potential to support more devices, with some math corrections.

Two higher rated apps failed to distinguish different current levels - this worked straight away.

On my Nexus 5, this app reports a rapidly changing large negative number for the charging current.

Lets you check which charger supplies more power than the other. Ditto for cables.

****UPDATE: I'm not sure if this is working on my Nexus 7 2013 running 4.4.4. I shows a negative voltage reading when charging or discharging. **** This has been the best/only free app for finding out how many milli-amps my phone is getting out of each of my chargers. It's kind of ugly but I don't really care. Thanks for a functional app with no ads. Great work.

Doesn't work on nexus 5, shows -100k-400k mA

The first time I ran the app it crashed my phone. After a reboot if I plug in it says unknown 1200ma. If I unplug it says 450ma. So I don't know about that. But I just ran another app that also said 1200ma but when I unplug it goes to 0.

Did not work on my Galaxy S III

Small ram size yet tells me what my charger and cable are outputting. Cheesey looking logo.

Not much else to say. This doesn't work. Move on.

Works fine on all of my phones and my galaxy tablet. If you've bought cheap chargers or "oem" chargers from Amazon or eBay then this is a great little app to have so you'll know if your new charger is good for your phone. It's very basic, it shows you the amps if it's charging, and it has no permissions. I'm so glad I was able to get this info so easily.

Doesn't work at all on my GS3 with android 4.4.2

"Unknown charging source"

Tried on nexus7 and nexus5

It says ac fast charge.. ac fast charge.. 5vdc detected on pins 1 and 4 pins 2 and 3 bridged. Does that mean my microusb pins have a solder bridge that I need to get removed as my s2 is charging for 4 to 5 hrs?
