CurrentWidget: Battery Monitor

CurrentWidget displays how much electric current the device is using from the battery or receiving from the charger. It can also notify you when the device is using too much battery.
*NOTE: The electric current reading doesn't work on all devices. The reason is that the manufactures (mostly Motorola and Samsung) don't support this in the battery driver or in the hardware.


* Add widget to home screen after installation.

Now also includes:
- Two widget designs (as two widgets in the widgets list)
- Classic and Text.
- Notification
- get real time alerts on high current values!
- Transparent style with customization options
- Android Backup Service
- Automatically restores your settings on new installations
- Voltage & Battery level (%) display
- Log battery values
- Plot current graph
- Analyze log options
- Log file rotation
- Custom operation
- set an arithmetic operation on the current value to adjust for different devices
- Option to show a persistent notification with all information from widget.
- Customizations (size, color, etc.).
- DashClock Widget extension.

Touch the displayed value to switch views.Select only one view to bring back configuration shortcut.Open settings & graph via launcher icon.


* The lightning icon changes color when the phone is charging (white/green).

I like the small size program, does the job nicely, but pixel for some reason does not read the current at all, the whole reason for me to download the app! Oh well....

It was best until it lasted. It worked till Android 8.1. Upgraded to 9.0. Doesn't work now.

The only app that I'm using till now from the last 7 years.. Amazing app, accurate and precise. Must have on your phone.

Great app A little suggestion it would be great if could plot trends of other values that I get in the log for instance voltage and battery level

Best widget available if you are running Android 8.1 or lower. Does not display current in Android 9.

Pra. B. Jan 11, 2019     

this is not working with Samsung note 9, mainly the current value, it is showing zero all the time

Does not work on my Samsung Galaxy Tab S 10.5 (SM T-800), Running LineageOS 14.1. The app installed, but could not place widget on screen.

Way too small as a widget, BUT there's a text widget which works great.

Installed this app and tried to add Widget on My Moto E4. Now my touch screen stopped working. (Sigh)

Rom. Y. Aug 20, 2019     

pretty useless since it doesnt show a "minus" in front of mA value when device is not charging

Ra. D. Oct 25, 2018     

love it, maybe add battery level / full notification?

Does not work on Samsung note 9

Doesnt show option to stop charging I hate it

This widget worked brilliantly on all my Samsung phones and even my Huawei Ascend Y600 but unfortunately it's not working at all on my Samsung Galaxy Tab 4 8" (SM-T330) running Kit Kat (4.4.2)

Downloads but hangs on install every time. If I kill Play Store it says it "successfully updated Current Widget" but it's not in my widget list or app drawer. Nexus 5. Edit: Rmdroider happily tried helping me in getting this installed and all is well. Great support and the app works nicely.

Helped me find out why my phone took too long to charge. (I was using the wrong charger which was just an USB2.0 one which delivered 4 times less current that what should be delivered). I also like the 'Top processes' feature which displays a list of processes ordered based on their average current consumption. This is much more detailed than the battery consumption graph that comes built into android.

I've loved this app, and used it on most of my phones for a great indication of how fast my battery is draining or charging. Sadly, as I just switched to a Note 4, I must regretfully leave this behind as Samsung does not provide a way for this app to read what it needs. I can't take away stars for the app not doing what it cannot (and clearly warns me about), though, so I'll rate it based on recent past experience with it instead.

Great but inconsistant interval update. Even after i set the interval, on my phone, it didnt refresh at my interval setting, very inconsistant and i have to tap update for immediate reading. But works on my tablet (though ampere reading not working maybe due to the tab not supporting it) Super useful for charging rate check and voltage to compare with battery charge percentage

Jan. P. Aug 10, 2014     

Thanks to CurrentWidget I was able to identify low-mA (slow-charging) chargers and cables. The real-measured differences were up to 3x in my case across 1A-2.1A chargers. Feature request: It would be awesome if the app could use the battery % full information and current intake power and estimate+visualize the time needed to get to a fully charged status.

Bra. M. Oct 27, 2016     

Used on Xperia M to check when charger connected properly (bad USB port) and it worked great. Tried with Xperia Z and widget won't refresh unless I hit the button. I already set integral to one second but no good...

Dav. S. Dec 20, 2014     

I nearly dumped it as useless, because the reading did not change sign when going from discharging to charging. Then I discovered it changes the colour of the lightning icon instead - not what an engineer like me would expect. Now I know that I'm happy, and can find the optimum position on my various wireless chargers. I am marking it down one star because of that. Even changing the colour of the numbers would be better; Red for discharging and green for charging. Nexus 4, Kit Kat.

Ste. R. Mar 27, 2014     

Great idea, I would like a widget for current charge rate, but on my Note 2 this just shows 0 unplugged and 1mah when charging. On my sons Amicroe cheap tablet it shows 443 no matter what is actually happening.

Ami. B. May 1, 2014     

The mA value displayed by this app is meaningless, it displays the reference value not the actual charging value. Imagine your car speedometer would always display the maximum speed your car can travel at, but not the actual speed right now. How useless! The app displays the charging amps as 1698mA, but thats the reference charging value, not the actual. For days I've been trying to debug a battery charging problem using this app, and was totally misled by this number that it kept displaying. This made me believe that my stock charger (2A output) was working as expected, so I was trying to figure out a problem with my phone instead. I finally got suspicious when I connected a 700mA charger to my phone and this app still reported charging current of 1698. Finally I got my hands on another app "Galaxy charging current" which is perhaps showing accurate data.

While the author says in his description that the widget doesn't work with Motorola and Samsung, yet according to the Google Play store it is compatible with my device. I installed it, and it shows, always, 1 mA charging, or 0 mA discharging. Great idea, but it's not compatible with my phone (Samsung Note 3) so please update your information/programming so it doesn't show up as being compatible with my phone. 1 Star for the idea, which is good, + 1 Star as the minimum you can get = 2 stars. Thx.
