3C Battery Monitor Widget

I've been using this program from 7 to 10 years.... All of the sudden, out of the blue the app will not load or save files to anywhere on the phone or the SD card. I haven't change configuration in a long time but I tried today and it won't allow it so I don't know when this happened.... So this was a five-star best battery manager I've hand for over the last 10 years... And now if I can't save and load configurations it's kind of useless....

Widget not updating. Nothing else matters. I don't stare at statistics every minute. Just want to see ... that's widgets are for, come on! After Android 12 update, almost nothing works anymore. Looks like an abandoned project.

On my device the calibration log gets filled up with junk: percentage changes of like 3-5% and really bad mAh estimations. Usually happens at fast/supercharging. Sometimes with values of 900mAh, or 6800mAh. (Battery is 4.4Ah stock) Pls filter this false data out

I really like the app but noticed the pro version I purchased is no longer. Looks like you have to start off from scratch and purchase each component which I'm not happy with. Again it is a really good app but I feel since I already purchased the pro version a long time ago, now I have to buy each feature individually. Not happy with that.

Great app, highly technical and customisable.. only problem is I am unable to keep it running in the background. Android keeps killing it despite all my efforts.

Great app, only 2 real complaints are the min/max graphic legend on the widget is super tiny and almost impossible to read, and the app no longer has a battery health indicator on the status screen. Even after changing the text size in the app and on my phone the min/max graphic legend doesn't change size. The absolute value legend tex changes size beautifully when I change the text size setting, but the min/max values stay their impossible to read size.

I have never been more impressed by an app much less a system tool. I downloaded and skimmed the app a few days ago. Saw potential, but wanted to give it a few days to accumulate data. I just clicked evey button and am floored. I was sold before i saw the change log. But a $5-10 system tool that doesn't have holes to fill by another app, and will probably maintain (or improve) usefulness indefinitely has more value than my experience can estimate. I have never paid money through the app store or

No partial clearing of history. latest version no good . i have to revert to the older version. Very difficult to locate last unplugged. Unfortunately auto-updated leaving me no choce but to delete.missing history data ever so frequent

After owning the paid version for so long, this is worth more than I paid for. The Dev has been relentless in issuing updates. Thank you. I may not understand every thing that I see in this app but the feature that I like the most is the customizable line indicator. This is the one I can't do without.

Had bought pro version YEARS ago, and it was great. Over the years many issues started to come up, minor things mainly related to Android updates that took a long time to get fixed. Now I'm just uninstalling and probably for good. The change to the key apk is just the last straw.

I used to have the pro version and loved it. Got some cryptic message that it was going away - tried to follow instructions but lost everything. So now back to the free version. I suspect this might be a way to force a bunch of sales or something. Bummer...

It always claims the current when charging to be 1500mA, despite me seeing different charging speeds when using different chargers and cables (my calculations arrive at values between 0.6 and 1.8 amps with my chargers). I'm left thinking that the values for current shown are unreliable and inaccurate.

It's working perfect for measuring battery performance, but there is a bug with the latest update that prevents you from exporting data. It will say "Operation failed."

I don't need any of the pro features, but anyway I bought it just because it helped me to prove that the new battery I got from a repair service was faulty! The history showed that wrong temperatures were recorded starting from the time I got the new battery. As a result, I easily got a replacement today from the shop.

Reported twice as much current other apps. And didn't have notification of current and voltage and temperature. I prefer the notification panel. Plus I found another application with alarms for charging limit and minimum limit plus the temperature maximum and minimum limit. Called battery Guru. Not false review. You don't have temperature and charging alarms. Not advertising. I simply tried another app and liked it better.

Have been use the app long time ago. It's work very good for fast charging and quick charging type phone battery. Change my phone to VOOC charging type it's doesn't work accurate or I missed the way for setting it up.

Great for showing the rate of charge in mA to see if a charger and cable are really fast charging or not. Also good to check the battery temps when charging, as too much heat will cut down on the battery life. Able to take stats every 5 mins and doesn't drain the battery :-)

Tells you critical battery information, which helps you to be able to make YOUR OWN decision on the state of your battery life and or capacity, which is not always accurate information provided by the device. BEEN USING THE APPLICATION FOR SEVERAL YEARS NOW, AND I HAVE A GREAT DEAL OF UNDERSTANDING WHEN TIME IS TO RECHARGE OR REPLACE THE CURRENT BATTERY....ALSO SINCE BATTERIES ARE BUILT-IN, I CAN SEE THAT IT MAY BE TIME TO GET AN EXTERNAL POWER SOURCE, SUCH AS A POWER BANK OR EXTERNAL POWER CASE...

Your stupid pop up ad to advertize the pro version happened while I was driving and navigating and I had to touch my screen several times to remove the ad and go back to navigating!! Bad form!

I really appreciate your app that's very technology

Bad screenings data. There isn't any selection to report "since full charged", or "since last charged". Also when you suddenly touch on measured numbers, they suddenly changed.

After recent updates in June the widget stops refreshing. I have checked all settings and have no power optimization for 3C apps, so it is definitely serious bug.

Suddenly the text in the widget is very small and can't be changed without paying. Looking for a new battery widget.

Best one I've tried. Bought pro. If notification package doesn't survive reboot, click the wrench icon next to it in settings.

Have used for years. Seems to have a sign problem on pixel 3 - says charging when unplugged, discharging when plugged in!

It usually shows zero. Always says charging/disconnected! It just does not work. UNINSTALLING!
