Compact, informative and works well. I'd love to have a temperature chart option as well; should be trivial to overlay the existing voltage vs time chart. Another option to add would be SOC vs time instead of voltage vs time. It's not a linear relationship, but I assume the app somehow takes this fact into account when it calculates its displayed 'Remaining Capacity' value. These options would certainly justify a premium price! :-)

Good looking widget. For the interface, Better than 90% of battery widgets available here. I had used it on both RedMI Note 4 and Note 6 pro. Only problem is it gives wrong battery %age many times. Sometimes when you plug-in the charger, it does not even show phone is charging. You have to touch-open it once to start showing correct %age. I have excluded it from the power saver feature but it does not update. I have emailed then you screenshots of the app misbehaving

Hi, if the widget stops updating, means that the service in charge of the update has been killed. To prevent that, make sure the app if excluded form any power saving feature. To reactivate the service, simply open and close the app. You can find our email in the play store page of the app.

I like it, but for some reason in my Poco F4 5G , the widget sometimes seems on "updating". Tried to disabke auto-update but it still happens, so I guess it is not about software update. It happens once in awhile like once every 1-2 weeks. My only solution is to delete the widget and add it again, a little nuisance

Please make sure that the app is not power managed and can run in background. If it is "updating" opening the app should fix it.
