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! :-)

Update: I updated it and it still does it. I have to go through the consent stuff every time I open the app. It's happening when I click on the widget to check battery stats, if this helps. Edit: it is the privacy consent screen where I confirm what relative ads show up. Any time I click the widget to open the app, I have to go through it again. Using Samsung Galaxy S9+ with Nova launcher. Just sent an email to the info address. Thanks.

I'm trying to reproduce the issue but without success, can you maybe send me a screenshot of the screen that shows up?

A great widget until the last update. Now, every time you open it up to look at history, it asks you what personal data you're okay with them selling. Every. Single. Time. And it doesn't remember what you selected. They probably want to sell your data, and won't take no for an answer. EDIT TO ADD AFTER THEIR REPLY: You are asking every single time and do not keep our selections. That is, 100%, something YOU are doing, even if Google is the main one asking.

Hello Walter, we don't want you data... Google does. The new consent that we had to implement because of regulations and the fact that we have advertisement in our app is managed by Google. If you don't want any sort of tracking "Battery Ace PRO" is the app for you.
