App and widget updating vehicle status separately?

[trisk]

I recently updated the Tesla app on Android and the new home screen widget is a huge improvement, especially compared with trying to access the quick controls from the notification.

However, I notice that the widget seem to fetch updated vehicle information separately from the app. It frequently shows status information from different times. Example in the screenshots below (although the mileage is now consistent in the screenshots it said 150 miles in the app when I first opened it).

Also it's annoying from a battery life perspective for the widget to update the last updated timer on screen every second, since that prevents some power management optimisations.

There will be discrepancies between the widgets and the app and that is by design. When you start the app, it immediately starts waking the car up. The app shows what it knows while it waits. Once the car wakes up and information is returned, it will show "live" information from the car.
The widget should never wake the car up. If it did, the simple fact of using the widget would mean the car can never go to sleep. Because of that, you will get whatever information was available the last time the widget was able to get information. There are some API services that can be called without waking the car up. I'm guessing the widget uses those, or there is caching going on in the app. That part I'm not sure. In any case, if the car sleeps, it cannot provide live information.

The widget displaying the last snapshot of information polled by the app is the design I would've assumed, but it seemed like the state in shown in the app was behind the widget on occasions.

It would be, while it's trying to wake the car and receive information, as we see in your screenshot (seen a while ago, circle turning...)

My widget option seems to have disappeared. I uninstalled and reinstalled the app, and no longer show the app listed when I try to customize

Does anyone know for sure if the widget doesn't wake the car? Because the timer on my widget never seems to go past 1h, or even 30 minutes! I'm making sure not to interact with the widget or the app :/
