I was using this app on my M3 along with another iOS app Stats for Tesla. I’ve been using both apps about a month now and have been consistently losing about 20 miles of range each 24 hour period. I did an experiment whereby I changed my main Tesla password and reloaded each app individually. I discovered that Stats for Tesla did not contribute to vampire drain whatsoever. However, this app Tesla 4 U contributed significantly to vampire drain at the rate of anywhere from .66 to 1.2 miles per hour which is unacceptable. By the way, without this app polling my car I lost no range after 11 hours. Although this app has some nice features and it’s free, I can’t recommend due to the high vampire drain rates.
Developer Response
Try our new version with scheduled request. There is NO vampire drain
Just doesn't work..

Literally you cannot get information at allOnce you login it will log you out once a day and and tell you the token is invalid there's nowhere to really refresh the token which I'm not sure why any application you refresh a token every single day. (they're actually actually is no place to do that)All I can tell is don't waste your money.. this is a horrific execution of an application..
Very handy

I wanted two main things from this app and it delivered. Charging status and logs and driving efficiency logs. These both work very well!On peculiarity is that the "parked" event updated every 1.5 hours or so during the night. I'm not sure if it was caused by GPS drift, or something else waking it up and registering a new "parked" event. I haven't tested long enough to see if it contributes to vampire drain or not. But I don't see any controls for polling frequency as was suggested by the dev response to another review.Update: I just found the charts for driving and charging! So very cool!This was not immediately obvious so, Open an event, like driving. It will show a map. (cool, right?) Now expand the arrow at the bottom of the screen to see the details. Then swipe L/R to see the charts!
The app we’ve long waited for!!

Finally an app that tracks (and logs !) all stats such as speed, battery consumption, trip maps, etc. accurately. Kudos! Keep the updates coming. I’d definitely be willing to pay for this, too.
