Frequently asked questions
I just charged the car, but the infomation does not show up in the bar chart. Why?
-
Your iPhone is never put in Low Power Mode (it prevents the app from collecting data)
-
Your settings are as shown below:


-
If you are leaving your car plugged in for more than six hours after the charge is complete, the car may start a top-off charge. Doing so, will overwrite the data for the previous charging session. To avoid this overwrite, please unplug the car prior to the six hour time window after the charge complete. You can set the start time of the charge (in the car) to start a little later so that charging finishes less than six hours before you get a chance to unplug the car.
-
The charging info shows up in the graph only after you disconnect the car from the charger
-
If you have just unplugged the car and the charging info does not appear in the bar-chart, please do a pull-to-refresh on the charts screen
-
Another common reason for charging information not appearing on the bar-chart is that while attempting to remove the charging wand, you might have inavertently started a new charging session by moving the wand back and forth. Doing so causes the charging information to be overwritten with zeros (see the screenshot below). To avoid this, make sure that the car is unlocked prior to removing the wand and then remove it without moving it back and forth. Specifically do this when you unplug the car: -
Unlock the car using Stats -
Press and hold the button on the wand and wait for the LED color to change and only then pull out the wand with one smooth motion.

My average efficiency and phantom drain rate do not show up as vertical lines in the histogram of efficiency and phantom drain rate across all users. Why?
The Siri Shortcuts that I've added previously do not work anymore.
I just left the door open to test the "open door" notification, but did not receive any notification from the app. Same question about the charge reminder notification. Why?
The app says it cannot connect to Tesla servers. How do I fix this?
Why doesn't my phantom drain rate show as a vertical dashed line on the phantom drain rate distribution
The vertical dashed line which represents your average phantom drain rate will show up automatically once the app has collected at least ten datapoints for phantom drain.
Tesla is an electric car. What does the MPG in settings tab mean and why do I need to enter this number?
The MPG value and "price of gas" that you enter in the settings tab of app are used only to compute the "cost savings" (in the first bar-chart on second tab of the app).
Specifically, the app computes the savings associated with each charging session. the saving is the difference between the cost of adding equivalent estimated range to your Tesla and to a gas car whose MPG you specify in the settings tab.
iOS is showing me a message indicating that Stats has used my location in the background. Why does the app need my location?
My historical data has disappeared. What can I do to restore the data?
-
Triple-tap (i.e., tap three times) on the first screen of the app. This should initiate data recovery. Let the app run on the screen for ~3 minutes. Do not navigate to another screen.
-
Wait for a couple of minutes and then go to the second tab of the app and pull down to refresh.
Watch app and its complications do not work anymore. What can I do?
The watch app does not install. What can I do?
The watch app installs, but it keeps asking to "Launch the iPhone app first" and the message does not go away after launching the iPhone app. Help?
-
Restart the iPhone
-
Delete the app from iPhone
-
Install the app from the App Store
-
Launch the app on iPhone and wait for it to connect to the car
-
Wait for the app icon to show up on the watch and then tap on it to launch the app on the watch
-
If the watch says “Launch the app on iPhone…”, remove the iPhone app from background and re-launch it.
-
Wait for the watch to connect to the car and you see the name of your car and range and SoC
-
Add complications (optional)
Watch app crashes or I get the "Please Launch..." on the screen and it does not go away.
-
Delete the watch app
-
Reboot the watch
-
Install the watch app
-
While the “Please launch the iPhone app…” message is showing on the watch, force-quit the Stats app on iPhone and re-launch it.
Is there a tutorial for this app?

What do "efficiency", "estimated range" and "rated range" mean?
Does the app need to be running in the background for it to operate correctly?
Why is the efficiency on the first screen of the app sometimes different from the efficiency shown in the second screen of the app in the graph?
The efficiency shown in the first screen of the app is measured over ~10 miles. The efficiency shown in the third screen of the app (graph with orange dots) are measured over 50/200/500 miles
Why does the app need the "Always" permission for location tracking? Is the app tracking my location constantly?
I just manually calculated the cost of charging and it's lower than the cost that the app has calculated. Why?
The app takes into acocunt the charger efficiency (~85%). So, in order to add X kWh of energy to the car, you need to pull X/charger_efficiency from the wall.
I can't see the old widget (the one with control buttons). What happened?
