Welcome and congratulations on your new MY! It’s understandable to put your vehicle in the “miles range” display mode at first. After a short while, most owners switch over to “percent battery” display, which provides an energy available estimate similar to ICE cars. You will then find yourself not worrying about a few miles lost here and there.
Battery drain and phantom drain are discussed at length on numerous threads here. Sentry mode will keep the vehicle awake and thus cause battery drain. Check to see if Sentry mode is enabled for your home and work locations, and decide if you want or need Sentry mode in those places. (You can always override these settings temporarily by tapping the sentry icon on the top right of your home screen... or switch it on and off from the Tesla app.)
* Note: Frequently accessing your Tesla app will keep your car awake and cause phantom battery drain.
Personally, I use TeslaFi which is a subscription service to record and document almost all data from my Tesla. I love it. It shows all energy used, all charges, stats for drives, cost for charging at different locations, etc. so you have a complete log book on your vehicle history.
You can designate destinations as ”Tagged Locations” which makes for an easy travel log / total miles driven for business tax purposes, etc.
More importantly, TeslaFi shows when you car is sleeping. For some strange reason after a software update, my car was experiencing high phantom drain. Going to TeslaFi, I found that my car was not sleeping and made a few adjustments in the sleep settings.
TeslaFi is free for a trial period.
Should you opt to try TeslaFi, my referral code is “TeslaFiCodeRS” It is not a big deal, nor the purpose of my post, but it is appreciated should you find this helpful.
Enjoy your new MY!
