Tesla recently completely redesigned their iPhone and Android apps. Just a couple weeks after releasing version 4.0, Tesla released an update that included new features such as the ability to change scheduled charging, adjust your charge departure time and more.
Most of these features require your Tesla to have update 2021.36 or later. At the time the app was released, 2021.36 had yet to be available. Software update 2021.36 has now started rolling out to individuals and we now have our first look at the new features in the Tesla app.
Scheduled Charging
The ability to charge your car at a given time, or to have it charged by a certain time has been available in the car for a while now, but we'll now have the ability to schedule it directly from the app.
There's a new Schedule category that will allow you to adjust departure time and scheduled time charging.
Once you tap into the Schedule category, you'll be able to pick whether you want departure time charging, or scheduled time charging.
Tesla's wording here hasn't always been clear, but departure charging lets your car pick when to start charging, and you just let it know when you want it to be completed. This has the added benefit that your battery will be warmer when you're ready to leave. It's especially useful in winter climates.
Scheduled charging is essentially the opposite of departure charging. You pick the time you'd like your vehicle to start charging and it'll continue charging until it reaches your set charge level, such as 80%.
It's interesting that Tesla puts charging options under a ‘Schedule' category instead of ‘Charging'. It leaves the door open for other scheduling options. The obvious one is the ability to schedule your climate in the car, but there could be others such as the ability to schedule Sentry Mode.
I'd personally love for Tesla to include a Nest-like scheduling option that would let you pick the days of the week and temperature when you'd like your climate turned on.
Bioweapon Defense Mode
If your car is equipped with Bioweapon Defense Mode, you'll now be able to turn it on directly in the app. You'll slide up a drawer in the Climate section of the app which will give you the ability to turn on Defrost or Bioweapon Defense Mode.
Adjust Charge Amps
The last improvement that comes to the app with update 2021.36 is the ability to change your charging amps while the vehicle is charging. A new button appears underneath the charge limit slider that will let you select the amps used.
The 4.0 release of the Tesla app had a similar feature set to the previous app it replaced, but it looks like Tesla has plans to continue adding new features now.
In software development there's often an MVP (Minimum viable product) that the product team is willing to release with. In this case the MVP appears to have been the features that were available in the previous app. Now that Tesla has released the new app they can focus on adding new features that they may not have had time prior to release.

Last night on X, Elon Musk confirmed that Tesla will be expanding the service area for its Robotaxi Network pilot in Austin, Texas, this coming weekend. This is the first official confirmation we’ve had of a date for expansion, following news that Tesla is hiring more Vehicle Operators and plans to expand the Robotaxi supervisor ratio in the coming months.
This is a sign of Tesla’s confidence in the Robotaxi pilot program and its current FSD builds.
Expanding to a larger service area in Austin this weekend
The announcement confirms the sights we’ve been seeing of Tesla’s engineering validation vehicles focusing on areas outside the initial geofence. This public test shows that Tesla was likely finalizing FSD builds and gathering the necessary safety data to push the boundaries for the service, and this upcoming weekend’s expansion will be the first direct result of that work.
Given the increase in service zone size, this expansion will also likely include the addition of more vehicles to the initial Robotaxi fleet of approximately 20 vehicles. We expect the new number to be anywhere from 30-50 vehicles serving both the original and new areas, combined, based on Tesla’s previously expected rollout schedule.
What to Expect
While the exact new boundaries haven’t been released, it is almost certain that the expansion will include the South Congress Bridge and the downtown core areas of Austin. Expanding into a dense urban zone will include more complex intersections, heavy pedestrian traffic, and a unique road layout. That is a major vote of confidence for Robotaxi FSD’s capabilities.
The expansion will also help Tesla to close the service area gap with Waymo, its primary autonomous competitor in the city. This quick expansion is a sign of just how scalable Tesla’s vision-only approach is, versus Waymo’s arduous and drawn-out mapping processes.
We also expect that with this first service zone expansion, Tesla will continue to invite more people to its Robotaxi Network in the coming weeks. Tesla has already sent out various rounds of events, as they’ll need users to continue using the system. If you’re waiting for an invite, it may be time to start getting excited about the next rollout.
We’ve been hearing about Grok, xAI’s AI assistant, coming to Teslas for almost two years now, but this is finally coming to fruition soon. XAI unveiled Grok 4 last night, but the entire stream didn’t mention Teslas. However, Musk later posted on X that Grok will arrive in Tesla vehicles “by next week.”
Between leaks and the Grok mobile app, there’s a lot we already know about Grok, but there are a few missing pieces that will be cleared when it finally arrives.
Next Week, or Next Next Week?
Musk said that Grok would arrive by next week, meaning it could arrive before then. However, based on how Musk typically states Tesla timelines, there are a few things to consider that give us a better idea of what to expect.
First, whenever Musk posts a Tesla timeline on X, he typically means when it’ll be released to employees and not a public release. Expect this to be the same thing.
Tesla releases software updates to employees first for a final round of testing before starting a gradual release to the public. Sometimes issues are found, especially with FSD updates, and the update needs some fixes before being released publicly. So expect employees to get it by next week, and not necessarily normal Tesla owners.
The second part to this is that Tesla always rolls out their updates gradually, so when it does finally arrive, it’ll only be available on a small percentage of vehicles. Tesla will gradually monitor issues and logs, continuing the rollout as long as no major issues are found.
Which Software Update?
The entire Grok UI was already included in software update 2025.20, but it’s not exposed to users. Typically, a new feature like Grok requires a vehicle update to be added; however, this version may be different, as it’s locked behind a server-side configuration.
Tesla likely has the ability to enable it for all supported vehicles with a simple switch. However, we feel more confident in it being rolled out in Tesla’s next major update, which is likely to be 2025.24 or 2025.26. Rolling it out in a new update aligns with how Tesla has historically introduced features.
If they turned it on for everyone at the same time, they could be exposing everyone to potential new issues, rather than only a smaller segment of users. While Grok is now well-tested through X and the Grok app, there are several elements that are new in Teslas, likely including the ability to control various vehicle functions, such as opening the glove box or other capabilities that voice commands are currently capable of. The Grok interface in the vehicle is also entirely new and may have some bugs associated with it that will need to be addressed, especially if they impact other features.
What we can likely expect is that Tesla will make some tweaks or bug fixes to Grok with the next major update that weren’t included in update 2025.20 and they’ll begin rolling it out to employees and then customers.
Supported Vehicles
Speaking of supported vehicles, thanks to the behind-the-scenes look at Grok, we have a good idea of the vehicles that will be supported. Tesla uses the same code for most of its vehicles, but then it’s compiled for each type of hardware. However, only the needed code is compiled for each vehicle, meaning that some pieces are left out entirely. Unfortunately, Grok code is not included in Intel software builds, meaning that only AMD Ryzen-based vehicles will receive Grok, at least initially.
We’ve seen Tesla go back and add support for Intel vehicles after it initially released a feature for AMD vehicles. We saw this with the weather radar overlay and several other features in the past. However, Tesla has been developing code with web technologies lately. While this makes development easier, it just doesn’t perform as well on the slower Intel hardware, causing it to be left out. We saw this with the new Dashcam Viewer, which is entirely coded in HTML, CSS, and JS. The new viewer was available on HW3 and HW4 vehicles, but only those that included the Ryzen infotainment processor.
Grok is coming to Tesla vehicles very soon. Next week at the latest.
There’s a lot we’re expecting in Grok for Teslas. Some people will absolutely love it because it’ll completely transform their drives from a singular experience to feeling like they have a knowledgeable person sitting right next to them. Given the recent controversies surrounding Grok, some people will strongly oppose it. Hopefully, Tesla makes it easy for those users to turn off Grok.
The voice command system, which is activated through the steering wheel, is expected to be replaced with Grok. This will mean that you’ll be able to talk to your vehicle much more naturally, rather than having to remember specific syntax and commands, which should be a major improvement.
We’re personally looking forward to just being able to ask questions that pop into our heads while driving, such as What’s the date of Tesla’s next event, or How many miles away is Mars? Knowledge will be available at the touch of a finger and more accessible than ever.
Grok is also expected to support continuous conversations, meaning that you’ll be able to hold a conversation with it and go back and forth about a certain topic. While there are hints of a wake word in the code, for now, it seems like you’ll press the steering wheel button once to activate it, and then again to turn it off.
For those excited about AI and Grok, this will be one of the biggest additions to Tesla’s software in years, possibly only rivaled by the Dashcam / Sentry Mode feature and FSD Beta.
It shouldn’t be long now before we all have a chance to try it out for ourselves.
