In an exchange on X, Drew Baglino, Tesla’s Senior Vice President of Powertrain and Energy Engineering, addressed the concerns regarding the power consumption of Tesla’s Sentry Mode. Responding to a user inquiry, Baglino confirmed the company’s commitment to reducing the feature's energy use by approximately 40% through a software update expected in Q2, which begins on April 1.
Agreed, sentry mode power consumption needs improvement, the team is working to reduce by ~40% in a Q2 software update.
This announcement follows feedback from Tesla owners regarding the 'vampire drain' experienced when using Sentry Mode, highlighting Tesla's responsive approach to customer feedback and its dedication to continuous improvement. Another X user stated that there should be a breakdown or battery usage. This information already exists, but Baglino politely responded: The energy app provides a wealth of information about where your energy goes. He also linked to our Not a Tesla App article explaining that system.

Sentry Mode is an advanced security feature for Tesla vehicles, leveraging the car’s cameras and sensors to monitor and record surroundings for potential threats when parked. Sentry Mode has proven invaluable for vehicle security by activating various deterrents, including pulsing headlights and alarm sounds.
Despite its benefits, the feature’s energy consumption, referred to as “vampire drain,” has been a concern, with estimates suggesting a small yet consistent drain on the vehicle's battery life. By optimizing Sentry Mode's power usage, Tesla enhances the feature's efficiency and extends the usability for owners, particularly when parking for extended periods without access to charging facilities.
Battery Management: Recognizing the importance of battery preservation, Sentry Mode automatically deactivates when the battery level falls to 20%, ensuring that the vehicle remains operational for essential travel.
Activation and Customization: Owners can activate Sentry Mode via the vehicle's touchscreen or mobile app, with options to customize settings, such as disabling sounds or excluding specific locations, tailoring the security feature to individual preferences and requirements.
Tesla's forthcoming software update aims to significantly reduce Sentry Mode's power usage, making it more adaptable for various situations without impacting the car's range or battery longevity. This enhancement aligns with Tesla's commitment to continuous improvement via over-the-air updates, directly responding to customer feedback with practical solutions. Owners looking forward to this change appreciate the balance between maintaining Sentry Mode's security benefits and preserving battery life for everyday needs.

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.
However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.
What is LiDAR?
LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.
Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.
While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.
Why Does Tesla Use LiDAR?

Not a Tesla App
At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.
Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.
While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.
Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.
Why the Delay?
The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.
If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.
Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.
A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.
Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?
While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.
Is the Delay Accurate?
We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.
Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
