Tesla’s battery health and longevity have recently been revealed to be quite good as shown in their latest Impact Report. However, on rare occasions, you may still encounter problems or degradation, and it is worth knowing how to self-diagnose potential issues without needing to reach out to Tesla Service, at least as a first step.
Tesla offers two ways to test your vehicle’s battery health. One is a quick self-test that highlights any issues, while the other one takes much longer, but offers a detailed view of your battery’s health.
Battery Health Check in the Tesla App
Battery health check in the Tesla app
Not a Tesla App
You can open up your Tesla app and go to the ‘Service’ section on the main screen.
You can then tap “Request Service”, choose “Battery & Charging”, and finally “Range”. If you’re prompted to pick a service center, go ahead and pick any service center first. You’ll then be asked to describe the concern. You can type in “range” or any other text and then tap Next at the bottom.
Keep in mind this is an automated solution and your request won’t actually go to a service center when you tap Next.
The app will perform a quick self-diagnosis to see if your battery is within the normal range of degradation. This is a quick self-test and just lets you know that you’re well within Tesla’s expected battery degradation levels.
Thorough Battery Health Test in Service Mode
If you want a more detailed analysis, you can open Service Mode using our instructions. Navigate to the High Voltage menu and then tap on ‘Health Test’ in the ‘HV Battery’ section.
The battery health test in Service Mode is more in-depth and can take up to 24 hours – or more – depending on your charging setup. You’ll need to be plugged in – and not at a Supercharger.
The slower your means of charging, the longer the test will take. However, expect it to take at least 12 hours at minimum, and more than 48 hours if you’re charging a Long-Range vehicle at a lower amperage.
How the Service Mode Battery Health Test Works
The best time to run the Service Mode test is when your battery is closer to empty, rather than full – otherwise the car will need to spend time wasting energy to drain the battery.
Once it reaches a low enough state of charge, the car will then charge up to 100%. Once that completes, go back to the High Voltage section in Service Mode and the vehicle will display a Battery Health percentage.
According to Tesla, Tesla batteries degrade about 15% after 200k miles (321k km) on average. Much of the degradation is front-loaded, meaning that degradation happens faster when the vehicle is newer and the degradation then tapers off.
Note that running the battery health test should be used sparingly and mostly only if you suspect there may be an issue with your battery. By running the test you’re increasing the number of charge cycles on your battery and thus causing some additional degradation. One time won’t hurt it, but doing it often would not only degrade your battery but also increase your electric bill.

Below is a chart Tesla shared on the Model 3 and Model Y’s battery retention. It can be used to compare your results to Tesla’s findings.
Tesla recommends keeping the state of charge of your battery between 40%-80%, depending on the vehicle. Vehicles with LFP batteries are recommended to be charged to 100%.
While Tesla supports a variety of music streaming services, including YouTube Music, Apple Music, and Spotify, there may be times you want to listen to music from a local USB drive.
While Bluetooth is also an option, it’s limited to what’s available on your phone and the lower streaming quality of Bluetooth.
In this guide, we’ll go through the benefits of having music on a USB drive and how to set it all up.
Benefits of Music on a USB Drive
Having music stored locally has several benefits. First is audio quality; since you’re under full control of the bitrate of the content, you can encode or buy music at much higher quality when compared to steaming content from Spotify or another streaming service. Tesla even supports FLAC’s lossless audio, letting you experience the best audio experience in your vehicle.
Local music also doesn’t require an internet connection, so if you frequently traffic through areas with a spotty connection, you may prefer to have music locally on hand.
While streaming content is convenient, you can be limited by the content that’s offered. If you prefer foreign music or other music that’s not available on a music service that Tesla supports, local content could be a great option.
Lastly, having music on a USB drive is a great option if you don’t subscribe to a music streaming service or don’t pay for Premium Connectivity in your Tesla.
Step 1: Use the Right USB Port
Not all USB ports in a Tesla support data transfer. While some models have USB data ports in the rear console or center console, they do not support media playback and can only be used to charge a device.
Instead, your best bet is to use the USB port inside the glovebox, which is designed for both dashcam video storage and music playback. While some vehicles may also support data transfer through the USB ports in the front console, not all of them do. Older vehicles may not have a USB port in the globebox, and you’ll be limited in using the USB ports in the console.
Important: You cannot play music from a phone, tablet, or external music player over USB—only from a properly formatted USB storage device.
Step 2: Format Your USB Drive
Every new Tesla comes with a high-speed USB drive pre-installed in the glovebox, formatted for Sentry Mode and Dashcam storage. If your vehicle didn’t come with one, or you want to use a larger or separate drive for Sentry Mode or music, you’ll need to format it first.
How to Format a USB Drive in Your Tesla
Insert your USB drive into the desired USB port.
Navigate to Controls > Safety > Format USB Drive
Wait a few seconds (it may take longer for large drives), and the system will format the drive and create the necessary folders (e.g., for Sentry Mode and Track Mode).
💡 Tip: Use a high-speed, high-capacity SSD for the best experience. Regular flash drives work, but SSDs provide faster loading times and more capability.
Step 3: Add Your Music
Once your USB drive is formatted, unplug the USB drive from your Tesla and connect it to your computer to add your music files.
Organizing Your Music:
Create a folder called Music at the top level of the USB drive. All music must be added to this folder.
You can organize the music however you prefer, and you’ll be able to view the folders in the vehicle when selecting music. Most users prefer to have folders that include the name of the artist with subfolders for the album name, but how you organize the content is completely up to you.
If your music files content metadata such as song title, artist, album, etc, it will automatically be displayed in Tesla’s media player.
Supported Audio Formats
Tesla’s music player supports a variety of audio formats, including wave, MP3, and FLAC (lossless), but it does not support AAC (Apple's iTunes format). If you have AAC files, you can convert them to MP3 or FLAC before transferring them.
Step 4: Play Your Music
Not a Tesla App
Once you’ve transferred your music, you can bring it back to your Tesla.
Insert the USB drive into the front console or glovebox port.
You’ll now have a new app under the all apps menu called USB.
The USB app will let you view all of your supported audio content on the USB drive. You’ll be able to view the content by song, artist, album, genre, and folder structure.
First-time indexing of audio content may take a few seconds (longer for larger drives). Tesla re-indexes the drive every time the car wakes from sleep, so keeping the total file size under 30GB ensures faster access.
Voice Commands and Search
While music stored on the USB drive will behave much like other content that’s played over streaming services, there are a few limitations.
Voice commands can not be used to play a specific song or artist from your USB drive. If you ask the vehicle to play any content, it’ll default to one of the music services.
Music search is also not supported. While search will show content from all music services that aren’t hidden, it will not include music from your USB drive.
Enjoy the Best Sound Tesla Has to Offer
Tesla’s audio system is meticulously engineered for a premium sound experience, and playing lossless audio over USB takes full advantage of that. If you’re an audiophile, this setup ensures you hear your music in its purest form—no compression, no interference, just crystal-clear sound.
Another month brings another exciting update packed with Cybertruck news. Grab your stainless steel mug and join us as we dive into the latest developments, from new features to upcoming products—all things Cybertruck.
This recap covers news from early January to early February, keeping you updated on the latest updates and what’s coming next for the Cybertruck.
Off Road Armor & Rockers Coming Soon
The prototype Off Road Armor in all its glory.
Not a Tesla App
Back in 2024, Wes Morril (Cybertruck’s Lead Engineer) and Siddhant Awasthi (Cybertruck’s Program Manager) teased the arrival of off-road armor, expected to launch for customer purchase in Winter 2024. Unfortunately, that hasn’t materialized.
But there’s good news. Wes recently showcased the prototype off-road armor and side rockers, confirming they’re on the way. Tesla plans to add them to the store by the end of March. Pricing details are still unknown, but since this armor covers the entire underbody of the Cybertruck, it’s safe to assume it won’t come cheap.
Wheel Cover Supply Confirmed
Tesla has been working hard to get Cybertruck wheel covers to early owners. While new deliveries now come with them pre-installed, some customers— including those who received their Cybertrucks as far back as March 2024—are still waiting.
According to Siddhant Awasthi, Tesla has secured a supply of the covers, but distribution remains a challenge. So far, about 32% of eligible owners have received theirs, with more shipments on the way.
In the meantime, Tesla is offeringcomplimentary Cyber Wheel Caps to owners still waiting for their covers. These will be sent out for free, with email notifications already rolling out.
Air Suspension Controls and Improvements
Strangely, the Cybertruck still lacks the ability to control vehicle height from the app—a feature that would be incredibly useful for off-roading and just cool to have in general.
The good news is that Siddhant Awasthi recently hinted that improvements to the air suspension controls are on the way, along with other unannounced feature upgrades.
Could this mean more advanced vehicle leveling, finer height adjustments, or even the ability to drive in High mode at faster speeds? We’ll have to wait and see, but we’re definitely excited to find out.
Cold Weather Update Delayed
The Cybertruck continues to face regen and charging issues, and although a fix may arrive in update 2025.2, that update has yet to hit the Cybertruck.
We reached out to Tesla Service for an update. While they previously stated the fix would land in 2025.2, they now say it’s “coming soon,” so it’s unclear whether we’ll even get those fixes this winter.
RWD Cybertruck Coming Soon, EV Rebate Available Now
In case you missed it, the RWD Cybertruck is expected to arrive soon, and the Dual Motor variant now qualifies for the Federal EV Rebate in the U.S.
The RWD model will likely launch with a few feature omissions, including:
• A manual tonneau cover instead of an automatic one
• Potentially optional PowerShare functionality
• Internal and rear AC outlets may also be missing
