💡 Skip to the Deal: Get Tessie with your Tesla – always get the best price with this link
Want to monitor your Tesla’s battery health without heading to a service centre? With the Tessie app, you can get real insights into your vehicle’s battery condition straight from your phone in just 2 minutes, with no appointments and no hassle.
Tesla owners have long wanted a way to monitor battery degradation at home. Tessie delivers exactly that, estimating your battery health by analysing charge cycles, range, and real-world usage compared to factory benchmarks.
Why Battery Health Matters
Your Tesla’s battery is one of its most valuable components. Over time, all EV batteries experience a bit of degradation, usually around 1-3% per year. Knowing how your battery is performing helps you:
- Understand range changes
- Track long-term performance
- Show potential buyers real data
- Spot early warning signs of issues
Tessie visualises this clearly, with simple, easy-to-read graphs showing your battery’s current capacity and trends over time.
How Tessie Tracks Battery Health
Tessie uses secure, read-only access to your Tesla account to gather charging data, trip history, and energy usage. Then it runs calculations to estimate battery health and displays:
- Current vs. new battery range
- Charge cycles and trends
- Degradation over time
- How your battery compares to other Teslas of the same model and age
Uop till now, this kind of insight required you to run a test that would take up to 24 hours. Now, you can access it anytime, from anywhere.
Fully Compatible with 2026 Models
Tessie is fully compatible with the latest Tesla Model 3 Highland and Model Y Juniper 2026 editions, making it the perfect companion for new owners wanting to track battery health from day one.
Is Tessie Accurate?
While Tessie can’t replace a full Tesla diagnostic report, it provides one of the most reliable at-home insights available today. It’s especially useful if you:
- Want to monitor how your charging habits affect battery life
- Are preparing to sell your Tesla
- Just love diving into real EV performance data
More Than Just Battery Health
Tessie is packed with other useful features, too:
- Full trip and charging analytics
- Smartwatch controls
- Sentry tracking
- Automation tools (set charging limits, climate control, remote actions)
💡 Why I Checked My Battery Health the Moment I Got My Model 3
I bought my Tesla Model 3 Long Range from Cinch in April 2026 – it had 44,000 miles on the clock at delivery. One of the first things I did was connect Tessie to get a baseline reading of the battery's actual condition against the fleet average for similar vehicles. Having that data from day one has been genuinely useful: I can now track the trend as the mileage climbs toward 59,500, and that history is exactly the kind of evidence a future buyer would want to see before purchase.
