These curves are aggregated, owner-reported degradation data — not official manufacturer figures. Your own result above is the number that matters.

How to find these values on your Tesla

Wh/mi or Wh/km

Tap the car icon on the touchscreen, then go to "Trips". Your average Wh/mi (or Wh/km) is shown for each trip segment. Alternatively, open the "Energy" app from the app launcher — consumption is displayed at the top of the screen.

Estimated Range

Estimated range is displayed at the top of the touchscreen (or on the instrument cluster for Model S/X). In the Energy app, projected range based on recent driving is shown at the right side of the graph.

Battery Percentage

Battery percentage is shown at the top of the touchscreen next to the battery icon. If you see miles/km instead, tap the battery icon or go to "Controls" → "Display" → toggle "Energy Display" to "Percentage".

Tesla Model S battery degradation — what to expect

~91%

Fleet average at 100,000 mi

Real-world fleet data across thousands of Model S vehicles shows remarkably consistent retention — one of the best long-term EV battery track records.

~88%

Fleet average at 200,000 mi

The degradation curve flattens significantly after the first 50,000 miles. Many high-mileage Model S owners report no meaningful impact on daily driving.

8 yr / 150k mi

Warranty period (all trims)

All Model S variants: 8 years or 150,000 miles, minimum 70% capacity retention.

The Model S has one of the best long-term battery track records of any EV. Early 18650-cell vehicles (2013–2016) showed slightly higher initial drops, but the curve flattens quickly. Newer 2170-cell variants (Long Range, Plaid) maintain capacity even more consistently. High-mileage Model S vehicles — 200,000+ miles — remain common and functional.

Charging tip

Set your daily charge limit to 80–90%. Supercharger use is fine for travel but heavy reliance on DC fast charging accelerates degradation over time.

Cell chemistry determines how you should charge. LFP owners can charge to 100% daily; NMC owners should stay at 80–90% for daily use.

Cell format

Model S: 18650 (2013–~2020), 2170 (newer variants). Battery capacity ranges from <strong>62–98 kWh</strong> depending on trim and model year.

About the Tesla Model S

The Tesla Model S is the car that proved electric vehicles could be desirable, fast, and practical. Now in its refreshed 'Plaid' form, it offers supercar-rivalling performance with a 0–62 time of 3.2 seconds (the Plaid manages it in under 2 seconds) combined with over 400 miles of WLTP range.

The controversial yoke steering wheel divided opinion when it launched, though a conventional wheel is now available. The 17-inch central screen, gaming-capable infotainment, and minimalist interior either delight or frustrate depending on your taste.

At its price point, it competes with the Mercedes EQS and BMW i7. It remains the performance benchmark for electric saloons, though newer rivals have caught up on interior quality and ride refinement.

What the press thinks

The Model S is still lauded for its extraordinary performance and range. The Plaid variant is considered one of the fastest production cars ever made. Critics note the interior, while improved, still lacks the luxury feel of Mercedes and BMW alternatives at this price point.
