InsideEVs has reported on a 2023 Tesla Model 3 Rear-Wheel Drive in Maui, Hawaii, revealing that even Tesla’s lithium iron phosphate (LFP) battery chemistry is not immune to degradation. Despite LFP’s reputation for durability and tolerance to frequent full charges, the tested vehicle showed more capacity loss than many owners might expect at this mileage.
Battery Health Results from Real-World Use
YouTuber Branden Flasch tested the battery health of a rented 2023 Tesla Model 3 Rear-Wheel Drive with an LFP battery in Maui. The Tessie app initially estimated the car retained 92.27% of its original battery capacity after 253 charge-discharge cycles. However, Tesla’s built-in battery health test, which involves a full discharge and recharge while plugged in overnight, gave a more conservative result: 90% battery health and a usable capacity of 55.62 kWh.
This level of degradation is higher than many expect for an LFP-equipped Model 3 with under 26,000 miles (~41,800 km), especially given the chemistry’s reputation for longevity.
Factors Affecting Battery Degradation
The Model 3’s life as a rental vehicle may have contributed to its battery wear. Rental cars are often charged to 100% and may see frequent fast charging. In Maui, the most common public fast charger is rated at 50 kW, but a 12-stall Tesla Supercharger is also available, potentially allowing for regular high-speed charging.
The tropical climate of Maui could also play a role, as higher ambient temperatures can accelerate battery degradation. Branden noted that the car showed higher-than-average electricity consumption, possibly due to the climate system working harder to maintain cabin comfort.
Comparison with Other Tesla Models
Branden compared the rental Model 3’s results with his wife’s 2025 Tesla Model Y Long Range Rear-Wheel Drive, which uses a nickel manganese cobalt (NMC) battery. That vehicle showed 88% battery health after about 13,000 miles (~20,900 km).
A separate case from Europe involved a three-year-old Model Y Standard-Range with an LFP battery, which had covered 34,000 miles (~54,700 km) and retained 92% of its original capacity. Notably, this European Model Y lost only 1% capacity over the last year, suggesting that degradation rates can slow over time.
Competitor Comparison
The Tesla Model 3 competes with other electric sedans such as the Hyundai Ioniq 5, Polestar 2, and BYD Seal. While LFP batteries are praised for their cycle life, real-world results like those from the Maui rental Model 3 highlight that usage patterns and environmental factors can significantly impact battery longevity across all brands.
Historical Context
Tesla’s global vehicle sales reached 10.4 million units in 2024, with a 10% year-over-year decline at that time. However, the broader U.S. auto market has seen a 7.8% increase in sales as of June 2026, reflecting ongoing consumer interest in electric vehicles despite concerns about battery longevity.
Why this matters
Battery degradation is a key concern for EV owners and prospective buyers, as it directly affects range and long-term value. The findings from this 2023 Model 3 suggest that even with robust LFP chemistry, real-world factors like frequent fast charging, rental use, and hot climates can accelerate capacity loss.
Understanding how different battery chemistries perform under various conditions helps buyers make informed decisions and manage expectations about EV ownership.
What this means for buyers
Prospective EV buyers should consider not just the battery chemistry, but also how the vehicle will be used and the local climate. Rental vehicles or those frequently fast-charged may experience faster degradation, even with LFP batteries. Regular monitoring of battery health and adapting charging habits can help preserve capacity over time.
