Model Y vs Model 3 Battery Degradation: What Real Data Shows (2026)

Model 3 vs Model Y: retention after 3 and 5 years

Original range retained

Recurrent owner data, average by model

Example data

% of original range

This chart shows published averages, not one car's data. Individual cars vary.

Averaged evenly, that's about 1.4% a year for the Model 3 and 1.0% for the Model Y, but real loss is front-loaded: a few percent in year one, then a much flatter curve.

Chemistry: LFP vs NCA vs NMC

Model 3 pack (Carla/AVILOO tests, Sweden)	Chemistry	Avg. health past 62,000 mi
CATL	LFP	93.3%
LG Chem	NMC	91.5%
Panasonic 77.8 kWh	NCA	89.8%
Panasonic 52.4 kWh	NCA	88.2%

LFP packs (common in Standard Range / RWD cars) tolerate charging to 100% and lose less capacity over time. Tesla recommends charging LFP cars to 100% at least once a week; nickel packs are best kept around 80–90% for daily use.

Why the Model Y can look better

Younger fleet. The Model Y launched in 2020, so fewer cars carry the oldest packs and highest mileage.
Bigger packs for the same use. A larger pack cycles less for the same daily miles.
Mix of chemistries differs by year and factory. Compare your exact trim, not just the model name.

Is my Model 3's battery degrading faster than normal?

Claudeused AskMyEV

Your full-charge estimate is 318 mi versus 333 mi new, about 4.5% down at 3.5 years. Published averages for the Model 3 are around 5% at three years, so you're right in the normal range.

Frequently asked questions

Which degrades faster, Model 3 or Model Y?

In Recurrent's owner data, the Model 3 averages about 93% of original range after five years and the Model Y about 95%. Both are among the best EVs measured.

Do LFP Tesla batteries last longer?

Real-world tests suggest yes. Model 3 LFP packs averaged 93.3% health past 62,000 miles in a 2026 study, versus 88–90% for Panasonic NCA packs.

What is Tesla's battery warranty?

8 years with at least 70% capacity retention; the mileage limit is 100,000 mi for Model 3/Y RWD, 120,000 mi for Long Range and Performance.

How can I check my battery degradation?

Divide displayed range by battery % to estimate range at 100%, compare with the original rated range, and track it monthly. AskMyEV can compute the trend for you.
