Figures are typical across the model's life and vary by year and trim, treat them as a guide, not a guarantee for a specific car.
How the i4's battery ages
The i4’s liquid-cooled pack has aged well in early data, with owners reporting only around 3.5 to 4% loss at 50,000 miles, a modest front-loaded drop that then settles into a slow decline. There is no pattern of premature failure, though a few early cars had packs replaced under recall, so a battery-health check and a recall check matter more than age alone.
Battery cooling is a big part of the story: this car uses active liquid cooling (bmw fifth-generation edrive) with navigation-based charge preconditioning. Cars that have spent their life on rapid chargers, been left sitting at 100%, or lived somewhere hot tend to lose capacity faster, which is why two identical i4s on the same mileage can be worth different amounts.

What to watch out for on a used BMW i4
- The eDrive35 and eDrive40 look identical but the 35 has around 13 kWh less usable battery and noticeably less range, confirm which trim you are buying
- Several 2022-2024 powertrain and high-voltage battery recalls exist, including defective packs, so check the VIN shows the recall work completed
- iDrive 8 software glitches, sat-nav bugs and CarPlay dropouts are the most common complaints, not the drivetrain
- It is a heavy car, over 2 tonnes, and the M50 runs wide staggered, often run-flat, tyres, so budget for pricey rubber and check rear wear
- Euro NCAP scored it 4 stars, marked down on safety assistance, rather than the full 5
What the Used EV Check shows for a BMW i4
Enter the registration and the Used EV Check returns, for that specific i4: its expected real-world range now versus when new, an estimated degradation figure, a battery-health grade where a manufacturer test record exists, and the battery warranty remaining in miles and months. It also pulls the full MOT and mileage history so you can spot clocking or a car that has covered far more motorway miles than the advert suggests.
It's the fastest way to tell a good BMW i4 from a tired one before you drive out to view it. For the wider process, see our complete used-EV buyer's guide and how to check an EV's battery health.
Range and battery-health figures are estimates modelled from real-world data and are shown for the specific vehicle in the Used EV Check. Range data is powered by ClearWatt. A battery-health grade is shown where a manufacturer test record exists, it is a comparative grade, not a measured state-of-health percentage.
