Tesla has begun rolling out its version 2025.8.3 update to the first batch of vehicle owners, bringing significant improvements to battery monitoring and energy consumption tracking. Update introduces tools that have been long requested by the Tesla community, particularly those focused on battery health transparency.
The update adds a comprehensive battery health testing feature, allowing owners to measure their battery’s current energy retention compared to when it was new. Marks a shift in Tesla’s approach to battery degradation metrics, giving users more direct access to information about their vehicle’s most critical component.
The new Battery Health Test feature appears in the vehicle’s service menu (Controls > Service > Battery Health) and provides owners with the ability to run diagnostics on their battery pack. This feature is especially valuable for long-term Tesla owners who can now quantitatively compare their battery’s current performance against its original specifications.

Running the test may recalibrate the battery’s energy estimates, potentially affecting the range indicator displayed on the vehicle. Recalibration addresses a common issue where displayed range might not accurately reflect actual battery capacity due to gradual degradation.
The Tesla version 2025.8.3 update also revamps the Consumption page, allowing owners to view energy usage data across different distance metrics. Users can now track their last 10, 100, or 200 miles (15, 150, or 300 kilometers) of energy consumption, with the option to clear this history as needed.
Additionally, the battery’s energy estimate now accounts for individual vehicle usage patterns and will continuously adjust based on driving history. This personalized approach should provide more accurate range predictions tailored to each owner’s driving style.
Tesla’s approach with the ver 2025.8.3 update continues its philosophy of transparent reporting on battery performance. Unlike some manufacturers who maintain static range figures despite actual battery wear, Tesla has chosen to show owners the unvarnished reality of their battery’s condition.
This transparency creates an interesting tension – while owners want access to degradation information, facing the actual numbers can sometimes be disappointing. The new Battery Health Test doesn’t sugar-coat the reality, which might prove initially challenging for some owners to accept.
For Tesla owners wanting to test their battery’s health, this update finally puts the power in their hands – even if the results might drain some expectations.
